BLOCKED / NOT POPULATED. Sheet 2 requires (a) full kept-visit enumeration 2026-04-01..2026-06-16 and (b) a future-follow-up check per kept patient (~330-400 patients). The AdvancedMD API enforces an aggressive per-hour rate limit (both API seats hit 60-minute cooldowns after a few dozen calls), making a complete + CORRECT Sheet 2 infeasible in one run (would need many hours of throttled calls). A partial enumeration (only 4/1-4/23 was retrieved) would produce incorrect 'last kept date' / 'Days Since' values for patients also seen later in the window, so it was intentionally NOT shipped to avoid a misleading reactivation list. RECOMMENDATION: run a scheduled/throttled overnight backfill (per-day get_visit_info_by_date across 4/1-6/16 + future dates 6/17+ to detect existing follow-ups, OR get_appointment_history per kept patient) to populate this sheet correctly.
