### Troubleshooting
- If a row's example has placeholders, replace only the placeholder values and preserve separators.
- If a call fails, open its receipt and repair it with POST /api/dispatch {key, body, repairs:'inv_ID'}.
- If token scope denies this system, ask the owner for a row:/rows:/pfx: token scoped to the exact operation set.
