# 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
