[CRITICAL_DESIGN_RULES]
# DO NOT BREAK THESE - Latest standards as of 2025-11-07

bash_strict_mode: "set -eo pipefail" (NOT -euo - -u is too strict)
cancel_buttons: MANDATORY - Every menu must have "0) Cancel", every input must accept "0"
grep_pattern: Always add "|| true" to grep/find that might not match
unbound_vars: Use ${var:-} or ${var:-default} for potentially unbound variables
arithmetic: Use current=$((current + 1)) NOT ((current++))
output_suppression: NEVER use { } >/dev/null on critical functions (breaks variable assignment)
module_isolation: Modules run in subshells with cleared SYS_* environment
press_enter: ALWAYS call press_enter at end of scripts before exit
messaging: Use print_success, print_error, print_warning, print_info (NOT echo)

[CANCEL_BUTTON_STANDARD]
# MANDATORY as of 2025-11-07 - ALL scripts must support cancellation

menu_format: |
  echo "  1) Option One"
  echo "  2) Option Two"
  echo "  0) Cancel and return to menu"    # REQUIRED
  echo ""
  read -p "Select option: " choice
  
  case $choice in
      0)
          echo "Operation cancelled."
          press_enter
          exit 0
          ;;
      # ... other options
  esac

text_input_format: |
  echo -n "Enter value (or 0 to cancel): "
  read -r value
  
  if [ -z "$value" ] || [ "$value" = "0" ]; then
      echo "Operation cancelled."
      press_enter
      exit 0
  fi

rationale: Users must NEVER be trapped in a prompt - always provide escape route

  6: Commit to git

mandatory_checklist:
  - [ ] Cancel option on ALL menus ("0) Cancel")
  - [ ] Cancel option on ALL text inputs ("or 0 to cancel")
  - [ ] press_enter() at end before exit
  - [ ] Use print_* functions (not echo for status)
  - [ ] Correct SCRIPT_DIR path resolution
  - [ ] Root check if needed
  - [ ] Error handling with proper exit codes
  - [ ] Test with bash -n (syntax check)

[WORDPRESS_CRON_MANAGER]
# New feature added 2025-11-07

location: modules/website/wordpress/wordpress-cron-manager.sh
purpose: Convert WordPress wp-cron to real system cron jobs

features:
  - Scan for all WordPress installations
  - Disable wp-cron per domain/user/server-wide
  - Add staggered system cron jobs (load distribution)
  - Revert to wp-cron
  - Check status

staggered_timing:
  purpose: Distribute cron load across 15-minute window
  pattern: Site 1=0,15,30,45 | Site 2=1,16,31,46 | Site 3=2,17,32,47
  formula: minute = (offset % 15), offset increments per site
  result: 300 sites = 20 sites per minute (manageable load)

wp-config_modification:
  function: disable_wpcron_in_config()
  location: Line 2 after <?php tag
  adds: define('DISABLE_WP_CRON', true);
  safety: Backup created, verification, rollback on failure
  format: User crontabs (crontab -u $user) not system crontab

cron_job_format: |
  0,15,30,45 * * * * cd /home/user/public_html && /usr/bin/php -q wp-cron.php >/dev/null 2>&1

options:
  1: Scan for WordPress installations
  2: Disable wp-cron for specific domain
  3: Disable wp-cron for specific user (all their WP sites)
  4: Disable wp-cron server-wide (all WordPress sites)
  5: Check wp-cron status
  6: Re-enable wp-cron for specific domain
  7: Re-enable wp-cron for specific user
  8: Re-enable wp-cron server-wide
  0: Return to menu (cancel)
