Closes four round-7/8 findings. Certified by the round-12 sweep: five repositories, both buttons and every self-test, 48/48 GREEN. ── `scalar-statements-unbound` (gpt, round 7, CRITICAL) ──────────────────── The main button bound its 31 certificates' elaborated statements and reachable specification bodies. This button bound NONE of its thirteen, while TRUSTED-BASE item 8 said the audit covers "every certificate" — false across the 44-certificate surface. The finding was raised in round 7, lost from the round-8 work list by an F-number collision between two reviewers, and re-raised in round 8. Proofs/ScalarAudit.lean is generated from each fork's OWN Audit.lean, so the canonicalisation is provably the same code: pp.all rendering, whitespace normalisation, transitive specification closure. check-scalar.sh Phase 3c pins the block's digest, requires the committed copy to match byte-for-byte so a mismatch can be DIFFED, and cross-checks the auditor's certificate set against the button's CERTS array. dalek ecf3a3f8 · anza 0d942e47 · risc0 4b550a61 · betrusted 4b550a61 risc0 and betrusted share a digest and that is correct, not a collision: their ScalarSubSpec.lean differs only in doc prose and in `black_box` entries inside `simp only [...]` lists AFTER `:= by`. Proof scripts. They bind the same statements over the same specifications, which is the documented scope. selftest-scalar-statements.sh ships the two attacks the reviewer asked for: ok gutted statement caught (cone unchanged) ok rewritten specification body caught (name and cone unchanged) The second rewrites a reachable reference body to `id (…)` — DEFINITIONALLY EQUAL, so the corpus compiles and every proof typechecks and the cone is byte-identical. Every earlier phase is blind to it. ── `drv-surface-no-cones` + `accounting-certifies-enumeration` (claude) ──── The round-7 accounting identity proved every kernel constant was ENUMERATED. The reviewer showed enumeration is not audit: their planted claim WAS enumerated, as DRV|LTLAccAudit.bait.smuggled|theorem with a real cone, and nothing examined it — rows had no cone, no allowlist covered them, the statement digest does not reach instruments, and Phase 2b gates DECLARED AXIOMS, a different question. "Progress of one step, not two." DRV rows now carry their axiom cone and are pinned in driver-allowlist.txt by inventory_gate.sh with a DRV tag — the same implementation that pins the corpus, in both directions, because a second copy of a coverage gate is a second thing to drift. The axiom policy is per-surface and enforced per surface: the corpus admits exactly the sanctioned boundary, the instruments admit none, and an instrument axiom fails EVEN WHEN ALLOWLISTED. Verified with the reviewer's own payload, both placements: before the walk -> UNCLASSIFIED: DRV|…|bait.smuggled|theorem|Classical.choice,Quot.sound,propext after the walk -> ACCOUNTING FAILED names it (kernel-side) ── `drv-naming-heuristic` (claude, round 7) ──────────────────────────────── Retired as load-bearing rather than patched. The rule admits a theorem whose name extends a constant declared alongside it, and "breaks in one line" — declare `def bait`, then `theorem bait.smuggled` walks through. It stays as a fast readable first check; membership in a committed allowlist is what now carries the weight, and a new row fails closed whatever it is called. ── what round 11 caught, which was mine ─────────────────────────────────── DRV rows first shipped WITHOUT their originating driver. dalek and anza run two drivers, each declaring its own `corpus`; keyed on name alone those two distinct declarations produced one byte-identical row, `sort -u` collapsed them, and the trailers summed to 37 against 36. The estate had already learned this on the corpus walk — INV rows carry their module because two modules both declare CurveFieldProofs.zero_spec — and I rebuilt the record without it. Rows now carry their driver, and the gate FAILS CLOSED ON DUPLICATE RECORDS naming the collision: two declarations sharing one entry means one is covered by the other's, which is exactly how a real declaration hides. The trailer now checks what the drivers EMITTED, not what survives de-duplication — conflating "the run was truncated" with "two rows were identical" is what let a record-format defect present itself as an arithmetic complaint.

Lean 4 mechanization of the security analysis (§6) of the system
report "The Lean Transparency Log" (archived at
https://ltl.zkdefi.org/paper/v0.2 — the version this corpus was built
against; the current paper, "Accountable Distribution of Machine-Checked
Correctness Evidence" at https://ltl.zkdefi.org/paper, presents these
results in its §5 and carries this corpus as entry 13): the Merkle
accumulator's own correctness and soundness theorems, kernel-checked, in
the same discipline as the four *-ed25519-verified subject corpora.
Status: ATTESTED — LTL entry 13, live (2026-07-16)
This corpus is now itself a leaf of the log it describes. It was appended
as entry 13 of the Lean Transparency Log (freeze 172a1d0), so the
log carries kernel-checked proofs about the accumulator model
underlying its own inclusion and consistency reasoning (a deployment we
are unaware of a precedent for; scoped to the mechanized model, not the
deployed verifier — see below). Live head after the append:
tree size 13, root
3488a2d0ff9f00415bb561d61b01a420e3ca2e0f7b29351ec9ebb3f57319da0d; this
corpus is leaf index 12, hash
8cb258d657f1fd00baaa9e0091e26c316cb69b591cb249a9543f51cade57c50a. The
old 12-leaf head (bcd15f9d…) is a proven prefix; the 12→13 consistency
transition is accepted by both the deployed verifier and the mechanized
model. Fetch and verify it at
ltl.zkdefi.org/v1/sth. The leaf carries
its own scope block: what is kernel-checked is the mechanized model
(§6), and correspondence to the deployed verifier is scoped by
KNOWN-GAPS 14/15 — the leaf does not claim the deployed verifier is
formally verified.
All paper-§6/§10 mechanization targets (v0.2 numbering) are
kernel-checked; the audit
surface is defined and green (verification/check.sh, exit 0). See
STATEMENT-MAP.md for the paper↔Lean review surface and
KNOWN-GAPS.md for the honest scope ledger.
Reviewed across six external adversarial rounds (GPT-5.6 + a second
Claude; zero broken theorems in any round; both approved). The audit
surface is an environment-derived inventory (Proofs/Inventory.lean +
pinned allowlist — 222 constants, 61 human-reviewed cones, self-tested by
selftest_audit.sh); the review kit is push-button reproducible
(run_bare.sh, self-contained fidelity target);
acceptIncl/acceptCons_sound route the theorems through the named
acceptance predicates; fidelity = agreement over pinned families
(230,271 + 230,016 baseline; 73,573 lied-size boundary cases with
3,867 expected one-sided divergences — KNOWN-GAPS gaps 14/15, not
extensional equality). Doc counts are asserted by check.sh Phase 3c.
How the append was done — release tuple, preflight, candidate-inspection
gate, and the 12→13 structural rehearsal — is recorded in
ATTESTATION-RUNBOOK.md.

| L6b | Theorem 3 (consistency soundness): consRecBinding (steps 1–2) + extractCons/extractCons_correct (+ _paper at the paper's exact quantifiers; acceptCons_sound routes it through the named acceptCons predicate, size bound derived from acceptance via consRec_some_le) |

Discipline (identical to the subject corpora)
verification/Proofs/contains ZEROaxiomdeclarations; the single sanctioned axiom site isverification/gen/— here, one opaque function: SHA-256. The theorems are constructive collision extractors, so collision resistance is never assumed, only interpreted.verification/check.shis THE button: compiles every file throughlean-guard(memory cap, core pinning, timeout, single-flight lock) and axiom-audits every certificate against its documented exact cone.- Reviewers without the operator toolchain:
verification/run_bare.shcompiles, axiom-audits, and inventory-gates the corpus with a plain publiclean(version pinned inverification/lean-toolchain); the operator path is overridable viaAENEAS_ENV. - Expected boundary:
propext, Classical.choice, Quot.soundplusLTLAcc.sha256for hash-touching certificates — documented per certificate incheck.sh, audited both directions.
The finished certificates are destined for the LTL itself as attestation leaves: the log carrying kernel-checked proofs of its own machinery.
