Task #14: show a full version timeline for each skill family, not just the
single most-similar prior scan.
What changed:
- OpenAPI spec (lib/api-spec/openapi.yaml): new GET /scans/{id}/lineage
(operationId getScanLineage) returning an array of ScanLineageEntry
(id, name, verdict, riskScore, relation, similarity, comparedScanId,
fingerprint, createdAt). Regenerated api-zod + api-client-react via codegen.
- API (artifacts/api-server/src/routes/scans.ts): new lineage endpoint.
Builds an undirected graph over all scans linked by the comparedScanId chain
AND identical (non-empty) fingerprints, then BFS-walks the connected
component containing the requested scan and returns it newest-first. Works
purely from existing data, no re-scanning. 404 for unknown ids.
- UI (artifacts/skillguard/src/pages/scan-report.tsx): new VersionTimeline
card rendering the family as a vertical timeline; each entry shows verdict,
relation badge, similarity, risk score and date. The viewed scan is marked
"Aktuell angezeigt"; every other entry links to the existing comparison view
/vergleich/{viewedId}/{entryId}. Card hidden when the family has <=1 member.
Notes:
- Lineage = connected component, so any member returns the full family.
- Verified end-to-end locally (created new/modified/identical chain, checked
lineage ordering + 404, confirmed timeline + compare links in the UI),
then deleted the test scans.
