Docs CI / lint-and-preview (push) Has been cancelled
- Introduced `SbomService` tasks documentation. - Updated `StellaOps.sln` to include new projects: `StellaOps.AirGap.Time` and `StellaOps.AirGap.Importer`. - Added unit tests for `BundleImportPlanner`, `DsseVerifier`, `ImportValidator`, and other components in the `StellaOps.AirGap.Importer.Tests` namespace. - Implemented `InMemoryBundleRepositories` for testing bundle catalog and item repositories. - Created `MerkleRootCalculator`, `RootRotationPolicy`, and `TufMetadataValidator` tests. - Developed `StalenessCalculator` and `TimeAnchorLoader` tests in the `StellaOps.AirGap.Time.Tests` namespace. - Added `fetch-sbomservice-deps.sh` script for offline dependency fetching.

# Time Anchor Verification Gap (AIRGAP-TIME-57-001 follow-up)
|
||
|
||
## Status (2025-11-20)
|
||
- Parser: stubbed for Roughtime/RFC3161 with deterministic digest + derived anchor time.
|
||
- Staleness: calculator + budgets landed; loader accepts hex fixtures.
|
||
- Verification: pipeline exists (`TimeVerificationService`) with stub verifiers; still needs real crypto using guild-provided trust roots.
|
||
|
||
## 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.
|
||
|
||
## Owners
|
||
- AirGap Time Guild (format decision + trust roots)
|
||
- AirGap Importer Guild (bundle delivery of anchors)
|
||
- Observability Guild (telemetry wiring)
