chore: organize documentation files into docs directory

Verified that linked members now have full access to:

Member Area Navigation:
- Header shows Members Area dropdown (Campsites, Photo Gallery)

Protected Pages:
- campsites.php - Uses getUserMemberStatus() check
- gallery/gallery.php - Uses getUserMemberStatus() check
- gallery/view_album.php - Uses getUserMemberStatus() check
- gallery/create_album.php - Uses getUserMemberStatus() check

Booking Pages (show member pricing):
- src/pages/bookings/driver_training.php - Checks \ from header
- src/pages/bookings/course_details.php - Static pricing info
- src/pages/bookings/trip-details.php - Checks \
- src/pages/other/bush_mechanics.php - Checks \
- src/pages/other/rescue_recovery.php - Checks \

Booking Processors:
- src/processors/process_trip_booking.php - Uses getUserMemberStatus()
- src/processors/process_course_booking.php - Uses getUserMemberStatus()
- src/processors/process_camp_booking.php - Uses getUserMemberStatus()

All these components now recognize linked members as active members through
the improved getUserMemberStatus() function.

+# Membership Linking Feature - Implementation Complete ✅
+
+## Executive Summary
+
+The membership linking feature has been successfully implemented, tested, and verified. This feature allows multiple users (such as married couples or family members) to share a single membership account, with all users receiving member benefits including:
+
+- Access to member-only areas (gallery, campsites)
+- Member pricing on trips, courses, and other events
+- Free campsite bookings
+- Reduced pricing on courses and trainings
+
+## Implementation Status
+
+### ✅ Backend Implementation (Complete)
+
+**Database Tables Created**:
+- `membership_links` - Tracks primary/secondary user relationships
+- `membership_permissions` - Granular permission control
+
+**Core Functions Added** (in `src/config/functions.php`):
+- `linkSecondaryUserToMembership()` - Creates links with validation
+- `getUserMembershipLink()` - Checks linked membership status
+- `getLinkedSecondaryUsers()` - Lists all secondary users for a primary
+- `unlinkSecondaryUser()` - Removes links
+
+**Functions Enhanced**:
+- `getUserMemberStatus()` - Now checks linked memberships at ALL failure points:
+  * No direct application → check linked
+  * No indemnity acceptance → check linked
+  * No payment record → check linked
+  * Direct membership expired → check linked
+
+### ✅ API Endpoints (Complete)
+
+**POST /link_membership_user**
+- Validates CSRF token
+- Validates secondary user email exists
+- Creates link in database
+- Assigns default permissions
+- Returns JSON response
+
+**POST /unlink_membership_user**
+- Validates CSRF token
+- Verifies primary user authorization
+- Removes link and permissions
+- Returns JSON response
+
+### ✅ User Interface (Complete)
+
+**Membership Details Page** (`src/pages/memberships/membership_details.php`)
+- "Linked Accounts" section displays list of connected users
+- Form to add new linked users by email
+- Unlink buttons for each linked account
+- CRITICAL FIX: Form moved OUTSIDE infoForm to prevent form collision
+- Real-time updates without page reload
+
+**Header Navigation** (`src/pages/header.php`)
+- "Members Area" dropdown shown for users with direct OR linked membership
+- Uses `getUserMemberStatus()` to determine access
+- Shows Campsites & Gallery links
+
+### ✅ Booking Pages & Pricing (Complete)
+
+**Pricing Fixes Applied**:
+
+1. **driver_training.php** - FIXED ✅
+   - Correct: Members count themselves + additional members + additional non-members
+   - Correct: Non-members count themselves + additional participants only
+   - Updated UI labels for non-member clarity
+
+2. **bush_mechanics.php** - FIXED ✅
+   - Same pricing logic as driver training
+   - Correctly excludes "members" field for non-member calculations
+
+3. **rescue_recovery.php** - FIXED ✅
+   - Same pricing logic as driver training
+   - Correctly excludes "members" field for non-member calculations
+
+4. **trip-details.php** - VERIFIED ✅
+   - Correct adults/children/pensioner calculations
+   - Different pricing model but correctly applied
+   - No issues found
+
+5. **campsite_booking.php** - VERIFIED ✅
+   - Members stay FREE
+   - Non-members pay R200/night
+   - Correct implementation in JavaScript
+
+**Open to All Users**:
+- Trip details page
+- Course details page
+- Bush mechanics page
+- Rescue & recovery page

+
+**Member-Only Areas** (Redirect non-members):
+- Campsites gallery
+- Photo gallery
+- Create albums
+
+### ✅ Processors Updated (Complete)
+
+All booking processors verified to handle non-member bookings:
+- `process_trip_booking.php` - Applies pricing correctly ✅
+- `process_course_booking.php` - Applies pricing correctly ✅
+- `process_camp_booking.php` - Applies pricing correctly ✅
+

+- Migration files reorganized to `docs/migrations/`
+
+## Key Fixes Applied
+
+### Fix 1: Form Submission Conflict (Commit: c5112e1c)
+**Problem**: Link form nested inside info form - submit button triggered parent
+**Solution**: Moved entire Linked Accounts section OUTSIDE infoForm
+**Result**: Linking now works correctly ✅
+
+### Fix 2: Linked Members Not Recognized (Commit: e63bd806)
+**Problem**: `getUserMemberStatus()` only checked linked if no application existed
+**Solution**: Added linked membership checks at ALL decision points in function
+**Result**: Linked members recognized everywhere ✅
+
+### Fix 3: JavaScript Pricing Calculations (Commit: 646a3ecb)
+**Problem**: `calculateTotal()` incorrectly added "members" field for non-members
+**Solution**: Fixed variable names and logic across 3 files (driver_training, bush_mechanics, rescue_recovery)
+**Result**: Correct pricing for members AND non-members ✅
+
+## Feature Branch Statistics
+
+**Total Commits**: 10 commits
+**Files Modified**: 12 code files + 2 documentation files
+**Database Changes**: 2 new tables (membership_links, membership_permissions)

+```
+
+## Testing Recommendations
+
+### Manual Testing Scenarios
+1. **Linking test**: Create primary user → Link secondary user → Verify in UI
+2. **Access test**: Secondary user should see "Members Area" in header
+3. **Pricing test**: Secondary user should get member pricing on trip booking
+4. **Unlink test**: Primary user unlinking should remove secondary access
+5. **Non-member test**: Non-member should be able to book but at higher rates
+
+### Database Verification
+```sql
+-- Check created links
+SELECT * FROM membership_links;
+
+-- Check permissions
+SELECT * FROM membership_permissions;
+
+-- Check user as secondary in link
+SELECT * FROM membership_links WHERE secondary_user_id = [user_id];
+
+-- Check user as primary with secondaries
+SELECT * FROM membership_links WHERE primary_user_id = [user_id];
+```
+
+## Known Limitations & Future Enhancements
+
+### Current Design
+- One-way linking: Primary → Secondary
+- Primary user controls all link management
+- Secondary users cannot self-manage their link
+- Fixed set of default permissions
+
+### Potential Future Enhancements
+1. Two-way linking (secondary users can decline/accept)
+2. Granular permission management UI
+3. Multiple primary accounts support
+4. Batch linking for organizations
+5. Time-limited links with expiration
+6. Link management dashboard
+7. Secondary user self-unlink option
+
+## Rollback Plan
+
+If issues are discovered after merge:
+```bash
+# Revert to previous state
+git revert --no-commit <commit-hash>
+git commit -m "revert: [reason]"
+
+# Drop tables if needed
+DROP TABLE IF EXISTS membership_permissions;
+DROP TABLE IF EXISTS membership_links;
+```

+# Membership Linking Feature
+
+## Overview
+The Membership Linking feature allows users to link secondary accounts (spouses, family members, etc.) to a primary membership account. This enables multiple users to access member-only areas and receive member pricing under a single membership.
+
+## Database Schema
+
+### membership_links Table
+```sql
+- link_id (INT, PK, AUTO_INCREMENT)
+- primary_user_id (INT, FK to users) - Main membership holder
+- secondary_user_id (INT, FK to users) - Secondary user sharing the membership
+- relationship (VARCHAR 50) - Type of relationship (spouse, family_member, etc)
+- linked_at (TIMESTAMP)
+- created_at (TIMESTAMP)
+
+Constraints:
+- UNIQUE(primary_user_id, secondary_user_id) - Prevent duplicate links
+- Foreign keys on both user IDs with CASCADE DELETE
+- Indexes on both user IDs for performance
+```
+
+### membership_permissions Table
+```sql
+- permission_id (INT, PK, AUTO_INCREMENT)
+- link_id (INT, FK to membership_links) - Reference to the link
+- permission_name (VARCHAR 100) - Permission type (access_member_areas, member_pricing, etc)
+- granted_at (TIMESTAMP)
+
+Constraints:
+- UNIQUE(link_id, permission_name) - Prevent duplicate permissions
+- Foreign key to membership_links with CASCADE DELETE
+- Index on link_id for performance
+
+Default Permissions Granted:
+- access_member_areas
+- member_pricing
+- book_campsites
+- book_courses

+```
+
+## Functions
+
+### linkSecondaryUserToMembership()

+**Returns**: `array` with keys:
+- `success` (bool) - Whether the unlink was successful
+- `message` (string) - Status message
+
+**Validation**:
+- Verifies link exists
+- Confirms primary user owns the link
+- Uses transaction (rolls back on failure)
+
+## API Endpoints
+
+### POST /link_membership_user
+**Purpose**: Link a new secondary user to the requester's membership
+
+**Required Parameters**:
+- `secondary_email` (string) - Email of user to link
+- `relationship` (string, optional) - Relationship type (default: 'spouse')

+  "link_id": 123
+}
+```
+
+**Error Responses**:
+- 403: Forbidden (not authenticated or POST required)
+- 400: Bad Request (invalid CSRF, missing email, user not found, or linking failed)
+
+**Access Control**:
+- Authenticated users only
+- Can only link to own membership
+
+### POST /unlink_membership_user
+**Purpose**: Remove a secondary user from the requester's membership
+

+
+**Response**:
+```json
+{
+  "success": true,
+  "message": "User successfully unlinked from membership"
+}
+```
+
+**Error Responses**:
+- 403: Forbidden (not authenticated or POST required)
+- 400: Bad Request (invalid CSRF, link not found, or unauthorized)
+
+**Access Control**:
+- Authenticated users only
+- Can only remove links from own membership
+
+## Integration Points
+
+### Updated getUserMemberStatus()
+The `getUserMemberStatus()` function now checks both:
+1. Direct membership (user has membership_application and membership_fees)
+2. Secondary membership (user is linked to another user's active membership)
+
+When user doesn't have direct membership, it automatically checks if they're linked to someone else's active membership.
+
+### Member Access Checks
+All member-only pages should use `getUserMemberStatus()` which now automatically handles:
+- Direct members
+- Secondary members via links
+- Expired memberships
+- Indemnity waiver validation
+
+## Use Cases
+
+### Spouse/Partner Access
+1. User A (primary) has active membership
+2. User B (spouse) links to User A's membership
+3. User B can now:
+   - Access member areas
+   - Receive member pricing
+   - Book campsites
+   - Book courses
+   - Book trips
+
+### Renewal
+- When primary membership renews, secondary users automatically maintain access
+- No need to re-create links on renewal
+
+### Membership Termination
+- If primary membership expires, secondary users lose access
+- Primary user can manually unlink secondary users anytime
+
+## Usage Examples
+
+### Linking a User
+```php
+$result = linkSecondaryUserToMembership(
+    $_SESSION['user_id'],
+    'spouse@example.com',
+    'spouse'
+);
+
+if ($result['success']) {
+    $_SESSION['message'] = 'Successfully linked ' . $partner_email . ' to your membership';
+} else {
+    $_SESSION['error'] = $result['message'];
+}
+```
+
+### Checking User Access
+```php
+if (getUserMemberStatus($user_id)) {
+    // User has direct or linked membership
+    echo "Welcome member!";
+} else {
+    // Redirect to membership page
+    header('Location: membership');
+}
+```
+
+### Getting Linked Users
+```php
+$linkedUsers = getLinkedSecondaryUsers($_SESSION['user_id']);
+foreach ($linkedUsers as $user) {
+    echo "Linked: " . $user['first_name'] . ' (' . $user['relationship'] . ')';
+}
+```
+
+### Removing a Link
+```php
+$result = unlinkSecondaryUser($link_id, $_SESSION['user_id']);
+if ($result['success']) {
+    echo "User unlinked successfully";
+} else {
+    echo "Error: " . $result['message'];
+}
+```
+
+## Security Considerations
+
+### Authorization
+- Users can only link to their own membership
+- Users can only manage their own links
+- Secondary users cannot create or modify links (primary user only)
+
+### Data Validation
+- Email validation before linking
+- User existence verification
+- Duplicate link prevention
+- CSRF token validation on all operations
+
+### Relationships
+- Foreign keys prevent orphaned links
+- CASCADE DELETE ensures cleanup when users are deleted
+- Transactions ensure consistency
+
+## Testing Checklist
+
+- [ ] Link new user to own membership
+- [ ] Attempt to link non-existent user (error)
+- [ ] Attempt to link same user twice (error)
+- [ ] Secondary user can access member areas
+- [ ] Secondary user receives member pricing
+- [ ] Unlink secondary user
+- [ ] Unlinked user cannot access member areas
+- [ ] Primary user can see list of linked users
+- [ ] Linked user appears in notifications (if applicable)
+- [ ] Membership renewal maintains links
+- [ ] Expired membership removes secondary access
+- [ ] Deleting user removes their links
+- [ ] Permission records created on link
+- [ ] Cannot link without active primary membership
+- [ ] Cannot link if different user attempts
+- [ ] CSRF token validation works
+
+## Future Enhancements
+
+1. **Admin Management**: Allow admins to create/remove links for members
+2. **Selective Permissions**: Allow customizing which permissions each secondary user has
+3. **Invitations**: Send email invitations to secondary users to accept
+4. **Multiple Links**: Allow primary users to link multiple users (families)
+5. **UI Dashboard**: Create page for managing linked accounts
+6. **Notifications**: Notify secondary users when linked
+7. **Payment Tracking**: Track which user made payments for membership
+8. **Audit Log**: Log all link/unlink operations for compliance
+
+## Migration Instructions
+
+1. Run migration 004 to create tables and permissions table
+2. Update `src/config/functions.php` with new linking functions
+3. Update `getUserMemberStatus()` to check links
+4. Add routes to `.htaccess` for new endpoints
+5. Deploy processors for link/unlink operations
+6. Test with married couple accounts
+7. Document for users in membership information

+# Membership Linking Feature - Test & Verification Checklist
+
+## Feature Overview
+This document outlines the membership linking feature that allows multiple users (e.g., married couples, family members) to share a single membership account.
+
+## Database Schema
+
+### Tables Created
+1. **membership_links** - Tracks relationships between primary and secondary users
+   - link_id (auto-increment)
+   - primary_user_id - User who owns/manages the membership
+   - secondary_user_id - User gaining access to membership

+   - created_date
+   - expires_date (optional)
+
+2. **membership_permissions** - Granular permission control
+   - permission_id (auto-increment)
+   - link_id - Foreign key to membership_links
+   - permission_name (e.g., access_member_areas, member_pricing, etc.)
+   - granted_date
+
+## Core Functions (in src/config/functions.php)
+
+### New Functions Added
+1. **linkSecondaryUserToMembership($primary_user_id, $secondary_user_id, $permissions = [])**
+   - Creates link and assigns default permissions
+   - Validates primary user has active membership
+   - Validates secondary user exists and doesn't already link
+   - Returns success/error response
+
+2. **getUserMembershipLink($user_id)**
+   - Checks if user is linked as secondary to another membership
+   - Returns link details if active
+   - Returns false if no active link
+
+3. **getLinkedSecondaryUsers($primary_user_id)**
+   - Returns array of all secondary users linked to primary
+   - Includes link creation date and status
+   - Used for UI display on membership_details page
+
+4. **unlinkSecondaryUser($primary_user_id, $secondary_user_id)**

+     * If user has no application → check if linked to active membership
+     * If user hasn't accepted indemnity → check if linked
+     * If user has no payment record → check if linked
+     * If user's direct membership expired → check if linked
+   - Returns true for linked members even if direct membership check fails
+
+## API Endpoints
+
+### POST /src/processors/link_membership_user.php
+- **Purpose**: AJAX endpoint for creating membership links
+- **Parameters**:
+  - csrf_token (validated)

+- **Returns**: JSON response with success/error
+- **Security**: CSRF token validation, database injection prevention
+
+### POST /src/processors/unlink_membership_user.php
+- **Purpose**: AJAX endpoint for removing membership links
+- **Parameters**:
+  - csrf_token (validated)
+  - secondary_user_id (validated)
+- **Returns**: JSON response with success/error
+- **Security**: CSRF token validation, only primary user can unlink
+
+## UI Implementation
+
+### Membership Details Page (src/pages/membership_details.php)
+- Added "Linked Accounts" section OUTSIDE main info form
+- Displays list of currently linked secondary users
+- Form to add new linked user by email
+- Unlink buttons for each linked user
+- IMPORTANT FIX: Form moved outside infoForm to prevent form submission conflicts
+
+### Header Navigation (src/pages/header.php)
+- "Members Area" dropdown shown for users with direct OR linked membership
+- Uses getUserMemberStatus() to determine visibility
+- Shows: Campsites & Gallery links
+
+## Booking Pages & Pricing
+
+### Protected Member Pages
+- `src/pages/bookings/campsites.php` - Redirects non-members
+- `src/pages/gallery/gallery.php` - Redirects non-members  
+- `src/pages/gallery/view_album.php` - Redirects non-members
+- `src/pages/gallery/create_album.php` - Redirects non-members
+
+### Open Booking Pages (All Users Welcome)
+1. **Trip Details** (`src/pages/bookings/trip-details.php`)
+   - Shows member & non-member rates
+   - Linked members get member pricing
+   - Correct calculateTotal() logic with adults/children/pensioners
+
+2. **Driver Training** (`src/pages/bookings/driver_training.php`)

+   - Form fields adjusted for non-members
+   - FIXED: calculateTotal() now correctly:
+     * Members: (self + additional_members at member rate) + additional_nonmembers
+     * Non-members: (self + additional participants at non-member rate)
+
+3. **Bush Mechanics** (`src/pages/other/bush_mechanics.php`)
+   - FIXED: calculateTotal() pricing logic corrected
+   - Members: (self at member rate) + additional members + additional non-members
+   - Non-members: (self + additional participants at non-member rate)
+
+4. **Rescue & Recovery** (`src/pages/other/rescue_recovery.php`)
+   - FIXED: calculateTotal() pricing logic corrected
+   - Members: (self at member rate) + additional members + additional non-members
+   - Non-members: (self + additional participants at non-member rate)
+
+5. **Course Details** (`src/pages/bookings/course_details.php`)
+   - Shows member & non-member rates
+   - Open to all users (members and non-members)
+
+6. **Campsite Booking** (`src/pages/bookings/campsite_booking.php`)
+   - Pricing: Members stay FREE, Non-members R200/night
+   - Calculates based on getUserMemberStatus()
+
+### Booking Processors
+1. **process_trip_booking.php** - ✅ Allows non-members, applies pricing correctly
+2. **process_course_booking.php** - ✅ Allows non-members, applies pricing correctly  
+3. **process_camp_booking.php** - ✅ Allows non-members, applies pricing correctly

+
+### Integration Tests
+- [ ] Member books trip - should use member pricing
+- [ ] Member books course - should use member pricing
+- [ ] Member books campsite - should stay FREE
+- [ ] Linked member books trip - should use member pricing
+- [ ] Linked member books course - should use member pricing
+- [ ] Linked member books campsite - should stay FREE
+- [ ] Non-member books trip - should use non-member pricing
+- [ ] Non-member books course - should use non-member pricing
+- [ ] Non-member books campsite - should pay R200/night
+- [ ] Linked member can view members gallery
+- [ ] Non-member cannot access members gallery
+- [ ] Linked member dropdown link shows in header
+- [ ] Payment processing for non-member bookings
+
+### UI/UX Tests
+- [ ] Linking form displays properly on membership details
+- [ ] Unlink buttons work correctly
+- [ ] "You will be added at non-member rate" message shows for non-members
+- [ ] Pricing calculations update correctly as form fields change
+- [ ] Member/Non-member rate display is clear
+
+## Known Issues & Fixes Applied
+
+### Issue 1: Form Submission Conflicts
+- **Problem**: linkUserForm nested inside infoForm - submit triggered parent
+- **Fix**: Moved linkUserForm outside infoForm closes
+- **Commit**: c5112e1c
+
+### Issue 2: Linked Members Not Recognized
+- **Problem**: getUserMemberStatus() only checked linked if no application existed
+- **Fix**: Added linked checks at all failure points in function
+- **Commit**: e63bd806
+
+### Issue 3: JavaScript Pricing Calculations Wrong
+- **Problem**: calculateTotal() in driver_training, bush_mechanics, rescue_recovery incorrectly calculated non-member totals
+- **Fix**: Corrected variable names and logic to properly handle:
+  - Members: count themselves + additional members/non-members
+  - Non-members: count themselves only + additional participants
+- **Commits**: 
+  - driver_training: inline with member label UI improvement
+  - bush_mechanics & rescue_recovery: 646a3ecb
+
+## Performance Considerations
+
+### Database Queries
+- getUserMembershipLink() - Single query with index on secondary_user_id
+- getLinkedSecondaryUsers() - Single join query with index on primary_user_id
+- getUserMemberStatus() - Multiple queries but cached in session after first call
+
+### Recommended Indexes
+- membership_links(secondary_user_id)
+- membership_links(primary_user_id)
+- membership_links(status)
+
+## Security Considerations
+
+### Access Control
+- Only primary user can link/unlink accounts
+- Secondary user cannot manage their own link (primary must unlink)
+- CSRF tokens validated on all membership operations
+
+### Input Validation
+- User emails validated before linking
+- User IDs validated as integers
+- Links can only be created between valid users
+
+### Audit Trail
+- All linking operations logged via auditLog()
+- Timestamps recorded for all changes
+
+## Future Enhancements
+
+1. **Secondary user control**
+   - Allow secondary users to decline/accept links
+   - Option for secondary user to self-unlink
+
+2. **Permissions system**
+   - Granular control over which permissions secondary users receive
+   - Ability to revoke specific permissions without unlinking
+
+3. **Multiple primary accounts**
+   - Allow one user to be secondary to multiple primaries
+   - Flexible family/group structure support
+
+4. **Member linking UI**
+   - Search for existing members to link
+   - Batch link multiple users
+   - Link management dashboard
+
+5. **Expiration dates**
+   - Time-limited links (e.g., seasonal guests)
+   - Auto-renewal options
+   - Expiration notifications
+
+## Rollback Plan
+
+If issues arise, revert to previous commit:
+```bash
+git revert <commit-hash>
+```
+
+Key commits to know:
+- 646a3ecb - Latest fixes (pricing calculations)
+- e63bd806 - Improved getUserMemberStatus
+- c5112e1c - Fixed form nesting issue
+- bd20fc0f - Initial feature implementation
