Instrument & discovery

Changes require the administrator token configured on this server. The token stays in this browser tab’s memory.

Instrument configuration

Saving a name does not verify it or enable processing. Phase 1 keeps the processing switch disabled.

The metadata worker must be running. Pausing takes effect after the current batch commits.
