History
StellaOps Bot 7792749bb4 feat: Add archived advisories and implement smart-diff as a core evidence primitive 
- Introduced new advisory documents for archived superseded advisories, including detailed descriptions of features already implemented or covered by existing sprints.
- Added "Smart-Diff as a Core Evidence Primitive" advisory outlining the treatment of SBOM diffs as first-class evidence objects, enhancing vulnerability verdicts with deterministic replayability.
- Created "Visual Diffs for Explainable Triage" advisory to improve user experience in understanding policy decisions and reachability changes through visual diffs.
- Implemented "Weighted Confidence for VEX Sources" advisory to rank conflicting vulnerability evidence based on freshness and confidence, facilitating better decision-making.
- Established a signer module charter detailing the mission, expectations, key components, and signing modes for cryptographic signing services in StellaOps.
- Consolidated overlapping concepts from triage UI, visual diffs, and risk budget visualization advisories into a unified specification for better clarity and implementation tracking.

Archived Superseded Advisories

Archived: 2025-12-26 Reason: Concepts already implemented or covered by existing sprints

Advisory Status

These advisories described features that are already substantially implemented in the codebase or covered by existing sprint files.

Advisory Status Superseded By
