feat: scoped evidence and explicit attestation signatures v0.1#9
Merged
Conversation
Closes #6. Align evidence with the registry-facing vocabulary used by Modulora: publisher-identity, domain-verified, content-integrity, and install-parity (early owner-verified remains readable for v0 compatibility). Add structured subject and coverage so a scoped check cannot be widened into a generic badge; add optional expiry and require limitations for scans, builds, human review, and unassessed source. Make the signature boundary explicit: attestationDigest covers the canonical attestation statement excluding signature/transparencyLog; signature.payload must declare attestationDigest. releaseDigest alone only identifies artifact bytes. RFC 0002 specifies consumer behavior and digest independence. Fixtures cover domain subject enforcement, install-command parity coverage, human-review limitations, and wrong signed payloads. 32/32 tests pass.

What
Aligns evidence with Modulora's canonical registry-facing vocabulary, adds structured subject/coverage/expiry, tightens limitation requirements, and makes the attestation signature boundary explicit through attestationDigest + signature.payload.
Why
Closes #6. Evidence must remain scoped and limitation-aware; a release digest alone does not bind publisher authorization or the full attestation statement.
Compatibility
Testing
32/32 tests pass, including domain subject mismatch, install-parity command coverage, missing human-review limitations, generic verified rejection, and wrong signature payload.
