+- Row 239 also re-pins `channel-proof.test.mjs`:
+  - `packages/webui/src/bus.mjs`, to 1eba9774…e5cf. That is the pin both rows change.
+  - `packages/cli/src/transport.mjs`, which is 239 only.
+  - `packages/bus/src/human.mjs` is a 252-only pin.
+- The two rows also share source files: `bus/src/broker.mjs`, `bus/src/runtime.mjs`, `webui/src/bus.mjs` and `webui/src/serve.mjs`.
+- Whichever row lands second rebases onto the first and recomputes the webui `bus.mjs` pin from the merged file. Both header comments are kept. It then reruns every touched test file whole.
+- Mos needs to see that re-pin (re-pins need Mos).

 ## Mutant plan (design section 6, J1-J17)
 
 Each mutant is one edit to the named source. Run the killing test, then restore and compare the sha256 against the pre-mutant hash with `git status` clean apart from the build. Kill rules are written before the runs.
