After a plan/reflection is elaborated and before it executes, three fresh blind sub-agents (correctness / robustness / simplicity) attack it on the big model; the main loop RE-THINKS every aspect a BLOCKER lands (a named plan change, or [deferred]) and re-challenges once if the plan materially changed. Advisory into each skill's existing human gate — the human stays the decider. - lib/challenge-plan.md — reusable phase: fail-safe (never fail open), severity-driven (any single-lens BLOCKER = must-address), RE-THINK loop - agents/plan-challenger.md — challenger role (read-only, big-model per BDR-066) - lib/tests/plan-challenger.test.sh — 41-assertion structure lock - wired into 11 orchestrators: ship-feature/init-project/feat/bugfix (build-plan), onboard/audit-delta/code-clean (proposals), seo/geo/harden/web-validate (fix-bundle) Hardened by dogfooding: 3 blind challengers reviewed this feature's own v1 plan and caught 4 BLOCKERs (fail-open, consensus-buries-lone-finding, wrong model tier vs BDR-066, false on-disk-plan premise) — all fixed here.
