 ### PM2 Commands Reference
 
+**CRITICAL**: Every `pm2 start`, `pm2 restart`, `pm2 stop`, or `pm2 delete` command MUST be immediately followed by `pm2 save`. Without this, processes become ephemeral and will disappear on PM2 daemon restarts, server reboots, or internal reconciliation events.
+
 ```bash
-# Start/reload with environment
+# ✅ CORRECT - Start/reload with environment and save
+pm2 startOrReload ecosystem.config.cjs --env production --update-env && pm2 save
+
+# ✅ CORRECT - Restart and save
+pm2 restart flyer-crawler-api && pm2 save
+
+# ✅ CORRECT - Stop and save
+pm2 stop flyer-crawler-api && pm2 save
+
+# ✅ CORRECT - Delete and save
+pm2 delete flyer-crawler-api && pm2 save
+
+# ❌ WRONG - Missing save (processes become ephemeral)
 pm2 startOrReload ecosystem.config.cjs --env production --update-env

+**Why This Matters**: PM2 maintains an in-memory process list. The `pm2 save` command writes this list to `~/.pm2/dump.pm2`, which PM2 uses to resurrect processes after daemon restarts. Without it, your carefully managed process state is lost.

 **Purpose**: Immediately identifies cross-environment contamination.
 
+#### Layer 6: PM2 Process List Persistence
+
+**CRITICAL**: Save the PM2 process list after every state-changing operation:
+
+```bash
+# After any pm2 start/stop/restart/delete operation
+pm2 save
+
+# Example: After cleanup loop completes
+targetProcesses.forEach(p => {
+  exec('pm2 delete ' + p.pm2_env.pm_id);
+});
+exec('pm2 save');  // Persist all deletions
+```
+
+**Purpose**: Ensures PM2 process state persists across daemon restarts, server reboots, and internal reconciliation events.
+
+**Why This Matters**: PM2 maintains an in-memory process list. Without `pm2 save`, processes become ephemeral:
+
+- Daemon restart → All unsaved processes disappear
+- Server reboot → Process list reverts to last saved state
+- PM2 internal reconciliation → Unsaved processes may be lost
+
+**Pattern**: Every `pm2 start`, `pm2 restart`, `pm2 stop`, or `pm2 delete` MUST be followed by `pm2 save`.
