#### [Task 10] Internal Sabit Assignment
- **Authorized**: `start` (Message 9)
- **Completed**: Yes
- **What Was Implemented**:
  - **Sabit Fleet Matching & Invariant Validation Service**:
    - Created [`SabitFleetMatchingService`](file:///c:/Users/khruk/Desktop/livHospital/app/Services/Dispatch/SabitFleetMatchingService.php):
      - Filters hospital-owned vehicles (`ownership_type = 'sabit'`) in `AVAILABLE` status.
      - Enforces passenger capacity (`passenger_seat_capacity >= passengers + companions`) and luggage capacity.
      - Accessibility invariant matching: strictly enforces `is_wheelchair_accessible == true` when wheelchair is required, and `has_child_seat == true` when child seat is requested.
      - Maintenance isolation: broken/maintenance vehicles are automatically excluded.
      - Schedule conflict avoidance with configurable safety buffer (90 minutes before and after pickup).
      - Staff driver matching: available drivers with zero schedule collisions within the buffer interval.
  - **Assignment Workflow & Atomic Execution Authority Invariants**:
    - Created [`SabitAssignmentService`](file:///c:/Users/khruk/Desktop/livHospital/app/Services/Dispatch/SabitAssignmentService.php):
      - `offerAssignment()`: Creates assignment in `OFFERED` status with configurable response SLA (default 20 minutes) without execution authority (`has_execution_authority = false`). Updates transfer to `AWAITING_ASSIGNMENT`.
      - **Notification Withholding Invariant**: Patient notifications are strictly withheld while the transfer is awaiting assignment or offered.
      - `acceptAssignment()`: Atomically grants execution authority (`has_execution_authority = true`), revokes authority from any competing assignment, updates transfer to `CONFIRMED`, and queues personalized multilingual WhatsApp notifications in `notification_outbox`.
      - `directAssignAndConfirm()`: Direct coordinator assignment granting immediate execution authority and queueing confirmation notifications.
      - `rejectAssignment()` & `revokeAssignment()`: Reverts transfer to `AWAITING_ASSIGNMENT` and records immutable events and audit logs.
  - **Interactive Sabit Assignment Livewire Component**:
    - Built [`AssignSabitModal`](file:///c:/Users/khruk/Desktop/livHospital/app/Livewire/Transfers/AssignSabitModal.php) and view [`assign-sabit-modal.blade.php`](file:///c:/Users/khruk/Desktop/livHospital/resources/views/livewire/transfers/assign-sabit-modal.blade.php):
      - Embedded directly into transfer details and operational headers.
      - Shows eligible vehicles and staff drivers with real-time capacity and accessibility badges.
      - Supports "Teklif Gönder (Send Offer with SLA)" and "Doğrudan Ata & Onayla (Direct Assign & Confirm)".
      - Interactive driver acceptance, rejection, and revocation controls with live countdown indicators.
  - **Operational Transfer Show View Update**:
    - Integrated assignment actions into [`show.blade.php`](file:///c:/Users/khruk/Desktop/livHospital/resources/views/transfers/show.blade.php).
  - **Automated Verification**:
    - Built [`InternalSabitAssignmentTest`](file:///c:/Users/khruk/Desktop/livHospital/tests/Feature/InternalSabitAssignmentTest.php) with 7 comprehensive test scenarios verifying capacity/wheelchair matching, maintenance vehicle disqualification, 90-minute conflict avoidance, notification withholding during offer, atomic execution authority on acceptance, and rollback on rejection.
- **Main Files Created / Modified**:
  - `app/Services/Dispatch/SabitFleetMatchingService.php`
  - `app/Services/Dispatch/SabitAssignmentService.php`
  - `app/Livewire/Transfers/AssignSabitModal.php`
  - `resources/views/livewire/transfers/assign-sabit-modal.blade.php`
  - `resources/views/transfers/show.blade.php`
  - `tests/Feature/InternalSabitAssignmentTest.php`
  - `PROJECT_PROGRESS.md`
- **Verification Results**:
  - `npm run build`: built in 3.27s with all assets compiled.
  - `php artisan test`: **45 passed (256 assertions)** with 100% test pass rate.

#### [Task 11] External Destek Dispatch and Company Portal
- **Authorized**: `start` (Message 10)
- **Completed**: Yes
- **What Was Implemented**:
  - **Company Referral Mechanism & SLA Service**:
    - Created [`DestekDispatchService`](file:///c:/Users/khruk/Desktop/livHospital/app/Services/Dispatch/DestekDispatchService.php):
      - `dispatchToCompany()`: Dispatches transfer to contracted transport vendor with configurable response SLA (`expires_at_utc`), proposed contract price, and status tracking.
      - **Superseding & Retraction**: Re-dispatching to another vendor atomically marks all previous pending referrals as `superseded` and records immutable audit/event logs. Coordinators can also manually retract active referrals.
      - **Tenant-Enforced Vendor Acceptance**: Requires an active external vehicle and driver affiliated specifically with the target vendor company (`company_id`). Atomically grants execution authority, confirms the transfer, and queues personalized trilingual WhatsApp notifications for patient & companions.
      - **Vendor Rejection**: Vendor dispatchers can reject referrals with a reason, transitioning referral to `rejected` and returning the transfer request to `awaiting_assignment`.
  - **External Destek Portal (`/destek-portal`)**:
    - Built [`DestekPortal`](file:///c:/Users/khruk/Desktop/livHospital/app/Livewire/Destek/DestekPortal.php) and blade view [`destek-portal.blade.php`](file:///c:/Users/khruk/Desktop/livHospital/resources/views/livewire/destek/destek-portal.blade.php):
      - **Strict Tenant Isolation**: External dispatchers can ONLY view and act upon transfers referred to their own company (`user->company_id`). Company isolation is enforced at query level and verified with cross-tenant authorization tests.
      - Live countdown indicators showing remaining SLA minutes before expiration.
      - Vendor acceptance modal enforcing vehicle and driver selection from their own active fleet.
      - Quick rejection modal capturing vendor explanation.
      - Tabbed view showing Active Dispatches, Confirmed/In-Progress Journeys, and Past History.
  - **Coordinator Dispatch Modal**:
    - Created [`DispatchDestekModal`](file:///c:/Users/khruk/Desktop/livHospital/app/Livewire/Transfers/DispatchDestekModal.php) and blade view [`dispatch-destek-modal.blade.php`](file:///c:/Users/khruk/Desktop/livHospital/resources/views/livewire/transfers/dispatch-destek-modal.blade.php):
      - Embedded into transfer detail page [`show.blade.php`](file:///c:/Users/khruk/Desktop/livHospital/resources/views/transfers/show.blade.php).
      - Allows coordinators to select vendor, set proposed contract price and custom SLA response deadline.
      - Displays live pending referrals with quick retraction buttons.
  - **Navigation & Routing**:
    - Registered route `/destek-portal` (`destek.portal`) with auth middleware and role-appropriate sidebar links.
  - **Automated Verification**:
    - Created [`ExternalDestekDispatchTest`](file:///c:/Users/khruk/Desktop/livHospital/tests/Feature/ExternalDestekDispatchTest.php) with 7 comprehensive scenarios:
      1. Coordinator dispatches transfer to company with SLA timeout.
      2. Absolute tenant isolation between external companies (Company B cannot see or accept Company A referrals).
      3. Re-dispatching supersedes previous referral and prevents late acceptance.
      4. External company acceptance confirms transfer and queues WhatsApp notifications.
      5. Company rejection keeps transfer awaiting assignment.
      6. Coordinator retraction workflow.
      7. Destek portal Livewire workflow testing.

#### [Task 12] Trip State Machine and Driver Web Workflow
- **Authorized**: `start` (Message 11)
- **Completed**: Yes
- **What Was Implemented**:
  - **Deterministic FSM Engine ([`TripStateMachineService`](file:///c:/Users/khruk/Desktop/livHospital/app/Services/Trip/TripStateMachineService.php))**:
    - `startEnRoute()`: Transitions `confirmed` $\rightarrow$ `en_route_to_pickup`. Sets driver to `on_trip`, vehicle to `busy`, creates sequence 1 `to_pickup` trip leg, records location update, immutable `TransferEvent`, and queues `transfer.en_route_to_pickup` WhatsApp alert.
    - `arriveAtPickup()`: Transitions `en_route_to_pickup` $\rightarrow$ `arrived_at_pickup`. Completes `to_pickup` leg, starts waiting grace period, logs immutable event, and queues `transfer.arrived_at_pickup` WhatsApp alert.
    - `boardPassenger()`: Transitions `arrived_at_pickup` $\rightarrow$ `passenger_onboard`. Verifies passenger & luggage counts, initiates sequence 2 `passenger_transit` leg, and logs boarding event.
    - **Critical Invariant Guard**: Once in `passenger_onboard`, standard pre-trip cancellation is strictly blocked (`allowsCancellation() === false`).
    - `arriveAtDestination()`: Transitions `passenger_onboard` $\rightarrow$ `arrived_at_destination`. Completes `passenger_transit` leg and records arrival event.
    - `completeTrip()`: Transitions `arrived_at_destination` $\rightarrow$ `completed`. Atomically releases driver and vehicle back to `available`, updates assignment to `completed`, records completion event, and queues post-trip feedback WhatsApp notification.
    - `cancelTrip()`: Pre-boarding cancellation with reason logging and resource release.
    - `reportNoShow()`: Logs contact attempts in `contact_attempts`, releases resources, sets status to `no_show`, and queues patient no-show notification.
    - `reportIncident()`: Flags `is_incident_open = true` without erasing primary physical stage, tracks whether patient is onboard, and creates `Incident` record.
    - Server-side transition validation prevents illegal status jumps (e.g. directly jumping from `confirmed` to `completed`).
  - **Driver Web Workflow Cockpit ([`DriverTripWorkflow`](file:///c:/Users/khruk/Desktop/livHospital/app/Livewire/Driver/DriverTripWorkflow.php), [`driver-trip-workflow.blade.php`](file:///c:/Users/khruk/Desktop/livHospital/resources/views/livewire/driver/driver-trip-workflow.blade.php))**:
    - Mobile-optimized single-trip cockpit at `/driver/trip/{transfer}` with large tactile action buttons tailored to each stage.
    - Real-time 6-step visual progress stepper.
    - Strict medical privacy view: Zero clinical or diagnosis data displayed; only passenger/luggage counts and special equipment badges (wheelchair, child seat, boarding assistance).
    - One-click Google Maps / Apple Maps / Yandex navigation links.
    - Geolocation auto-detection syncing browser coordinates.
    - Integrated No-Show and Incident modals.
  - **Driver Portal ([`DriverPortal`](file:///c:/Users/khruk/Desktop/livHospital/app/Livewire/Driver/DriverPortal.php), [`driver-portal.blade.php`](file:///c:/Users/khruk/Desktop/livHospital/resources/views/livewire/driver/driver-portal.blade.php))**:
    - Located at `/driver`.
    - Tabbed interface: "Aktif Görevler" (in-progress trips), "Bekleyen Teklifler" (SLA acceptance/rejection), and "Geçmiş Transferler".
    - Coordinator driver switcher for previewing on behalf of drivers.
  - **Navigation & Routing**:
    - Registered routes `driver.portal` (`/driver`) and `driver.trip` (`/driver/trip/{transfer}`).
    - Added Driver Portal link to main navigation shell with multilingual labels.
    - Embedded "Sürücü Kokpitini Aç" button on transfer detail screen.
  - **Automated Verification**:
    - Created [`TripStateMachineAndDriverWorkflowTest`](file:///c:/Users/khruk/Desktop/livHospital/tests/Feature/TripStateMachineAndDriverWorkflowTest.php) with 8 comprehensive scenarios verifying linear lifecycle, illegal jump prevention, onboard cancellation blocking, unauthorized driver denial, no-show recording, incident reporting, and full Livewire component interaction.

#### [Task 13] Incidents, Vehicle Replacement, and Sabit-to-Destek Transfer
- **Authorized**: `start` (Message 12)
- **Completed**: Yes
- **What Was Implemented**:
  - **Incident & Replacement Orchestration Engine ([`IncidentReplacementService`](file:///c:/Users/khruk/Desktop/livHospital/app/Services/Incident/IncidentReplacementService.php))**:
    - `initiateReplacement()`: Automatically triggered upon in-transit breakdown or accident. Flags `is_incident_open = true`, `is_waiting_for_replacement = true`, updates original vehicle status to `broken_down`, creates `ReplacementRequest` in `searching` status, and logs safe waypoint coordinates while preserving `passenger_onboard` primary status.
    - `dispatchSabitReplacement()`: Internal fleet replacement dispatch. Validates vehicle and driver availability, creates replacement assignment (`has_execution_authority = false`), links `replacement_dispatch` Trip Leg, and creates `PassengerHandover` record.
    - `dispatchDestekReplacement()`: Destek external vendor fallback when internal fleet is depleted or remote. Enforces vendor vehicle and driver tenant matching, records differential cost in `transfer_costs`, and creates `replacement_dispatch` Trip Leg.
    - `markReplacementArrivedAtWaypoint()`: Replacement driver arrives at roadside safe meeting point; completes `replacement_dispatch` trip leg.
    - `confirmDriverAHandover()`: Previous driver confirms passenger & luggage handover.
    - `confirmDriverBHandover()`: Replacement driver confirms receipt of passenger & luggage.
    - **Atomic Execution Authority Swap (`executeAtomicAuthoritySwap`)**:
      - Executed within a single database transaction with pessimistic row locks (`lockForUpdate()`).
      - Atomically revokes Driver A (`has_execution_authority = false`, `status = 'revoked'`, `authority_revoked_at_utc = now()`).
      - Atomically grants Driver B (`has_execution_authority = true`, `status = 'active'`, `authority_granted_at_utc = now()`).
      - Clears `is_waiting_for_replacement = false` and closes incident.
      - Creates sequence 3 `post_handover_transit` Trip Leg from safe waypoint to destination.
      - **Driver A Lockout Invariant**: Once revoked, Driver A is barred from further state changes (`403 / DomainException`).
      - **Patient Continuity Invariant**: Transfer reference number (`TR-YYYY-XXXXX`) and patient tracking tokens remain unchanged. Queues WhatsApp notification (`transfer.vehicle_replaced`) informing passenger of replacement driver and vehicle.
  - **Coordinator Incident & Replacement UI**:
    - Built [`IncidentCenter`](file:///c:/Users/khruk/Desktop/livHospital/app/Livewire/Incidents/IncidentCenter.php) at `/incidents` (`incidents.index`): Overview of all fleet incidents with active crisis vs resolved filtering, patient onboard status indicators, and integrated replacement triggers.
    - Built [`ReplacementModal`](file:///c:/Users/khruk/Desktop/livHospital/app/Livewire/Incidents/ReplacementModal.php): Sourcing cockpit supporting both Sabit fleet and Destek external vendor dispatching, safe meeting point coordinate inputs, live dual-confirmation handover tracking, and instant authority swap execution.
    - Embedded into transfer detail page (`show.blade.php`).
  - **Driver Web Workflow Updates**:
    - Added roadside handover banner and action controls in [`DriverTripWorkflow.php`](file:///c:/Users/khruk/Desktop/livHospital/app/Livewire/Driver/DriverTripWorkflow.php) and [`driver-trip-workflow.blade.php`](file:///c:/Users/khruk/Desktop/livHospital/resources/views/livewire/driver/driver-trip-workflow.blade.php):
      - Driver A controls: "📦 Yolcu & Bagajı İkame Sürücüye Devrettim"
      - Driver B controls: "📍 Buluşma Noktasına Ulaştım" and "🤝 Yolcu & Bagajı Teslim Aldım (Görevi Devral)"
  - **Automated Verification**:
    - Created [`IncidentReplacementAndHandoverTest`](file:///c:/Users/khruk/Desktop/livHospital/tests/Feature/IncidentReplacementAndHandoverTest.php) with 6 comprehensive scenarios verifying breakdown replacement initiation, Sabit dispatch, Destek fallback with cost tracking, dual-confirmation atomic authority swap, Driver A lockout, Driver B trip completion, and full Livewire interaction.

    - `ingestLocation()`: Ingests real-time coordinate pings from driver devices (`latitude`, `longitude`, `speed_kmh`, `heading`, `accuracy_meters`, `battery_percentage`, `captured_at_utc`).
    - **Sequence Verification & Stale Packet Guard**: Verifies monotonic capture timestamps against the vehicle's last recorded telemetry packet. Out-of-order packets due to mobile re-connection are flagged as `is_stale = true` without throwing errors to prevent vehicle route jitter on live maps.
    - **Active Execution Authority Guard**: Verifies driver identity and confirms the driver holds `has_execution_authority = true` on the assigned transfer; revoked drivers (e.g. Driver A post-handover) are blocked with `DomainException`.
    - **Stale Offline Tracking Detector**: `checkStaleTracking()` checks whether active transfers have received telemetry packets within the past 3 minutes, automatically toggling `is_tracking_offline`.
    - `ingestBatch()`: Ingests arrays of queued telemetry points recorded during network blackouts in chronological order.
  - **Live WebSocket Event Broadcasting ([`TransferLocationUpdated`](file:///c:/Users/khruk/Desktop/livHospital/app/Events/TransferLocationUpdated.php))**:
    - Broadcasts location telemetry packets in real time on private staff channels (`transfers.{transferId}`) and patient tracking channels (`tracking.{tokenHash}`).
  - **Mobile Telemetry API Controller ([`TelemetryController`](file:///c:/Users/khruk/Desktop/livHospital/app/Http/Controllers/Api/TelemetryController.php))**:

    - `GET /api/telemetry/transfer/{transfer}/latest`: Coordinator/public latest location & ETA retrieval endpoint.
  - **Route Calculation & Telemetry Simulator Services**:
    - Created [`OsmRoutingService`](file:///c:/Users/khruk/Desktop/livHospital/app/Services/Telemetry/OsmRoutingService.php): OSRM/OpenStreetMap routing adapter calculating realistic waypoints, step-by-step route geometry, travel distance, and ETA.
    - Created [`TelemetrySimulatorService`](file:///c:/Users/khruk/Desktop/livHospital/app/Services/Telemetry/TelemetrySimulatorService.php): Simulates real-time vehicle movement along calculated road routes for testing, demos, and end-to-end validation.
  - **Coordinator Live Fleet Map Dashboard ([`LiveFleetMap`](file:///c:/Users/khruk/Desktop/livHospital/app/Livewire/Transfers/LiveFleetMap.php), [`live-fleet-map.blade.php`](file:///c:/Users/khruk/Desktop/livHospital/resources/views/livewire/transfers/live-fleet-map.blade.php))**:
    - Interactive vector map at `/tracking/map` powered by Leaflet 1.9.4 and OpenStreetMap Carto tiles.

#### [Task 20] Operations Dashboard and Dispatch Workspace
- **Authorized**: `start` (Message 10)
- **Completed**: Yes
- **Summary**: Implemented the central operational command center for Liv Hospital coordinators and supervisors:
  1. **Real-time Operations Cockpit**:
     - Live KPI metric tiles computed dynamically via Eloquent aggregates: today's total transfers, active in-transit journeys, unassigned transfers awaiting assignment, delayed transfer warnings, active operational incidents requiring replacement/intervention, pending external Destek referrals awaiting SLA acceptance, and available sabit fleet (available vehicles and on-duty unassigned drivers).
     - Interactive KPI cards serving as 1-click filter shortcuts into the transfer matrix.
  2. **Dual-View Operational Layout**:
     - **Kanban Board**: 5 operational stages matching dispatch mental models:
       - *Atama Bekleyenler* (`draft`, `approved_pending_assignment`, `unassigned`)
       - *Onaylandı / Yola Çıktı* (`driver_assigned`, `en_route_to_pickup`)
       - *Alış Noktasında* (`arrived_at_pickup`)
       - *Yolcu Araçta* (`passenger_onboard`)
       - *Tamamlanan & Sonuçlanan* (`completed`, `cancelled`, `no_show`, `terminated`)
       - Color-coded stage badges, urgency/delay warning ribbons, incident flags, destination metadata, and direct action triggers.
     - **Tabular Data Matrix**: Responsive, sorted, paginated table with reference number, patient name, branch badge, scheduled pickup time, flight code, pickup & dropoff addresses, driver & vehicle assignment badges, execution authority, and contextual action buttons.
  3. **Live Filter Toolbar & URL State Persistence**:
     - Query-string persisted filters (`search`, `branchFilter`, `priorityFilter`, `executionFilter`, `statusFilter`, `quickFilter`, `dateFilter`, `viewMode`).
     - Quick filter tab pills: *Tümü*, *Bugün*, *Gecikenler*, *Olay Açık*, *VIP & Acil*.
     - Live auto-refresh via Livewire background polling (`wire:poll.15s`).
  4. **Role-Scoped Routing & Access Isolation**:
     - External transport company dispatchers redirected to `/destek-portal` with multi-tenant company isolation.
     - Drivers redirected to mobile/responsive `/driver` portal.
     - Coordinators scoped strictly to their assigned hospital branch; admins able to switch between all branches.
  5. **Direct Operations Interventions**:
     - 1-click medical transport review approval (`approveMedicalReview`) for coordinator sign-off directly from cards.
     - Direct jump links to transfer operations cards (`transfers.show`), live fleet tracking map (`fleet.tracking`), and transfer creation wizard (`transfers.create`).
- **Files Created/Modified**:

#### [Task 21] Costs, Reports, and Exports
- **Authorized**: `start` (Message 11)
- **Completed**: Yes
- **Summary**: Implemented the complete operational KPI reporting, multi-currency external cost tracking, invoice reconciliation, and formula-injection-safe export center:
  1. **Operational KPI Reporting (`CostAndReportService`)**:
     - **Punctuality Metric**: Accurate on-time arrival rate % with scheduled vs arrival time evaluation within 15-minute tolerance.
     - **Average Driver Pickup Waiting Time**: Precise duration in minutes between `trip.arrived_at_pickup` event and `trip.passenger_onboard` event.
     - **Destek SLA Compliance**: Tracks external partner response times against contractual expiration deadlines, measuring breach rates and average response latency.
     - **Breakdown & Incident Tracking**: Incident frequency rate and replacement completion fulfillment rate.
     - **Volume Aggregations**: Detailed counts categorized by execution type (sabit vs destek), priority (routine, urgent, vip), and operational status.
  2. **Multi-Currency External Cost Tracking & Reconciliation**:
     - **Strict Currency Isolation**: Separate, unmixed aggregate totals for TRY, EUR, and USD (`totals_by_currency`, `approved_by_currency`, `pending_by_currency`).
     - **Cost Breakdown by Category**: `base_fare`, `extra_waiting`, `toll_bridge`, `replacement_differential`, and `penalty`.
     - **Destek Invoice Reconciliation Matrix**: Cross-references agreed dispatch proposal prices against invoiced transfer costs, computing financial variance and highlighting discrepancies.
     - **Cost Approval & Addition Workflow**: Coordinators can record additional operational expenses (e.g. bridge tolls, waiting fees) and approve/contest invoices with immutable audit logging (`AuditLog::log`).
  3. **Formula-Injection-Safe Exports (OWASP CWE-1236 Defense)**:
     - All user-controlled textual cells starting with `=`, `+`, `-`, `@`, `\t`, `\r`, or `%` are automatically neutralized by prefixing with `'`.
     - Prepend UTF-8 BOM (`\xEF\xBB\xBF`) ensuring seamless rendering of Turkish and Arabic characters in Microsoft Excel.
     - Strict medical privacy guarantee: Zero clinical or diagnostic notes are ever included in export streams.
  4. **Workspace & Livewire Interface (`CostAndOperationalReports`)**:
     - Tabbed navigation: *Operasyonel KPI & Performans*, *Maliyet Takip & Mutabakat*, and *Dışa Aktarım Merkezi*.
     - Date preset quick buttons (*Bugün*, *Dün*, *Bu Hafta*, *Bu Ay*, *Geçen Ay*, *Özel Aralık*).
     - Role-scoped routing: External dispatchers redirected to `/destek-portal`, drivers redirected to `/driver`, coordinators constrained to their hospital branch.
     - Connected sidebar navigation with active indicator (`route('reports.index')`).
- **Files Created/Modified**:
  - `app/Services/Reports/CostAndReportService.php`

  - Total: **158 tests passing**.

#### [Task 22] Settings, Retention, Security, and Reliability
- **Authorized**: `start` (Message 12)
- **Completed**: Yes
- **Summary**: Implemented enterprise-grade system settings management, automated data retention and auto-purging routines, sensitive log redaction, session and rate-limiting security, and system reliability diagnostics:
  1. **Configurable Operational Parameters (`SystemSettingsService` & `SystemSettingsManager`)**:
     - Centralized, cached setting service with typed casting (`integer`, `boolean`, `string`, `json`).
     - Categorized settings: *Operasyonel Lojistik & Çağrı*, *Filo, Geofence & Canlı Konum*, *Taşeron Destek & SLA Süreleri*, *Güvenlik, Token & Erişim*, and *Veri Saklama & Otomatik Temizleme (Retention)*.
     - Protected settings management cockpit at `/settings` with strict role guards (restricted exclusively to `admin` and `supervisor`; coordinators and drivers receive 403 Forbidden).
     - Every setting modification writes an immutable audit record to `audit_logs` capturing old and new values.
  2. **Automated Data Retention & Auto-Purging (`transfers:purge-retention`)**:
     - Artisan console command: `php artisan transfers:purge-retention {--days=30} {--tokens-days=7} {--dry-run}`.
     - **GPS Telemetry Purging**: Purges raw GPS `location_updates` older than configurable threshold (default 30 days) belonging to terminal transfers (`completed`, `cancelled`, `no_show`, `terminated`).
     - **Active Journey Invariant**: Active in-transit trips (`passenger_onboard`, `en_route_to_pickup`, etc.) are strictly shielded from deletion regardless of age.
     - **Token Purging**: Purges expired tracking tokens (`expires_at_utc < now() - 7 days`) and revoked tokens.
     - **Dry-Run Simulation**: `--dry-run` flag calculates and presents an ASCII breakdown table of identifiable records without modifying database state.
     - Execution runs logged to `AuditLog` (`system.retention_purged` / `system.retention_simulated`).
  3. **Security, Privacy & Sensitive Log Redaction**:
     - **Audit Log Redaction Invariant**: `AuditLog::sanitize()` automatically sanitizes `password`, `remember_token`, `api_token`, `raw_token`, `token_hash`, `secret`, `medical_notes`, and `diagnosis` into `***REDACTED***`.
     - **Token Hashing Invariant**: `TrackingToken` generates unguessable 64-character tokens, storing strictly their SHA-256 hash in the database. Plain token values are never persisted.
     - **Security Headers Middleware (`SecurityHeadersMiddleware`)**: Automatically appends `X-Content-Type-Options: nosniff`, `X-Frame-Options: SAMEORIGIN`, `X-XSS-Protection: 1; mode=block`, `Referrer-Policy: strict-origin-when-cross-origin`, and `Permissions-Policy`.
     - **Rate Limiting Protection**: `throttle:60,1` on public tracking endpoints and rate-limited authentication to protect against credential stuffing and DoS attacks.
  4. **Reliability & System Diagnostics (`HealthCheckController`)**:
     - Enriched `/health` endpoint returning detailed JSON diagnostics: database connectivity and latency, cache functionality, queue worker status, disk storage free space (MB/GB), external integration mode (sandbox vs production), and security compliance flags.

       - Invariant architectures: Zero clinical medical privacy, deterministic linear FSM, atomic authority roadside breakdown swap, dual-carrier messaging (WhatsApp + SMS), offline-first driver telemetry spooling, ephemeral live tracking with ahead-of-time privacy windowing, and multi-currency cost reconciliation.
       - Technology stack matrix: Laravel 11, Livewire 3, Tailwind CSS v4, Flutter 3.x, SQLite/MySQL.
       - Complete prerequisite list and installation guide from scratch.
       - Database migration, seeders, queue workers, and background scheduler setup.
       - Flutter Driver App installation, test, and execution commands.
       - Pre-seeded user accounts matrix covering all 6 roles with known credentials (`AdminLiv2026!`).
       - REST and WebSocket API specifications.
       - Operational Runbooks: Highway breakdown handling, safe meeting points, handover verification, and No-Show contact workflows.
       - Clean, annotated repository directory map.
