-# CLAUDE.md - HVAC Plugin Development Guide
+# CLAUDE.md
 
-**Essential guidance for Claude Code agents working on the HVAC Community Events WordPress plugin.**
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
 
-> 📚 **Complete Best Practices**: See [docs/CLAUDE-CODE-DEVELOPMENT-BEST-PRACTICES.md](docs/CLAUDE-CODE-DEVELOPMENT-BEST-PRACTICES.md) for comprehensive development guidelines.
+## Project Overview
 
-> 📊 **Current Status**: PHP 8+ Modernization (Phase 2) in progress - debugging union type compatibility on staging
+HVAC Community Events is a WordPress plugin extending The Events Calendar (TEC) suite to create a trainer community platform. It provides custom user roles (`hvac_trainer`, `hvac_master_trainer`), event management, certificate generation, venue/organizer management, and Zoho CRM integration.
 
-> ⚠️ **Interim Status**: See [docs/PHP8-MODERNIZATION-INTERIM-STATUS.md](docs/PHP8-MODERNIZATION-INTERIM-STATUS.md) for current session progress
+- **Entry Point**: `hvac-community-events.php`
+- **Core Classes**: `includes/class-*.php` (all use singleton pattern)
+- **Templates**: `templates/page-*.php`
+- **TEC Integration**: Events, venues, organizers via The Events Calendar suite
 
-## 🚀 Quick Commands
+## Commands
 
-### Deployment (Most Common)
+### Deployment
 ```bash
-# Deploy to staging (primary command)
-scripts/deploy.sh staging
-
 # Pre-deployment validation (ALWAYS run first)
 scripts/pre-deployment-check.sh
 
-# Deploy to production (ONLY when user explicitly requests)
+# Deploy to staging
+scripts/deploy.sh staging
+
+# Deploy to production (requires explicit user request and confirmation)
 scripts/deploy.sh production
 ```
 
 ### Testing
 ```bash
-# Docker Development Environment
+# Start Docker test environment
 docker compose -f tests/docker-compose.test.yml up -d
 
-# Run E2E tests against Docker environment (headless)
+# E2E tests (headless)
 HEADLESS=true BASE_URL=http://localhost:8080 node test-master-trainer-e2e.js
+HEADLESS=true BASE_URL=http://localhost:8080 node test-comprehensive-validation.js
 
-# Run E2E tests with GNOME session browser (headed)
+# E2E tests (headed - requires display)
 DISPLAY=:0 XAUTHORITY=/run/user/1000/.mutter-Xwaylandauth.U8VEB3 node test-master-trainer-e2e.js
-
-# Run comprehensive test suite
-node test-comprehensive-validation.js
-
-# Use MCP Playwright when standard Playwright fails
-# (The MCP tools handle display integration automatically)
 ```
 
-### WordPress CLI (on server)
+### WordPress CLI (on server via SSH)
 ```bash
 wp rewrite flush
 wp eval 'HVAC_Page_Manager::create_required_pages();'
+wp eval 'wp_set_password("Password123", USER_ID);'  # Reset password (more reliable than wp user update)
 ```
 
-## 🎯 Core Development Principles
+### Staging Environment
+```bash
+# SSH access
+ssh roodev@146.190.76.204
+cd /home/974670.cloudwaysapps.com/uberrxmprk/public_html
 
-### 1. **USE MCP SERVICES PROACTIVELY**
-- `mcp__sequential-thinking__sequentialthinking` for complex planning
-- `mcp__zen-mcp__codereview` with GPT-5/Qwen for validation  
-- `mcp__zen-mcp__thinkdeep` for complex investigations
-- `WebSearch` for documentation and best practices
-- **Specialized Agents**: Use agents from user's `.claude` directory for debugging, architecture, security
+# Test account (staging)
+Username: test_master | Password: TestPass123 | Role: hvac_master_trainer
+```
+
+## Architecture
+
+### Singleton Pattern (MANDATORY)
+All core classes use the singleton pattern. Never assume static methods exist:
 
-### 2. **WordPress Template Architecture (CRITICAL)**
 ```php
-// ✅ ALWAYS use singleton patterns  
+// CORRECT
 echo HVAC_Breadcrumbs::instance()->render_breadcrumbs();
+HVAC_Venues::instance()->get_venues();
 
-// ❌ NEVER assume static methods exist
-// WRONG: HVAC_Breadcrumbs::render();
+// WRONG - will fail
+HVAC_Breadcrumbs::render();
+```
 
-// ✅ MANDATORY in all templates
+### Template Requirements
+All page templates MUST include:
+```php
+<?php
+defined('ABSPATH') || exit;
 define('HVAC_IN_PAGE_TEMPLATE', true);
 get_header();
-// content here
+// ... content ...
 get_footer();
 ```
 
-### 3. **Security-First Patterns**
+### Security Patterns
 ```php
-// Always escape output
-echo esc_html($trainer_name);
-echo esc_url($profile_link);
-
-// Always sanitize input  
+// Input sanitization
 $trainer_id = absint($_POST['trainer_id']);
+$email = sanitize_email($_POST['email']);
 
-// Always verify nonces
+// Output escaping
+echo esc_html($trainer_name);
+echo esc_url($profile_url);
+
+// Nonce verification
 wp_verify_nonce($_POST['nonce'], 'hvac_action');
 
-// Role checking (NOT capabilities)
+// Role checking (use roles, not capabilities)
 $user = wp_get_current_user();
 if (!in_array('hvac_trainer', $user->roles)) {
     wp_die('Access denied');
 }
 ```

+- Master Trainer: `/master-trainer/dashboard/`, `/master-trainer/trainers/`
+- Public: `/training-login/`, `/find-a-trainer/`
 
-### 5. **Testing & Debugging Process**
-1. **Use wordpress-troubleshooter agent for systematic diagnosis**
-2. **Create comprehensive test suite with wordpress-tester agent**
-3. **Apply wordpress-code-reviewer for security validation**  
-4. **Run mandatory pre-deployment tests with wordpress-tester**
-5. **Use wordpress-deployment-engineer for staging deployment and validation**
+## Critical Warnings
+
+### NEVER Do
+- Deploy to production without explicit user request
+- Skip pre-deployment validation (`scripts/pre-deployment-check.sh`)
+- Use static method calls without verifying singleton pattern
+- Re-enable monitoring infrastructure (causes PHP segmentation faults)
+
+### Disabled Systems (DO NOT RE-ENABLE)
+The following monitoring systems are PERMANENTLY DISABLED due to causing PHP segmentation faults:
+`HVAC_Background_Jobs`, `HVAC_Health_Monitor`, `HVAC_Error_Recovery`, `HVAC_Security_Monitor`, `HVAC_Performance_Monitor`, `HVAC_Backup_Manager`, `HVAC_Cache_Optimizer`
+
+## Zoho CRM Integration
+
+Located in `includes/zoho/`. Maps WordPress data to Zoho CRM:
+- Events → Campaigns
+- Trainers → Contacts
+- Attendees → Contacts + Campaign Members
+- RSVPs → Leads + Campaign Members
+
+**Admin Page**: `/wp-admin/admin.php?page=hvac-zoho-sync`
+
+**Important**: Staging environment blocks all write operations to Zoho CRM. Only production can sync data.
+
+## Docker Test Environment
 
-### 6. **WordPress Error Detection & Site Health**
 ```bash
-# All E2E tests now include automatic WordPress error detection
-# Tests will fail fast if critical WordPress errors are detected:
-# - Fatal PHP errors (memory, syntax, undefined functions)
-# - Database connection errors
-# - Maintenance mode
-# - Plugin/theme fatal errors
-# - HTTP 500+ server errors
-
-# If test fails with "WordPress site has critical errors":
-# 1. Restore staging from production backup
-# 2. Re-seed test data to staging:
-bin/seed-comprehensive-events.sh
-# 3. Re-run tests
-```

+### TEC Community Events Dependency
+The plugin still relies on "The Events Calendar: Community" (TEC CE) for event creation/editing forms via `[tribe_community_events]` shortcode. While `HVAC_Event_Manager` has custom CRUD capabilities, production code paths use TEC CE.
+
+**Removal estimate:** 9-14 days of development work.
+**Details:** See [docs/reports/TEC-COMMUNITY-EVENTS-DEPENDENCY-ANALYSIS.md](docs/reports/TEC-COMMUNITY-EVENTS-DEPENDENCY-ANALYSIS.md)

+# Multi-Agent, Multi-Model Code Review Report
+
+**Plugin:** HVAC Community Events WordPress Plugin
+**Date:** 2026-01-31
+**Models Used:** GPT-5 (Codex), Gemini 3, Kimi K2.5, Zen MCP (secaudit, analyze, codereview)
+**Files Reviewed:** 11 critical components (~9,000 lines)
+
+---
+
+## Executive Summary
+
+**Overall Security Posture: MODERATE**
+
+The HVAC Community Events plugin demonstrates solid security foundations with centralized security helpers, proper nonce verification, prepared SQL statements, and well-designed certificate download security. However, several issues require attention, particularly in sensitive data handling and cryptographic key management.
+
+**Context:** This is a small local WordPress environment with a single user. Security and scalability concerns are appropriately deprioritized in favor of functionality and maintainability. Findings are rated with this context in mind.

+
+### VALIDATED AS NON-ISSUES
+
+| Original Concern | Status | Reason |
+|------------------|--------|--------|
+| Path traversal in certificate downloads | **NOT EXPLOITABLE** | Token-based system stores file_path in transients, not user input |
+| SQL injection in `compile_trainer_stats()` | **SECURE** | Proper `$wpdb->prepare()` usage confirmed |
+| OAuth state CSRF protection | **PROPERLY IMPLEMENTED** | Uses `hash_equals()` with single-use tokens |
+
+---
+
+## OWASP Top 10 Mapping
+
+| Category | Status | Key Issues |
+|----------|--------|------------|
+| A01 - Broken Access Control | SECURE | Minor: roles as capabilities |
+| A02 - Cryptographic Failures | **VULNERABLE** | C1 (passwords), C2 (key storage), U5 (no MAC) |
+| A03 - Injection | SECURE | Prepared statements throughout |
+| A04 - Insecure Design | Minor | U1 (O(n) loop) |

+| A08 - Software/Data Integrity | Minor | M2 (token race) |
+| A09 - Logging Failures | Minor | U6 (log injection), U10 (PII in logs) |
+| A10 - SSRF | SECURE | |
+
+---
+
+## Positive Security Patterns Identified
+
+All models identified strong security practices:
+
+1. **Centralized AJAX Security** - `HVAC_Ajax_Security::verify_ajax_request()` enforces login + nonce + capability
+2. **Consistent Input Sanitization** - `sanitize_text_field()`, `absint()`, `wp_kses_post()` throughout
+3. **Prepared SQL Statements** - `$wpdb->prepare()` with proper placeholders
+4. **Certificate Download Security** - Time-limited, random tokens with one-time-use
+5. **OAuth CSRF Protection** - Timing-safe `hash_equals()` comparison
+6. **Comprehensive Audit Logging** - Security events logged with 30-day retention
+7. **WordPress Native Password Functions** - No custom password hashing
+8. **Modern PHP 8+ Features** - Strict types, generators, match expressions

+
+## Code Fixes Reference
+
+### Fix C1: Password Transient Storage
+
+```php
+// File: class-hvac-registration.php, around line 98
+$submitted_data = $_POST;
+// ADD THESE LINES:
+unset(
+    $submitted_data['user_pass'],
+    $submitted_data['confirm_password'],
+    $submitted_data['current_password'],
+    $submitted_data['new_password'],
+    $submitted_data['hvac_registration_nonce']
+);
+```
+
+### Fix U1: O(1) Token Verification
+
+```php
+// File: class-hvac-ajax-security.php, replace lines 498-513
+public static function generate_secure_token($action, $user_id) {
+    $ts = time();
+    $salt = wp_salt('auth');
+    $sig = hash_hmac('sha256', $action . '|' . $user_id . '|' . $ts, $salt);
+    return $ts . '.' . $sig;
+}
+
+public static function verify_secure_token($token, $action, $user_id, $expiry = 3600) {
+    $parts = explode('.', $token, 2);
+    if (count($parts) !== 2) return false;
+
+    [$ts, $sig] = $parts;
+    $ts = (int) $ts;
+
+    if (!$ts || empty($sig) || (time() - $ts) > $expiry) {
+        return false;

+
+    $expected = hash_hmac('sha256', $action . '|' . $user_id . '|' . $ts, wp_salt('auth'));
+    return hash_equals($expected, $sig);
+}
+```
+
+### Fix U2: Targeted Hook Removal
+
+```php
+// File: class-hvac-plugin.php, around line 1052
+// REPLACE:
+remove_all_actions('template_redirect', 10);
+
+// WITH:
+// Remove only specific HVAC auth callbacks that block registration
+remove_action('template_redirect', [$this, 'hvac_auth_redirect'], 10);
+// Or use early-return guard in the auth callback itself
+```
+
+### Fix C2: Encryption Key in wp-config.php
+
+```php
+// Add to wp-config.php:
+define('HVAC_ENCRYPTION_KEY', base64_encode(random_bytes(32)));
+
+// Modify class-hvac-secure-storage.php lines 30-40:
+private static function get_encryption_key() {
+    if (!defined('HVAC_ENCRYPTION_KEY')) {
+        // Fallback for migration - log warning
+        error_log('HVAC: HVAC_ENCRYPTION_KEY not defined in wp-config.php');
+        $key = get_option('hvac_encryption_key');
+        if (!$key) {
+            $key = base64_encode(random_bytes(32));
+            update_option('hvac_encryption_key', $key);
+        }
+        return base64_decode($key);
+    }

+**Objective:** Add CAPTCHA to all user-facing forms to prevent spam and bot submissions.
+
+**Forms to Update:**
+- Training login form
+- Trainer registration form
+- Contact forms (trainer, venue)
+- Any other public-facing forms
+
+---
+
+## CURRENT SESSION - SLACK NOTIFICATIONS (Feb 20, 2026)
+
+### Status: COMPLETE - Deployed to Production
+
+**Objective:** Add Slack notifications for trainer registrations, ticket purchases, and event submissions/publishes via Incoming Webhook with Block Kit rich formatting.
+
+### Features
+- **New Trainer Registration** — name, role, organization, business type, profile photo, "View in WordPress" button
+- **Ticket Purchase** — purchaser, email, event, ticket count, total, payment gateway, "View Order" button
+- **Event Submitted by Trainer** — event title, trainer, date, venue, "View Event" button
+- **Event Published by Admin** — same fields, "View Event" + "Edit in WP" buttons
+- **Settings UI** — Webhook URL field (password type), "Send Test Notification" button with AJAX feedback
+- **Test message** includes environment (Staging/Production) and site URL
+
+### Design Decisions
+- Non-blocking `wp_remote_post` for all real notifications; blocking only for test button
+- Atomic `add_post_meta(..., true)` for idempotency (prevents races and duplicate sends)
+- Webhook URL validated at save-time and send-time: `https` + `hooks.slack.com` + `/services/` path
+- Graceful degradation: empty webhook = disabled, missing meta = "N/A" fields, no exceptions surface to users
+- Code reviewed by GPT-5 (Codex) — all 5 findings fixed before production deploy
+
+### Files Modified
+
+| File | Change |
+|------|--------|

+## PREVIOUS SESSION - MARKER VISIBILITY TOGGLE CHECKBOX REFACTOR (Feb 9, 2026)
+
+### Status: COMPLETE - Deployed to Production (v2.2.18)
+
+**Objective:** Refactor the marker visibility toggles on the Find Training page from standalone colored dots into inline checkboxes beside each category tab heading.
+
+### Changes Made
+
+1. **Inline Checkboxes in Tab Buttons** (`templates/page-find-training.php`)
+   - Removed standalone `hvac-visibility-toggles` div with 3 colored dot toggles
+   - Moved each checkbox inline into its corresponding tab button (`Events`, `Trainers`, `Venues`)
+   - `onclick="event.stopPropagation()"` on labels prevents checkbox clicks from triggering tab switches
+   - Checkbox IDs unchanged — no JS changes needed
+
+2. **Custom Checkbox Styling** (`assets/css/find-training-map.css`)
+   - 14x14px custom checkboxes with category-specific fill colors when checked
+   - Trainer checkbox uses explicit `#6aad1e` (CSS variable `--hvac-trainer-color` is too light)
+   - Tablet: 12px checkboxes; Mobile (<768px): hidden
+
+3. **Version Bump** (`includes/class-hvac-plugin.php`) — `2.2.17` → `2.2.18`
+
+### Files Modified
+
+| File | Change |
+|------|--------|
+| `templates/page-find-training.php` | Removed visibility toggles div, added inline checkboxes in tab buttons |
+| `assets/css/find-training-map.css` | Replaced dot toggle CSS with checkbox styles, responsive adjustments |
+| `includes/class-hvac-plugin.php` | Version bump `2.2.17` → `2.2.18` |

+
+## PREVIOUS SESSIONS (Reverse Chronological)
+
+### Find Training Tab Reorder, Marker Highlighting & Map Reset — Feb 9, 2026 (v2.2.17)
+Reordered tabs to Events first (default), added marker highlighting on tab switch (larger/brighter icons, zIndex 100), added map reset button, fixed mobile overflow from long event titles. `9dbe472c`
+
+### Mobile Find Training Scroll Fix — Feb 9, 2026 (v2.2.14)
+Fixed mobile scrolling: switched from fixed-viewport (`100vh; overflow: hidden`) to natural page scrolling on screens ≤991px. Sticky filter bar. `4104c806`
+
+### Map Tile Drift Fix & Event Cost Display — Feb 9, 2026 (v2.2.13)
+Fixed Google Maps tile/marker drift at zoom 1-2 by setting `minZoom: 3`. Fixed event cost HTML entities (`&#x24;50` → `$50`) via `html_entity_decode()`. `f123c7a5`
+
+### Zoho CRM Sync Production Fix — Feb 6, 2026 (v2.2.11)
+Fixed silent sync failure: search criteria not sent to Zoho API (GET ignores `$data`), error reporting priority, phone validation, Last_Name fallback. Result: 64/64 trainers syncing. `4c22b9db`
+
+### Zoho CRM Sync Architecture Fix — Feb 6, 2026
+Fixed "silent failure" architecture: added `validate_api_response()`, hash-only-on-success for all 5 sync methods, staging mode detection via hostname parsing, admin hash reset button. `03b9bce5`
+
+### Near Me Button Mobile Fix — Feb 6, 2026
+Fixed `.hvac-btn-text` wrapper missing from Near Me button state changes (5 locations). Added empty results notification for Near Me filter.
+
+### Champion Differentiation on Find Training — Feb 2, 2026
+Added `is_champion` flag, distinct white-outline marker icon, non-clickable sidebar cards (state only), sorted to end of list. 18 champions differentiated from trainers.
+
+### Tabbed Interface for Find Training — Feb 1, 2026
+Refactored sidebar from single trainer list to Trainers | Venues | Events tabs with ARIA accessibility, venue/event cards, info modal, context-aware search, visibility toggle dots.
+
+### measureQuick Approved Training Labs — Feb 1, 2026
+Created venue taxonomies (`venue_type`, `venue_equipment`, `venue_amenities`), configured 9 approved labs, filtered map data by taxonomy, enhanced venue modal with equipment/amenities badges and contact form.
+
+### Find Training Page Enhancements — Feb 1, 2026
+Added viewport sync (sidebar shows only visible-in-map trainers), marker hover info windows, legacy URL redirects (`/find-a-trainer/` → `/find-training/`).
+
+### Find Training Page Implementation — Jan 31–Feb 1, 2026
+Built `/find-training` from scratch with Google Maps API replacing buggy MapGeo. 8 new files. Features: markers, clustering, filters, geolocation, modals, contact form, auto-geocoding. Multi-model code review fixed 6 issues (1 critical, 1 high).
+
+### E2E Testing & Bug Fixes — Feb 1, 2026
+Deployed 12 security fixes, ran E2E tests, fixed empty trainers table (SQL rewrite) and blank event pages (template path mismatch). Added staging email filter.
+
+### Multi-Model Security Code Review — Jan 31, 2026
+4-model review (GPT-5, Gemini 3, Kimi K2.5, Zen MCP) across 11 files. Found and fixed 12 issues: 2 critical (password transients, O(3600) DoS loop), 4 high, 4 medium, 2 low.
+
+### Master Trainer Profile Edit Enhancement — Jan 9, 2026
+Fixed button styling, added all 6 profile field sections, added password reset button with AJAX handler.
+
+### TEC Community Events Dependency Analysis — Jan 5, 2026
+Plugin still relies on TEC CE for event creation. Removal estimated 9-14 days. Deferred as technical debt.
+
+### Zoho Scheduled Sync, Batch Sync, Attendee Sync — Dec 17-20, 2025
+WP-Cron scheduled sync with configurable intervals, batch pagination with progress bar, attendee/RSVP sync to Zoho Contacts + Campaign Members. 64/64 trainers, 50/50 attendees syncing.
+
+### Earlier Sessions (Nov-Dec 2025)
+Nonce fix (v2.1.7), technical debt cleanup (v2.1.6), z-index fix (v2.1.5), Gemini environment setup, PHP 8+ compatibility, nav dropdown fix, MapGeo interceptor strategy.
