+# M13-04F Status
+
+status: done  
+task: bounded and redacted server stdout/stderr  
+updated: 2026-08-19 America/New_York  
+enablingTask: false  
+parityStateChange: false
+
+## Scope
+
+Server job output is normalized through a production receipt before publication. Credentials, bearer/basic
+tokens, secret headers and Unix/Windows/file URL paths are replaced; UTF-8 output is truncated at fixed
+stdout/stderr byte budgets with an explicit marker. The receipt records original/emitted bytes, redaction
+count and truncation state. Server execution remains `DISABLED`; process cancellation and result publication
+are separate tasks.
+
+## Evidence
+
+- `npm --prefix web run test:server-job-output-redaction` passed 3/3 unit tests and the independent checker.
+- Checker output: `server-job-output-ok stdoutTruncated=1 stderrTruncated=1 redactions=6 totalBounded=1 execution=DISABLED next=M13-04G`.
+- `git diff --check` passed.

+## Next Task
+
+`M13-04G`: cancel Blender process tree and clean the one-shot directory.
+
+## Rollback
+
+Remove the output receipt protocol, unit/checker, report, manifest, package command and this status entry;
+restore `M13-04E` as the queue tail.
