+## Phase 1: Foundation
+
+- [x] 1.1 Create `txclient/src/Models/NotificationPreferences.model.ts` — TypeScript interfaces: NotificationChannel, QuietHours, ReminderRule, CompanyNotificationPolicy, ClientNotificationPreferences, ClientCompanyNotificationOverride, upsert params
+- [x] 1.2 Create `txclient/src/services/Notifications.Service.ts` — 6 API functions using `ApiRequest.post<T>()`: getCompanyPolicy, upsertCompanyPolicy, getClientPreferences, upsertClientPreferences, getClientCompanyOverride, upsertClientCompanyOverride
+- [x] 1.3 Create `txclient/src/Store/NotificationPreferences.Store.ts` — Zustand store with mode, form data, dirty flag; actions: setMode, updateFormData, resetForm

+
+## Phase 2: Org Policy Page
+
+- [x] 2.1 Create `txclient/src/app/admin/(organization-profile)/org/profile/[id]/notifications/layout.tsx` — Saveable wrapper loading company policy on mount, dispatching NEED_SAVE/SAVE events
+- [x] 2.2 Create `txclient/src/app/admin/(organization-profile)/org/profile/[id]/notifications/page.tsx` — Org policy form: channel toggles (3x Switch), quiet hours (2x input time), timezone Textbox, reminder rules dynamic list (max 5) with add/remove buttons
+- [x] 2.3 Modify `txclient/src/app/components/OrganizationHeader/OrganizationHeader.tsx` — Add "Notificaciones" menu item linking to `/admin/org/profile/[id]/notifications` with NotificationsIcon
+
+## Phase 3: Client Override Page

+- [ ] 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)
+
+## Dependencies
+
+- MongoDB (shared across all modules) — already available
+- Baileys (txbot) — existing WhatsApp integration, no changes needed
+- DonWeb email API — existing integration, no changes needed
+- Socket.IO — existing in server, no changes needed
+
+## Success Criteria
+
+- [ ] Appointment creation/update/delete returns within normal latency (< 200ms)
+- [ ] WhatsApp messages for same company spaced ≥ 8s apart
+- [ ] Failed notifications retry up to 3x with exponential backoff
+- [ ] Policy resolution correctly cascades through hierarchy
+- [ ] Zero missed notifications during 24h soak test
+- [ ] notification-sender processes backlog within 5 minutes under normal load
