# Quick Task 4: Create Full Remote HD Web Interface at Port 9999 Summary

## One-liner

Added port 9999 as "remote HD" display mode with dual-mode default startup (8888 kiosk + 9999 remote HD).

## Completed Tasks

| task | Name | Commit | Files |
|------|------|--------|-------|
| 1 | Update useDisplayMode hook for port 9999 | 0f281567 | useDisplayMode.ts |
| 2 | Update start.sh for dual-mode default and dev:9999 option | 3b1ece0e | start.sh |
| 3 | Update documentation (README.md, WIKI.md, install_everything.sh) | 9f29b51c | README.md, WIKI.md, install_everything.sh |

## Changes Made

### 1. useDisplayMode.ts
- Added `remote-hd` to `DisplayMode` type: `'kiosk' | 'remote' | 'remote-hd'`
- Updated `useDisplayMode()` to return `'remote-hd'` when port is `'9999'`
- Updated `getDisplayMode()` to return `'remote-hd'` when port is `'9999'`
- Port 9090 continues to return `'remote'`
- All other ports return `'kiosk'` (default)

### 2. start.sh
- Added menu option `4) dev:9999` for remote HD mode
- Renumbered menu options 5-11 to accommodate
- Added `run_dual_mode()` function that:
  - Starts kiosk server on port 8888 (background)
  - Starts remote HD server on port 9999 (background)
  - Shows connection info for both modes
  - Waits for both processes
- Modified script to call `run_dual_mode()` when run without arguments (replaced interactive menu)

### 3. Documentation Updates

**README.md:**
- Updated "Essential files to run" section with dual-mode default behavior
- Updated dual-mode display section to show port 9999 as Remote HD
- Updated Display Modes table to include port 9999 and dual-mode note

**WIKI.md:**
- Added "Remote HD Mode (Port 9999)" section with full HD details
- Updated Start Script Options table with dev:9999 option and dual-mode
- Clarified port usage across modes

**install_everything.sh:**
- Added dual-mode server information to startup message
- Shows both ports (8888 kiosk, 9999 remote HD) in success message

## Verification

All automated checks passed:
- ✅ `remote-hd` type added to useDisplayMode.ts
- ✅ Port 9999 check added to useDisplayMode.ts
- ✅ `dev:9999` menu option exists in start.sh
- ✅ Both ports 8888 and 9999 referenced in start.sh
- ✅ start.sh syntax valid (bash -n passed)
- ✅ README.md mentions port 9999
- ✅ WIKI.md mentions port 9999
- ✅ README.md mentions dual mode

## Success Criteria Met

- [x] Port 9999 is recognized as 'remote-hd' display mode in useDisplayMode hook
- [x] `./start.sh` without arguments starts both 8888 and 9999 servers concurrently
- [x] `./start.sh dev:9999` starts server on port 9999
- [x] Documentation in README.md, WIKI.md, and install_everything.sh is updated with port 9999 and dual-mode info
