Self-review of the previous commit, on the same class it fixes.
"none of them asserts a mutation outcome", written about the 58 lines the
proposal-3 scan returns, is false. Two do: the mutation table at
`docs/decisions/records/ffmpeg/watermark-resolution-unified.md` line 104, which
names a dropped discriminator and the single test that catches it, and
`web/src/screens/AutoTuneScreen.test.tsx` line 174, which says what a revert to
the old flex row can redden. Both read in full at `efadbec29` rather than from
the truncated grep line - the truncation is how the first pass missed them.
Three kinds of sentence under one pattern is a better argument than the one the
false claim was making: it is not that the pattern finds only rationale, it is
that it finds rationale, state anchors and mutation-outcome claims side by side
and nothing in the string tells them apart.
Two smaller ones in the same commit. The new test's docstring said the gate is
"the one gate the others cannot cover" and the manifest said "the one PRE-FLIGHT
refusal a red proof cannot be told apart from" - both assert uniqueness among
the pre-flight refusals that neither measured, and a clause occurring zero times
also leaves the text identical. Narrowed to what the mutant demonstrates: no
later gate stands in for it. And the fixture comment glossed `verify_claim`'s
GREEN refusal in quote marks, which under this record's own proposal-2 clause
reads as a quotation of the library; it is not one, so the marks are gone.
