Docs CI / lint-and-preview (push) Has been cancelled
Add new features and tests for AirGap and Time modules
- 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.

# Concelier LNM Cache Plan (Sprint 110)
Purpose: finalize structured caching fields now that Link-Not-Merge (LNM) schema is frozen (2025-11-17) and Evidence Locker contract is published.
## Cache payload shape
- Source: `advisory_linksets` collection (see `docs/modules/concelier/link-not-merge-schema.md`).
- Cache entry key: `{tenant}:{advisoryId}:{source}`.
- Cached fields (deterministic order):
- `observations` (ObjectId list, already sorted by source, advisoryId, fetchedAt)
- `normalized.purls`, `normalized.versions`, `normalized.ranges`, `normalized.severities`
- `conflicts` array (field, reason, values)
- `provenance.observationHashes`
- `builtByJobId`, `createdAt`
- Exclude mutable/derived fields; cache is rebuilt on ingestion replay, not updated in place.
## Storage & eviction
- Collection: `advisory_linkset_cache` (per-tenant index `{tenantId:1, advisoryId:1, source:1}` unique).
- Eviction: TTL on `createdAt` disabled by default; cache is replaced when a newer `provenance.observationHashes` differs.
- Determinism: cache documents written via canonical JSON writer (sorted keys); timestamps UTC.
## API exposure
- WebService: surface cached linksets via existing `/v1/lnm/linksets/{advisoryId}?source=...` (read-through); if cache miss, rebuild synchronously and store.
- Console: may rely on this cache for Advisory AI surfaces; no new payload fields required.
## Telemetry
- Meter `StellaOps.Concelier.Linksets` (existing) to add counters: `lnm.cache.write_total{result}`, `lnm.cache.hit_total{source}`; histogram `lnm.cache.rebuild_ms` for synchronous rebuilds. (To be wired in subsequent sprint.)
## Alignment
- Schema source of truth: `docs/modules/concelier/link-not-merge-schema.md` (frozen v1).
- Evidence Locker contract: `docs/modules/evidence-locker/attestation-contract.md` informs provenance fields; no shape changes required.
## Ownership
- Concelier Core + WebService guilds.
