JMR-devandClaude Opus 5 e81403c5f3 Measure the fourth claim rather than asserting it, and fix three slips
Review of the previous commit found three things of exactly the kind it corrects.

"Both of the advisory runs that exist" asserted exhaustiveness that had not been
checked -- two jobs were read, and the #248 branch had three status_check runs.
All four advisory runs at baseline 6 are now read: 34041156680, 34041593697,
34042397320 and 34043502322 each report expected: 6, received: 4, failed: 4,
and the only SAF test reporting in any of them is the rotation one. The claim
was right; the wording claimed more than the evidence.

CONVERSION_TIMEOUT_MS's KDoc said the bound is "two orders of magnitude" clear
of the real cost. 120 s against a measured 11.8 s is one.

status_check.yml dated the save test's marker to 2026-09-05. fa10d94 is dated
2026-09-06.

Also reworded that comment's summary: "two abort the framework and two never
report" double-counts the picker test, so a reader summing gets seven.

JMR-devandClaude Opus 5 54167c052f 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.
