Round 3 reviewed the round-2 commit across six dimensions. Fifteen findings, five survived
three adversarial refuters each; three died on 2+ refutations (a keyboard-focus claim that
is a property of `ui/Button` at all six of its `loading` call sites, a contract-test
false-pass that needs a deliberate revert plus a self-incriminating comment, and a
MAX_EXCLUDE coupling whose slice is unreachable from the real client).
- `rerolling` was still wrong for a FAILED press. `data === undefined` is true forever for a
key whose request failed (`retry: false`), so the next unrelated mutation re-disabled the
reroll button — the same defect round 2 reported, one branch over. `!isFetched` is the
flag that remembers a key settled; `!isError` would not have worked, because query-core
resets a data-less query to "pending" for the duration of a refetch, hiding the error
exactly when it matters.
- The hero fallback used `??`, which cannot tell "this budget's last pick resolved to NO
hero" from "nothing remembered". So a press that failed after an empty one resurrected the
card the page had already excluded as seen and just said it had nothing beyond. The tagged
slot is now authoritative for its own budget.
- `setPage`'s boolean — the input the whole burial rule reads — was asserted by nothing.
The type fences the SHAPE, so deleting a `return` fails tsc, but swapping the two values
passed typecheck and all 822 tests. NavigationProvider gets its first render test, on the
value AND on the effects the early return skips.
- `closeThenNavigate`'s door into `buryUnder` was equally unpinned: reverting that one call
site to the old unconditional burial left the suite green. It has the mirror case now.
- The comment claiming one rule serves both entry points was overstated. `buryUnder` fails
OPEN, and `CommandItem.run` is typed `() => void`, so only the palette's bare
`() => setPage(page)` rows forward the boolean at all. Nothing regressed — that path buried
unconditionally before — but the prose said more than the code does, so it now says what is
true and points at the deferred fix. Same for a "the only assertion in the suite" claim
that the file it cites as precedent also makes.
Every new test mutation-checked red for the right reason, both edges where there are two.
