Rig config: central pair gains Secrets__SqlServer__ConnectionString (dedicated ZbSecretsHub database on the existing scadabridge-mssql, dev credentials); site-a pair gains Secrets__GrpcHub__FallbackEndpoints__0 = central-b. Gate doc records 5/5 PASS (parity-by-construction, both-direction failover incl. recovered-primary wrap, delete-while-follower-offline with no resurrection, Layer-A expander provably reading the shared store via a stale-SQLite decoy discrimination, and fail-closed negatives), discharging the Program.cs SQL-expander offline-test residual, plus two defects documented NOT patched: the SqlServer migrator's concurrent virgin-DB CREATE SCHEMA race (error 2714 not in the retry filter) and the Host's pre-Serilog crash path wedging at 100% CPU instead of exiting.
