+license: Apache-2.0

+  version: "1.0"
+---
+
+## Activation Contract
+
+Load this skill when creating a new collection or a new endpoint in the `server` backend of the turnosxpress admin (the API consumed by admins/employees, not the public client app). Applies to both the data layer (`server/src/Models`) and the HTTP layer (`server/src/api`). Example to imitate: `Clients`, `Posts`, `SchedulesDisabled`.
+
+## Hard Rules
+
+- Use the ACTUAL paths: collections live in `server/src/Models/<Name>/`, endpoints in `server/src/api/<Name>/`. The folder name is the collection name (e.g. `Clients`, `Posts`).
+- A collection is ALWAYS exactly 3 files with separated responsibilities (never collapse them):
+
+| File | Owns | Forbidden here |
+|------|------|-----------------|
+| `<Name>.Interface.ts` | All TS types: `*Params` (Create/Update/Delete/Find), `IX`, `IXDocument` re-export, `IXAdapter`, `IXManager`, view/result types. | No Mongoose, no business logic. |
+| `<Name>.Adapter.Mongoose.ts` | Mongoose ONLY: `Schema`, `IXDocument extends IX & Document`, `model()`, and pure DB ops (`create`, `delete`, `find`, `findOne`, `paginate`). Implements `IXAdapter`. | No business rules, NO security checks. |
+| `<Name>.ts` | Business rules AND security. A `<Name>Manager implements IXManager` class that instantiates the adapter in the constructor; exported as a singleton (`const XList = new ...Manager(); export default XList;`). | No Schema, no `model()`. |
+
+- SECURITY STANDARD (mandatory, even though `Clients.ts` inlines it — that is legacy): use the shared helpers from `server/src/helpers/check.ts`:
+  - `validateSessionUser({ sessionUser })` — confirm the session user exists. Call FIRST in any method that receives `sessionUser`.
+  - `validatePermissionsByCompany({ companyId, sessionUser })` — confirm the company exists AND the session user has ADMIN role. Call whenever a `companyId` is involved.
+  - Modern reference: `server/src/Models/Posts/Posts.ts`, `server/src/Models/SchedulesDisabled/SchedulesDisabled.ts`.
+  - Role checks beyond ADMIN (EMPLOYEE, etc.) go through `EmployeesList.checkPermission` / `checkRoleById`.
+- An endpoint is ALWAYS 2 files:
+  - `<Name>.Controller.ts` — tsoa decorators. One controller class per `@Route("resource/action")`. Each handler `@Post()`, takes `@Body()`, sets status, wraps in try/catch and returns `new ApiValidationError(500, message)` on error. Import `ApiValidationError` from `../../Models/Server.Error.model`.
+  - `<Name>.Service.ts` — thin: each method `await connect(process.env.DATABASE_CONNECTION)` then delegates to the manager singleton. No business logic here.
+- `authenticationMiddleware` (from `server/src/middleware/authentication.ts`) MUST be applied with `@Middlewares(authenticateMiddleware)` on EVERY controller, UNLESS the endpoint is intentionally public. Never omit it without explicit confirmation (see Ask Before Building).
+- 99% of endpoints use `@Post()`. Default to POST; use GET/other only with a concrete, justified reason.
+- After adding/changing controllers, regenerate the tsoa routes/spec: `npm run routes` (binds `tsoa spec-and-routes`); compile with `npm run build`.
+
+## Decision Gates
+
+| Situation | Decision |
+|-----------|----------|
+| Does the method take `sessionUser`? | Call `validateSessionUser` first. |
+| Does the method act on a `companyId`? | Then `validatePermissionsByCompany`. |
+| Endpoint exposed in the admin backend? | Default: `@Middlewares(authenticateMiddleware)`. |
+| Endpoint hits WhatsApp notification / public recovery / ratings or another abuse-prone path? | Consider `rateLimiter` (or `ratingRateLimiter`) from `server/src/middleware/ratelimiter.ts`. When both apply: `@Middlewares([rateLimiter, authenticateMiddleware])`. |
+| Internal/system-only endpoint? | Use `systemTokenMiddleware` instead of/with the above. |
+| Doubt about middleware, role, or method? | STOP and ask. See Ask Before Building. |
+
+## Ask Before Building (HARD — security first)
+
+STOP and ask the user BEFORE writing security or middleware code whenever there is ANY doubt. Never guess on these:
+
+1. Which validations/roles/plan features the new method requires (ADMIN vs EMPLOYEE vs extra feature gates).
+2. Whether the endpoint should be public (no `authenticateMiddleware`) or authenticated. A missing auth middleware is a security hole — when unsure, default to KEEPING `authenticateMiddleware` and confirm.
+3. Whether `rateLimiter` should be applied to a given endpoint. Do NOT add it by default; ask when the endpoint could be abuse-prone.
+4. Whether a non-POST method is genuinely needed.
+
+Ask at most a couple of focused questions, then wait. Do not proceed by assumption on security.
+
+## Execution Steps
+
+Creating a collection:
+
+1. Create `server/src/Models/<Name>/<Name>.Interface.ts` — define all params, `IX`, `IXAdapter`, `IXManager`, view/result types.
+2. Create `server/src/Models/<Name>/<Name>.Adapter.Mongoose.ts` — schema, `IXDocument`, `model()`, pure DB ops implementing `IXAdapter`.
+3. Create `server/src/Models/<Name>/<Name>.ts` — `<Name>Manager implements IXManager`; instantiate the adapter in the constructor; put business rules; call `validateSessionUser` / `validatePermissionsByCompany` at the top of each secured method; export a singleton default.
+4. Re-check Ask Before Building for any unconfirmed security requirement.
+
+Creating an endpoint:
+
+1. Create `server/src/api/<Name>/<Name>.Service.ts` — one method per action, `connect(process.env.DATABASE_CONNECTION)` then delegate to the manager singleton.
+2. Create `server/src/api/<Name>/<Name>.Controller.ts` — one controller class per `@Route`; `@Middlewares(authenticateMiddleware)` unless confirmed public; `@Post()` + `@Body()`; try/catch returning `ApiValidationError`.
+3. Apply Decision Gates (rateLimiter? system token? method?).
+4. Regenerate routes: `npm run routes` then `npm run build`.
+
+## Output Contract
+
+Return: files created, the singletons/middlewares wired, any security decision that was confirmed with the user, and whether `npm run routes` / `npm run build` were run.
+
+## References
+
+- `server/src/Models/Clients/Clients.ts`, `Clients.Interface.ts`, `Clients.Adapter.Mongoose.ts` — canonical 3-file collection example (note: Clients inlines security; do NOT copy that part).
+- `server/src/Models/Posts/Posts.ts` — modern security pattern using the shared helpers.
+- `server/src/helpers/check.ts` — `validateSessionUser`, `validatePermissionsByCompany`, `validatePermissionsByClient`.
+- `server/src/api/Clients/Clients.Controller.ts`, `Clients.Service.ts` — endpoint pattern (Controller + Service).
+- `server/src/middleware/authentication.ts`, `server/src/middleware/ratelimiter.ts` — middleware sources.
+- `server/tsoa.json`, `server/package.json` (`npm run routes`) — route generation.

+
+## Phase 5: Testing
+
+- [ ] 5.1 Create `txclient/src/Models/__tests__/NotificationPreferences.validation.test.ts` — Test Yup schemas: valid inputs pass, invalid channels rejected, timezone required, quietHours format validated, reminderRules max 5 enforced (BLOCKED: no test runner in txclient)
+- [ ] 5.2 Create `txclient/src/services/__tests__/Notifications.Service.test.ts` — Mock ApiRequest.post, verify 6 functions call correct endpoints with correct params (BLOCKED: no test runner in txclient)
+- [ ] 5.3 Create `txclient/src/Store/__tests__/NotificationPreferences.Store.test.ts` — Test store actions: setMode, updateFormData, resetForm, dirty flag transitions (BLOCKED: no test runner in txclient)
+
+## Phase 6: Cleanup (if needed)
+
+- [x] 6.1 Remove any temporary console.log statements added during development
+- [x] 6.2 Verify all TypeScript types compile without errors
+- [x] 6.3 Confirm navigation links work in all three contexts (org, client, landing)

+# Proposal: Notification System Redesign
+
+## Intent
+
+The current notification system has three critical limitations: (1) notifications are sent synchronously during appointment lifecycle operations, blocking the API response; (2) the notification-sender worker only handles today's appointments with a global delay (no per-company throttling for WhatsApp rate limits); and (3) there are no per-company or per-client notification preferences — notifications are either on or off for the entire company. This redesign decouples notification delivery from business operations into a job-based, multi-channel, policy-driven system.
+
+## Scope
+
+### In Scope
+- New `NotificationJob` model: per-notification job records with status, channel, payload, retry state
+- New `CompanyNotificationPolicy` model: org-level defaults for channels, scheduling windows, WhatsApp throttle config
+- New `ClientNotificationPreferences` model: per-client opt-in/out per channel
+- New `ClientCompanyNotificationOverride` model: per-client per-org overrides
+- Policy resolution engine: Plan limits → Org override → Client prefs → Org default → System default
+- Redesigned notification-sender worker: MongoDB polling, per-company WhatsApp throttle (8–16s), multi-channel dispatch
+- Server integration: replace inline notification calls in `Appointments` with job creation
+- Multi-channel support: WhatsApp (Baileys), Email (DonWeb), System (in-app + Socket.IO)
+
+### Out of Scope
+- SMS channel (plan feature exists but not implemented today)
+- Notification templates / content builder
+- Client-facing notification preferences UI
+- Notification analytics / delivery reports
+- Push notifications (mobile)
+- Batch notification operations (e.g., "notify all clients about holiday")
+
+## Capabilities
+
+### New Capabilities
+- `notification-jobs`: Job creation, status tracking, retry logic, and lifecycle management for notification delivery
+- `notification-policies`: Company and client notification preferences, policy resolution hierarchy, channel configuration
+- `notification-worker`: Multi-channel job processor with per-company throttling and MongoDB polling
+- `notification-integration`: Server-side hooks that create notification jobs from appointment lifecycle events
+
+### Modified Capabilities
+None — no existing specs in `openspec/specs/`.
+
+## Approach
+
+**Server (job creation):** Replace inline `NotificationsManager.send*()` calls in `Appointments.ts` with `NotificationJobService.createJob()`. The service resolves the effective policy, checks plan limits, and persists a `NotificationJob` document. This makes API calls non-blocking.
+
+**notification-sender (worker):** Poll MongoDB for `status: "pending"` jobs. Process per-company with configurable WhatsApp throttle (default 8–16s between messages for same company). Email and System channels have no throttle. Failed jobs retry up to 3x with exponential backoff.
+
+**Policy resolution:** Resolve in order: Plan feature flags → `ClientCompanyNotificationOverride` (per-client per-org) → `ClientNotificationPreferences` (client global) → `CompanyNotificationPolicy` (org default) → System defaults (all channels on).
+
+**Migration:** No data migration needed — no pending notifications exist. New models are additive.
+
+## Affected Areas
+
+| Area | Impact | Description |
+|------|--------|-------------|
+| `notification-sender/src/` | New | Complete rewrite: job polling, multi-channel dispatch, throttle |
+| `server/src/Models/Notifications/` | Modified | Add job creation service; existing adapters remain for direct sends |
+| `server/src/Models/Appointments/Appointments.ts` | Modified | Replace inline sends with job creation calls |
+| `server/src/Models/Plans/Plans.interface.ts` | Unchanged | Plan features already define channel support |
+| New: `server/src/Models/NotificationJobs/` | New | NotificationJob model + adapter |
+| New: `server/src/Models/NotificationPolicies/` | New | Company/Client policy models + resolution engine |
+| New: `notification-sender/src/Models/Jobs/` | New | Job polling model for worker |
+
+## Risks
+
+| Risk | Likelihood | Mitigation |
+|------|------------|------------|
+| WhatsApp rate limit hit during high-volume periods | High | Per-company throttle (8–16s), exponential backoff on failures |
+| Job queue grows faster than worker processes | Medium | Monitor queue depth; add alerting on backlog threshold |
+| Policy resolution adds latency to appointment creation | Low | Resolution is a simple DB query cascade; cache per-request |
+| Breaking existing notification behavior during transition | Medium | Feature flag: keep inline sends as fallback during rollout |
+
+## Rollback Plan
+
+1. Disable job creation in server via feature flag (reverts to inline sends)
+2. Stop notification-sender worker
+3. Existing inline notification paths remain unchanged — no code removal needed until stable
+4. Job collection can be truncated without data loss (jobs are ephemeral)

+// The actual public booking flow for collaborator resolution is:
+//
+//   Frontend (Appointment.tsx)
+//     → POST /employees/employees-by-service
+//       → FindEmployeesByServiceController.findEmployeesByService()
+//         → new EmployeesService().findByService(requestBody)    [thin wrapper: connect() + delegate]
+//           → EmployeesServicesList.findByService(data)          [model — tested above]
+//
+// The model layer (EmployeesServicesManager.findByService) is the GATEKEEPER
+// that applies the `removed` guard. The controller and service classes are thin
+// pass-through wrappers with no additional filtering logic.
+//
+// Full-path integration testing (controller → service → model → DB) is not
+// practically unit-testable because:
+//   1. The service layer calls mongoose.connect() which requires a real DB
+//   2. The controller instantiates the service class internally
+//   3. 5+ collections would need seeding (Employees, EmployeesServices, Users, Companies)
+//
+// The model-level tests above provide the STRONGEST feasible coverage because:
+//   - They exercise the exact `removed` guard logic (line 444 of EmployeesServices.ts)
+//   - They prove findById enrichment is skipped for removed/null employees
+//   - They prove the correct filter is applied to service assignment queries
+//   - The controller/service layers add no filtering — they are pure delegation
