tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "modified signature - R"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "modified signature - SIGHT"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "modified signature - R"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "invalid signature - too small"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "invalid signature - too large"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "valid signature and message - signature should verify successfully"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction

dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "invalid signature - too large"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "invalid signature - too small"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "modified signature - SIGFORS"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"deferred" : false ,
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "modified message"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"additionalRandomness" : "B0541392FBEBDF69C7BE1EC9A6008B11" ,
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "modified signature - SIGHT"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "valid signature and message - signature should verify successfully"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "invalid signature - too large"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "valid signature and message - signature should verify successfully"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "modified signature - SIGHT"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "modified signature - R"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "valid signature and message - signature should verify successfully"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "modified signature - SIGFORS"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "modified message"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "modified signature - R"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "modified signature - SIGHT"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "modified signature - SIGFORS"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "invalid signature - too small"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "invalid signature - too small"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"deferred" : false ,
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "modified message"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

External review flagged across rounds 4-6 that the empirical evidence tying the

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "modified message"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"hashAlg" : "none" ,
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "valid signature and message - signature should verify successfully"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

"hashAlg" : "none" ,
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "modified signature - SIGFORS"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer

domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,

Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE

never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "invalid signature - too large"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"additionalRandomness" : "77F52C9E739166D8E2A09B08B713BCA1" ,
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

External review flagged across rounds 4-6 that the empirical evidence tying the

rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO

VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json

domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "invalid signature - too small"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"additionalRandomness" : "FD4C2A3F4098BB41C4FAEEC1AE9A7E3A" ,
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "modified signature - SIGFORS"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"hashAlg" : "none" ,
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "invalid signature - too large"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"hashAlg" : "none" ,
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "invalid signature - too small"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"hashAlg" : "none" ,
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "modified signature - SIGHT"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"hashAlg" : "none" ,
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge

External review flagged across rounds 4-6 that the empirical evidence tying the

corruption always at byte 100), and the ACVP vectors vendored here contain NO

campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json

method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large

with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono

Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test

requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "modified signature - R"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer

vectors: make the extraction re-derivable and the provenance claim literally true
Round-7 review (both reviewers, independently) found that the ACVP provenance
note said "the per-test private key `sk` dropped ... Nothing else altered" while
the extraction had in fact also dropped `additionalRandomness` and `deferred`
from all 42 tests, plus the top-level `isSample`. No field the tests consume was
affected and no verdict changed — but the provenance block is the audit trail a
third party diffs against, and as written it would have produced a false alarm
or taught the next reviewer to wave differences through.
Rather than reword the note, the transformation is now executable and pinned:
tests/nist_acvp_vectors/extract_sha2_128s.py re-derives the file, verifies the
upstream sha256 before doing anything, requires exactly 3 groups x 14 tests,
removes exactly ONE field (`sk`) and asserts that invariant, carries every other
per-test, group and top-level key through untouched, and writes canonical
output. Run with no arguments it VERIFIES the committed file against a fresh
extraction; --write regenerates. The file was regenerated with it, so
"only `sk` removed" is now literally true and machine-checkable.
Also from round 7, precision in the tests themselves:
- exact assertions replace floors: `points == 108` (was >= 100),
`with_ctx == 9` (was > 0), and prehash `3/4/7` (was `checked > 0`). With 7 of
14 prehash vectors skipped for unimplemented hash functions, a floor would
have let real coverage fall from 3 to 1 while the total still summed to 14.
- the randomized bridge's doc comment claimed corruption "across the WHOLE
signature"; measured, the schedule hits 72 distinct positions in 11..=7779,
never bytes 0-10 or 7780-7855. Corrected to the measured statement.
Verified on stable Rust (rustc 1.95) as well as the pinned nightly: the bridge
needs no nightly feature, so a third party can run all of it with cargo alone.

"reason" : "modified message"
tests: NIST ACVP SHA2-128s verification KATs + a real differential bridge
External review flagged across rounds 4-6 that the empirical evidence tying the
proved model to the deployed code had not moved by a single data point in six
rounds: the sole bridge was nine assertion points (3 rounds, one fixed seed,
corruption always at byte 100), and the ACVP vectors vendored here contain NO
SLH-DSA-SHA2-128s sigVer group at all — the one parameter set this verification
campaign is about had zero NIST known-answer verification coverage.
VECTORS. tests/nist_acvp_vectors/SLH-DSA-sigVer-FIPS205/sha2_128s_extracted.json
carries the three SHA2-128s sigVer groups extracted verbatim from the official
NIST ACVP-Server vector set (source URL, upstream file sha256 and extraction
method recorded in the file's own _provenance block; per-test private keys
dropped as unnecessary to verify). 42 tests: 2 valid and 12 negative per group,
the negatives spread over structurally distinct corruption sites — modified R,
modified SIGFORS, modified SIGHT, modified message, too-small and too-large
signatures.
TESTS (all in src/verify_mono.rs, so they exercise the monomorphic path the Lean
certificates are about):
- mono_matches_nist_acvp_128s_internal — NIST's `internal` group carries M'
directly, which is exactly what slh_verify_128s consumes, so these are true
known-answer tests OF THE PROVED PATH: 10 executed, 4 attributed to
deserialization (wrong-length signatures, rejected above the extraction root).
Accounting is exact — all 14 are accounted for, nothing silently skipped.
- mono_matches_nist_acvp_128s_external_pure — builds M' the way lib.rs does and
requires mono, the deployed verifier and NIST to agree: 10 executed, 9 of them
with a NON-EMPTY context. This is the first empirical check of the
domain-separator byte and context-length prefix that TRUSTED-BASE item 10
declares outside every proof.
- deployed_matches_nist_acvp_128s_prehash — validates the deployed prehash path
for 128s: 3 executed, 4 wrong-length, and 7 skipped because NIST exercises
prehash functions (SHA3-*, truncated SHA2) this crate's `Ph` enum does not
implement. Counted and reported rather than hidden.
- mono_matches_deployed_randomized — replaces the fixed-seed/fixed-byte bridge:
12 rounds, varying message lengths including empty, corruption spread across
the WHOLE 7856-byte signature, plus wrong-public-key and wrong-context cases
that were never exercised before. 108 assertion points, each requiring mono
and deployed to agree.
Bridge coverage: 9 assertion points -> 131, of which 20 are NIST known-answer
tests on the proved path where there were previously none.
No change to any verify-path function: this commit touches test code and test
data only, so the Charon/Aeneas extraction is unaffected (verified separately by
re-running extract.sh and diffing the generated model).
