- Implement `SbomVexOrderingDeterminismProperties` for testing component list and vulnerability metadata hash consistency.
- Create `UnicodeNormalizationDeterminismProperties` to validate NFC normalization and Unicode string handling.
- Add project file for `StellaOps.Testing.Determinism.Properties` with necessary dependencies.
- Introduce CI/CD template validation tests including YAML syntax checks and documentation content verification.
- Create validation script for CI/CD templates ensuring all required files and structures are present.
- Introduced new advisory documents for archived superseded advisories, including detailed descriptions of features already implemented or covered by existing sprints.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.
- Add RpmVersionComparer for RPM version comparison with epoch, version, and release handling.
- Introduce DebianVersion for parsing Debian EVR (Epoch:Version-Release) strings.
- Create ApkVersion for parsing Alpine APK version strings with suffix support.
- Define IVersionComparator interface for version comparison with proof-line generation.
- Implement VersionComparisonResult struct to encapsulate comparison results and proof lines.
- Add tests for Debian and RPM version comparers to ensure correct functionality and edge case handling.
- Create project files for the version comparison library and its tests.
