160 passed over the three affected files. Two guards this round introduced are
removed, each because it was measured and found unkillable, and one real cut is
added in their place.
The end-of-line anchor on the judge's clause expression: with the pointer-block
route and the asset-name tie already in place, the only case it covered is a
label forging a clause inside a block that also carries a real one -- which
`assets._inline` now makes unreachable from a document. Removed with `$` gone
the whole suite stays green, which is the measurement: a guard nothing can fell
is not a guard, and it would also have made the mutant below unfaithful.
The length check on a short absolute run in `_bmp_rle8_rows`: unobservable by
construction. A run shorter than its declared count means the stream ran out,
so the loop cannot reach an end-of-bitmap afterwards and the picture is refused
either way -- the partial paint is discarded with the frame.
A FIFTH CUT REPLACES THEM, and it makes an existing bound load-bearing: a
stream cut in the middle of a delta escape, 17 of 32 pixels wrong by this
file's own decoder. Without the two-byte bound in that branch the cut raises
IndexError instead of a coded refusal.
