## backend-phase-4 — Geography, addresses & nurse service areas — 2026-07-02
- **Shipped:** five tables via one migration (`GeographyAddressesServiceAreas`) — new **`geo`** schema
  `Provinces` 1:N `Cities` 1:N `Districts` (+ `NurseServiceAreas`) and `usr.CustomerAddresses`; seed
  (31 provinces + capital cities + Tehran's 22 مناطق via `HasData`); 20 CQRS slices across 4 controllers
  (`geo` public lookups incl. `/tree`, `admin_geo` CRUD + set_active, `nurse_service_areas`,
  `customer_addresses`); new **`IGeocoder`** seam (deterministic mock, `Seams:Geocoding`); per-domain
  repos on `IUnitOfWork`; enc value converters for the address PII columns; **`409 Conflict`** added to
  `OperationResult`/`BaseController`. Whole-city (`district_id NULL`) uniqueness via a **filtered-index
  pair**; single-primary address via filtered `UNIQUE(customer_id) WHERE is_primary=1`; geo reads cached
  behind a generation-token scheme with invalidate-on-admin-write.
- **Contracts:** dev/contracts/domains/geography-addresses.md + openapi snapshot refreshed (yes — 20 new
  geo/service-area/address paths).
- **Mocked:** `IGeocoder` → 🟡 (see reports/mocks-registry.md).
- **Gate:** build clean (0 new code warnings) / tests green (103 pass: +16 `Baya.Test.Api` integration,
  +12 handler unit tests). Migration `GeographyAddressesServiceAreas` applies on startup; swagger exposes
  all b4 paths.
- **Handoff:** backend/handoff/after-backend-phase-4.md
- **Notes for frontend:** `districtId=null` means **whole city** (a real choice) everywhere. Duplicate
  service area → **409**. Addresses come back **decrypted for the owner** with `latitude`/`longitude`
  (nullable when ungeocoded — geocoding is mocked). Routes are action-style (`admin_geo/create_city`,
  `nurse_service_areas/add`, `customer_addresses/create`, …). Admin geo needs an admin token.

## backend-phase-3 — Identity: profiles, patients & nurse bank accounts — 2026-07-02
- **Shipped:** four `usr` tables via one migration (`IdentityProfilesPatientsBankAccounts`) —
  `NurseProfiles` (1:1 `Users`; guarded `is_verified` **no public setter**; read-only aggregates;
  soft-delete), `CustomerProfiles` (thin payer; enc emergency contact), `Patients` (care recipient,
  tenancy-scoped; `is_active` archive; enc `initial_medical_notes`), `NurseBankAccounts` (enc `iban` +
  `UNIQUE(iban_hash)` + filtered `UNIQUE(nurse_id) WHERE is_primary=1`; استعلام شبا inquiry fields);
  15 CQRS slices across 4 controllers (`nurse_profiles`, `customer_profiles`, `patients`,
  `nurse_bank_accounts`); new **`IBankAccountOwnershipVerifier`** seam (mock = deterministic شبا match);
  per-domain repositories on `IUnitOfWork`; enc value converters for the new PII columns. Also
  **activated FluentValidation** repo-wide (`AddApplicationServices` now registers every
  `AbstractValidator<T>` — the `ValidateCommandBehavior`/model-state filter were previously starved).
- **Contracts:** dev/contracts/domains/identity-profiles.md + openapi snapshot refreshed (yes — new
  nurse/customer/patient/bank paths).
- **Mocked:** `IBankAccountOwnershipVerifier` → 🟡 (see reports/mocks-registry.md).
- **Gate:** build clean (0 new code warnings) / tests green (75 pass: +13 `Baya.Test.Api` integration,
  +15 handler unit tests). Migration applied to the dev DB on startup; swagger exposes all b3 paths.
- **Handoff:** backend/handoff/after-backend-phase-3.md
- **Notes for frontend:** role scoping needs the **role claim in the token** — refresh after
  `select_role` before calling these. IBAN comes back **masked** (last-4). `isVerified`/aggregates are
  read-only. Patient `get/update` of another customer's id → **404**. Addresses/service-areas are
  **deferred to b4**.

## backend-phase-2 — Identity: phone-OTP auth, sessions & roles (REST) — 2026-07-02
- **Shipped:** the six-endpoint REST auth surface (`auth/request_otp`, `auth/verify_otp`,
  `auth/refresh`, `auth/logout`, `me`, `me/select_role`) wrapping the existing JWE/TOTP/RBAC engine;
  new `usr.UserSessions` (refresh-token rotation + revoke-all on replayed token); `usr.Users` extended
  (`Gender`, `NationalId` enc NULL, `ShahkarVerifiedAt` auto-reset on phone change, `PhoneHash`
  UNIQUE, `IsActive`, `DeletedAt` + soft-delete filter); phone/email/national-id **encrypted at rest**
  (EF value converter over `IFieldEncryptor`); `usr.UserRoles` grant/revoke audit trail + revoked
  filter; 7 roles seeded; `ISmsSender` seam (mock logs the code); 3 auth config keys;
  `OperationResult`/`BaseController` learned 401/403.
- **Contracts:** dev/contracts/domains/identity-auth.md + openapi snapshot refreshed (yes — 22 paths).
- **Mocked:** `ISmsSender` → 🟡 (see reports/mocks-registry.md).
- **Gate:** build clean (0 new code warnings) / tests green (47 pass: 10 new `Baya.Test.Api`
  integration + 14 new handler unit tests). Migration `IdentitySessionsAndUserExtensions` applied to
  the dev DB; full §7 flow verified live (OTP in log, tokens, 401/403/429, rotation, replay-revoke,
  logout stamp-kill).
- **Handoff:** backend/handoff/after-backend-phase-2.md
- **Notes for frontend:** exact paths are `request_otp`/`verify_otp`/`select_role` (snake_case
  transformer — not the `otp/request` sketch). Bodies camelCase. Fresh users: `roles: []` → role
  router → `me/select_role` → **refresh tokens** to pick up role claims. `/me` phone is masked.
  SMS is mocked — read the OTP from the server log.

## backend-phase-1 — Config, reference & platform signals — 2026-07-02
- **Shipped:** first marketplace migration baseline (`InitialMarketplaceBaseline`, new **`ops`** schema)
  with 6 tables (`PlatformConfigs`, `AuditLogs`, `SystemEvents`, `IranianHolidays`, `Notifications`,
  `SupportAlerts`) + seed (12 config keys, 7 holidays); platform-signal facades `IPlatformConfig` /
  `IHolidayCalendar` / `IAnalyticsSink` / `IAuditLogger` / `INotificationService` / `ISupportAlertService`
  (`Persistence/Services/`); `AuditFieldInterceptor` extended to write append-only `audit_logs` rows for
  `IAuditable` entities; real in-app `INotificationDispatcher` (b0 stub removed); notification-retention
  hosted service; 5 controllers (admin config/holidays/audit/support-alerts + current-user notifications).
- **Contracts:** `dev/contracts/domains/config-reference.md` + openapi snapshot refreshed (yes — 16 paths).
- **Mocked:** `IHolidayCalendar`, `IAnalyticsSink`, retention `IJobScheduler` → 🟡; `INotificationDispatcher`
  flipped to in-app-real 🟡 (SMS/push deferred). See reports/mocks-registry.md.
- **Gate:** build clean (0 new code warnings) / tests green (22 pass: 4 identity + 18 foundation). Migration
  applied to the dev DB; API boots with all 16 paths in Swagger; retention job runs on startup.
- **Handoff:** backend/handoff/after-backend-phase-1.md
- **Notes for frontend:** f14 = `notifications/*` (envelope unchanged; unread-first lists; `data_json` is a
  typed deep-link payload). f15 = admin `platform_config/*`, `holidays/*`, `audit/get_audit_trail`,
  `support_alerts/*` (DynamicPermission). Pagination `page`/`page_size` (default 50, max 100).

## backend-phase-0 — Foundation, cross-cutting seams & starter cleanup — 2026-06-28
- **Shipped:** removed the `Order` demo (entity/feature/repo/config/gRPC) + 3 old migrations; fresh
  `InitialBaseline` migration; REST surface (`PingController` + `System/Ping` CQRS); `ICurrentUser` +
  `AuditFieldInterceptor`; five cross-cutting seams (`IDateTimeProvider`, `IFieldEncryptor`,
  `ICacheService`, `IObjectStorage`, `INotificationDispatcher`) with mocks; `LoggingBehavior` +
  rate limiter (per-IP global + `otp`/`auth`/`sensitive`).
- **Contracts:** `dev/contracts/openapi/swagger.v1.json` published (envelope + ping schemas).
- **Mocked:** the 5 seams above → 🟡 (see reports/mocks-registry.md).
- **Gate:** build clean (0 new warnings) / tests green (10 pass). Live API verified vs `192.168.100.14`
  (migration applied + seeded; ping `200`; rate-limit `429`).
- **Handoff:** backend/handoff/after-backend-phase-0.md
- **Notes for frontend:** `ApiResult` envelope is fixed (camelCase body, snake_case URLs);
  `GET /api/v1/ping/get_status` is live to wire types against; `429` on over-limit.
