All 10 build-order stages complete and unit-tested (49 tests). Verified live on mainnet: registration/address derivation, deposit crediting, a real 10 PLM bet (broadcast + confirmed + change credited). A full round close->draw->payout cycle was triggered live and was in progress at commit time. Withdrawal and RBF bump are unit-tested but not yet exercised against a live broadcast. Known gaps (scheduler doesn't resume mid-flight rounds after restart, payout has no retry, no deployment setup, etc.) are documented in CLAUDE.md.
