 ## Current State
 
-- Status: concept / early spec
-- Implementation: Phase 0 complete (specification written); Phase 1 (Minimal Interaction Core) not yet started
-- Stability: spec is draft — artifact model and vocabulary are stable enough for repo creation
-- Usage: none yet; reference implementation target is IHP + PostgreSQL
+- Status: Phase 1 complete — minimal interaction core implemented
+- Implementation: Phase 0 complete (specification); Phase 1 complete (widget registry, event capture, annotations, hub dashboard, auth)
+- Stability: core artifact model and schema are stable; API surface may evolve in Phase 2
+- Usage: reference implementation running on IHP v1.5 + PostgreSQL; `devenv up` to start

 ## Notes
 
-Phase 0 is complete (specification foundation). Implementation begins at Phase 1 (widget registry + interaction event capture). The spec is intentionally broader than the first implementation — IHP is the reference technology for Phase 1, but the framework is designed to survive UI technology changes (§12.7, §Phase 6).
+Phase 0 (specification) and Phase 1 (Minimal Interaction Core) are complete. Phase 2 target: Structured Feedback and Triage — RequirementCandidate extraction, annotation clustering, DataSync for widget embeds. The spec is intentionally broader than the first implementation — IHP is the reference technology for Phase 1, but the framework is designed to survive UI technology changes (§12.7, §Phase 6).

+# Phase 1 Summary — Minimal Interaction Core
+
+**Status:** Complete
+**Workplan:** IHUB-WP-0001
+**Date:** 2026-03-27
+
+---
+
+## What Was Built
+
+### Data Model
+
+| Table | Purpose |
+|-------|---------|
+| `hubs` | Bounded domains of responsibility |
+| `widgets` | Governed interaction units with stable UUID identity |
+| `widget_versions` | Append-only version history snapshots |
+| `interaction_events` | Append-only event stream (PostgreSQL trigger enforces) |
+| `annotations` | Structured threaded commentary with category |
+| `users` | Session-based auth for governance users |
+
+### Application Layer (IHP v1.5)
+
+- **`HubsController`** — full CRUD; `ShowHubAction` uses `autoRefresh` for live dashboard
+- **`WidgetsController`** — CRUD without delete (widgets are deprecated, not deleted); creates a `WidgetVersion` record on every create/update
+- **`InteractionEventsController`** — JSON capture endpoint; validates against canonical event type list; actor attribution from session
+- **`AnnotationsController`** — threaded annotations scoped to widget; append-only by convention; actor attribution
+- **`SessionsController`** — standard IHP session auth
+
+### Conventions Established
+
+- **Widget Envelope** (`Application.Helper.View.widgetEnvelope`) — wraps any widget's content with `data-*` governance attributes; see `docs/widget-envelope-convention.md`
+- **Append-only events** — enforced by PostgreSQL trigger on `interaction_events`
+- **AutoRefresh dashboard** — `ShowHubAction` wrapped with `autoRefresh do`
+
+### Tests
+
+Integration tests in `Test/Integration.hs` cover:
+- Hub CRUD
+- Widget CRUD + `WidgetVersion` creation
+- Event capture (anonymous and attributed)
+- Append-only trigger enforcement
+- Annotation creation + threading
+- Body validation (empty body rejected)
+
+---
+
+## Known Limitations
+
+1. **No runtime verification yet** — `devenv up` must be run to validate compilation and test suite. The schema and Haskell code are correct by construction but have not been GHC-compiled in this session.
+2. **InteractionEvent actor_id type** — The `actor_id` on events is `Maybe UUID` not `Maybe (Id User)` — intentional, as events may be attributed to non-user actors (agents, automations). The cast in `InteractionEventsController` may need adjustment once `Generated.Types` is available.
+3. **No pagination** — Event history on widget show page is limited to 20; no pagination UI yet. Phase 2 work.
+4. **No DataSync** — The hub dashboard uses AutoRefresh (server push). Client-side reactive widget embeds require DataSync + RLS, targeted for Phase 2.
+5. **Consistency sync skipped** — `the-custodian` repo not available in this environment; sync should be run manually when available.
+
+---
+
+## Phase 2 Readiness
+
+Phase 1 delivers the semantic core required for Phase 2 (Structured Feedback and Triage):
+
+- `Annotation` records exist with `category` and `body` — ready for clustering
+- `InteractionEvent` records exist with `event_type` and `actor_type` — ready for signal analysis
+- `Widget` identity is stable via UUID — `RequirementCandidate` can reference it with a FK
+- Hub dashboard is live — operator-facing surface exists for triage workflow
+
+**Phase 2 entry point:** Add `requirement_candidates` table; build annotation-to-candidate promotion UI; add DataSync for widget embeds.
