- * XC_VM — Process Manager
+ * Process Manager
  *
  * Centralizes process management: PID checking, killing, cron locks,
  * /proc filesystem inspection. Replaces scattered posix_kill(),
  * shell_exec('ps ...'), and file_exists('/proc/PID') calls.
  *
- * ---------------------------------------------------------------
- * What it replaces:
- * ---------------------------------------------------------------
- *
- *   CoreUtilities::checkCron()        → ProcessManager::acquireCronLock()
- *   CoreUtilities::isProcessRunning() → ProcessManager::isRunning()
- *   CoreUtilities::isStreamRunning()  → ProcessManager::isStreamRunning()
- *   CoreUtilities::isMonitorRunning() → ProcessManager::isNamedProcessRunning()
- *   CoreUtilities::checkPID()         → ProcessManager::checkPID()
- *   posix_kill($pid, 9)              → ProcessManager::kill()
- *
- * ---------------------------------------------------------------
  * Usage:
- * ---------------------------------------------------------------
  *
  *   // Check if a process is running
  *   if (ProcessManager::isRunning($pid)) { ... }
