Incubator events

The instrumented legacy.storage.Incubator and HighRes sample-storage frontends emit the following semantic operations where their public APIs support them:

Operation	Lifecycle events	Primary fields
incubator.fetch_plate	started, completed, failed	device, resources, source, destination
incubator.take_in_plate	started, completed, failed	device, resources, source, destination
incubator.transfer_plate	started, completed, failed	device, resources, source, destination

resources contains the direct moved plate. source and destination identify the relevant PLR holders, such as a storage site and loading tray. The completed event can reflect the plate’s post-operation resource assignment.

incubator.transfer_plate describes a direct move between two transfer nests or other incubator endpoints. The HighRes-specific environmental events are documented in its sample-storage event reference.
