Follow-up to #1589 (landed 17ad6f35). These are Darkwing's notes N1-N3 from comment 27953 on #1589:

  • N1: a toggle-on regression hangs browser-edge.test.mjs at its await boardRequested instead of failing it, which stalls the webui suite.
  • N2: test 2 in board-held.test.mjs claims no further request on the poll, but it never reaches the 10 s poll, so mutants 13 and 27 survive.
  • N3: the webui README's test paragraph lists three redirected requests. The test redirects six.

Brief: docs/plans/2026-10-12_pm-test-fixes.md, "Row 95 follow-up: Board tests fail fast, README lists every redirect". Tests and README only. Reviewer: Darkwing. Waits on row 77, which also edits the webui README.

Row 97 round 1 review (Darkwing): changes, one item

Candidate: candidate-manifest.sha256 from agents/researcher/work/queue-97/ (81c2906c), digest bdeca38dc8897b711b68f055cf346fc0ba6c04721e22720906c6b8fddc97902a. I applied build.patch (sha256 22150cee…) with git apply --index to a detached worktree of 3bd3f85c, and the manifest checks 3/3 OK. Nothing under packages/webui/src/ changes.

What I checked against the code

  • N1. The race in browser-edge.test.mjs rejects after 5 s with the named message, the finally clears the timer, and the outer finally closes the held responses, browser and servers. It answers the stall from the row 95 review.
  • N2. The stub's 10000 ms filter matches the two poll sites and nothing else: app.js:346 setTimeout(refresh, 10000) and bus.js:659 setTimeout(() => render(false), 10000). The other setTimeout calls use other delays (app.js:444 none, bus.js:767 2600, bus.js:875 none). The forced Pause click in test 2 is needed for the reason the build notes give: bus.js:875 defers schedule(), and only the resume reaches it with paused() false.
  • Mutant 14 is equivalent. api() (app.js:303) throws signedOut() when out() before any fetch, so the guard in refresh() (app.js:349) changes nothing observable.
  • N3. The README's six requests match the six redirect paths in test 2, and its poll and 5 s claims match the tests.

What I ran (2026-10-12T23:55:03Z to 23:56:46Z, my worktree, sequential, after a busy check, in the slot Sage cleared)

  • webui node --test tests/: 101 pass, 0 fail, 0 skipped.
  • Researcher's mutants.py with one mutant added, TMPDIR mine, 120 s per run:
mutant result
13 schedule polls with the toggle off killed (7.2 s)
27 bus schedule polls signed out killed (4.9 s)
12 refresh reads with the toggle off killed (6.8 s)
14 refresh without its signed-out guard ALIVE, equivalent
26 bus render without its signed-out guard killed (5.1 s)
13 under an arrow refactor (mine) ALIVE (9.2 s)
19 toggle on reads nothing killed (6.1 s)

Sources were restored byte for byte, and no process with a cwd in my worktree was left.

The change I'm asking for

The stub sorts a 10 s timer by its callback's name: f.name === 'refresh' ? 'board' : 'bus' (board-held.test.mjs:43). Test 1 then asserts boardPolls() === 0 three times (lines 112, 116, 139). Nothing in either test checks that a board poll is ever recorded. So if app.js:346 becomes setTimeout(() => refresh(), 10000), the shape bus.js:659 already uses, every board timer is filed as 'bus' and those three assertions pass whatever the page does. My added mutant is that refactor plus mutant 13 (if (!paused && !out()) timer = setTimeout(() => refresh(), 10000);), and it survives. The same edit without mutant 13 would also pass, so the guard can go vacuous without any test failing to say so.

One positive control closes it. In test 1, after the toggle is turned on (after the wait(SESSIONS) at line 120), wait for a board timer, for example await wait("window.__polls.includes('board')"). A refactor that changes the callback then fails there instead of disarming the assertions. I haven't run this line; my slot had ended.

Notes, none blocking

  • Six added lines run past 100 characters, the longest 192. The base files already had 32 and 39 such lines, so this matches them.
  • The README's wrapped paragraph has a short line, "again. Since the held roles lead the Board,". A reflow would fix it.
