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.

# Bundle Catalog & Items Repositories (prep for AIRGAP-IMP-57-001)
|
|
|
|
## Scope
|
|
- Deterministic storage for offline bundle metadata with tenant isolation (RLS) and stable ordering.
|
|
- Ready for Mongo-backed implementation while providing in-memory deterministic reference behavior.
|
|
|
|
## Schema (logical)
|
|
- `bundle_catalog`:
|
|
- `tenant_id` (string, PK part, RLS partition)
|
|
- `bundle_id` (string, PK part)
|
|
- `digest` (hex string)
|
|
- `imported_at_utc` (datetime)
|
|
- `content_paths` (array of strings, sorted ordinal)
|
|
- `bundle_items`:
|
|
- `tenant_id` (string, PK part, RLS partition)
|
|
- `bundle_id` (string, PK part)
|
|
- `path` (string, PK part)
|
|
- `digest` (hex string)
|
|
- `size_bytes` (long)
|
|
|
|
## Implementation delivered (2025-11-20)
|
|
- In-memory repositories enforcing tenant isolation and deterministic ordering:
|
|
- `InMemoryBundleCatalogRepository` (upsert + list ordered by `bundle_id`).
|
|
- `InMemoryBundleItemRepository` (bulk upsert + list ordered by `path`).
|
|
- Models: `BundleCatalogEntry`, `BundleItem`.
|
|
- Tests cover upsert overwrite semantics, tenant isolation, and deterministic ordering (`tests/AirGap/StellaOps.AirGap.Importer.Tests/InMemoryBundleRepositoriesTests.cs`).
|
|
|
|
## Migration notes (for Mongo/SQL backends)
|
|
- Create compound unique indexes on (`tenant_id`, `bundle_id`) for catalog; (`tenant_id`, `bundle_id`, `path`) for items.
|
|
- Enforce RLS by always scoping queries to `tenant_id` and validating it at repository boundary (as done in in-memory reference impl).
|
|
- Keep paths lowercased or use ordinal comparisons to avoid locale drift; sort before persistence to preserve determinism.
|
|
|
|
## Next steps
|
|
- Implement Mongo-backed repositories mirroring the deterministic behavior and indexes above.
|
|
- Wire repositories into importer service/CLI once storage provider is selected.
