+# Advisory Ingestion with Canonical Deduplication
+
+## Module
+Concelier
+
+## Status
+VERIFIED
+
+## Description
+Advisory ingestion pipeline with canonical deduplication, linkset observation factory, and raw advisory processing.
+
+## Implementation Details
+- **Modules**: `src/Concelier/__Libraries/StellaOps.Concelier.Core/`, `src/Concelier/__Libraries/StellaOps.Concelier.Merge/`, `src/Concelier/__Libraries/StellaOps.Concelier.Persistence/`
+- **Key Classes**:
+  - `CanonicalAdvisoryService` (`src/Concelier/__Libraries/StellaOps.Concelier.Core/Canonical/CanonicalAdvisoryService.cs`) - core canonical advisory management
+  - `CachingCanonicalAdvisoryService` (`src/Concelier/__Libraries/StellaOps.Concelier.Core/Canonical/CachingCanonicalAdvisoryService.cs`) - caching decorator for canonical advisory lookups
+  - `MergeHashCalculator` (`src/Concelier/__Libraries/StellaOps.Concelier.Merge/Identity/MergeHashCalculator.cs`) - deterministic semantic merge hash for deduplication
+  - `ConnectorWorker` (`src/Concelier/__Libraries/StellaOps.Concelier.Core/Orchestration/ConnectorWorker.cs`) - orchestrates advisory ingestion cycles
+  - `AdvisoryRepository` (`src/Concelier/__Libraries/StellaOps.Concelier.Persistence/Postgres/Repositories/AdvisoryRepository.cs`) - raw advisory persistence
+  - `AdvisoryCanonicalRepository` (`src/Concelier/__Libraries/StellaOps.Concelier.Persistence/Postgres/Repositories/AdvisoryCanonicalRepository.cs`) - canonical advisory persistence
+  - `AdvisorySourceEdgeEntity` (`src/Concelier/__Libraries/StellaOps.Concelier.Persistence/Postgres/Models/AdvisorySourceEdgeEntity.cs`) - source-to-canonical edge tracking
+- **Interfaces**: `ICanonicalAdvisoryService`, `IMergeHashCalculator`, `IAdvisoryRepository`, `IAdvisoryCanonicalRepository`
+- **Source**: Feature matrix scan
+
+## E2E Test Plan
+- [ ] Ingest the same advisory from two different sources (e.g., NVD and GHSA) and verify they deduplicate to a single canonical advisory
+- [ ] Verify `MergeHashCalculator` produces identical hashes for semantically equivalent advisories from different sources
+- [ ] Verify `AdvisorySourceEdgeEntity` tracks both source edges pointing to the same canonical
+- [ ] Verify `CachingCanonicalAdvisoryService` returns cached results on repeated lookups
+- [ ] Verify new advisories with different CVE IDs produce distinct canonicals
