-pm2 restart claw-searcher       # restart searcher now
+PM2 manages the processes but **does not schedule them** — scheduling is handled by system cron. This ensures a running searcher is never killed mid-run. If it's already running, the cron invocation hits the lockfile and exits immediately.
+
+Add to crontab (`crontab -e`):
+```
+0 * * * * cd /path/to/claw-apply && node job_searcher.mjs >> /tmp/claw-searcher.log 2>&1
+0 */6 * * * cd /path/to/claw-apply && node job_applier.mjs >> /tmp/claw-applier.log 2>&1
 ```
 
-Schedules (set in `ecosystem.config.cjs`):
-- **Searcher**: `0 * * * *` (hourly)
-- **Applier**: `0 */6 * * *` (every 6h) — stopped by default, start when ready
