+# Phase 01.1 — Validation Strategy
+
+> Per-phase validation contract for feedback sampling during execution.
+
+---
+
+## Test Infrastructure
+
+| Property | Value |
+|----------|-------|
+| **Framework** | `pytest 9.0.2` + `pytest-asyncio 1.3.0` |
+| **Config file** | `pyproject.toml` |
+| **Quick run command** | `pytest tests/adapter/matrix -v` |
+| **Full suite command** | `pytest tests/ -v` |
+| **Estimated runtime** | ~20 seconds |
+
+---
+
+## Sampling Rate
+
+- **After every task commit:** Run `pytest tests/adapter/matrix -v`
+- **After every plan wave:** Run `pytest tests/ -v`
+- **Before `$gsd-verify-work`:** Full suite must be green
+- **Max feedback latency:** 20 seconds
+
+---

+
+## Wave 0 Requirements
+
+- [ ] `tests/adapter/matrix/test_reconcile.py` — startup reconciliation scenarios, `next_chat_index`, and no-provisioning assertions
+- [ ] `tests/adapter/matrix/test_reset.py` — CLI reset modes, dry-run behavior, and operator guidance output
+- [ ] `tests/adapter/matrix/test_dispatcher.py` — startup bootstrap order and targeted unknown-room recovery coverage
+- [ ] Fake `AsyncClient` fixture surface for joined rooms, room state, leave, and forget behavior
+
+---
+
+## Manual-Only Verifications
+
+| Behavior | Requirement | Why Manual | Test Instructions |
+|----------|-------------|------------|-------------------|
+| Reconciled Space/chat rooms render correctly in a real Matrix client after restart | PH01.1-BOOT | Client UX and homeserver state cannot be fully trusted from fake nio fixtures | 1. Start the bot with existing Space/chat rooms. 2. Verify the bot does not create duplicate Space or chat rooms. 3. Send a command in a recovered room and confirm it routes normally. |
+| Server-side cleanup leaves the account in a usable Element state after `server-leave-forget` | PH01.1-RESET | Element/archive behavior and homeserver retention are client/server integration concerns | 1. Run `python -m adapter.matrix.reset --mode server-leave-forget --dry-run`. 2. Run without `--dry-run` on a test account. 3. Confirm joined rooms disappear for the bot and fresh invites can be accepted cleanly. |
+
+---
+
+## Validation Sign-Off
+
+- [ ] All tasks have `<automated>` verify or Wave 0 dependencies
+- [ ] Sampling continuity: no 3 consecutive tasks without automated verify
+- [ ] Wave 0 covers all MISSING references
+- [ ] No watch-mode flags
+- [ ] Feedback latency < 20s
+- [ ] `nyquist_compliant: true` set in frontmatter
