Zero Slop 2.7.3

The adversarial four-way audit (Zero Slop vs no-ai-slop vs humanizer vs avoid-ai-writing, three audit lenses, superset verdict) completed with all eight agents and returned FALSE by exactly two findings — both execution misses on checks the skill already carries.

What changed

• The quoted-example exemption now covers only the quoted words. The authored frame around a quotation — the label introducing it, emphasis on that label, the list geometry it sits in — stays in scope for every check. Previously a line was skipped whole if part of it was quoted, which hid bold label-periods from check 69.
• Check 17 (Weasel attribution) now names the unnamed-validator variant: "an external checker", "a third-party audit", "an independent review" — name the tool or the auditor, or flag it.
• Both misses are must-flag fixtures (label-period-list.md, unnamed-validator.md), so register.py --recall keeps them caught. A fresh-eyes reading pass verified both fire correctly with the exemption properly scoped.
• The README fixes its own instances: plain colon labels replace the bold label-period list format, and the external checker is named as the AIStoryHub checker.

Scorer hash unchanged (99217fff…); pinned measurement records are relabeled, not remeasured. 240 tests, register gate clean, recall 16/16.
