 Setup will:
 - Validate all config files
+- Write `.env` (mode 600) if API keys are set
 - Send a Telegram test message
 - Test LinkedIn + Wellfound logins
-- Auto-register cron jobs (if `OPENCLAW_GATEWAY_URL` + `OPENCLAW_GATEWAY_TOKEN` are set)

+
+PM2 is a Node.js process manager that runs the searcher and applier as proper system daemons — no SIGTERM issues, survives reboots.
+
+```bash
+# Install PM2
+npm install -g pm2
+
+# Start both jobs (searcher runs immediately + hourly; applier stopped by default)
+pm2 start ecosystem.config.cjs
+pm2 stop claw-applier   # keep applier off until you're ready
+
+# Survive reboots
+pm2 save
+pm2 startup             # follow the printed command (requires sudo)
+```
+
+**PM2 cheatsheet:**
+```bash
+pm2 list                        # show all jobs + status
+pm2 logs claw-searcher          # tail searcher logs
+pm2 logs claw-applier           # tail applier logs
+pm2 start claw-applier          # enable applier
+pm2 stop claw-applier           # pause applier
+pm2 restart claw-searcher       # restart searcher now
+```
+

+- **Applier**: `0 */6 * * *` (every 6h) — stopped by default, start when ready

-```bash
-export OPENCLAW_GATEWAY_URL=http://localhost:3000
-export OPENCLAW_GATEWAY_TOKEN=your_gateway_token
-node setup.mjs   # registers crons automatically

-Crons registered:
-- **Searcher**: `0 * * * *` (hourly), no timeout, enabled by default
-- **Applier**: `0 */6 * * *` (every 6h), no timeout, **disabled by default** — enable when ready

-**Via system cron** — add to crontab:
-```
-0 * * * * cd /path/to/claw-apply && KERNEL_API_KEY=xxx node job_searcher.mjs >> /tmp/searcher.log 2>&1
-0 */6 * * * cd /path/to/claw-apply && KERNEL_API_KEY=xxx node job_applier.mjs >> /tmp/applier.log 2>&1

 ## How it works
 
 **Search** — runs your keyword searches on LinkedIn and Wellfound, paginates through results, inline-classifies each job (Easy Apply vs external ATS), filters exclusions, deduplicates, and queues new jobs. First run searches 90 days back; subsequent runs search 2 days.
