 If EdgeEnv preserves an Orchestrator `operation_risk_summary`, Lab shows the compact queue-pressure, max-pressure task, worker-health, and producer/device-local event markers as navigation context in the Runtime Intelligence Risk Summary. These markers help reviewers find the relevant operation evidence, but they do not become EdgeEnv regression deltas, comparability fields, or a deployment decision override.
 
+When the EdgeEnv preservation path is present, Lab also renders a `Lab EdgeEnv
+preservation context` row with `lab_report_preservation_context_present=True`,
+`lab_preservation=present`, and `lab_context=present`. This keeps Lab's
+Runtime Intelligence artifact gate aligned with the entrypoint evidence index
+without making EdgeEnv the deployment decision owner.
+
 If the Orchestrator feed includes `runtime_task_event_summary`, Lab also renders a task-level event rollup showing which workload had scheduler delay, deadline misses, fallback decisions, or drop/policy reasons. This is report navigation context only; Lab still owns the deployment decision.
 
 If AIGuard also emits `edgeenv_orchestrator_operation_risk_summary`, Lab renders that deterministic evidence as a separate operation-risk summary row. This keeps the AIGuard warning explanation visible while preserving Lab as the final deployment decision owner.

 - The same gate requires Orchestrator's AIGuard evidence candidate hint to preserve `runtime_queue_overload` and `runtime_thermal_instability`, keeping runtime operation anomaly evidence deterministic and supplemental.
 - The same gate requires Orchestrator candidate context to carry `run_id`, `telemetry_source`, `operation`, and `resource`, so Lab can verify handoff completeness without treating Orchestrator context as a regression judgement.
 - The same gate requires EdgeEnv-preserved Orchestrator producer markers to carry `source_repository=InferEdgeOrchestrator`, `artifact_role=orchestrator-supplemental-operation-context`, and `producer_contract=inferedge-orchestrator-edgeenv-runtime-telemetry-feed-v1`.
+- When EdgeEnv preservation context is present, Lab renders `Lab EdgeEnv preservation context` with `lab_report_preservation_context_present=True`, `lab_preservation=present`, and `lab_context=present` so the Runtime Intelligence report gate and entrypoint evidence index use the same Lab-owned marker vocabulary.
 - When an EdgeEnv handoff manifest is provided, the bundle gate requires EdgeEnv-produced file keys, external AIGuard file keys, source repository mapping, artifact roles, producer contracts, and boundary flags to match Lab's Runtime Intelligence bundle contract.

 - The same handoff gate verifies that the referenced `runtime_telemetry_history` artifact exists and preserves EdgeEnv history schema, telemetry coverage, and Runtime history seed ownership markers.
 - The same handoff gate verifies that missing telemetry entries remain evidence gaps while preserving Orchestrator producer markers, owner boundary flags, and EdgeEnv mapping hints when Orchestrator context is attached.
 - The same handoff gate validates `edgeenv_report_summary.producer_lineage_guard_alignment_run_ids` against the preserved EdgeEnv regression context so the Orchestrator-declared `edgeenv_orchestrator_producer_lineage` marker cannot disappear between EdgeEnv producer output and Lab bundle ingestion.
