When a user selects an App card on the dashboard via the "Select UI element" picker, thread the selected Output ids to the backend (mirroring the selected_browser_ids path) and inject a per-app context block into the system prompt: each app's absolute workspace path, entry point, meta.json, and a pointer to its SKILL.md. This lets the agent edit existing apps in place from the main view (the dashboard card's Vite runtime live-reloads on save) without switching to the Apps tab.
App Builder launched from canvas chat now seeds the React template and
registers an Output row tied to the session id, so the Apps sidebar
lights up immediately. Adds a post-session-complete sync that reads
meta.json from the workspace folder and updates the Output row's name
and description, ending the 'Untitled App' problem. Also adds a stale-
approval filter to the WS replay: resolved approvals no longer
resurrect as dead cards when the user navigates back to a chat.
