Recall reminder automation kaise on karte hain — kis patient ko jaata hai?

Recall automation weekly cron hai — Sunday 08:00 IST. Wo un patients ko dhoondhta hai jinka pichle 6 mahine me koi poora hua visit (PT Out / Engage) nahi hai. Filter itne hi zaroori hain jitna cron: patient kam se kam 2 mahine purana ho (naye registration ko recall bhejna bewakoofi hai), deceased mark na ho, smsDnd na ho. Aur do rakshak hain — ek run me ek clinic ke max 50 patient (blast storm rokne ke liye), aur ek patient ko 90 din ka cooldown, yaani jo patient lapsed pada rehta hai use har hafte dobara nudge nahi jaata, quarter me ek baar. Cooldown query ke andar hai, isliye jin clinics me 50 se zyada lapsed patient hain wahan bhi list ghoomti rehti hai — pehle 50 par atki nahi rehti (least-recently-contacted pehle). Message unified facade se jaata hai, clinic ke apne WhatsApp/SMS provider ke saath — WhatsApp hub ki patti laal ho to Sent Log me 'Ruka'. DEFAULT OFF hai — jab tak clinic khud '📢 Automated Patient Messages' me 'Recall reminders' on na kare, ek bhi recall nahi jaata; pehle ye switch mobile par tha hi nahi, ab web + mobile dono par hai aur save ke baad wapas padh kar dikhta hai. Usi section me 'Treatment plan reminders' (daily 9:00 AM) ka alag switch hai.
