Round 4 reviewed round 3's commit. Nothing in production behaviour was wrong; what was wrong
was the round's own test and its comments, which is the failure class this loop keeps
finding.
- The new NavigationProvider case named after the `&& !channelViewRef.current` clause never
reached it. With storage cleared and a bare URL the provider lands on "home" (E24's own
default), not "feed", so asking for "feed" was an ordinary page change and the guard's
first conjunct short-circuited. Deleting the clause left all 828 tests green — a dead nav
control (the rail's own module stops closing an open channel page) with no red anywhere.
The test now asserts the precondition and calls `setPage` with the page that IS current.
- Both new Home cases rejected a promise and then asserted after one fixed macrotask.
React-query notifies through `notifyManager`'s own `setTimeout(0)`, registered after any
timer the test schedules, so the assertion raced it; two reviewers measured intermittent
reds. They poll for a signal that the rejection LANDED instead — the reroll button
releasing, which is also the honest one for the empty-answer case, where the empty state is
already on screen while the press is in flight and asserting it early would pass either way.
- `buryUnder`'s comment still opened with "one rule for both entry points" ten lines above the
paragraph saying the rule is complete only for one of them, listed the non-reporting palette
rows without `openChannel` — which has its own `replaceState` no-push branch and is reached
from PlayerModal too — and pointed at a ROADMAP.md this repository does not contain.
- `history.dom.test.ts`'s header claimed its layers close by genuine Backs only, which two of
its own tests contradict; and `CommandPalette.ordering.dom.test.tsx` still claimed to be
"the only assertion in the suite" doing what the file corrected in round 3 also does. Round
3's message said that pair was handled and only one side had been.
The provider test was re-mutation-checked (dropping the clause now goes red), and both
hardened Home tests still go red against their own reverts. Seven consecutive full runs green.
Gate: ruff, ruff format, 3x tsc, eslint (0 errors), prettier, knip, vitest 828, pytest 1005.
