Re-derive the API 37 carrier counts, and correct what #226 left behind

The 2026-09-06 re-check of the instrumented suite. Every drifted line it found
came from #226, the last PR of the e2e read's own wave.

The suite is 70 tests in 14 classes, 6 carrying @FailsOnEmulatorApi37, gating
leg 64. The committed baseline says 6 and the advisory job agrees. Four places
still said five carriers of 69:

  - CLAUDE.md, three sites
  - FailsOnEmulatorApi37.kt's KDoc
  - two comments in status_check.yml

The gating figure is what hid it. 69 - 5 and 70 - 6 are both 64, so the one
number a reader checks against a run had not moved -- which is exactly why
CLAUDE.md says to derive these rather than remember them.

Two KDoc claims in SafPickerRoundTripTest described a draft rather than the
code. The save test says MP3 was chosen so the setup could not depend on device
codecs; the code converts at the default MP4_H265/FAST, which routes on
canEncode(H265). The negation of the stated reason was true. That is E1 and E3's
failure mode committed by the wave that found it, so it is written down as such
rather than quietly corrected.

Neither picker test has ever reported on the advisory leg. The marker's KDoc
said the picker test fails there behind the rotation test; with six carriers the
rotation test truncates the run first, and both advisory runs since #226 --
34042397320 and 34043502322 -- report expected: 6, received: 4, the four being
the three Media3 tests plus the rotation. The save test is therefore marked by
inheritance, not measurement, and both KDocs now say so.

FixtureDocumentsProvider.deletedDocumentIds() has no callers: #226 proved D4's
premise and drove only the success path, so deletePartialOutput against a real
DocumentsProvider is still asserted nowhere. Filed as #250 with the forcing
condition and the mutation; the accessor is kept with a KDoc naming that ticket
rather than removed and re-added.
