- Migration v2: INSERT → INSERT OR IGNORE for idempotency - Config: validate server.tls_cert and server.tls_key are non-empty - gRPC: add input validation matching REST handlers - gRPC: add logger to zone/record services, log timestamp parse errors - REST+gRPC: extract SOA defaults into shared db.ApplySOADefaults() - DNS: simplify SOA query condition (remove dead code from precedence bug) - Startup: consolidate shutdown into shutdownAll(), clean up gRPC listener on error path, shut down sibling servers when one fails Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
