+The same host service reads the existing perception worker's loopback `/health`
+contract with `Get-NdcMissionCorePipelineTelemetry.ps1` and publishes nine
+stage-keyed snapshots to the contour's `pipeline` topic. The perception container
+does not receive broker credentials and no second agent container is introduced.
+These snapshots expose current durable-worker state and cumulative stage timing;
+native per-run lifecycle events remain a separate compute contract.

+When the mounted perception runner itself changes, use
+`Update-NdcMissionCorePerceptionRunner.ps1` with exact predecessor and candidate
+digests. It backs up the mounted runner, restarts the same container, accepts only a
+ready health document with stage metrics, and restores the predecessor on failure.

 The stack and agent are intentionally not started by repository tests. Provisioning a
 machine is a separate, explicit operation.
