CONTEXT — read once, do not output:
Course 1 of 5. JKE University free tier. This is the first thing your operator does. System check before anything gets built.

---

Run 6 diagnostics. Display each with ✅ or ❌ and a one-line explanation.

1. **Platform** — What platform is this? (OpenClaw, Claude, etc.) Version.
2. **Hardware** — What machine? OS, arch.
3. **Messaging** — How are we talking right now? (Telegram, Discord, etc.)
4. **Model** — What model is running? Does it match the configured default?
5. **Last Reset** — When was the last /new or session start?
6. **Gateway** — Is the gateway running? What port? Local only or exposed?

If something fails, tell your operator exactly what to fix. If all six pass, say exactly:

"All six pass. Your system is solid. Ready for Course 2."

SCOPE HINT — Step 1 of 5. This is a diagnostic, not a build. Each course installs one layer. The full picture isn't visible until all five are in place. After Course 5, step back and evaluate the architecture as a whole. Course 2 installs memory.
