## Result

`RESULT: PASS`

1. Formatter and source wiring passed: 4 tests, 19 assertions.
2. The complete `agent-node` production bundle built successfully.
3. Self, own-prefix, cooldown, and low-value skip diagnostics identify sender, reason, complete task ID, routing-layer disposition, and acknowledgement without accepting message content.
4. Witnessed-red mutation: downgrading the call from `log` to `debug` made the INFO-level wiring contract fail with `rc=1`.
5. Witnessed-red mutation: truncating the task ID to eight characters made the formatter contract fail with `rc=1`.
6. Restoring the source returned all tests to green.

## Scope

Observability only. Inbox filtering, acknowledgement, model delivery, persistence, Hub behavior, and production processes are unchanged.
