The chair-feedback chain was DEAD: 27 feedback rows captured, 0 ever became a lesson the writer reads (no weekly-analysis job ever existed). The chair's own corrections — the most authoritative signal of all, and exactly "learn from every returned draft" — went nowhere. decision_lessons can't carry them: it's FK-coupled to a style_corpus row (a signed final), which a case-in-progress doesn't have. So chair STYLE feedback instead rides the discussion_rules channel that already reaches the writer for all blocks — the same path /training promote uses. - db.append_global_rule: the locked read-modify-write append, extracted from web `_append_methodology_override` into one shared impl (G2). The web function is now a thin wrapper that seeds defaults; chair-feedback calls it directly. - record_chair_feedback (MCP tool): a STYLE-category correction (style/wrong_tone/ wrong_structure) with a lesson_extracted flows immediately to discussion_rules. The chair IS the gate — no separate approval (INV-LRN1 graduated gate). SUBSTANCE feedback (missing_content/factual_error/other) is case-specific → recorded only. Invariants: INV-LRN1 (chair-authored style = highest authority, flows; substance not auto-flowed), G2 (single append impl shared by promote + feedback), INV-LRN5 (style channel only).
