AB-PHOS OS — the Ayushman Bharat Planetary Health Operating System (iOS-style light theme). Default frame: 8″ tablet — switch device and orientation above. The home screen is role-based: switch the signed-in role from the lock screen, Control Centre or Settings and the app set changes — Citizen, ASHA, CHO, Medical Officer, District Programme Officer, ICCC Operator (war-room apps: call centre, ambulance positioning & assigning) and Super Admin (builders & masters). Tap the clock to open Control Centre & notifications · ⧉ shows the app switcher · the bottom bar goes home. One core database: every list drills to the record, records link across apps, and every action writes once to a shared ledger with surface attribution — propose an update in the Citizen app, then switch role and watch it arrive in Approvals, ICCC Follow-ups and the Database app. Built to the AB-PHOS Consolidated Edition v1.1: the Longitudinal Records & Analytics app (timeline · matrix · episodic), adoption waves 0–3, the mobility rule (the record follows the person, the slice follows the jurisdiction), the differential privacy policy with break-glass, and differential services at differential levels. All data illustrative; everything runs in this file.
