# Dual-run flags (RMGR-WP-0002)

State Hub remains the MCP/REST entrypoint. When flags are on, **checkout
mutation** is executed by Repo Manager.

## Environment variables

| Variable | Meaning |
| --- | --- |
| `RM_WRITEBACK=1` | Task file writeback via `rmgr update-task-status` |
| `RM_RECONCILE=1` | `fix-consistency` also runs `rmgr reconcile` for pilots |
| `RM_PILOT_REPOS=repo-manager` | Comma-separated slugs; **unset** = all repos when flags on |
| `RM_METER_PATH` | JSONL meter path (default `~/.repo-manager/mutation-meter.jsonl`) |
| `REPO_MANAGER_SRC` | Optional path to `repo-manager/src` for SH adapter |
| `RMGR_BIN` | Optional override command prefix for `rmgr` |

## Rollback

```bash
unset RM_WRITEBACK RM_RECONCILE RM_PILOT_REPOS
# or
export RM_WRITEBACK=0 RM_RECONCILE=0
```

State Hub immediately uses native C-15 writeback again.

## Pilot (repo-manager)

```bash
export RM_WRITEBACK=1
export RM_RECONCILE=1
export RM_PILOT_REPOS=repo-manager
export REPO_MANAGER_SRC=$HOME/repo-manager/src

# From API host environment, PATCH a task or:
cd ~/repo-manager
rmgr update-task-status --path . --task-id <canonical-or-uuid> --status progress

cd ~/repo-manager && statehub fix-consistency
rmgr dual-run-status
```

## Meter

```bash
rmgr dual-run-status
# or
wc -l ~/.repo-manager/mutation-meter.jsonl
grep repo-manager ~/.repo-manager/mutation-meter.jsonl | tail
```
