Conversation
…hain) Independent ASPICE/26262 + cybersecurity audits found real defects: - F2 (security fail-open): malformed issued-at silently disabled the staleness warning; now validated as RFC 3339 at parse, impossible dates rejected, one shared epoch_days validator - potency: mutants gate + strict policy now REQUIRED merge checks (REQ-MUTATE-001 was marked verified but bypassable) - honesty: README no longer claims "nothing implemented"; claim-check covers it; SECURITY.md added (disclosure + invariants + limits) - hazards: SH-005 (key compromise) + SH-006 (deposit-pipeline compromise) + SC-005/006 — the two the STPA-Sec seed missed - supply chain: Cargo.lock tracked, --locked builds, cargo-deny in CI, cross pinned, actions SHA-pinned, cosign identity regexp anchored Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_019TNtfRjLNhEz82G2ggeeNu
…ght them) The v0.12.1 F2 fix added length/dash-position and leap-rule guards; the now-required mutation gate flagged 9 survivors in them. Restructured epoch_days so each guard is independently reachable and added shape + full-Gregorian-leap kill tests. Zero survivors across the trust set.
