Bug
In the sidebar, sessions created from the web UI show a Release button alongside Close. Clicking Release appears to do nothing — a hard refresh brings the Release button right back, indicating the backend never relinquished control.
This appears to align with backend behavior: UI clients default to control mode on attach (src/server/ws-message-router.ts:58-63), so "releasing" a UI session has no meaningful effect for that client.
Expected
The Release button should not be rendered for UI-created sessions (source === "ui"). Release/Take Control only makes sense for sessions whose primary controller is an MCP/SSH client and the UI is observing.
Repro
- Create a session from the web UI.
- In the sidebar, click Release on that session.
- Hard-refresh the page — the Release button is still there; control was never released.
Suggested fix
client/src/lib/components/Sidebar.svelte:117-126 — only render the Release branch when sess.source !== "ui" (or, more generally, only show Release/Take Control controls for sessions where another client is the natural controller).
Notes
TerminalSource is defined as "ui" | "mcp" | "ssh" (src/terminal/types.ts:4).SessionListEntry.source is already exposed to the client (client/src/lib/stores/ws.ts), and the session detail line already renders ({sess.source}), so no extra plumbing is needed.
