## Rollback
Every modify is stamped with `--reviewer gemma4-e4b` (or whatever was
passed). To reverse a pass:
```bash
# Via SQL on the live DB
skraak sql --db ./db/skraak.duckdb \
  "UPDATE label SET certainty = 70 WHERE reviewer = 'gemma4-e4b' AND certainty = 91"
```

or re-run with the correct values to overwrite.
