The build signs fixture artifacts and findings with ECDSA P-256 over canonical JSON (DER-encoded signature in a 'signature' field) \u2014 ES256 is a JWS algorithm, but the wire encoding is NOT a JWS compact serialization and fixture keys ship as PEM in a JWKS-shaped fixture file. No surface claims JWS (README/manifest say 'signed finding envelope'), so nothing is misrepresented; the mechanism the spec protects \u2014 asymmetric signing, offline verify with the public key only, tamper-evidence, findings key distinct from identity keys \u2014 is proven in C10. CONDITION: before any G-LIVE/interop phase, either emit true JWS or amend the spec; recorded as backlog B-CM-1.",
  "DEVIATION RULING 2 \u2014 verify_revocation_status gained an optional expected_epoch: ACCEPTED. Additive only; a divergence between the caller's expected epoch and the feed epoch is announced in the output (C11), which is the \u00a75/ch.13 staleness law applied to the caller, not a weakening of it.",
  "DEVIATION RULING 3 \u2014 the impostor fixture shares the honest card's body hash (artifact_hash excludes 'signature' by construction): ACCEPTED as fixture design. The signature is the discriminator and the bench proves it bench-side (C3: hashes recomputed equal, verdicts differ). Two consequences recorded as observations, not defects: (a) revocation lookup by artifact hash alone cannot distinguish honest from impostor \u2014 the feed entries also carry kid, and verdict revocation checks consult both; (b) supersede linkage is by body hash, so an impostor verdict supersedes the honest finding for the same body \u2014 honest rendering, since the BODY is the same claim and the findings differ only in their check lists, which is exactly what the envelope preserves.",

The convention is stated in code, never silent.",
  "OBSERVATION (non-failing): a wrong-typed field INSIDE an artifact object (e.g. expires_at as a dict, amount as a dict) does not refuse the call \u2014 it lands as a verdict whose structure check names the missing/invalid fields and whose state caps at UNRESOLVED. That is the ch.13 shape (artifact fields are untrusted data, \u00a75.1; the verdict is computed on structure), and C14 asserts it explicitly: never CONSISTENT, never a crash, the failed check is named in checks_performed.",
