 ### Technical Constraints
 
+**Why native Pseudoterminal, not xterm.js in a Webview:**
+Tower's WebSocket speaks a binary protocol (`0x00`/`0x01` framing). xterm.js handles this natively — it's what the browser dashboard uses. An alternative approach would embed xterm.js in a VS Code Webview, avoiding any protocol translation. However, Webview terminals have significant UX issues: keyboard shortcuts (Ctrl+C, arrows, paste) require custom passthrough, they can't appear in VS Code's native terminal panel or editor groups, they don't respect VS Code theming or focus management, and they feel like a browser embedded in an IDE. A native `Pseudoterminal` avoids all of this at the cost of a small binary adapter (~50 lines) that translates between Tower's binary protocol and VS Code's string-based API. This is a one-time implementation cost for a permanently better UX.
+
 **VS Code Pseudoterminal API:**
-- `Pseudoterminal.onDidWrite` expects UTF-8 strings, not binary — requires translation from the `0x01` data frames
-- `Pseudoterminal.handleInput` provides strings — must encode to binary `0x01` frames for Tower
+- `Pseudoterminal.onDidWrite` expects UTF-8 strings, not binary — requires a binary protocol adapter to translate from `0x01` data frames
+- `Pseudoterminal.handleInput` provides strings — adapter encodes to binary `0x01` frames for Tower
 - `Pseudoterminal.setDimensions` maps to `0x00` control frames for PTY resize
 - No native stdout capture — but irrelevant since Tower/shellper handle observation
 
-**WebSocket Binary Protocol Translation:**
+**Binary Protocol Adapter:**
+Translates between Tower's binary WebSocket protocol and VS Code's string-based Pseudoterminal API:
 - Incoming `0x01` frames: strip first byte, decode `Uint8Array` → UTF-8 string via `TextDecoder('utf-8', { stream: true })` (streaming mode required to handle multi-byte Unicode split across frames), fire to `onDidWrite`
 - Outgoing input: encode string → `Uint8Array`, prepend `0x01`, send over WebSocket
 - Control frames (`0x00`): handle resize, ping/pong, sequence numbers for replay

 **Escape sequence buffering:**
-WebSocket frames can split ANSI escape sequences mid-sequence (e.g., CSI, OSC, DCS). Writing a partial escape to `onDidWrite` corrupts terminal state (production Bugfix #630). The Pseudoterminal adapter must buffer incomplete trailing sequences and prepend them to the next frame — same logic as `dashboard/src/lib/escapeBuffer.ts`. This should be extracted into `@cluesmith/codev-api-client` as a shared utility.

This should be extracted into `@cluesmith/codev-shared` as a shared utility.
 
 **Resize deferral during replay:**
 On reconnect, the ring buffer replays potentially large scrollback. Sending a resize control frame (`0x00` with `type: 'resize'`) while replay data is being written causes garbled rendering (production Bugfix #625). The adapter must queue resize events and flush them only after the replay write completes.
