Field test plan

Pairs are frozen snapshots saved from the map demo ("Save for field") — one O/D pair answered by all three product profiles (fast / calm / safe). Assign one pair, walked mode, day, and walk window per tester below; each tester then opens their personal /field link on their phone. Assigning the same pair to several testers is deliberate (the multi-walked subset for inter-rater agreement) and is marked with a ×N badge. Feedback collects at /api/v1/field/feedback (one JSON row per annotation) and is reviewed on the field review page. Full workflow: see the manager guide; send testers the tester guide with their links.
