 ## Result contract
 
-Write the full result through the channel chosen by the caller:
+Use the channel selected by the caller.
+
+For a short message, return only the evidence and decision needed next. For a
+file channel, write the detailed result to REPORT and return status, counters,
+and `REPORT: <absolute path>`.
+
+When relevant, the detailed result contains:
 
 - `STATUS: complete | questions | blocked`
-- `EVIDENCE:` changed files, executed commands, and final counters
-- `DECISIONS:` only questions for the coordinator or partner
-- `FINDINGS:` severity, location, essence, and verification method
+- `EVIDENCE:` changed files, checks, and observed results
+- `DECISIONS:` design or scope questions with options, costs, and a recommendation
+- `FINDINGS:` severity, location, claim, 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.
+Omit empty sections and raw tool output. Do not duplicate a file report in the
+final message.
