How to read a gap

Quota used at or near the limit

The scan stopped because the platform stopped answering. Retryable after the reset, and the missing candidates were never looked at.

Remaining unknown

Either the limit or the usage reading is missing, so the remainder cannot be computed. The endpoint returns null here on purpose — an unknown quota is not a full one, and this cell never fills itself in by assuming the missing half is zero.

Disabled

Nothing is collected from this platform. Every video it would have carried is absent from the candidate set, so it does not even appear as a coverage gap on the scan surface.

Never run

Connected and never exercised. A clean queue proves nothing about this platform, because nothing has been asked of it.

No cadence recorded

No schedule is stored. This is not the same as a manual source — the column is empty, and what triggers a run is not recorded anywhere this console can read.
