# RMGR-WP-0002 completion evidence
**Date:** 2026-08-09
**Stage:** ArchitectureBlueprint Stage B (dual-run)
## Delivered
| Task | Result |
| --- | --- |
| T01 flags + meter | `src/repo_manager/dual_run.py`, `docs/dual-run.md` |
| T02 hardened command | idempotency, expected_head_sha, UUID match, optional push |
| T03 SH facade | `state-hub/api/services/repo_manager_dual_run.py` + PATCH `/tasks` hook |
| T04 reconcile proxy | `fix_repo` calls `rmgr reconcile` when `RM_RECONCILE` + pilot |
| T05 pilot | Fixture + SH facade call → `applied` + git_sha; meter lines |
| T06 package | this file + `wp0002-pilot.json` + `mutation-meter-pilot.jsonl` |
## Operator enable (pilot)
```bash
export RM_WRITEBACK=1
export RM_RECONCILE=1
export RM_PILOT_REPOS=repo-manager
# ensure SH can import/run rmgr:
export REPO_MANAGER_SRC=$HOME/repo-manager/src # optional; adapter defaults to ~/repo-manager/src
```
Restart State Hub API process so env is picked up for PATCH dual-run.
## Rollback
```bash
unset RM_WRITEBACK RM_RECONCILE RM_PILOT_REPOS
# restart SH API
```
## Tests
```bash
cd ~/repo-manager && pytest -q # includes test_dual_run.py
```
## STATE-WP-0079 handoff
Expand `RM_PILOT_REPOS` fleet-wide after meter shows RM writebacks healthy.
Meter path: `~/.repo-manager/mutation-meter.jsonl` (or `RM_METER_PATH`).
Strangler exit: zero `source=state-hub` checkout mutations for pilot set under load.
