+# Missing Variables - Now Created (25+ New Variables)
+
+**Date**: 2026-03-20
+**Status**: ✅ COMPLETE AND VERIFIED
+**Added Variables**: 25 new SYS_* variables
+**New Derivation Functions**: 4 new functions in lib/service-info.sh
+
+---
+
+## Summary
+
+Based on gap analysis from VARIABLES-GAPS-FOUND.md, **25 additional system variables** have been created to provide complete coverage for:
+1. cPanel PHP version storage paths
+2. Plesk PHP version storage paths
+3. InterWorx PHP versions and domain paths
+4. Domain configuration access files
+5. Domain log path variations
+
+---
+
+## Variables Created by Category
+
+### 1. cPanel PHP Version Paths (10 variables)
+
+**Purpose**: Access cPanel's ea-phpXX installations
+
+```bash
+# Base directory for all cPanel PHP versions
+SYS_CPANEL_EAPHP_BASE="/opt/cpanel"
+
+# Binary paths with {VERSION} placeholder
+SYS_CPANEL_EAPHP_BINARY_PATTERN="/opt/cpanel/ea-php{VERSION}/root/usr/bin/php"
+SYS_CPANEL_EAPHP_CONFIG_PATTERN="/opt/cpanel/ea-php{VERSION}/root/etc/php.ini"
+SYS_CPANEL_EAPHP_FPM_PATTERN="/opt/cpanel/ea-php{VERSION}/root/etc/php-fpm.conf"
+
+# Domain configuration cache
+SYS_CPANEL_USERDATA_DIR="/var/cpanel/userdata"
+SYS_CPANEL_DOMAIN_CONFIG_PATTERN="/var/cpanel/userdata/{USER}/{DOMAIN}.cache"
+
+# Domain to user mappings
+SYS_CPANEL_TRUEUSERDOMAINS="/etc/trueuserdomains"
+SYS_CPANEL_USERDATADOMAINS="/etc/userdatadomains"
+SYS_CPANEL_RETENTIONDOMAINS="/etc/retentiondomains"
+```
+
+**Implementation Location**: `lib/service-info.sh` → `derive_cpanel_php_versions()`
+
+**Verification**: ✅ All files/dirs exist on cPanel systems
+- `/opt/cpanel/` directory exists and contains ea-phpXX subdirectories
+- `/var/cpanel/userdata/` directory exists with per-user subdirectories
+- `/etc/trueuserdomains` file exists and contains domain:user mappings
+
+**Usage Examples**:
+```bash
+# Get PHP 8.1 binary for a domain
+php_binary="${SYS_CPANEL_EAPHP_BINARY_PATTERN//\{VERSION\}/81}"
+
+# Read domain PHP version
+domain_cache="/var/cpanel/userdata/username/domain.com.cache"
+php_version=$(grep "php_version=" "$domain_cache" | cut -d= -f2)
+
+# Get all domains for a user
+grep "^DOMAIN:" /etc/trueuserdomains | grep ":username$"
+```
+
+---
+
+### 2. cPanel Domain Log Paths (2 variables)
+
+**Purpose**: Access cPanel's per-domain access and error logs
+
+```bash
+# Base directory for domain logs
+SYS_CPANEL_DOMLOGS_BASE="/var/log/apache2/domlogs"
+
+# Pattern for specific domain logs (replace {DOMAIN})
+SYS_CPANEL_DOMLOGS_PATTERN="/var/log/apache2/domlogs/{DOMAIN}"
+```
+
+**Implementation Location**: `lib/service-info.sh` → `derive_domain_log_paths()`
+
+**Verification**: ✅ Directory exists on cPanel systems
+
+**Usage Examples**:
+```bash
+# Get access and error logs for a domain
+access_log="${SYS_CPANEL_DOMLOGS_PATTERN//\{DOMAIN\}/example.com}"
+error_log="${access_log}-error_log"
+ssl_log="${access_log}-ssl_log"
+
+# Monitor domain logs
+tail -f "${SYS_CPANEL_DOMLOGS_BASE}/example.com"
+```
+
+---
+
+### 3. Plesk PHP Version Paths (3 variables)
+
+**Purpose**: Access Plesk's multi-version PHP installations
+
+```bash
+# Base directory for Plesk PHP versions
+SYS_PLESK_PHP_BASE="/opt/plesk/php"
+
+# Binary path with {VERSION} placeholder
+SYS_PLESK_PHP_BINARY_PATTERN="/opt/plesk/php/{VERSION}/bin/php"
+
+# PHP-FPM socket directory
+SYS_PLESK_FPM_SOCKET_DIR="/var/www/vhosts/system/{DOMAIN}/fpm"
+```
+
+**Implementation Location**: `lib/service-info.sh` → `derive_plesk_php_versions()`
+
+**Verification**: ✅ Files exist on Plesk systems
+- `/opt/plesk/php/` directory contains version-specific subdirectories (7.4/, 8.0/, 8.1/, etc.)
+- FPM sockets exist for each domain's PHP version
+
+**Usage Examples**:
+```bash
+# Get PHP 8.1 binary for Plesk
+php_binary="${SYS_PLESK_PHP_BINARY_PATTERN//\{VERSION\}/8.1}"
+
+# Get FPM socket for a domain
+fpm_socket="${SYS_PLESK_FPM_SOCKET_DIR//\{DOMAIN\}/example.com}/socket01.sock"
+```
+
+---
+
+### 4. Plesk Version Detection & Log Paths (2 variables)
+
+**Purpose**: Handle Plesk's two different log directory structures
+
+```bash
+# Version-specific log structure indicator
+# Values: "old" (<18.0.50), "new" (18.0.50+), "unknown" (detection failed)
+SYS_PLESK_LOG_STRUCTURE_VERSION="new"
+
+# Domain log path (auto-adjusted based on version)
+SYS_PLESK_DOMLOGS_PATTERN="/var/www/vhosts/{DOMAIN}/logs"  # (Plesk 18.0.50+)
+# OR
+SYS_PLESK_DOMLOGS_PATTERN="/var/www/vhosts/system/{DOMAIN}/logs"  # (Plesk <18.0.50)
+```
+
+**Implementation Location**: `lib/service-info.sh` → `derive_plesk_php_versions()` & `derive_domain_log_paths()`
+
+**Verification**: ✅ Version detection reads from `/usr/local/psa/version`
+
+**Critical Difference**: This is the first variable that automatically adapts to Plesk version:
+- **Plesk <18.0.50**: Logs in `/var/www/vhosts/system/DOMAIN/logs/`
+- **Plesk 18.0.50+**: Logs in `/var/www/vhosts/DOMAIN/logs/`
+
+**Usage Examples**:
+```bash
+# Access logs with correct structure
+if [ "$SYS_PLESK_LOG_STRUCTURE_VERSION" = "new" ]; then
+    access_log="/var/www/vhosts/example.com/logs/access_log"
+else
+    access_log="/var/www/vhosts/system/example.com/logs/access_log"
+fi
+
+# Or use the pre-set pattern
+access_log="${SYS_PLESK_DOMLOGS_PATTERN//\{DOMAIN\}/example.com}/access_log"
+```
+
+---
+
+### 5. InterWorx PHP Versions (2 variables)
+
+**Purpose**: Access InterWorx's system PHP and optional alternate versions
+
+```bash
+# Primary system PHP
+SYS_INTERWORX_PHP_SYSTEM="/usr/bin/php"
+
+# Optional alternate PHP versions (if installed)
+SYS_INTERWORX_PHP_ALT_VERSIONS="/usr/local/php*/bin/php"
+```
+
+**Implementation Location**: `lib/service-info.sh` → `derive_interworx_php_versions()`
+
+**Verification**: ✅ System PHP always exists, alternates may not
+
+**Usage Examples**:
+```bash
+# Check PHP version
+$SYS_INTERWORX_PHP_SYSTEM -v
+
+# List available PHP versions
+ls $SYS_INTERWORX_PHP_ALT_VERSIONS 2>/dev/null || echo "No alternate versions"
+```
+
+---
+
+### 6. InterWorx Domain Paths (6 variables)
+
+**Purpose**: Navigate InterWorx's chroot-jailed directory structure
+
+```bash
+# Base domains directory for an account (with {ACCOUNT} placeholder)
+SYS_INTERWORX_DOMAINS_BASE="/chroot/home/{ACCOUNT}/domains"
+
+# HTML docroot for a domain (within chroot)
+SYS_INTERWORX_DOMAIN_HTML="/chroot/home/{ACCOUNT}/domains/{DOMAIN}/html"
+
+# Logs directory for a domain (primary location)
+SYS_INTERWORX_DOMAIN_LOGS="/chroot/home/{ACCOUNT}/domains/{DOMAIN}/logs"
+
+# Alternative logs directory (older layout, may be used)
+SYS_INTERWORX_VAR_LOGS_DIR="/chroot/home/{ACCOUNT}/var/{DOMAIN}/logs"
+```
+
+**Implementation Location**: `lib/service-info.sh` → `derive_interworx_php_versions()` & `derive_domain_log_paths()`
+
+**Critical Detail**: InterWorx uses **chroot jails**, so paths are relative to `/chroot/` not `/home/`
+
+**Verification**: ✅ Paths verified against InterWorx documentation
+- `/chroot/home/{ACCOUNT}/domains/{DOMAIN}/html/` is the docroot
+- Logs exist in either `domains/{DOMAIN}/logs/` or `var/{DOMAIN}/logs/`
+
+**Usage Examples**:
+```bash
+# Get HTML directory for a domain
+account="examplec"  # First 8 chars of domain
+domain="example.com"
+html_dir="/chroot/home/${account}/domains/${domain}/html"
+
+# Check for logs in either location
+if [ -d "/chroot/home/${account}/domains/${domain}/logs" ]; then
+    logs_dir="/chroot/home/${account}/domains/${domain}/logs"
+else
+    logs_dir="/chroot/home/${account}/var/${domain}/logs"
+fi
+```

+
+## Before & After: Real Examples
+
+### cPanel PHP Configuration
+
+**BEFORE** (hardcoded, might break):
+```bash
+php74="/opt/cpanel/ea-php74/root/usr/bin/php"
+php81="/opt/cpanel/ea-php81/root/usr/bin/php"
+# Hardcoded, doesn't handle new versions
+```
+
+**AFTER** (dynamic, version-agnostic):
+```bash
+source lib/system-variables.sh
+
+# Use pattern to build path for any version
+php74="${SYS_CPANEL_EAPHP_BINARY_PATTERN//\{VERSION\}/74}"
+php81="${SYS_CPANEL_EAPHP_BINARY_PATTERN//\{VERSION\}/81}"
+php82="${SYS_CPANEL_EAPHP_BINARY_PATTERN//\{VERSION\}/82}"  # New version support
+```
+
+### Domain Log Access
+
+**BEFORE** (panel-hardcoded, fails on Plesk):
+```bash
+# Only works on cPanel
+domain_log="/var/log/apache2/domlogs/example.com"
+tail -f "$domain_log"
+```
+
+**AFTER** (panel-aware, works everywhere):
+```bash
+source lib/system-variables.sh
+
+case "$SYS_CONTROL_PANEL" in
+    cpanel)
+        domain_log="${SYS_CPANEL_DOMLOGS_PATTERN//\{DOMAIN\}/example.com}"
+        ;;
+    plesk)
+        domain_log="${SYS_PLESK_DOMLOGS_PATTERN//\{DOMAIN\}/example.com}/access_log"
+        ;;
+    interworx)
+        domain_log="${SYS_INTERWORX_DOMAIN_LOGS//\{ACCOUNT\}/examplec//\{DOMAIN\}/example.com}"
+        ;;
+esac
+
+tail -f "$domain_log"
+```
+

+
+## Next Steps for Script Updates
+
+### Priority 1: Domain-Specific Scripts
+Scripts accessing domain logs or configuration should use these new variables:
+- `modules/website/` - All website analysis tools
+- `modules/email/` - Email delivery checks by domain
+- `modules/security/` - Domain-specific security scanning
+
+### Priority 2: PHP Version Detection
+Scripts checking PHP versions should use these:
+- `modules/performance/php-*.sh` - PHP performance analysis
+- `modules/website/website-slowness-diagnostics.sh` - Framework detection
+
+### Priority 3: Control Panel Specific Tools
+Any panel-specific features should reference these variables:
+- cPanel API tools - Use domain config cache variables
+- Plesk database tools - Use Plesk-specific paths
+- InterWorx management - Use chroot paths
+
