+# Point-in-Time Vulnerability Query (As-Of Date)
+
+## Status
+NOT_FOUND
+
+## Description
+The ability to evaluate vulnerabilities against advisory data as of a specific historical date is not implemented. The replay system tracks inputs but does not provide temporal advisory queries.
+
+## Why Not Implemented
+- No temporal/as-of-date vulnerability query API found in `src/`
+- The Replay module (`src/__Libraries/StellaOps.Replay.Core/`) and Unknowns module (`src/Unknowns/`) track historical state but do not provide temporal advisory queries
+- The Unknowns persistence layer has SQL migrations with `point_in_time` references: `src/Unknowns/__Libraries/StellaOps.Unknowns.Persistence/Migrations/001_initial_schema.sql`
+- `IUnknownRepository` has methods that could support temporal queries
+- The Facet module has `FacetSeal` with point-in-time concepts: `src/__Libraries/StellaOps.Facet/FacetSeal.cs`
+- The Scanner has historical data in Smart Diff tables: `src/Scanner/__Libraries/StellaOps.Scanner.Storage/Postgres/Migrations/005_smart_diff_tables.sql`
+- Key rotation service tracks historical keys: `src/Signer/__Libraries/StellaOps.Signer.KeyManagement/IKeyRotationService.cs`
+- Infrastructure for temporal queries exists but no unified "as-of date" API endpoint has been built
