GPT-5.6 live-site review + Fable live verification: - verify.py §4: was fail-OPEN — no openssl ⇒ signatures 'skipped' ⇒ still 'OK'. Now fail-CLOSED (exit 2 unless --structural-only, which is explicitly labelled a reduced check). --receipt was Merkle-path-only; now verifies the receipt's STH signature, key fingerprint, log_id, tree_size agreement, leaf_hash-vs-entry, and history membership before the inclusion proof. --all now also checks latest-sth == final history head and size == leaf count, and constant log_id. Adversarially tested: fail-closed exit 2; forged unsigned-root receipt REJECTED (was the 'inclusion VALID' hole); honest receipt + full run still exit 0. - README §8: I had written 'the first deployed transparency log to carry proofs of its own honesty' this session — an overclaim (the corpus proves properties of the accumulator MODEL, not operator honesty). Now: 'kernel-checked proofs about the accumulator model underlying its inclusion/consistency reasoning', 'first' softened to 'unaware of a precedent'.

# Lean Transparency Log — published mirror
|
|
|
|
This repository is the **git-published face** of a transparency log of
|
|
formal-verification attestations: signed statements that the Lean 4 proofs
|
|
of specific software, at specific git commits, re-check with exactly their
|
|
documented assumptions. Its first twelve leaves attest four cryptographic
|
|
Rust libraries (Ed25519 implementations); as of **entry 13 (2026-07-16)**
|
|
the log also attests **its own accumulator machinery** — a kernel-checked
|
|
mechanization of the log's security analysis, so the log carries
|
|
kernel-checked proofs *about the accumulator model* underlying its own
|
|
inclusion and consistency reasoning, as one of its own entries (subject
|
|
[`ltl-accumulator-verified`](https://github.com/saymrwulf/ltl-accumulator-verified);
|
|
scoped to the mechanized model — it does not prove operator honesty,
|
|
signing, or execution provenance). Current head: tree size 13, root
|
|
`3488a2d0…`.
|
|
|
|
Layout:
|
|
|
|
| Path | Content |
|
|
|---|---|
|
|
| `entries/NNNNNN.json` | one log leaf per file, append-only (git history mirrors log history) |
|
|
| `entries/<component>.attestation.json` | the newest attestation per library, for convenience |
|
|
| `receipts/<component>.receipt.json` | inclusion proof binding that attestation to the latest signed head |
|
|
| `sth-history.jsonl` | **every** Signed Tree Head ever issued — the witness channel: all cloners see the same heads |
|
|
| `latest-sth.json` | the current head |
|
|
| `provider.ed25519.pub` | the provider's public key (the sole trust anchor) |
|
|
| `verify.py` | standalone verifier, Python standard library only |
|
|
|
|
Verify everything locally, no installation:
|
|
|
|
```bash
|
|
python3 verify.py --all
|
|
python3 verify.py --receipt receipts/dalek-ed25519-verified.receipt.json
|
|
```

|
|
Honesty notes, always in force: attestations cover Rust **source** at a
|
|
pinned commit (clone it — the git hash is the content hash — and build it
|
|
yourself; compilers are declared trusted base). The log deliberately
|
|
retains early leaves recording a **failed** audit run: an append-only
|
|
trust ledger keeps its history. Tree heads are signed by the merkleized,
|
|
proof-attested Ed25519 library itself, and each signature embeds the
|
|
provider's own Merkle self-check of that library's leaf.
