A pass is a fact about light, not about output. The desk reads it as a coarse proxy with a stated mechanism, never as a number.

Supports
Whether a site is being worked, and whether high-temperature process equipment is running, at coarse resolution and with a known revisit gap.
Does not support
Output, throughput, or which specific line is running. Cloud cover creates gaps, not zeros — an absence of a pass is not an absence of activity.

How the desk reads this family
Fix the footprint
The same coordinates, pass over pass, so the comparison is honest.
Separate weather from signal
A cloud gap and a real change in activity look identical until checked.
Find the second record
A grid, hiring, or procurement reading over the same period.
State the falsifier
The next clear pass that would contradict the read.
Known blind spots
- Persistent cloud cover over the site of interest
- Sites without a usable revisit cadence
- Activity that produces no optical or thermal signature
Ask the desk agent to run a named series against a holding you follow — Alpha reads the registry's labeling before it answers.
