 - **Why**: /harden had a real scale (SKILL.md:435), /seo had NONE → every axis felt → two runs over identical code diverged, while /client-handover gates on 17/20. H2 sharpened it: once drift reports real change, a self-moving score is visibly noise. Same principle as engine-side cannibalisation grouping — never hand a model 1000 rows to add.
 - **Makes computable (was prose)**: "N/A is not a zero" (R2 on-page, I1 off-page) → axis excluded + weights renormalised, verified all-20 with 2 N/A → global 20.0. Prevalence: affected/sampled shift severity ONE step (≥50% escalate, single de-escalate).

+### BDR-074 — Remove config-protection edit-block guardrail [accepted] (2026-07-17)
+Deleted hooks/config-protection.sh + its settings.json PreToolUse registration + lib/tests/config-protection.test.sh. Hook blocked model Edit/Write on quality-gate files (settings.json, gitflow.sh, .githooks, doctor.sh, hooks, lib/tests, lint) via one-shot .claude/.config-edit-ok sentinel. Removed per user req — friction editing own config > guardrail value; user = human operator. Residual: gitflow pre-commit guard + Gitea branch protection still block direct code commits main/develop; only edit-time block gone. Alts rejected: warn-only (exit0+log), targeted relaxation. Supersedes any prior config-protection decision.

+### BDR-075 — Framework-wide 3-way adversarial plan-challenge phase [accepted] (2026-07-17)
+After a plan/reflection elaborated + before execution, 3 fresh blind sub-agents (correctness/robustness/simplicity) attack it; main loop RE-THINKS every aspect a BLOCKER lands (named change or [deferred]) + re-challenges once if plan materially changed. Reusable lib/challenge-plan.md + new agents/plan-challenger.md (read-only, big-model per [[BDR-066]] — audit judgment, NOT sonnet). Fail-safe (never fail open: mute→retry→escalate), severity-driven (any single-lens BLOCKER=must-address, NOT consensus — lenses orthogonal), advisory into existing human gate. KIND tunes lenses: build-plan/proposals/fix-bundle. Wired 11 orchestrators: ship-feature/init-project/feat/bugfix + onboard/audit-delta/code-clean + seo/geo/harden/web-validate. Excluded (no real plan): hotfix/tour/analyze/client-handover/release-candidate/spec. Audit found 0 repo-owned plan-challengers pre-existing (only vendored gstack autoplan, sequential+unwired). See [[EVAL-026]].

 - **anomalies**: 7/7 of the verifiable claims were false or overstated (VSI exists / Off-page zero-data / stats drive weights / GSC Links API / SPA §0 flag / Twitter 403 / Common Crawl viable). 6 plan corrections mid-execution: I1 over-correction, I6 wrong framing, W1 wrong shape (verb vs extend), C1a false premise (grep already skips gitignore), C1b needless guard, B1 non-viable at 17.3 GB. The REAL corrected every time; re-reading the spec never did.

Method that worked: show/measure the real artifact before deciding, mirroring [[LRN-074]]'s watch-the-RED discipline applied to a plan.

+### EVAL-026 — 3-way plan challenge caught 4 BLOCKERs dogfooding own plan (2026-07-17)
+Dogfood: 3 blind lenses attacked the v1 plan for the plan-challenge feature itself. Verdicts CONCERNS(4)/FATAL(6)/FATAL(4). Caught 4 distinct BLOCKERs a single pass would blend: (1) v1 unbuildable — targeted init-project (inline-load, no dispatch) + false "plan on disk" premise for feat/bugfix (only contract persists); (2) failed-open silently dropping a lens while claiming "challenged" (inverts verify-secure-loop "a mute verifier is NEVER a PASS"); (3) consensus-weighting buries lone L2 security finding (lenses orthogonal); (4) sonnet challengers violate [[BDR-066]] (audit judgment=big model). Synthesis REJECTED 1 false positive (allowed-tools-blocks-dispatch — ship-feature has same frontmatter + dispatches fine). Each lens found a DIFFERENT class of flaw → evidence 3-independent > 1-multilens. Action: hardened v2 (severity-driven + fail-safe + re-think loop) shipped. Method validated itself before build.

+### LRN-136 — config-protection live state follows checked-out branch's symlinked settings.json (2026-07-17)
+~/.claude/settings.json is a SYMLINK to the repo settings.json; Claude Code hot-reloads settings on change → the config-protection PreToolUse hook's active/inactive state tracks the CURRENT branch's settings.json. On feature/drop-config-protection (hook deregistered) a protected edit passed silently, sentinel unconsumed; after gitflow-switch to a branch off develop (hook still registered) the SAME class of edit was blocked. Apply: a change that removes a settings-registered hook is live only on that branch until merged; use the one-shot sentinel for protected edits on any branch that still registers it. ([[BDR-074]] context.)
