# Phase 07 Plan 05: Gap Closure — Startup Reconciliation + Verification Truth Update Summary

Lazy `_ensure_reconciled()` guard wired into `net_fault_list`; `reconcile()` now runs once per server lifetime on first async tool call. Both VERIFICATION.md gaps closed: FAULT-07/SC-6 (reconcile never called) and FAULT-02/SC-2 truth (all-tap netem design documented as intentional).

---

## Tasks Completed

### Task 1: Wire lazy startup reconciliation into net module (TDD)

**Files:** `vmcluster_mcp/net/__init__.py`, `tests/test_net_fault_list.py`

Added `_reconciled = False` module-level flag and `_ensure_reconciled()` async guard to `vmcluster_mcp/net/__init__.py`. The guard calls `await _registry.reconcile()` exactly once per server process lifetime, on the first invocation of `net_fault_list`. Three new TDD tests added and passing.

**Commits:**
- `8ad6f0b` — `test(07-05): add failing tests for lazy reconciliation in net_fault_list` (RED)
- `beab99c` — `feat(07-05): wire lazy startup reconciliation into net_fault_list` (GREEN)

### Task 2: Update VERIFICATION.md gap statuses

**File:** `.planning/phases/07-network-node-fault-injection/07-VERIFICATION.md`

Both gaps updated to `status: resolved`. Frontmatter `status` changed from `gaps_found` → `resolved`. Score updated to `6/6`. SC-6 table row updated to ✓ VERIFIED. Plan 07-01 and 07-03 must-have truth tables updated. Requirements FAULT-02 and FAULT-07 updated to ✓ SATISFIED.

**Commit:** `0215bbd` — `docs(07-05): resolve both gaps in 07-VERIFICATION.md`
