# /ar:stop — end the run Halt cleanly, leaving everything recoverable. ## Steps 1. Read state (`cat ./.ar/ar.jsonl | tail -50`). No `ar.jsonl` means no run to stop — say so and stop. 2. If `HEAD` carries a `Result: pending` trailer, an iteration was interrupted mid-measurement. Leave the commit alone, and record it in the sentinel's `reason` so a later `/ar:resume` re-measures rather than reverting it. 3. Append the sentinel — the last line of the file, and what `ar-loop.sh` greps for: ```json { "run": <n>, "status": "stopped", "segment": <s>, "reason": "<why>" } ``` 4. Write `./.ar/final_report.md` (see the `/ar:report` skill for its shape). 5. Print the final status block, the best commit, and — as text, not as a command to run — how to get back: ``` git switch <config.originBranch> # return to where the run started git log --format='%h %s' --grep='"status":"keep"' <config.branch> ``` ## Hard rules 1. **Destroy nothing.** No reverts, no branch deletion, no `git clean`. Stopping is not discarding: the experiment branch and every kept commit stay exactly as they are, and the operator decides later what to merge or bin. 2. **Do not switch branches.** Print the command and leave the experiment branch checked out for inspection. 3. Stopping is reversible — a later `/ar:resume` opens a new segment and carries on from the same state. Say so. ## Completion status End with a terminal status token as the last l
