The public history carried kat/__pycache__/mlkem768_reference.cpython-314.pyc, a compiled Python artifact embedding the operator's absolute local path. Text secret scanners do not read compiled binaries, which is exactly how it slipped through, and removing it from the tip would have left it reachable through the old root commits. So this repository is republished from a single clean root. This root also carries, from the previously unpublished line of work: - corrected LICENSE year, LICENSING.md, VERIFY-POLICY.md, and CITATIONS-UNRESOLVED.md remeasured 2026-08-11 (101 paths, README aligned) - O-018: run_consensus_verification.py ran 19 of 29 models and reported PASS; it now runs all 29, and computemarket_smt.py gains resolveByTimeout / reclaimUnsettled cases plus a negative control - O-006: the word 'audited' removed from next to Bouncy Castle, twice, after a concurrent edit resurrected it - O-014: prior art named and dated - Algorand's native falcon_verify shipped about ten months before AERE's precompiles; the primacy claim is withdrawn where it was implied - bench/ scripts parametrized so they actually run for an outsider (the earlier textual sanitization left $STAGING unexpanded inside Python strings) - AIP-2/AIP-3 errata with measured figures, spec remeasurements at 2026-08-01, and the spec-zk-stack retractions (owner is an operational key, not the Foundation; 'maximally sound' withdrawn; aggregator V1 deprecated) The redacted bench-host environment files from the sanitized line are kept exactly as published; the unredacted local variants are not carried.

# Test harness for the MMCS (Mixed Matrix Commitment Scheme) sub-component (port spec section 4,
|
|
# component (c)). Runs:
|
|
# 1. self-consistency: commit to each matrix batch, open EVERY valid leaf index, and confirm the
|
|
# authentication path recomputes the committed root; confirm a tampered proof / opening fails,
|
|
# 2. structural invariants: digest = 8 field elements; proof length = log2_ceil(max_height);
|
|
# openings are the rows at the reduced index in original matrix order,
|
|
# 3. cross-language agreement: Python vs Node vs Java produce byte-identical roots, openings, proofs,
|
|
# and primitive hash/compress outputs on a shared case set (three independent implementations),
|
|
# 4. CONFORMANCE: the root, openings, and proof reproduce real known-answer vectors emitted by
|
|
# executing the pinned p3-merkle-tree / p3-symmetric / p3-commit 0.4.3-succinct crates (via the
|
|
# ground-truth extractor), and verify_batch accepts the emitted openings and rejects tampered ones.
|
|
# Writes ../results/kat-results-mmcs-babybear.json and exits non-zero on any failure.
|
|
#
|
|
# ============================ HONEST SCOPE (CONFIRMED 2026-07-19) ============================
|
|
# This validates the MMCS construction LOGIC AND its conformance to Plonky3. The construction is the
|
|
# exact SP1 inner config (PaddingFreeSponge<Perm,16,8,8> hasher, TruncatedPermutation<Perm,2,8,16>
|
|
# compressor, FieldMerkleTreeMmcs<...,8>), verbatim from p3-merkle-tree's own mmcs.rs tests, over the
|
|
# CONFIRMED Poseidon2-BabyBear permutation. The "two wrong copies agree" trap is closed: the roots /
|
|
# openings / proofs reproduce real vectors extracted from the exact pinned crates (checksums matched),
|
|
# and the extractor's permute([0;16]) equals the confirmed Poseidon2 "zeros" vector, proving it uses
|
|
# the same permutation this reference does.
|
|
# What is still NOT validated: the FULL STARK verifier. The duplex-sponge challenger (f), the FRI
|
|
# folding/consistency arithmetic (d), and the SP1 recursion-AIR (e) are un-ported, so the top-level
|
|
# 0x0AE8 precompile stays fail-closed (returns EMPTY for every input) regardless of this component.
