Artifact: JTBD Job Story — Kestrel Shift Coverage

A job story for Kestrel's "who can cover this shift" need -- exercises co-03. Kestrel is a fictional product; every quoted number, question, or finding here is an illustrative, constructed example, not real data or a real transcript.

When one of my best cashiers texts me an hour before their shift saying they're sick, I want to instantly see who's already qualified and available to cover, so I can fill the shift without calling six people one by one, and still open the store on time.
