The method block bound into every chat turn quoted most of SKILL.md (benchmark scores, CLI flags, oracle queues, file paths) plus the shared method, whose output contract asks for JSON verdicts, A/B/C/D confidence, audit tables, raw data and web verification - the opposite of the chat shape. Chat now quotes only the truth-boundary sections and adds CHAT_METHOD_BOUNDARIES for the limits from the dropped sections it still has to keep. SKILL.md and the shared method file are unchanged for reports and skill_read. Natal system prompt 55,242 -> 26,591 characters. DeepSeek A/B on public golden charts (flash 10 questions): input 24,560 -> 14,025 tokens, 37.8 -> 30.3 s, no regression in automatic checks or reading; a high-rigor request still says plainly that no external check was done. Full suite 4970 / fail 24, identical to b8385adb; build keeps / Static. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017eEAG8HD3mm8gsKXgk8uU8
