Offline-first: all core field functions work with no connectivity for extended periods; sync is delta-based and conflict-resolved.
Performance: map with typical block-level data loads in a few seconds on a mid-range Android device; queue and score recompute on sync without blocking the UI.
Scalability: architected to grow from one block to national volume without redesign (tenant-per-state, partitioned geospatial store).
Reliability and data integrity: no data loss on crash mid-visit; every record traceable to who/when/where.
Security: encryption in transit and at rest; device-level protection for cached identifiable data; remote wipe for lost devices.
Explainability and auditability: every AI output carries a reason and is logged with model version.
Accessibility and localization: multilingual, low-literacy-friendly, sunlight-readable, low-bandwidth.
Interoperability: ABDM-compliant, FHIR-based data exchange where applicable, ABHA linkage.
