# Demo Setup
|
||
|
||
Pre-stage checklist for the 3-minute live demo. Do this on all 3 laptops before walking on stage.
|
||
|
||
---
|
||
|
||
## Before demo day
|
||
|
||
- [ ] `demo-pod` room created in LiveKit Cloud dashboard
|
||
- [ ] Hermes deployed on DO (or confirmed running locally as fallback)
|
||
- [ ] MongoDB Atlas cluster running, `MONGODB_URI` set in Hermes env
|
||
- [ ] All `.env` vars populated and verified via `GET /health` returning `{ ok: true }`
|
||
- [ ] Record a backup video of the full demo working end-to-end
|
||
- [ ] Rehearse the demo script 3× with real audio
|

||
## Laptop setup (all 3 machines)
|
||
|
||
### Editor settings
|
||
|
||
- Font size: **18pt or larger** — Gemini Vision must read file names and code
|
||
- Single editor window — no split panes, no overlapping terminals
|
||
- File tab visible with full file name shown (not truncated)
|
||
- Light or dark theme is fine — avoid low-contrast themes
|
||
|
||
### Browser
|
||
|
||
- Chrome (best `getDisplayMedia` support)
|
||
- PWA tab open and joined to `demo-pod`
|
||
- Earbuds / headphones plugged in and tested
|
||
- Volume: medium — PodMan voice should be clearly audible but not startle
|
||
|
||
### Screen layout
|
||
|
||
- Editor takes 2/3 of screen
|
||
- Terminal takes bottom 1/3 (always visible)
|
||
- No other windows on top
|
||

||
## Demo file setup
|
||
|
||
Pre-create these files in the demo repo before the demo:
|
||
|
||
**Alice's machine:**
|
||
|
||
- Open `auth/middleware.ts` — has visible function stubs
|
||
- Terminal shows nothing running initially, then `Server running on :3001` at the right moment
|
||
|
||
**Bob's machine:**
|
||
|
||
- Open `frontend/login.tsx` — has visible form component code
|
||
- Terminal idle
|
||
|
||
**Carol's machine:**
|
||
|
||
- Open `frontend/integration.ts` or similar
|
||
- Terminal shows: `curl http://localhost:3001/auth` → `curl: (7) Failed to connect`
|
||

## Demo script timing
|
||
|
||
| Time | Action | Who |
|
||
| ----- | ----------------------------------------------- | ----------- |
|
||
| 0:00 | All three join `demo-pod` | All |
|
||
| 0:05 | PodMan greets by voice | Hermes auto |
|
||
| 0:20 | Alice opens `auth/middleware.ts`, starts typing | Alice |
|
||
| 0:45 | Bob opens `frontend/login.tsx` | Bob |
|
||
| 0:50 | Carol runs `curl` command, sees error | Carol |
|
||
| ~1:20 | BLOCKER_DETECTED nudge fires | Hermes auto |
|
||
| 1:50 | Alice starts her server (`node server.js`) | Alice |
|
||
| ~2:00 | DEPENDENCY_READY nudge fires | Hermes auto |
|
||
| 2:20 | Optional: show session 2 ownership warm-start | Presenter |
|
||
| 2:45 | Close | Presenter |
|

## Gemini Vision reliability tips
|
||
|
||
- Keep font at 18pt+ throughout the demo — do not zoom out
|
||
- Avoid opening file picker dialogs or overlapping modals during the demo
|
||
- File names in editor tabs must be fully visible (not `auth/middle...`)
|
||
- If Hermes logs show `confidence < 0.6` frames: bump font size, ensure file tab is clear
|
||
- Terminal output must be on a single line — avoid long stack traces during demo
|
||

|
||
## Cooldown note
|
||
|
||
Hermes has a 3-minute cooldown between nudges per pod. For the demo, if you need to trigger a second event quickly:
|
||
|
||
Option 1: restart Hermes between the two demo scenarios (resets cooldown state)
|
||
Option 2: set `NUDGE_COOLDOWN_MS=0` via env var during demo (add this override to Hermes)
|
||

||
|
||
## Fallback plan
|
||
|
||
If any system fails on stage:
|
||
|
||
1. **Hermes unreachable:** switch to local (`pnpm --filter backend dev`) — PWA auto-falls back to `localhost:8787`
|
||
2. **Gemini Vision low confidence:** presenter narrates what PodMan "saw" while playing the backup video
|
||
3. **LiveKit audio not working:** play backup video — show the nudge text cards on screen instead
|
||
4. **Full system failure:** play the backup recording, narrate the demo live
|
||
|
||
Always have the backup video on a separate device, not the same laptop running Hermes.
