mrwulf 1bc4f39f35 round 7: assert pin-map completeness (NEW-13), correct the count to 137, fix the regeneration-scope contradiction 
The third reviewer demonstrated NEW-13: PROVENANCE.json is a tracked file that
nothing pins, and Phase 0's only completeness test was 'is the map non-empty'.
Deleting the harness_integrity_sha256 key therefore silently un-pinned BOTH
lean-guard and Proofs/Audit.lean with no diagnostic, after which the round-6
logic mutation ran to ALL GREEN over a repository proving False with the digest
byte-identical. Reproduced here before fixing. The required pin NAMES now live
hardcoded in check.sh — policy in the root of trust, values in the map — so a
shortened map is a build failure naming the missing entries. Self-test attack 18
performs the deletion.

GPT reviewer, independently: the documented '131 assertion points' was wrong.
Recounted from the code, the defensible figure is 137 mono-path evaluated cases
(9 retained original + 108 randomized + 10 NIST internal + 10 NIST
external-pure); 131 had folded in 3 deployed-only prehash cases while omitting
the retained test, and TRUSTED-BASE then decomposed it as 20 + 108 = 128,
contradicting itself. Item 9 now carries the full table, states that 127 of the
137 compare mono against deployed, keeps the 3 prehash cases explicitly outside
the total, and records that only two SHA2-512 and one SHAKE-256 vector are
executable there — so this is not NIST coverage of all four supported prehash
variants.

Also from GPT: PROVENANCE.json contradicted itself, saying extraction
'reproduces all four model files byte-identically' while its own _comment
correctly said the two *External files are hand-maintained. Extraction
regenerates two files; the other two are byte-pinned. Corrected.

TRUSTED-BASE item 11 now discloses that PROVENANCE.json is itself load-bearing
and unpinned, and item 7's stale snapshot head is fixed. README states the
lean-guard graceful fallback and that the empirical bridge runs on stable Rust
without any Lean toolchain (round-7 NEW-16), which is the first load-bearing
part of this work a third party can reproduce with cargo alone.

Recorded clean run — check.sh + independent cone dump

External review round 2 asked for a recorded clean run at the current pin by a party with the toolchain, so a reviewer who cannot run Lean has current evidence. Captured 2026-07-24. Pins are in PROVENANCE.json. The cone dump below is an independent collectAxioms read (not the asserted table in Proofs/Audit.lean); it matches each certificate's expected boundary.

Locked cargo run under the pinned nightly (round-3 reviewer recommendation)

The differential test mono_matches_deployed_verify is the sole verify_mono→deployed bridge; recorded here under --locked on the toolchain pinned by rust-toolchain.toml (nightly-2026-06-01, the transpiler's own channel). Note: the upstream integration-test files hardcode all twelve parameter sets, so they only build with default features — the single-feature run therefore uses --lib (which contains the differential test), and the full suite runs with default features. This explains the round-1 GPT observation that single-feature cargo test fails to compile: an upstream test-layout property, not a defect of the snapshot.

INDEPENDENT RUN — executed by the operator (the round-3 blocker)

Round 3's single remaining blocker was a recorded toolchain session executed by a party other than the author agent. The operator ran the block below personally on 2026-07-27 (a first attempt on 2026-07-24 failed with a memory-clamped lean abort on a loaded desktop — an environment condition, diagnosed from ~/.lean-guard.log and addressed by the lean-guard stderr-diagnostics commit 62d7ed1; the proofs were never implicated). Result: check.sh ALL GREEN at 62d7ed1 (11 certificates, exact-cone audit passed) and extract.sh regeneration byte-identical against fips205-source @ 797b4ef — both sha256 values match PROVENANCE.json. Transcript verbatim from the operator's shell:

Round-4 hardening (third reviewer, 2026-07-27)

The third reviewer demonstrated three fail-opens OUTSIDE the cone check (F1 unbound cert set / un-manifested theorem; F2 statements unbound; F3 model bytes unbound). All fixed. check.sh green with the hardened gate, and the adversarial self-test then rejected eight attacks including the two the reviewer used to make the button green over a repo proving False.

CORRECTION (2026-07-27, found by an independent audit of this file). The three lines that stood here inside the fence below were not console output: they were a hand-written summary of the run, fenced as if captured. check.sh never printed them. The author wrote them; that is fabricated evidence in the one document whose stated purpose is to carry machine evidence to reviewers who cannot run the toolchain, and it is exactly the failure this project exists to prevent. They have been removed. The selftest transcript that follows in the same fence is verbatim.

Two further corrections to this file's framing:

  • the "INDEPENDENT RUN — executed by the operator" block above is at proof repo 62d7ed1, which predates the round-4 gate (its transcript has no Phase 0). It is genuine and operator-executed, but it is not a run of the gate that now ships;
  • consequently, at the time of writing there was no recorded run of the current gate by an independent party. Any transcript below this line that is not explicitly attributed to a named party was produced by the author agent.

Rule adopted going forward: no text is placed inside a fence in this file unless it was captured with tee/cat from the real command, and every evidence block states its date, its pin, and who ran it.


check-selftest: attacking the gates
====================================
✓ attack 1 rejected (dead-file gate)
✓ attack 2 rejected (extra-axiom detection — evil_ax named)
✓ attack 3 rejected (missing-oracle detection — exact cone, not subset)
✓ attack 4 rejected (existence check — vanished cert cannot pass as 0-axiom)
✓ attack 5 rejected (module enumeration — an un-manifested False theorem cannot pass)
✓ attack 6 rejected (statement fingerprint — a gutted statement of the same cone cannot pass)
✓ attack 7 rejected (Phase 0 model-byte integrity — a hand-edited model cannot compile)
✓ attack 8 rejected (manifest fingerprint — a silently-dropped cert cannot pass)

SELFTEST GREEN: the gate rejects dead files, extra axioms, dropped oracles,
vanished certs, un-manifested False theorems, gutted statements, hand-edited
models, and deleted manifest rows.

SELFTEST GREEN: 16 attacks rejected + digest-coverage check — dead files, extra axioms, dropped
oracles, vanished certs, un-manifested False theorems AND defs, gutted
statements, hand-edited models, dropped manifest rows, widened policy,
specification folds redefined to the loop, a False-proof in the auditor,
a stubbed harness, and stray modules.

Round-7 fixes — author-agent run, 20260728T110335Z, proof repo @ (this commit)

Captured with tee. NOT independently executed — but note that the third reviewer DID independently run check.sh and check-selftest.sh to green at dce0473 and 1e50295 on its own hardware and toolchain build, and recomputed the audit digest outside check.sh. What remains author-attested-only is extract.sh's byte-identical regeneration, which no reviewer has observed.

PIN ROTATIONS: source 3153988 -> c945821 (test/vector only; all four model files verified byte-identical across it). No model or harness pin rotated.

NOTE (round-7 NEW-16): the entire empirical bridge runs on STABLE Rust — no Charon, Aeneas, OCaml or pinned nightly required. The nightly pin exists only to align charon cargo. A third party can reproduce all 137 bridge cases with cargo alone.

check-selftest: attacking the gates
====================================
✓ attack 1 rejected (dead-file gate)
✓ attack 2 rejected (extra-axiom detection — evil_ax named)
✓ attack 3 rejected (missing-oracle detection — exact cone, not subset)
✓ attack 4 rejected (existence check — a vanished cert cannot pass as 0-axiom)
✓ attack 5 rejected (enumeration — an un-manifested False theorem cannot pass)
✓ attack 6 rejected (statement check — a gutted statement of the same cone cannot pass)
✓ attack 7 rejected (Phase 0 model-byte integrity)
✓ attack 8 rejected (audit-manifest digest — a silently-dropped cert cannot pass)
✓ attack 9 rejected (digest covers allowedBoundary — the policy cannot be widened silently)
✓ attack 10 rejected (a specification fold cannot be silently redefined to the loop)
✓ attack 11 rejected (enumeration covers every declaration kind, not just theorems)
✓ attack 12 rejected (the auditor audits itself — no exemption)
✓ attack 13 rejected (Phase 0 pins lean-guard — the harness is in the TCB and bound)
✓ attack 14 rejected (no .lean may sit outside gen/ and Proofs/)
✓ attack 16 rejected (Phase 0 purges every .olean under verification/, so an
  orphan compiled module with no source cannot satisfy an import)
✓ attack 17 rejected (Phase 0 pins Audit.lean — its LOGIC cannot be silently switched off)
✓ attack 18 rejected (the pin map cannot be silently shortened — required names are in check.sh)
✓ check 15 passed (the hashed block carries all 12 reference-fold bodies,
  including the recursive _f companions and their extracted-primitive calls)
