+- **`gherkin-mutator` status lines may not appear until the run finishes.** A

 - **`mutate-file.sh` works from every component dir, including the DB.** It
   defaults `MUTATE4JS_BIN` to the client's installed
   `node_modules/mutate4javascript`, and the tool's `npm test` baseline runs in
   the current component, so the DB mutation runs use the DB suite without a
   second tool install.
 
+- **A killed `mutate4javascript` run can strip the embedded manifest.** If the
+  tool is killed after it removes the old `mutate4javascript-manifest` block but
+  before it rewrites it (seen on `topic-query.js` when a worker hung and the
+  shell timeout fired), `git diff` shows the whole manifest as deleted. Restore
+  it with the tool's own command from the component dir:
+  `<tool> <source-file> --update-manifest`. After any timeout, confirm every
+  mutated file still contains `mutate4javascript-manifest-begin` before

+- **Run `verify.sh` after committing the review changes, not before.** The
