---

## 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.

# Walkthrough — Alpha Readiness Hardening (ALPHA PATCH-001)

We have successfully implemented the **Alpha Readiness Hardening (ALPHA PATCH-001)**. This patch addresses the operational readiness findings by securing public access paths, validating scanner formats before database entry, and adding dynamic safeguards for missing guest phone numbers.

---

## 1. Files Created and Modified

### Files Modified
* **[MODIFY]** [MessageController.php](file:///c:/xampp/htdocs/inveetaire/app/modules/Messaging/MessageController.php) — Prevents invalid wa.me URL compilation for guests without phone numbers.
* **[MODIFY]** [preview.php](file:///c:/xampp/htdocs/inveetaire/app/views/message/preview.php) — Disables/hides WhatsApp action elements dynamically if no phone number is provided.
* **[MODIFY]** [PublicInvitationService.php](file:///c:/xampp/htdocs/inveetaire/app/modules/PublicInvitation/PublicInvitationService.php) — Hardens public page loads by enforcing `workspace_status == active` and `invitation_status == published` bounds.
* **[MODIFY]** [OperationController.php](file:///c:/xampp/htdocs/inveetaire/app/modules/Operation/OperationController.php) — Adds input regex validation (16 hexadecimal character pattern) to prevent database overhead on malformed tokens.

---

## 2. Core Workflows Implemented

### 2.1 WhatsApp Button Guard
* Guests missing a phone number will see the "WhatsApp" link disabled and grayed out in the distribution table.
* The "Send WhatsApp" action inside the message preview modal popup is hidden.
* "Copy Invitation Link" and "Preview Message" actions remain functional.
* The system suppresses URL generation to prevent invalid `https://wa.me/?text=...` configurations.

### 2.2 Public Access status check
* Ensures public pages return a generic `404 Not Found` if the workspace status is not `'active'` or the invitation status is not `'published'`, preventing early leakage of setup/draft weddings.

### 2.3 Scanner Input Format Guard
* Scanned codes are validated against `/^[0-9a-fA-F]{16}$/` before querying database records.
* Non-conforming scans trigger immediate validation errors in the scanner UI and return 404 responses for GET/POST paths without querying models.

# Walkthrough — Default Accounts & Login UI Polish (ALPHA STABILIZATION-001)

We have successfully implemented **Alpha Stabilization-001**. This patch prepares the platform for real-world Alpha testing by seeding default user accounts, hardening query logic, and polishing the login screen presentation.

---

## 1. Files Modified

* **[MODIFY]** [AuthModel.php](file:///c:/xampp/htdocs/inveetaire/app/modules/Auth/AuthModel.php) — Corrected join queries to retrieve `r.slug` as `role_name` instead of `r.name`, aligning session role snapshot comparisons.
* **[MODIFY]** [login.php](file:///c:/xampp/htdocs/inveetaire/app/views/auth/login.php) — Redesigned spacing, vertical rhythm, button heights, and added dark mode compatibility classes.
* **[NEW]** [seed_users.php](file:///c:/xampp/htdocs/inveetaire/database/seed_users.php) — Added user seeder checking existing records for idempotency.
* **[MODIFY]** [.htaccess](file:///c:/xampp/htdocs/inveetaire/.htaccess) — Excluded `/app/admin`, `/app/couple`, `/app/crew`, `/app/support` virtual paths from root forbidden rewrite block.

---

## 2. Core Workflows Implemented

### 2.1 Default Seed Accounts
Seeded accounts exist in the database with strict role assignments and status mappings:
* **Super Admin**: `admin` / `admin` (role: `Super Admin`)
* **Crew**: `crew` / `admin` (role: `Crew`)
* **Test Couple**: `test` / `test123` (role: `Couple`, workspace: `test-couple`)
The seeding is fully idempotent and provisions the missing `test-couple` workspace using the transactional `WorkspaceService::provision` pipeline.

### 2.2 Login UI Spacing & Dark Mode
* Adjusted input paddings (`py-2.5`) and button size to match.
* Cleaned up vertical spacing (`mb-1.5` standardized) and alert margin offsets (`-mb-2`).
* Added `dark:` classes (`dark:bg-slate-900`, `dark:text-slate-300`, `dark:border-slate-700`, etc.) ensuring visual consistency in light/dark system settings.

# Walkthrough — Portal Separation & Authentication Entry Points (ALPHA STABILIZATION-002)

We have successfully implemented **Alpha Stabilization-002**. This patch refines the platform entry points, introduces a minimal frontpage landing page, and isolates the operator and couple/crew portals.

---

## 1. Files Created and Modified

### New Files Created
* **[NEW]** [landing.php](file:///c:/xampp/htdocs/inveetaire/app/views/public/landing.php) — Simple, responsive landing page.
* **[NEW]** [LandingController.php](file:///c:/xampp/htdocs/inveetaire/app/modules/Auth/LandingController.php) — Serves frontpage landing or redirects active sessions.

### Files Modified
* **[MODIFY]** [AuthController.php](file:///c:/xampp/htdocs/inveetaire/app/modules/Auth/AuthController.php) — Implemented specific entry point methods and error target redirection.
* **[MODIFY]** [login.php](file:///c:/xampp/htdocs/inveetaire/app/views/auth/login.php) — Dynamized action endpoints, headings, and subheadings.

* **[MODIFY]** [public.php](file:///c:/xampp/htdocs/inveetaire/routes/public.php) — Dispatched `/` to the landing controller.

---

## 2. Core Workflows Implemented

### 2.1 Public Landing Page (`GET /`)
Serves a responsive Tailwind-styled card featuring the title, a system summary description, and clear, distinct buttons redirecting visitors to:
* **Couple Portal** (`/couple`)
* **Operator Portal** (`/admin`)

### 2.2 Reusable Portal Entry Points
Instead of duplicating templates or controllers, `AuthController` was extended to serve the unified login page dynamically by passing context parameters:
* `/admin` serves Operator login (heading: `"Platform Admin"`, action target: `POST /admin`).
* `/couple` serves Workspace login (heading: `"Welcome back"`, action target: `POST /couple`).
* CSRF protections (`CsrfMiddleware`) are fully enforced on both state-changing endpoints.
* Authenticated users are automatically routed to their role-specific dashboards.
* Login errors redirect users back to their respective portal path (`/admin` or `/couple`), preventing cross-portal leakages.

### 2.3 Legacy Path Compatibility
`GET /login` acts as a backward-compatible pathway and immediately issues a permanent `302 Redirect` targeting the workspace entry point `/couple`.

# Walkthrough — Workspace Session Context (ALPHA STABILIZATION-003)

We have successfully implemented **Alpha Stabilization-003**. This patch refines the active workspace context management, establishing the session as the single source of truth for all business modules.

---

## 1. Files Created and Modified

### Files Modified
* **[MODIFY]** [AuthModel.php](file:///c:/xampp/htdocs/inveetaire/app/modules/Auth/AuthModel.php) — Added queries `getWorkspaceById()` and `getFirstWorkspace()` to retrieve workspace details.
* **[MODIFY]** [AuthService.php](file:///c:/xampp/htdocs/inveetaire/app/modules/Auth/AuthService.php) — Updated `bindSession()` to resolve the active workspace context immediately after successful login and set session variables (`active_workspace_id`, `active_workspace_slug`, `active_workspace_name`, `active_workspace_status`) alongside the legacy compatibility `workspace_id`.
* **[MODIFY]** [InvitationController.php](file:///c:/xampp/htdocs/inveetaire/app/modules/Invitation/InvitationController.php) — Realigned to read `active_workspace_id` from the session.
* **[MODIFY]** [GuestController.php](file:///c:/xampp/htdocs/inveetaire/app/modules/Guest/GuestController.php) — Realigned to read `active_workspace_id` from the session.
* **[MODIFY]** [MessageController.php](file:///c:/xampp/htdocs/inveetaire/app/modules/Messaging/MessageController.php) — Realigned to read `active_workspace_id` from the session.
* **[MODIFY]** [OperationController.php](file:///c:/xampp/htdocs/inveetaire/app/modules/Operation/OperationController.php) — Realigned to read `active_workspace_id` from the session.

## 2. Core Workflows Implemented

### 2.1 Workspace Context Seeding
When logging in, the authentication layer evaluates the user's role and resolves the active workspace context:
* **Super Admin**: Workspace context keys are set to `null`.
* **Couple**: Resolves the workspace associated with their `users.workspace_id`.
* **Crew**: Resolves the active workspace (falls back to the first available workspace in the single-tenant Alpha phase if not explicitly defined).
* Enforces four distinct session variables: `active_workspace_id`, `active_workspace_slug`, `active_workspace_name`, and `active_workspace_status`.

### 2.2 Realigned Business Modules
All internal controllers (Invitation, Guest, Messaging, Operation/Check-in/Dashboard) have been updated to consume `active_workspace_id` from the session instead of doing secondary lookups or using unverified identifiers. No workspace slug is exposed in internal panel URLs.

### 2.3 Session Lifecycle
The active workspace context is maintained for the duration of the session and is automatically and fully cleared on logout (`Session::destroy()`).

## 3. Verification Results

All automated curl integration tests passed successfully:
```
✅ PASS: Couple login initializes active workspace context
✅ PASS: Crew login resolves to the first workspace as fallback
✅ PASS: Super Admin login sets active workspace context to NULL
```

All modified files pass syntax check (`php -l`) with zero errors.
