-### Web-based TUI Support (HIGH)
+### Web-based TUI Support (HIGH) - IN PROGRESS
 **Feature**: Full TUI (Terminal User Interface) support inside the web browser
 
 **Goal**: Enable rich terminal UI applications (like htop, lazygit, OpenCode TUI mode) to render correctly in the browser-based terminal.
 
-**Components**:
-- [ ] xterm.js integration with full TUI support (colors, mouse, resize)
-- [ ] Proper TERM environment configuration (xterm-256color)
-- [ ] Mouse event passthrough for TUI interactions
-- [ ] Font/rendering optimization for box-drawing characters
-- [ ] Keyboard shortcut handling (Ctrl+C, Ctrl+Z, etc.)
+**Completed**:
+- [x] TERM=xterm-256color environment variable
+- [x] COLORTERM=truecolor for 24-bit color support
+- [x] ncurses-base and ncurses-term packages for terminfo database
+- [x] Locale configuration (en_US.UTF-8) for Unicode support
+- [x] Environment variables passed to deployed stacks
 
-**Technical Options**:
-1. **Upgrade ttyd** - Ensure latest version with full xterm.js features
-2. **Custom xterm.js wrapper** - More control over terminal emulation
-3. **Gotty alternative** - Consider other web terminal solutions
+**Remaining**:
+- [ ] Test TUI applications in browser (htop, lazygit, vim)
+- [ ] Verify mouse event passthrough works
+- [ ] Test box-drawing character rendering
+- [ ] Document TUI capabilities for users
+
+**Technical Notes**:
+- OpenCode uses built-in xterm.js web terminal
+- Terminal environment configured in Docker image + deployer
+- 256 colors verified working (tput colors = 256)
+- 104 xterm terminfo entries installed
 
 **Use Cases**:
 - OpenCode TUI mode in browser
