  "notes": "Larry's default reply is 3 to 8 sentences, longer only when asked (references/personality/voice-dna.md, agents/larry-extended.md line 41). The beta.77 QA report saw replies of 15 to 25 sentences. The Stop observer logs one row per over-length, non-exempt turn through checkReplyLength in lib/hmi/larry-reply-checks.cjs, in shadow mode only; the row holds the sentence count and the limit, never reply text. A reply to an explicit request for a list, a plan or the full answer is exempt. Measured on the 98-row voice corpus at plan time: 9 rows exceed 8 sentences. The rung stays declared: promotion is a human edit after a reviewed window of evidence. This reuses the existing voice observer instead of minting a second one (Canon Part 7)."
