Chiifa

Chiifa is a multilingual administrative appointment assistant for patients and demonstration doctors. An Expo / React Native app connects to a NestJS backend and PostgreSQL. Meta Muse Spark 1.3 interprets French, Arabic and English administrative requests into strictly validated structured intentions. Patients browse fictional doctor profiles and real backend availability, then explicitly confirm bookings or cancellations. Doctors can read only their own planning and propose a new time; the original appointment stays confirmed until the patient accepts an atomic transfer. The model cannot execute SQL or automatically mutate appointments. Server-side role/ownership checks, transactions, database exclusions, idempotency and administrative audit records protect each command. Real PostgreSQL E2E testing passed ten main scenarios; two optional scenarios were skipped. Samsung A07 testing demonstrated patient login, catalogue reads, a confirmed booking and doctor planning. Real Meta API calls returned HTTP 200. The latest Android AI display check and full Android rescheduling flow remain incomplete; the APK is built but standalone installation is not yet verified. All identities and profiles are fictional and marked NOT_VERIFIED_DEMO. Chiifa does not interpret symptoms, diagnose, recommend treatment or perform clinical triage. It is a TEST prototype, not a clinical or production service.
