# Walkthrough — Invitation Engine Foundation (PILOT-001)

We have successfully implemented the **Invitation Engine Foundation (PILOT-001)**. This feature enables couples to configure their display names, love story, wedding date and time, venue address, and cover asset parameters, preview the invitation using the default Klasik Putih styling layout, and publish the invitation to transition their workspace operational phase.

## 2. Core Workflows Implemented

### 2.1 Invitation Data Storage
* **Groom & Bride Names**: Persisted to `invitations.groom_display_name` and `invitations.bride_display_name`.
* **Wedding Date**: Synergized across `workspaces.wedding_date` and the primary event row.
* **Wedding Time & Venue details**: Combined and updated inside a primary wedding event row (`is_primary = 1`) in `wedding_events` table.
* **Love Story**: Persisted in `invitations.love_story`.
* **Cover Image & Hero Quote**: Stored dynamically as a JSON object inside `section_config` of `invitation_sections` for the `hero` section slug.

### 2.2 Publication state & Lifecycle Integration
* Saving status as `'published'` updates `invitations.invitation_status` to `'published'` and sets `workspaces.activated_at` to the current timestamp.
* Post-transaction, `WorkspaceService::evaluatePhase()` is triggered, automatically transitioning the workspace operational phase from `'setup'` to `'active'`.

# Walkthrough — Guest Import Engine (PILOT-002)

We have successfully implemented the **Guest Import Engine (PILOT-002)**. This feature allows couples to import guest lists from CSV and Excel (XLSX) spreadsheets. The system maps header options, performs dual duplicate validation checks (checking duplicates inside the uploaded file as well as duplicates in the database for the active workspace), generates unique cryptographically secure 16-character public guest tokens (`guest_code`), packages additional fields (Category, Seat Number, Address) in the `notes` column, and provides a clear import stats summary.

---

## 2. Core Workflows Implemented

### 2.1 File Parsing (CSV & XLSX)
* CSV: Parses delimited records with automatic delimiter detection (detects comma, semicolon, and tab delimiters).
* XLSX: Extract string references and rows using standard XML-based parsing via ZipArchive and SimpleXML to keep the framework dependency-free. Includes checks to fail gracefully with a clean exception message if ZipArchive is missing on the host.

### 2.2 Duplication & Mapping
* Pre-checks for duplicate guest names within the uploaded file itself, and against active database rows for the workspace (case-insensitive name match).
* Packs Seat Number, Category, and Address as string items inside the `guests.notes` column (e.g. `Category: Family | Seat Number: Table A`).

### 2.3 Guest Token Security
* Generates a 16-character hexadecimal secure random token (`guest_code`) using cryptographically secure random bytes (`random_bytes`), completely independent of the guest's ID or name, with a 10-iteration loop collision guard.

---

## 2. Core Workflows Implemented

### 2.1 Guest & Event Resolution
* Resolver chain matches `workspace_slug` -> `guest_token` -> `invitation` -> `assigned events`.
* Handles multi-event mappings (Holy Matrimony, Reception, etc.) dynamically.
* Falls back to all active workspace events if no explicit guest mappings exist.
* Strict tenant isolation filters all queries by the solved `workspace_id`.
* Returns clean 404 error page on invalid tokens.

### 2.2 QR Code Format
* Integrates with `api.qrserver.com` to fetch a high-quality PNG.
* Incorporates a vector SVG fallback showing the guest's code for offline development testing.
* Employs strict security: payload contains ONLY the raw `guest_token` string — no internal database IDs are leaked.

# Walkthrough — Guest Interaction Engine (PILOT-005)

We have successfully implemented the **Guest Interaction Engine (PILOT-005)**. This feature allows invited guests to submit RSVPs and Leave Wishes directly on their public invitation page without authenticating.

---

## 1. Files Created and Modified

### New Files Created
* **[NEW]** [InteractionController.php](file:///c:/xampp/htdocs/inveetaire/app/modules/Interaction/InteractionController.php) — Receives POST requests, flashes status/errors to session, and redirects to dynamic paths.

---

## 2. Core Workflows Implemented

### 2.1 RSVP Submission
* Guests select Attending or Declined.
* If attending, they select the number of guests (limited by `invited_pax` set during Guest Import).
* Submitting is idempotent; subsequent requests update the same row in `rsvps` and keep the status synced in the `guests.rsvp_status` column.

### 2.2 Wish Submission
* Allows sending congratulations wishes.
* The guest's name is automatically associated from the secure token resolving mapping, ensuring they never have to type their name or email.
* Submitting edits overwrites previous entries in the `wishes` table (no duplicate records).
