LLM Errata v0.4.1 is an integrity and conformance hardening release.
Highlights:
- immutable source-target and metadata-only release binding;
- append-only, bidirectional publication supersession chains;
- gate-specific G3–G5 structural validation separated from qualification;
- exact same-erratum G4 adapter-receipt and validator binding;
- complete three-system G5 experiment contract;
- byte-preserving shared G2 surface digest;
- fail-closed malformed evidence across G2–G6;
- full-width SHA-256 state roots and clearer snapshot limitations.
Validation: exact-head independent standards/spec reviews passed; Python 3.11 and 3.13 CI passed; 390 repository tests passed.
Production verdict remains NOT_PROD_READY. G2–G6 remain BLOCKED; this experimental release does not claim production readiness, external conformance, audited production cryptography, independent implementations, operated-system interoperability, or operational certification.
