 `Invoke-IntegrationRunbook.ps1` orchestrates all phases with logging and artefact capture.
 
+When the `Loop` phase runs with the TestStand-backed host-fabric surfaces, the runbook JSON now carries
+`Loop.details.executionTopology`, including the runtime surface, process-model class, execution-cell lease,
+and harness lease identity. That gives downstream consumers a stable ownership chain instead of opaque loop output.

+For local runs, `tools/Local-Runbook.ps1` now auto-stages a runbook JSON report whenever the `Loop` phase is included
