Confirmed, happy to be on it. Same string as my ERC-8312 entry so an editor reads the two as one contributor.

Applied — welcome aboard, and thanks for the exact ERC-8312-matching string. All four authors now confirmed on the line.

…larification Assets: swap cutoff_enforce.py to the v1 enforcer (baseline activation + tri-state evidence) and flip the single pre-baseline case in the cutoff, rotation and revocation vectors from REJECT to ADMIT (anchored_before_cutoff) — a pre-baseline artifact is back catalogue and admits classical-only rather than being retroactively invalidated. All three suites reproduce (8/8, 7/7, 6/6). Spec: qualify verification step 3 and Backwards Compatibility so a revocation ends authority even for a pre-cutoff artifact (revocation overrides the cutoff; signed off in the revocation lane, recompute-kit#16). Add a Related Work paragraph (Lean Consensus PQ validator registry: cryptographic expiry from statefulness vs explicit anchored authority-termination). Surfaced by zexoverz's review; conformance mirrored in trustless-ai/recompute-kit#16 (merged).

ERC-8373: Post-Quantum Anchored Key-Binding
Migrates the signature layer of on-chain / agent identity to post-quantum via an anchored classical-to-PQ key-binding and a consumer-enforced anchor-time cutoff — deliberately not a second signature (a forger who derives the classical key simply omits an optional extra signature; under this ERC, post-cutoff omission fails closed).
Discussion: https://ethereum-magicians.org/t/post-quantum-migration-for-on-chain-identity-an-anchored-key-binding-a-cutoff-verified-by-recompute-not-a-second-signature/29225
Reference implementations (production): two independent implementations under two NIST families (ML-DSA-65 / FIPS 204 and SLH-DSA-SHA2-192s / FIPS 205) converge on byte-compatible content-addresses; the SLH-DSA lane is mainnet-anchored with a live cutoff enforcer implementing the full verification procedure (in-force resolution, rotation, revocation). Conformance vectors for the binding, cutoff, rotation, revocation, and recovery classes are included under
assets/erc-8373/with executable checkers (stdlib Python).Authorship: all four authors confirmed.
