The header still called the essay a 'parked blog-post source' awaiting
entry 13, and two future tenses ('will carry') survived — the blog is
published and entry 13 is live. Caught by a fresh-pattern sweep after
the hand-picked patterns of the first documentation pass missed them.

Lean 4 mechanization of the security analysis (§6) of the paper
"The Lean Transparency Log" (https://ltl.zkdefi.org/paper): 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), making
the log the first deployed transparency log to carry kernel-checked
proofs of its own accumulator machinery. 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 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.
| layer | content | status |
|---|---|---|
| L1 | bytes, hleaf/hnode, domain separation (Lemma 1) | done (domsep: axiom-free) |
| L2 | MTH, Root, ConsRec definitions + termination | done (cones: propext, LTLAcc.sha256, Quot.sound) |
| L3 | inclusion completeness (Theorem 1) + named acceptance acceptIncl |
done (incl_complete: propext, Classical.choice, LTLAcc.sha256, Quot.sound) |
| L4 | frontier binding content (Lemma 2) | done as specializations — inlined in the extractor walk (extractIncl), whole-tree (extractMTH), ConsRec (consRecBinding); the standalone Root receipt-uniqueness instance was deleted with the vacuous root_binding in S3.5 and deliberately NOT restored (optional, unused — KNOWN-GAPS gap 3) |
| L5 | inclusion soundness = EXPLICIT extractor extractIncl (Theorem 2) |
done, non-vacuous |
| L6a | descent extractor extractMTH (Theorem 3 step 3 = Lemma 2, whole-tree instance) |
done, non-vacuous |
| 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) |
done, non-vacuous |
| L6c | pin-store state machine safety (Proposition 1): pinAccept_monotone, pin_prefix_correct, fork_distinct |
done, non-vacuous (per-step; multi-step chain = gap 7) |
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.
