Deployment Manager (WP-1–8, WP-16): - DeploymentService: full pipeline (flatten→validate→send→track→audit) - OperationLockManager: per-instance concurrency control - StateTransitionValidator: Enabled/Disabled/NotDeployed transition matrix - ArtifactDeploymentService: broadcast to all sites with per-site results - Deployment identity (GUID + revision hash), idempotency, staleness detection - Instance lifecycle commands (disable/enable/delete) with deduplication Store-and-Forward (WP-9–15): - StoreAndForwardStorage: SQLite persistence, 3 categories, no max buffer - StoreAndForwardService: fixed-interval retry, transient-only buffering, parking - ReplicationService: async best-effort to standby (fire-and-forget) - Parked message management (query/retry/discard from central) - Messages survive instance deletion, S&F drains on disable 620 tests pass (+79 new), zero warnings.
