feat(P4): IHF Phase 4 complete — Outcome Observation and Antifragility Loop
Some checks failed
Test / test (push) Has been cancelled
Details

Browse Source 
Closes the IHF improvement loop. Full antifragility chain now traversable:
Widget → Annotation → Candidate → Requirement → Decision → Deployment → OutcomeSignal

New artifacts:
- DeploymentRecord (immutable, links DecisionRecord to a deployed version)
- OutcomeSignal (append-only; DB trigger prevents UPDATE/DELETE)
- ChangeEvaluation (one-per-deployment; UNIQUE constraint; 1–5 score)

New capabilities:
- DeploymentRecordsController (index, show, new, create)
- RecordOutcomeSignalAction — capture improved/regressed/neutral/inconclusive signals
- Pre/post comparison panel on deployment show (±30-day event/annotation counts)
- Regression detection — improved signal followed by high/critical annotation
- ChangeEvaluation — idempotent score+rationale per deployment
- Recurrence tracking — cycle count per widget, leaderboard
- AntifragilityDashboardAction (autoRefresh, 5 panels) per hub
- Phase 4 integration tests (T01–T08 logic coverage)
- docs/phase4-summary.md; SCOPE.md updated to Phase 4 complete

State Hub: workstream 07e9c860 → completed

## Current State
- Status: Phase 3 complete — governance and decision linkage implemented
- Implementation: Phase 0 complete (specification); Phase 1 complete (widget registry, event capture, annotations, hub dashboard, auth); Phase 2 complete (annotation severity, annotation threads, requirement candidates, triage lifecycle, reviewer assignment, triage dashboard); Phase 3 complete (requirement promotion, decision records, policy references, implementation change references, governance audit trail dashboard)
- Stability: core artifact model and schema are stable; Phase 3 data model (Requirement, DecisionRecord, PolicyReference, ImplementationChangeReference) is additive and stable
- Status: Phase 4 complete — outcome observation and antifragility loop implemented
- Implementation: Phase 0 complete (specification); Phase 1 complete (widget registry, event capture, annotations, hub dashboard, auth); Phase 2 complete (annotation severity, annotation threads, requirement candidates, triage lifecycle, reviewer assignment, triage dashboard); Phase 3 complete (requirement promotion, decision records, policy references, implementation change references, governance dashboard); Phase 4 complete (deployment records, outcome signals, pre/post comparison, regression detection, change evaluation, recurrence tracking, antifragility dashboard)
- Stability: core artifact model and schema are stable; Phase 4 data model (DeploymentRecord, OutcomeSignal, ChangeEvaluation) is additive and stable; outcome signals and interaction events are append-only (DB triggers)
- Usage: reference implementation running on IHP v1.5 + PostgreSQL; `devenv up` to start
