- Archive the completed observability-service-registry SDD change into openspec/changes/archive/ (delivered across 5 slices; only jellyfin-service-registry remains active). - Stop ignoring .pi-map.md / .pi-map.index.md so the navigation maps are versioned alongside the code, and add the regenerated map pairs repo-wide.
