Backend becomes authoritative for the verifier signal. recordOutcome now overrides the client-supplied wasRealCollision with deriveWasRealCollision(): a flagged collision counts as REAL only if BOTH named engineers currently have the collided file in their git changedFiles (getGitStates, 120s freshness TTL). Conservative false when the collision is orphaned/missing or git state is stale. Restores the (accepted x wasReal) 2x2 the spec assumes instead of the hardcoded 107/107 true. frontend/useInterventions.ts stops sending a hardcoded `true` (now a backend-overridden placeholder). Spec: continual-learning/spec.md:98-108, policy.md:35-42. backend+frontend typecheck + eslint pass. PLAN.md P0.5 rung 3 added. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
