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.
