Findings 01/S-1 (AddressSpaceApplyOutcome failure field + apply.failed logging, no optimistic success), 06/S-1 (Galaxy write fails closed -> BadCommunicationError + #5 revert, no knowingly-lost raw Write), 03/S4 (PrimaryGatePolicy default-deny unknown-role-multi-driver on all gates + scripted-alarm emit gate). T13/T15 (2-node live gates) deferred -- T15 is the behavior-affecting S4 live gate, must run in heavy pass. Clean merge, build clean.
