I connected Pidex's desktop workbench to actual Pi workspaces and sessions. The app could import existing session history and resume through pi --mode rpc, with prompt and steer operations going to a running local process.1
Streaming events came back through IPC into the timeline, including cards for bash, read, edit and write activity. That gave the renderer something real to present instead of a conversation-shaped mockup.
Test the round trip
The PR's Electron check expanded a workspace, resumed a session, sent a bash prompt and checked the resulting tool card and output. That was a more useful milestone than opening a window successfully.
The visual work landed alongside it: Pi-inspired tokens, fonts, panels, badges and bracket buttons, plus the hidden-inset native tab bar. But the runtime connection was the important boundary in this pass.
Pidex now depended on finding a local Pi executable, with PATH and Homebrew locations considered by the launch path. The interface and the process behind it had to agree before session resume could be treated as a working feature.
