The systems identify movement; the team decides what it means. The arrangement is the simplest description of how the desk's detection and assessment work fit together, and it is more deliberate than the simplicity might suggest.

The systems are good at coverage. They watch a large number of sources, at the appropriate frequencies, with consistent rules about what to flag. They do not get tired, do not become distracted, do not forget to check a particular source on a particular day. Where the work is repetitive and high-volume, the systems are the right instrument.

The team is good at meaning. A flag from the systems is, on its own, just a flag. Whether it indicates something material to a particular client depends on context that the systems do not have: what the client's present situation is, what the relevant timeline looks like, what other signals it should be read against. The team supplies the context.

The handoff between them is the part that requires deliberate design. A system that produces too many flags wastes the team's attention. A system that produces too few misses material signals. The desk tunes the configuration regularly so that the volume of flags reaching the team is sustainable and the signal-to-noise is good.

The reverse handoff matters too. When the team identifies a new category of signal that should be watched (because a client's situation has shifted, because a new source has come into view, because an emerging pattern needs systematic coverage), the system is configured to begin watching for it. The team teaches the system; the system spares the team.

The result is a practice in which neither side is asked to do what the other does better. The team does not perform the routine watching; the systems do not perform the judgement. The boundary between them is the part of the work that the desk attends to most carefully.

The desk's assessments reflect this kind of reading, conducted slowly and with the corroboration the work demands.
