verification: pin the harness, the audit drivers and the policy files (P1-c)
Every gate this repository has was executed by scripts that nothing pinned.
Round-5 review of the companion SLH-DSA repository stubbed the compiler
wrapper alone and its button printed ALL GREEN in 3.6 seconds over
deliberately destroyed proofs; flipping two guards in the audit driver
disabled every check with the digest byte-identical. Depth of checking is
worth nothing if the thing doing the checking is unbound — and every gate
added this week made that gap more valuable to an attacker, not less.
Phase 0c requires every harness file to match HARNESS.sha256. Two design
points carry the weight:
- WHICH files must be pinned is POLICY and lives in check.sh, never in the
map being consulted. If the required set were read from the pin file,
deleting an entry would silently un-pin that file. It is instead derived
from the filesystem, so a deleted entry is a set mismatch and a build
failure. That is the exact defect SLH-DSA round-6 found, closed here by
construction.
- Membership self-derives from the executable bit: anything this script can
shell out to must be pinned, so a NEW script fails closed until someone
pins it deliberately. Load-bearing files that are not executable — the
audit driver, the committed manifests, the policy tables — cannot be
discovered that way and are listed explicitly.
lean-guard is inside the set, which finally makes the standing "lean-guard
stays hash-pinned" rule a property of the repository rather than a convention.
selftest-harness.sh replays five cases, each asserting a specific diagnostic:
an edited lean-guard, a new unpinned executable, a deleted pin entry, a
missing pin file, and a positive control. It was itself negative-tested — with
the hash comparison removed it goes red on exactly that case while cheerfully
reporting "10 harness files match their pins".
TRUSTED-BASE.md states the limit at equal length to the claim: pinning a
harness from inside that harness is circular, and an author who edits a script
and refreshes its pin in the same commit passes every phase. What the pin
changes is that the edit can no longer be SILENT — it must appear in the diff
at the commit being reviewed. A green button says "this is the apparatus that
was reviewed", never "this apparatus is trustworthy".
Also fixed, found by this sweep: both self-tests compared the working tree
against its starting state with `diff <(echo "$VAR") <(command)`, which is
asymmetric — for a clean tree the variable is empty and `echo` emits a blank
line the command does not. It reported a difference precisely when nothing was
wrong, and only surfaced once P1-a was committed and Proofs/ became clean.
Both now compare as strings.
Verified green: 20 runs across the four ed25519 repositories (four buttons,
four harness self-tests, four axiom-gate self-tests, four binding self-tests,
four scalar buttons), zero red.

verification: close the two-button seam and level up the scalar button (P0-b)
THE SEAM. This repository is checked by two scripts, and until now neither
asserted anything about the other's scope. check.sh's dead-file gate simply
SKIPPED anything named Scalar*, so a new Proofs/ScalarX.lean was gated by
nothing at all: absent from one manifest by exemption, from the other by
omission, compiled by neither, inventoried by neither. Each button now reads
the other's manifest and requires every shipped proof source to belong to
EXACTLY ONE of them — neither orphaned nor double-claimed, both directions,
plus a phantom check on entries naming files that do not exist. Negative-tested
four ways, including the exact hole this item names.
THE SCALAR BUTTON. Closing the seam exposed it as the estate's weakest link,
having been left behind by every hardening round while the main button gained
five phases. 45 lines to 227:
- source-integrity check over its sources;
- harness-pin verification, so running THIS button alone is protected and not
only running it after check.sh;
- a kernel-side axiom-declaration gate over the compiled artifacts, replacing
a source-text grep that is evadable four ways on v4.30.0-rc2;
- a declaration inventory of ~1880 constants against its own allowlist,
diffed both directions with a count trailer. These 13 modules were the only
part of the proof corpus with no inventory: check.sh Phase 2c named them as
uncovered on every run, and now names the button that covers them instead;
- per-certificate exact-cone assertions replacing `-eq 13` over matching
output lines. A count cannot say WHICH certificate is clean and passes just
as happily if one cone is reported twice.
Every fork-specific fact was read from the existing script rather than assumed:
risc0 and betrusted audit sub_loop1_one_spec where dalek and anza audit
cond_add_l_one_spec, untouched.
THREE BUGS, ONE ROOT CAUSE, all found by the gates rather than by review. Each
reasoned about how a thing is SPELLED instead of what it BELONGS TO, and the
corpus punished each: Proofs/ScalarPackSpec.lean is named like the scalar layer
and owned by the main button.
- the scalar dead-file gate globbed Scalar* and demanded ScalarPackSpec be
scalar-owned. REMOVED rather than special-cased: the seam check tests
membership in exactly one manifest, which is strictly stronger than any
prefix;
- the scalar axiom gate scanned Scalar*.olean, reporting "14 modules" for a
13-module manifest. On a tree where check.sh had not run that artifact is
absent and the button would have failed for a false reason. It now scans
the manifest by membership and fails closed on a missing artifact;
- Phase 2c's driver discovery globbed Inventory*.lean and claimed the other
button's driver, then correctly complained its own manifest lacked those
modules.
This is the family the campaign began with: a source-text axiom grep reasoning
about spelling. Recorded in TRUSTED-BASE.md because it generalises.
Also fixed: the first negative test of the scalar gate's absence check passed
for the wrong reason — the button recompiles before the gate runs, so removing
an artifact merely caused it to be rebuilt. Retested against the lifted phase,
where absence is a persistent condition.
Verified green: 24 runs across the four repositories — four main buttons, four
scalar buttons, and sixteen self-tests — zero red.

verification: pin the whole declaration surface (P1-b)
Phase 2b asks the kernel whether any AXIOM is declared under Proofs/. Phase 3
pins the cones of the named certificates. Between them sat every other
declaration in the corpus — around three thousand of them — and a helper lemma
quietly acquiring a hash oracle in its cone moved nothing either phase looked
at.
Phase 2c closes that. Ported from ltl-accumulator-verified, where a nine-attack
self-test proved a source-regex enumerator evadable by attributed, private,
indented and `instance` declarations and by a nested-namespace basename
collision. Reading the compiled environment sees what the kernel saw; no name
shape hides. Every constant contributes module, name, kind and full axiom cone,
and the observed set must equal inventory-allowlist.txt exactly in BOTH
directions, with a count trailer so a truncated run cannot pass as an empty
diff.
FOUR THINGS THIS BUILD GOT WRONG, each caught by a check rather than by review:
- The number of inventory drivers is a per-repo FACT, not an assumption.
dalek and anza cannot import their corpus as one environment (Proofs.Basic
and Proofs.ConstSpecs both declare CurveFieldProofs.zero_spec); risc0 and
betrusted have no Proofs.Basic at all. Determined by compiling a probe.
check.sh now DISCOVERS its drivers from the filesystem instead of naming
two, and the generator refuses to split out a module the repo lacks.
- The split let one real declaration hide behind another's entry. Keyed on
name alone, the two zero_specs produced byte-identical records, so 3022
declarations were covered by 3021 allowlist entries. Caught by the count
trailer. Every record now carries its originating module.
- The gate's success line said "single sanctioned axiom", inherited from the
accumulator's policy. This corpus permits NONE. A success message
describing a different rule is how an assertion stops meaning anything.
- selftest-axgate.sh lifted Phase 2b with a range ending at "Phase 3", so
inserting Phase 2c between them made it swallow the new phase and die on
variables only check.sh defines — surfacing as the BASELINE case failing,
a self-test blaming a gate for its own extraction bug. Both self-tests now
stop at the next phase marker whatever it is called, and refuse to run if
they capture more than one phase. The guard is the fix; the range was the
symptom.
WHAT THIS IS NOT, recorded in TRUSTED-BASE.md at the same length as the claim:
- No independent cone walker. The accumulator cross-checks collectAxioms
against a hand-written walker. Ported here it was wrong in BOTH directions
on mathlib's inductive shapes: EdPoint gave [] against the kernel's three
axioms, and once extended, ProjPoint gave three against the kernel's none.
Two implementations disagreeing both ways are a second wrong answer, not a
check. These cones rest on collectAxioms alone.
- Thirteen Proofs/Scalar* modules are inventoried by nothing — the
second-button seam, still open. Phase 2c names every uncovered module on
every run so the omission is visible rather than inferred.
selftest-inventory.sh exercises the shipping gate with six cases, each
asserting a specific diagnostic, including the one that matters: a cone
widened by one oracle while name, module and kind stay put. Negative-tested by
disabling the gate's diff, which turns two cases red including one for the
wrong reason, correctly reported as such.
Verified green: 20 runs across the four repositories (four buttons, four
harness, four inventory, four axgate, four binding self-tests), zero red. The
four check-scalar.sh greens from the preceding sweep stand: that script neither
reads the pin file nor changed.

nothing at all: absent from one manifest by exemption, from the other by
omission, compiled by neither, inventoried by neither. Each button now reads
the other's manifest and requires every shipped proof source to belong to
EXACTLY ONE of them — neither orphaned nor double-claimed, both directions,
plus a phantom check on entries naming files that do not exist. Negative-tested
four ways, including the exact hole this item names.
THE SCALAR BUTTON. Closing the seam exposed it as the estate's weakest link,
having been left behind by every hardening round while the main button gained
five phases. 45 lines to 227:
- source-integrity check over its sources;
- harness-pin verification, so running THIS button alone is protected and not

- a kernel-side axiom-declaration gate over the compiled artifacts, replacing
a source-text grep that is evadable four ways on v4.30.0-rc2;
- a declaration inventory of ~1880 constants against its own allowlist,
diffed both directions with a count trailer. These 13 modules were the only
part of the proof corpus with no inventory: check.sh Phase 2c named them as
uncovered on every run, and now names the button that covers them instead;
- per-certificate exact-cone assertions replacing `-eq 13` over matching
output lines. A count cannot say WHICH certificate is clean and passes just
as happily if one cone is reported twice.
Every fork-specific fact was read from the existing script rather than assumed:
risc0 and betrusted audit sub_loop1_one_spec where dalek and anza audit
cond_add_l_one_spec, untouched.
THREE BUGS, ONE ROOT CAUSE, all found by the gates rather than by review. Each
reasoned about how a thing is SPELLED instead of what it BELONGS TO, and the
corpus punished each: Proofs/ScalarPackSpec.lean is named like the scalar layer
and owned by the main button.
- the scalar dead-file gate globbed Scalar* and demanded ScalarPackSpec be
scalar-owned. REMOVED rather than special-cased: the seam check tests
membership in exactly one manifest, which is strictly stronger than any
prefix;
- the scalar axiom gate scanned Scalar*.olean, reporting "14 modules" for a
13-module manifest. On a tree where check.sh had not run that artifact is

the manifest by membership and fails closed on a missing artifact;
- Phase 2c's driver discovery globbed Inventory*.lean and claimed the other
button's driver, then correctly complained its own manifest lacked those
modules.
This is the family the campaign began with: a source-text axiom grep reasoning
about spelling. Recorded in TRUSTED-BASE.md because it generalises.
Also fixed: the first negative test of the scalar gate's absence check passed
for the wrong reason — the button recompiles before the gate runs, so removing
an artifact merely caused it to be rebuilt. Retested against the lifted phase,
where absence is a persistent condition.
Verified green: 24 runs across the four repositories — four main buttons, four
scalar buttons, and sixteen self-tests — zero red.

FOUR THINGS THIS BUILD GOT WRONG, each caught by a check rather than by review:
- The number of inventory drivers is a per-repo FACT, not an assumption.
dalek and anza cannot import their corpus as one environment (Proofs.Basic
and Proofs.ConstSpecs both declare CurveFieldProofs.zero_spec); risc0 and
betrusted have no Proofs.Basic at all. Determined by compiling a probe.
check.sh now DISCOVERS its drivers from the filesystem instead of naming
two, and the generator refuses to split out a module the repo lacks.
- The split let one real declaration hide behind another's entry. Keyed on
name alone, the two zero_specs produced byte-identical records, so 3022
declarations were covered by 3021 allowlist entries. Caught by the count
trailer. Every record now carries its originating module.
- The gate's success line said "single sanctioned axiom", inherited from the
accumulator's policy. This corpus permits NONE. A success message
describing a different rule is how an assertion stops meaning anything.
- selftest-axgate.sh lifted Phase 2b with a range ending at "Phase 3", so
inserting Phase 2c between them made it swallow the new phase and die on
variables only check.sh defines — surfacing as the BASELINE case failing,
a self-test blaming a gate for its own extraction bug. Both self-tests now
stop at the next phase marker whatever it is called, and refuse to run if
they capture more than one phase. The guard is the fix; the range was the
symptom.
WHAT THIS IS NOT, recorded in TRUSTED-BASE.md at the same length as the claim:
- No independent cone walker. The accumulator cross-checks collectAxioms
against a hand-written walker. Ported here it was wrong in BOTH directions
on mathlib's inductive shapes: EdPoint gave [] against the kernel's three
axioms, and once extended, ProjPoint gave three against the kernel's none.
Two implementations disagreeing both ways are a second wrong answer, not a
check. These cones rest on collectAxioms alone.
- Thirteen Proofs/Scalar* modules are inventoried by nothing — the
second-button seam, still open. Phase 2c names every uncovered module on
every run so the omission is visible rather than inferred.
selftest-inventory.sh exercises the shipping gate with six cases, each
asserting a specific diagnostic, including the one that matters: a cone
widened by one oracle while name, module and kind stay put. Negative-tested by
disabling the gate's diff, which turns two cases red including one for the
wrong reason, correctly reported as such.
Verified green: 20 runs across the four repositories (four buttons, four
harness, four inventory, four axgate, four binding self-tests), zero red. The
four check-scalar.sh greens from the preceding sweep stand: that script neither
reads the pin file nor changed.

verification: pin the harness, the audit drivers and the policy files (P1-c)
Every gate this repository has was executed by scripts that nothing pinned.
Round-5 review of the companion SLH-DSA repository stubbed the compiler
wrapper alone and its button printed ALL GREEN in 3.6 seconds over
deliberately destroyed proofs; flipping two guards in the audit driver
disabled every check with the digest byte-identical. Depth of checking is
worth nothing if the thing doing the checking is unbound — and every gate
added this week made that gap more valuable to an attacker, not less.
Phase 0c requires every harness file to match HARNESS.sha256. Two design
points carry the weight:
- WHICH files must be pinned is POLICY and lives in check.sh, never in the
map being consulted. If the required set were read from the pin file,
deleting an entry would silently un-pin that file. It is instead derived
from the filesystem, so a deleted entry is a set mismatch and a build
failure. That is the exact defect SLH-DSA round-6 found, closed here by
construction.
- Membership self-derives from the executable bit: anything this script can
shell out to must be pinned, so a NEW script fails closed until someone
pins it deliberately. Load-bearing files that are not executable — the
audit driver, the committed manifests, the policy tables — cannot be
discovered that way and are listed explicitly.
lean-guard is inside the set, which finally makes the standing "lean-guard
stays hash-pinned" rule a property of the repository rather than a convention.
selftest-harness.sh replays five cases, each asserting a specific diagnostic:
an edited lean-guard, a new unpinned executable, a deleted pin entry, a
missing pin file, and a positive control. It was itself negative-tested — with
the hash comparison removed it goes red on exactly that case while cheerfully
reporting "10 harness files match their pins".
TRUSTED-BASE.md states the limit at equal length to the claim: pinning a
harness from inside that harness is circular, and an author who edits a script
and refreshes its pin in the same commit passes every phase. What the pin
changes is that the edit can no longer be SILENT — it must appear in the diff
at the commit being reviewed. A green button says "this is the apparatus that
was reviewed", never "this apparatus is trustworthy".
Also fixed, found by this sweep: both self-tests compared the working tree
against its starting state with `diff <(echo "$VAR") <(command)`, which is
asymmetric — for a clean tree the variable is empty and `echo` emits a blank
line the command does not. It reported a difference precisely when nothing was
wrong, and only surfaced once P1-a was committed and Proofs/ became clean.
Both now compare as strings.
Verified green: 20 runs across the four ed25519 repositories (four buttons,
four harness self-tests, four axiom-gate self-tests, four binding self-tests,
four scalar buttons), zero red.

verification: pin the whole declaration surface (P1-b)
Phase 2b asks the kernel whether any AXIOM is declared under Proofs/. Phase 3
pins the cones of the named certificates. Between them sat every other
declaration in the corpus — around three thousand of them — and a helper lemma
quietly acquiring a hash oracle in its cone moved nothing either phase looked
at.
Phase 2c closes that. Ported from ltl-accumulator-verified, where a nine-attack
self-test proved a source-regex enumerator evadable by attributed, private,
indented and `instance` declarations and by a nested-namespace basename
collision. Reading the compiled environment sees what the kernel saw; no name
shape hides. Every constant contributes module, name, kind and full axiom cone,
and the observed set must equal inventory-allowlist.txt exactly in BOTH
directions, with a count trailer so a truncated run cannot pass as an empty
diff.
