Adds the Calculation pseudo-driver (tags computed by C# scripts over other tags' live values) plus the host seam that feeds it: - IDependencyConsumer capability interface (Core.Abstractions) + DriverTypeNames.Calculation. - CalculationDriver : IDriver, ISubscribable, IReadable, IDependencyConsumer — change-gate + dedupe (VirtualTagActor parity), timer-group scheduler, Bad-transition + script-log emission, Good recovery; reuses the T0-4 CalculationEvaluator. - DriverHostActor spawns a DependencyConsumerMuxAdapter per dependency-consuming driver, registering its refs on the per-node DependencyMuxActor and forwarding DependencyValueChanged → OnDependencyValue; re-registers on every apply, torn down with the driver. - Factory + probe registered in DriverFactoryBootstrap (keeps the T0-3 guard green); guard test csproj references the driver so the bin-scan discovers the factory. - DeploymentArtifact injects the resolved scriptSource (scriptId → SourceCode) into a calc tag's delivered TagConfig so the host-blind driver can compile it. - DraftValidator deploy gates: CalculationScriptMissing / CalculationScriptNotFound (scriptId existence) + CalculationDependencyCycle (DependencyGraph.DetectCycles over calc→calc edges). - Tests: driver units (dep-ref extraction, change-gate, dedupe, Bad+script-log+recovery, timer, read), tag-config parsing, DraftValidator gates (self/2-cycle/cross-driver-terminal), and a Runtime integration test proving values FLOW mux → adapter → driver → calc-of-calc end-to-end.
