Record being wrong about which change broke a test

A UI test went red in the same run that adopted three new APIs. The one
touching that screen was reverted; the test still failed. A modifier
order was corrected; still failed. Simulator data was wiped; still
failed. Running it against a clean checkout — which should have been the
first move, not the fourth — it failed there too, with none of the work
present.

The scrolling entry had already been rewritten to explain the fault in
confident detail. That write-up was fiction, so it now says what actually
happened: the API was convicted on circumstance and remains unproven
here, and the one claim that survives is about its two-way binding
costing invalidations.

xcode-practice gets the general lesson, since it will outlive this
particular test: stash and rerun before reasoning about which edit did
it, and a note recording a false cause is worse than no note, because
the next person believes it.
