Record all six defects and the 9% baseline

Adds decision entries for the unpaired set-of-mark label, the interjection
verifier false positive, and the vision-blob clearing bug, plus the per-run
speaker audit script used to measure the chapter.

+**Closed.** `_set_of_mark` labels a detected face `unknown` when gated pairing
+(`decisions/audit-phase1.md#gated-face-pairing`) matched it to no present character. An answer pointing
+at such a mark identifies nobody, so it must not carry `som_face`, the highest-trust provenance.
+
+Evidence: all 7 `som_face` lines in the first 36 panels of the 2026-08-11 rerun had `speaker_ref` kind
+`unknown`. The label sat on lines with no speaker. Same defect class as the fake `tail`.

+**Closed.** `verify_script` must stay quiet on valid narration, because `run_stage_script` retries once
+and then raises (`decisions/audit-phase1.md#verifier-false-positives`).
+
+Evidence: the narrator wrote `"...Hm?"` for the source line `"Uh... hum...?"`. Both rules fired at once.
+`Hm` was absent from the source words, and a 6-character quote needs 5 matching characters to ground,
+so it got 4. That halted the `script` stage at 112/116 on job `778297bc`.
+
+Interjections join `_STOPWORDS`. A quote of three letters or fewer is no longer grounded-checked. That
+holds the same line as the dialogue prompt's 1-3 character noise rule. The stage then passed 116/116.
+
+Forbids: scoring a quote too short for the ratio to carry meaning.
