What changed
OpenClaw-mounted IDE terminals now use the existing same-origin HTTP/SSE realtime transport instead of the host gateway event channel. Standalone deployments continue using the raw terminal WebSocket.
Root cause
Live tracing on the reported Linux instance showed browser input dispatch in about 18 ms, while PTY output reached xterm about 1.9 seconds later. The same PTY output arrived immediately through the existing SSE endpoint, isolating the delay to OpenClaw host gateway event scheduling.
Impact
Typed characters and TUI redraws should appear in real time on OpenClaw-mounted Linux installations.
Validation
node --experimental-strip-types --test apps/web/src/features/ide-workbench/terminal/terminalTransportChain.test.mjs(9/9)npm run typecheck:webThis stays draft until the reporter verifies the branch build on the Linux instance.
