 - Shipped config-protection hook (feature/config-protection-hook): PreToolUse blocks Edit/Write to quality-gate files (settings/gitflow/.githooks/doctor/hooks-self/lib-tests/lint). One-shot sentinel .claude/.config-edit-ok (non-empty reason, logged+consumed) — NOT env-var (launch-time = set-and-forget = garde mort). Own idiom, not ECC import. shellcheck clean, test 20/20.
 - Live dogfood: hook went active mid-session via symlinked settings (link.sh); v1 (no self-guard) let its OWN edit through → v2 added hooks/*.sh + lib/tests/* self-guard, then blocked the test-file edit; recovered via sentinel. User's self-guard requirement vindicated.
 - Next: #2 design-toolchain trigger fix (residual false-fires post-ed2408e, 5× this session).
+- #2 done (bugfix/design-toolchain-trigger): trigger tightened — dropped bare design|component|composant|theme|thème|transition|frontend|front-end|palette; dashboard→\bdashboard\b (kills ecc_dashboard.py filename match, keeps "admin dashboard"); kept animation; added "front-?end design" bigram + fire-log counter (time+token+excerpt, ~/.claude/logs/design-toolchain-fires.log) so future "re-firing?" is measured. Test 18/18, shellcheck clean, live dogfood green. [[LRN-091]] corrob [[LRN-047]].
+- Double dogfood of #1 guard: config-protection blocked + sentinel-bypassed my own edits to the now-guarded design hook + its test — first real use of the guard, friction validated in passing (one-shot sentinel .claude/.config-edit-ok, non-empty reason, logged+consumed). ECC second-regard closed: #1 config-protection + #2 trigger fix, both merged to develop, nothing pushed.

 - **context**: ECC 2nd-look 2026-07-03 (Opus 4.8, 6 agents, repo unchanged since 01/07). [[BDR-047]] audit (01/07) inventoried the declarative surface + concluded zero import — right on facts, but hooks/ (ECC's only live subsystem) was OUT of scope and held the sole real adaptation → config-protection PreToolUse guard.
 - **future application**: next external-repo value audit → enumerate hooks/, scripts/, runners FIRST; treat rules/docs/SKILL.md as claims to verify ("is it wired?"), not value. Described capability ≠ wired capability.
 - **cousin**: [[LRN-087]] presence-flag ≠ capability; [[LRN-089]] forwarded-args silently dropped — same family: a visible signal (a file, a flag, a `paths:`) lying about real behavior.

+## LRN-091 — a soft-nudge hook that over-fires gets ignored (banner-blindness)
+- **pattern**: keyword-triggered nudge (design-toolchain reminder) with bare common tokens fires on non-UI work → reader tunes it out. Same class as a diagnostic that cries false [[LRN-047]]: a signal wrong too often stops being read.
+- **rule**: keep a token BARE only when its UI sense dominates largely in a dev context (glassmorphism, navbar). Token common in non-UI talk (design, component, theme, transition, frontend) → require a UI-specific bigram (design system, front-end design) or drop; in doubt → bigram-or-drop. Borderline standalone nouns (dashboard, animation) may stay bare as an assumed call — the fire-log arbitrates later on data, not gut. (NOT "never bare tokens" — animation stays bare here by design.)
+- **context**: design-toolchain-reminder.sh — 07-02 tightening (dropped page/form/menu/…) insufficient; 6 bare tokens still false-fired ~6×/session during the ECC config audit (design, ecc_dashboard.py, component, frontend, theme, transition, palette). 07-03 fix: dropped them, dashboard→`\bdashboard\b` (filename match killed, "admin dashboard" kept), added a fire-log (time+token+excerpt). `lib/tests/design-toolchain-reminder.test.sh` locks it (18 checks).
+- **cousin**: [[LRN-047]] a doctor that cries false is ignored.

+(design, dashboard via ecc_dashboard.py, component, frontend, theme, transition,

+- [ ] hooks/design-toolchain-reminder.sh — drop bare design|component|composant|theme|thème|transition|frontend|front-end|palette; dashboard→\bdashboard\b; keep animation; add "front-?end design" bigram; + fire-log (time+token+excerpt)
+- [ ] lib/tests/design-toolchain-reminder.test.sh — 8 dropped tokens quiet; button/navbar/landing/glassmorphism/redesign/"frontend design"/"admin dashboard"/animation fire; ecc_dashboard.py quiet; fire logged

 Goal: PreToolUse hook blocks Edit/Write to this config's quality-gate files
 (guardrails an agent must not weaken to make an error pass). Adaptation from ECC
