# HelperLink Project Handover Notes

These notes summarize the key features, workflows, and endpoints implemented in the recent session. This serves as an immediate context guide for the next developer/AI assistant starting on this workspace.

## 🚀 Key Achievements & Features Implemented

### 1. Vendor Interview Rescheduling Workflow
* **Dedicated Vendor Reschedule Endpoint**: Registered `POST /api/vendor/interviews/{id}/reschedule` in `public/index.php` and implemented the logic in `app/Controllers/Api/Vendor/InterviewController.php`.
  * **Database History**: Inserts a tracking record into the `interview_reschedules` table with `requested_by = 'vendor'` and `status = 'pending'`, preserving the original date/time slot.
  * **Status Update**: Updates the main `interview_requests` table's status to `'rescheduled'`.
  * **Validation & Safety Checks**: 
    * Proposed times must fall within the vendor's active working hours.
    * Proposed times cannot overlap with another booking for the same helper (maid).
    * Date and time cannot be in the past.
    * Only active requests can be rescheduled (prevents rescheduling of `cancelled`, `completed`, or `rejected` requests).

### 2. Interview Availability Slots Retrieval
* **Endpoint**: `GET /api/vendor/interviews/{id}/availability`.
* **Logic**: Generates categorized 45-minute (or customized vendor duration) availability slots for the specific interview date.
* **Slot Categories**:
  * `selected`: The time slot corresponding to the interview currently being rescheduled.
  * `taken`: Slots that overlap with other confirmed interviews for the same maid.
  * `available`: Active working hour slots that are free.
* **Fallbacks**: Applies custom vendor settings from `vendor_interview_settings` and `vendor_interview_availability`. If none are configured, defaults to UAE working hours (Sun-Thu, 9 AM – 6 PM).

### 3. Interview Status Transition Upgrades
* **Endpoint**: `POST /api/vendor/interviews/{id}/status`.
* **Enhancements**: Added native backend logic and comprehensive API documentation in `API_COLLECTION.json` for the new status transitions:
  * **`confirmed`**: Activates a meeting link (auto-generated Google Meet format if empty).
  * **`rejected`**: Rejects request with optional vendor notes.
  * **`completed`**: Marks interview as conducted.
  * **`cancelled`**: Requires a pre-defined `cancel_reason` and an optional custom `cancel_message`.

### 4. Quotations Decline & Detail Views
* **Admin Dashboard Details**: Implemented detailed view capabilities for quotations on the admin panel page (`helperlink/public/admin?page=quotations`), ensuring admins can view complete quotation breakdowns.
* **Decline Workflows**: Standardized quotation decline requests in the Postman collection documentation. Decline requests require a status of `'declined'`, a mandatory `'decline_reason'`, and an optional custom `'decline_message'`.

## 🛠️ Key Files Modified

* **Controller**: `app/Controllers/Api/Vendor/InterviewController.php` (contains status transitions, availability slot generation, and the new reschedule method).
* **Routes**: `public/index.php` (registered `/availability` and `/reschedule` routes for vendor).
* **API Documentation**: `resources/docs/API_COLLECTION.json` (fully updated, syntax validated, and containing updated descriptions and mock payloads for all new endpoints).

## 📬 New & Updated Vendor Endpoints

| Method | Endpoint | Description | Payload Example |
| :--- | :--- | :--- | :--- |
| **GET** | `/api/vendor/interviews/{id}/availability` | Retrieve all availability slots categorized into `selected`, `taken`, and `available`. | None |
| **POST** | `/api/vendor/interviews/{id}/reschedule` | Propose a new date/time slot for rescheduling an interview. | `{"interview_date":"2026-06-02","time_from":"10:30:00","time_to":"11:15:00","notes":"New slot proposed"}` |
| **POST** | `/api/vendor/interviews/{id}/status` | Transition the request status (`confirmed`, `rejected`, `completed`, `cancelled`). | `{"status":"completed"}` |

## 🔍 Verification & Stability
* Verified API validity by executing comprehensive CLI integration test scenarios.
* Ensured `API_COLLECTION.json` syntax parses flawlessly and meets Postman standards.
* Database constraints and transactions are verified to prevent orphaned reschedule logs or double bookings.
