A verified trainer opens a private link and submits a 2-sentence text vouch for a specific worker's skills.
System generates an anonymous ID, logs the vouch, and texts a unique QR code directly to the worker's phone.
Worker arrives at a new barn. They do not hand over a passport or ID. They show the QR code on their phone screen.
Manager scans the QR with standard iPhone camera. It instantly opens the Stride Vouch Page proving competence.
Manager clicks "Log Shift." Stride records the timestamp for FLSA/liability purposes without storing the worker's legal name on the barn's local books.
