DriverHostActor.ApplyAndAck now reads the deployment artifact and reconciles its set of DriverInstanceActor children — spawn the missing, ApplyDelta to those with changed config, stop the removed/disabled. The diff lives in pure DriverSpawnPlanner so it can be unit-tested without an ActorSystem. Adds IDriverFactory in Core.Abstractions (consumed by Runtime) + DriverFactoryRegistryAdapter in Core.Hosting that wraps the existing v1 DriverFactoryRegistry — Runtime stays decoupled from Polly/Serilog, the Host wires the adapter once driver assemblies have registered. ShouldStub(type, roles) is now actually called on every spawn — Galaxy + Wonderware-Historian boot stubbed on macOS/Linux or whenever the host carries the dev role. Missing factory ⇒ stub fallback, never a crash. Tests: 24 → 34 in Runtime (+10): - DriverSpawnPlannerTests x7 (diff cases, type change ⇒ stop+respawn) - DeploymentArtifactTests x5 (empty/malformed/missing fields tolerant) - DriverHostActorReconcileTests x4 (spawn count, stub fallback, ShouldStub gate, second-apply stops the removed) All 6 v2 test suites green: 120 tests passing. Closes F20 (ShouldStub wired). F7 marked partial — subscription publishing + write path still stubbed in DriverInstanceActor itself.
