ConfigureSharedLogger had no production caller, so the pool's only diagnostics (first-wins options conflicts, scheduler/close failures) went to NullLogger. DriverFactoryBootstrap now configures it from the driver registry factory and from the AbCip/AbLegacy probe factories (admin-only nodes reach the pool only through Test Connect). Wiring tests reset the pool to a null logger first, so removing the call goes red (verified). Claude-Session: https://claude.ai/code/session_01Ef2ozxS7QPanGT8uoATbTe
