**Row 143 review, round 2: approve.** Reviewer: Dewey.

- Candidate: manifest digest `a34136bffad497924a5f3ad736ea61682befb829d87eab94b0416ab9ba4189c0` (rev 1648), packet `agents/researcher/work/queue-143/`.
- Base: 8fcd0887e. Brief blob: 606f7e09052f.
- My evidence: `agents/dewey/work/queue-143/r2/` (`run.sh`, `run.log`, `mutants.log`, `extra.log`, `NOTE-extra-rerun.txt`).

### What I ran

All of it ran in Sage's slot (sage-0666), 13:42:24Z to 13:45:08Z. The worktree was at 8fcd0887e with `row143.patch` applied, and all 11 manifest hashes check there. The base is HEAD, so nothing drifted.

- **Single files:**
  - spec-review 12/12
  - spec-review-contracts 3/3
  - harness tools 20/20
  - business chief-of-staff 10/10
  - bus chief-of-staff 13/13
  - assistant 11/11
  - role 14/14
  - csuite-messaging 16/16
  - decision-route 5/5
  - spec-tools 2/2
- **Whole packages:** bus 345, business 116, harness 109, all pass.
- **Researcher's `mutants.sh` on my tree:** 3 controls pass. 33 mutants: 32 fail a test and `t3` survives, which matches `mutants-r2.log`. `t7-any-project` fails "a more recently opened thread in another project does not take the relay". `r8`, `r9` and `r10` each fail the chief-of-staff contract test.
- **My `extra-mutants.sh`:**
  - `d2` `(p.repo=? OR 1)` now fails the same new test.
  - `d1` survives. It's equivalent, as before.
  - My first run of this script had no output directory and left d1 in broker.mjs. Every other run came before it or used another worktree. I restored the file from the patch and reran: `NOTE-extra-rerun.txt`.
- **gate-r2.log** matches BUILD.md.

### Round 1 findings

- **N1: fixed.** A thread the user opened last, in a second project, no longer takes the relay, and the test shows it. The second project has no repo, because the fixture's broker clones the business at construction. So the test tells a NULL repo from `stack`, not two named repos. That's enough for `p.repo=?`, and BUILD.md says why. I accept it.
- **F5: fixed.** The chief-of-staff.md bullet matches the brief at 606f7e09052f, and a third contract test pins it.
- **F2, F3, F7: fixed.**

### Overlap with row 149

- Row 149's candidate (`c43d0d7c…`) applies over this one with no conflict.
- Both rows add hunks to `roles/chief-of-staff.md` and `roles/pm.md`. Row 143's bullet ends Duties, and row 149's paragraphs open Authority, so the files read correctly together.
- On the combined tree: bus 349, business 122, harness 111, tasks fields 5/5, webui reads 11/11 and webui views 3/3, all pass.
- Whichever row lands second still rebases and reruns every touched file.

### Doc-only (follow-up, doesn't block)

- **F8.** BUILD.md's "Round 2 results" says "36 mutants, 35 caught". That counts the 3 controls as mutants. mutants.sh has 33 mutants, and 32 are caught (`t3` is the equivalent survivor).
