# Risks And Gaps This file tracks known gaps and risks to address in future iterations. ## Security And Auth - Phone normalization is KSA-focused and minimal; broaden for multi-country use. - OTP protections are basic; add device fingerprinting and IP throttling if needed. - Authentica OTP provider is implemented (SMS + WhatsApp via Authentica OTP); Unifonic remains a scaffold. - Social login is a placeholder. - `USERNAME_FIELD` is now `"phone_number"`; `REQUIRED_FIELDS = []`; `create_superuser` accepts `phone_number`. Admin and `createsuperuser` work correctly for phone-only users. ## Booking Integrity - Availability checks and overlap prevention are now enforced for staff bookings. - **Race condition — fixed:** `BookingCreateSerializer.create()` now locks the staff row with `select_for_update()` inside `transaction.atomic()` and re-runs the overlap check before inserting. Concurrent requests for the same staff slot are serialized at the DB level. Requires PostgreSQL in production (SQLite ignores `FOR UPDATE` but still serializes writes). - No timezone handling or business hours enforcement. - No cancellation rules or refund logic. ## Payments - Moyasar payment creation, webhook reconciliation, and idempotency are implemented. - Moyasar capture and refund are implemented in the gateway; API endpoints for admin-initiated capture/refund can be added when needed. ## Data And UX - Ratings are not recalculated from reviews. - No image upload or storage strategy for photos. - Booking lifecycle notifications are implemented; Authentica can deliver SMS when NOTIFICATION_PROVIDER=authentica. - Localization foundations are in progress; full Arabic translation coverage and RTL QA are still pending. ## Ops And Compliance - No audit logs for admin actions. - No multi-tenant isolation or data export tooling. - No GDPR/PDPL data retention policies defined. - CI baseline exists, but needs Gitea runner registration and required-check enforcement.
