+# Time Anchor Verification Gap (AIRGAP-TIME-57-001 follow-up)
+
+## Status (2025-11-20)
+- Parser: Roughtime verifier now checks Ed25519 signature; RFC3161 verifier uses SignedCms signature validation and signing time attribute. Still needs final trust root bundle + fixture alignment.
+- Staleness: calculator + budgets landed; loader accepts hex fixtures.
+- Verification: pipeline (`TimeVerificationService`) active; awaiting guild-provided trust roots (format + key IDs) for production readiness and to update tests/fixtures.
+
+## What’s missing
+- Roughtime parser: parse signed responses, extract `timestamp`, `radius`, `verifier` public key; verify signature.
+- RFC3161 parser: decode ASN.1 TimeStampToken, verify signer chain against provided trust roots, extract nonce/ts.
+- Trust roots: final format (JWK vs PEM) and key IDs to align with `TrustRootConfig`/Time service.
+
+## Proposed plan
+1) Receive finalized token format + trust-root bundle from Time Guild.
+2) Implement format-specific verifiers with validating tests using provided fixtures.
+3) Expose `/api/v1/time/status` returning anchor metadata + staleness; wire telemetry counters/alerts per sealed diagnostics doc.
