`bash CHECK-quill-draft-compliance (the artifact gate).` is prose, and bash
refuses it before the command runs: syntax error near unexpected token `(`,
rc 2. tools/check_lint.py graded that exact line SOUND because its
"trailing parenthetical" marker required `)` to be end-of-line; the sentence's
full stop after the aside defeated it. The marker now allows `[.!?,;:]?`
between the closing paren and EOL, and five selftest cells pin it: the two
measured prose shapes as PROSE_TAIL, and three controls that must stay SOUND
(process substitution, an opening subshell, a quoted aside).
The pin moves 37 -> 42 in tools/selftest_baseline.tsv, in this diff.
Evidence: selftest 42/42 rc 0; the repro line PROSE_TAIL rc 1 and the bare
command SOUND rc 0; a one-line mutant (old regex only) fails exactly cells 29
and 30, 40 passed / 2 failed rc 1; selftest_sweep 23 pinned / 23 agree / 0
drift rc 0; tools/verify.py --fast 12 legs, 11 pass, 0 fault, 1 skipped, rc 0.
