chore(memory): LRN-081 + TODO reconcile — close ritual

LRN-081: Claude commit trailers only on Claude-COMPOSED content; a commit merely staging user-authored text gets none (staging != authorship). TODO reconcile: checked L26 'Cleanup machine courante' DONE (make plugin EXIT=0 this session ran Step 8.5, fs-verified strays absent); added (a) harden install-plugins.sh Step 1 npm-via-corepack (BLK-013 fix-forward) + (b) darwin re-baseline of the 5 ex-broken skills (BDR-043). Trailers present here because Claude composed the LRN + TODO formulations (LRN-081's own rule) — unlike e591510 which staged raw user text.

+## 2026-06-30 (cont.) — close ritual (LRN-081 + TODO reconcile) + gate-suspense gap caught
+- Ran /close (capitalize --ritual). After a fresh capitalize → registries propose near-nothing (BLK-013/BDR-043 already this session); live work = TODO reconcile + 1 LRN.
+- GAP caught: the prior STEP-3 gate (LRN-081 + TODO check L26 + 2 adds) had stayed UNRESOLVED — conversation diverted to an out-of-band /reconcile + EVAL-013 (`437697e`, author user, NOT Claude) which never touched the gate items. Verified absent, then completed. Exactly the declared-vs-real drift /reconcile exists to catch.
+- LRN-081: Claude commit trailers only on Claude-COMPOSED content; staging user-authored text gets none (staging ≠ authorship). Born of `e591510` (clean) vs `5b03ac2` (trailers).
+- TODO: checked L26 "Cleanup machine courante" DONE (`make plugin` EXIT=0 this session ran Step 8.5; fs-verified both strays absent — closes the session's opening "cleanup ligne 26"); added (a) harden install-plugins.sh Step 1 npm-via-corepack ([[BLK-013]] fix-forward); added (b) darwin re-baseline of the 5 ex-broken skills ([[BDR-043]], promoted from its action-field).

 - **pattern**: the --help chantier (implement [[BDR-001]] as a global CLAUDE.md instruction "on --help → render help + stop") was KILLED by its behavioral RED. Before writing a line, measured the control (6 reps, `/web-validate` + `/harden`, no instruction): **6/6 already rendered rich help AND stopped without dispatching** — the supposedly-absent behavior was fully present. Residual value = format consistency across 6 divergent shapes → not worth ~5 lines in a compressed CLAUDE.md on a solo repo. A phantom-value addition avoided.
 - **why it matters**: [[LRN-075]] (test the UNGUIDED control) paying off one chantier later — measuring the RED before building is what caught it. For UNIVERSAL conventions the model already honors (--help, common flags, standard shapes), a "teach it to do X" instruction buys nothing but tokens; the only thing left to buy is consistency, which must clear its own ROI bar.
 - **future application**: before adding any global instruction to ELICIT a behavior, run the behavioral control first — does the model already do it unaided? If yes, the only remaining value is standardization; price it honestly vs the cost (esp. a compressed CLAUDE.md). Often: don't add it.

+## LRN-081 — Commit trailers: Claude-COMPOSED content only, never on staging of user-authored text
+- **Date**: 2026-06-30
+- **pattern**: the Claude commit trailers (`Co-Authored-By: Claude …` + `Claude-Session: …`) mark Claude's ACTUAL contribution. They belong on commits whose CONTENT Claude composed — memory entries, code, docs, TODO lines drafted from intent/BDRs. A commit that merely STAGES content the USER wrote (queuing the user's own raw note) gets NEITHER trailer — author = the user, clean. Staging ≠ authorship.
+- **why it matters**: memory-commit.sh + the dev flows append the trailers BY DEFAULT → committing user-authored text through them mis-credits Claude on every note/spec the user writes. A `Claude-Session:` on a 100%-user addition is traceability noise pointing at no Claude contribution.
+- **context**: 2026-06-30 — user's `auto-skill-dispatch` planning note committed `chore(todo)` CLEAN, no trailer (`e591510`, author Bastien Chanot); vs `chore(memory)` BLK-013/BDR-043 (`5b03ac2`) WITH trailers (Claude composed those entries). The split IS the rule.
+- **future application**: before committing on the user's behalf ask "did Claude COMPOSE this content?" Composed (entry/code/doc/TODO-from-intent) → trailers. Merely staging user-written text → no trailers, user-authored. Self-referential proof: this entry + the promoted TODO follow-ups = Claude-composed → trailers OK on their commit.
