## Result contract

Write the full result through the channel chosen by the caller:

- `STATUS: complete | questions | blocked`
- `EVIDENCE:` changed files, executed commands, and final counters
- `DECISIONS:` only questions for the orchestrator or user
- `FINDINGS:` severity, location, essence, and verification method
- `NEXT:` one concrete action or `none`

Omit empty sections. Do not include raw output or a reasoning narrative. For a
file channel, put the full result in the named file and return only status,
counters, and `REPORT: <absolute path>`. For a message channel, return one
concise result without a report path.
