+## Row 95 follow-up: Board tests fail fast, README lists every redirect
+
+### Problem
+
+Darkwing's review of row 95 (comment 27953, approve) left three notes,
+and row 95 landed in 17ad6f35 without a second round.
+
+- N1: `packages/webui/tests/browser-edge.test.mjs` awaits
+  `boardRequested` (line 29), which only the server's `/api/board`
+  handler resolves. If the "Show machine sessions" toggle stops reading
+  the board, the await never settles. The test is cancelled at 120 s,
+  its `finally` never closes the browser and server, and the file never
+  exits. `node --test` has no file timeout, so the webui suite stalls
+  instead of failing.
+- N2: test 2 in `board-held.test.mjs` claims no further request on the
+  poll, but it waits 600 ms and both polls are 10 s. Mutants 13 and 27
+  survive for that reason.
+- N3: the webui README's test paragraph says test 2 redirects three
+  reads. It redirects six: the board, `agents`, `/api/conversations`,
+  `/api/seen`, `/api/queue` and the send.
+
+### Owner and reviewer
+
+Owner: assigned on the row. Reviewer: Darkwing.
+
+### Files owned
+
+- `packages/webui/tests/browser-edge.test.mjs`,
+  `packages/webui/tests/board-held.test.mjs`, and any test helper they
+  share
+- `packages/webui/README.md`, the test paragraph only
+- `agents/<owner>/work/queue-<row>/`
+
+### What ships
+
+- N1: the toggle step in `browser-edge.test.mjs` fails within a few
+  seconds when no `/api/board` request comes, and the browser and
+  server close either way. Prove it with the toggle-on mutant: the file
+  exits nonzero inside 30 s, with no browser or node process left.
+- N2: either test 2 reaches a poll tick, by a shorter poll in the test
+  or a clock the test controls, and mutants 13 and 27 die; or the
+  test's comment and the README stop claiming the poll. The packet says
+  which, and why.
+- N3: the README's test paragraph names all six redirected requests.
+
+Suites: the webui and control-board node suites, and every
+`scripts/test-*.sh`.
+
+### Out of scope
+
+Any change under `packages/webui/src/`. Row 95's behavior stays as
+landed.
+
+### Gate
+
+Darkwing approves on the row's issue, naming the candidate manifest.
+The suites above pass on Sage's gate rerun. Tests and README only, so
+nothing goes live and no restart is involved.
