+  ONE scope gap: BDR-047 never opened hooks/ — ECC's only WIRED subsystem. Fruit:
+  config-protection hook (own idiom, NOT ECC import), shipped

 - Same branch, 3 doctor false-warns fixed ([[LRN-047]] corrob — a doctor that cries false is ignored): cargo "(RTK unavailable)" → optional info (RTK prebuilt, detect_rtk); check_symlink passes children of dir-level symlinks (hooks/session-start.sh); gstack counts 34 per-skill symlinks not a mythical skills/gstack link (link.sh removes it); token budget vs 200k context window not bogus 11k "session budget" → killed false "92% CRITICAL" (measured ~11.4k [[LRN-088]]; 200k confirmed by user — 1M pin revoked at audit #7, calibrate on default not the exceptional session).
 - Suites green: gitflow 71/71 (+7), deterministic 13, doc-commit 32, doc-shape 19, reconcile 20, deploy-commit 13, release-candidate 5/5 tag-mode. doctor: 0 false-warn (1 legit survivor = gstack tracks branch=main advisory). shellcheck clean. T12 named to dodge collision with reconcile's own T6c (darwin path, audit #3).
 - 3 atomic commits (fix gitflow / fix doctor / docs changelog Unreleased) + memory. finish bugfix→develop on GO; user pushes develop.
+- ECC 2nd-look (Opus 4.8, 6 agents, repo unchanged since 01/07): all [[BDR-047]] facts corroborated w/ file:line, zero divergence. Scope gap = hooks/ (only wired subsystem) unaudited 01/07 → [[LRN-090]] wired > declarative.
+- 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).

Never let forwarded args be silently dropped: silent-drop = the caller believes they steered, the callee ignored them.

+## LRN-090 — external-repo audit: open WIRED subsystems before declarative
+- **pattern**: auditing external config/framework repo for transferable value → rank subsystems WIRED (executable: hooks/, runners, dispatchers) vs DECLARATIVE (docs, rules/, aspirational frontmatter). Wired > declarative: declarative often inert (ECC rules/ `paths:` = 0 consumers; eval-harness = SKILL.md, no runner — "belle méthodo / vaporware"); wired = a real mechanism worth adapting.
+- **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.
