{"body":"## Filbert review: row 177 round 2 (#1675), approve\n\nRequest 29350. Candidate manifest `3251f94d9e7e2a23e3e3e3ca5afc9b802bfce694ed3e400be31db96d5f185854` on base `c49de08e8` (candidate commit e097915d9). This re-reviews my round 1 changes verdict (29347).\n\n**Verdict: approve.** F1, F2 and F3 are fixed. No new findings. N1, N2 and the tester `talk --thread` row stay follow-ups, as BUILD.md lists.\n\n### What I ran\n\n- Built `~/filbert-scratch/r177-r2/wt`: `c49de08e8`, then `git apply --index build.patch`.\n  - `sha256sum -c` on the manifest: 16/16 OK, and the manifest file hashes to `3251f94d...5f185854`.\n  - The cached diff's patch-id `15f9c7bba807` equals that of `git diff c49de08e8 e097915d9`.\n- Base drift: `git log c49de08e8..refactor` (c0d6bc7d5) on the 16 paths is empty.\n- `git diff 1971683e1 e097915d9`: 4 files, +50/-7, the four BUILD.md names (bus README, broker.mjs, tester-threads.test.mjs, tester-writes.test.mjs). The other 12 paths are what I reviewed and ran in round 1.\n- Tests, one file at a time, TMPDIR `~/fs177`, slot grant sage-1168 after my /proc CLEAR: bus tester-threads 11, tester-writes 8, tester 14, messaging 13. 46/46 pass, 0 fail, 0 skip, every rc 0 (03:13:16Z-03:13:23Z), awk sums over the spec logs. The webui and cli files are unchanged since round 1, when I ran them (66/66).\n- My round 1 probe, unchanged except that it catches the refusal: the tester-thread run's gated `task.create` raise now prints `REFUSED tester-thread-human`, `DECISIONS 0`, and the human's `inbox` is `[]` before and after. In round 1 the same probe stored a decision routed to the human.\n- My own M15: deleted the `if (route === 'human' && this.#testerThread(s)) fail('tester-thread-human');` line (broker.mjs:1676). tester-threads exited rc 1, failing only T8a (\"a tester-thread run never raises a decision to the human; a human-thread run still does\"). Restored; the tree was back to the 16 staged paths.\n- Dewey's M1-M15, bus 447/447, webui 257/258 (1 skip), conversation 182/182, cli 396/396 and the ten scripts (340/0) are their receipts, not mine.\n\n### F1\n\n- broker.mjs:623-627 `#testerThread(s)` is the round 1 inline test, unchanged in meaning (`!!s.thread` for `s.thread`), and message.send now calls it (:1858).\n- broker.mjs:1676 refuses when `route === 'human'`, right after :1673 computes `route`. That covers an uncited gated raise, a hard wait, and an arbitrated raise whose arbiter is the raiser. It runs before the messaging check, the supersede withdrawal insert (:1686) and the decision insert (:1696), so a refusal stores nothing (T8a checks `decisions` is 0).\n- A raise routed to the chief stays allowed (T8b, `route_to 'chief'`, human inbox `[]`). That's the chief reach the README already names.\n- BUILD.md's table of human-target inserts: the message inserts are at :999, :1806, :1894, :2377, :2518, :2565 and :2596, and the decision insert at :1696, as listed. I checked the review.request guard (:2005, `a.to` must be a key of `b.roles`) and the arbiter check (:256). I didn't re-derive every row's reachability argument; the ones I read hold.\n- README :614 now says the run's `decision.raise` refuses the same way and a raise routed to the chief stays allowed. Deviation 7 records that DESIGN.md:82-84 was wrong.\n\n### F2 and F3\n\n- F2: the dispatch comment (:1300-1302) names `name.set`, `project.create` and the five row 177 verbs, and says each write records `tester`. Accurate: `thread.messages` is the one read among them.\n- F3: tester-writes.test.mjs:3 points to tester-threads.test.mjs for the thread verbs, and :60 says \"each of the six reads\", matching the six-entry READS.\n\n### Pins and readers\n\nNo 64-hex pin in packages/*/tests or scripts/test-*.sh names the four changed files, and no test reads packages/bus/README.md (the same grep as round 1, unchanged paths).\n"}
