feat(P8): IHF Phase 8 complete — Federated Hub Maturity
Implements the final phase of the IHF v0.1 specification:
- WidgetOwnership: delegated ownership registry (local/delegated/global),
append-only audit artefacts, ownership badge on widget show page
- HubRoutingRule + RoutingEngine: priority-ordered inter-hub routing engine;
null-inclusive category/widget-type matching; RouteNowAction for manual
re-evaluation; RoutedCandidates view per hub
- FederatedPolicyOverlay: draft → active → retired lifecycle; activated
overlays are immutable (same pattern as Phase 6 contracts); policy
compliance dashboard with decision coverage metrics
- StewardshipRole: named governance roles per hub; point-in-time revocation
pattern; hub and ops-board integration
- ArchiveRecord + is_archived: soft-delete on widgets; lineage inspector
traces full traceability chain (Widget → Events → Annotations → Candidates
→ Requirements → Decisions → Deployments → Signals + ArchiveRecord)
- FederatedGovernanceDashboard: 5-panel autoRefresh org-wide governance view
(ownership coverage, routing activity, policy compliance, stewardship
coverage, archive activity)
Schema: widget_ownerships, hub_routing_rules, federated_policy_overlays,
stewardship_roles, archive_records; ALTER widgets ADD is_archived;
ALTER requirement_candidates ADD routed_to_hub_id
Migration: 1743638400-ihf-phase8-federated-hub-maturity.sql
Tests: Phase 8 integration tests appended to Test/Integration.hs
Docs: docs/phase8-summary.md; SCOPE.md updated to Phase 8 complete
