Follow-ups promised on merge, plus review findings on the batch itself: - chat: task-tool output now respects the 512KiB render cap; quick-open icon is visible at rest on coarse pointers and reachable by keyboard (row keydown no longer swallows inner-button Enter/Space); composer inline-code decoration drops the metric-shifting padding; a btw fork send carries only the boundary instruction, never the promotion notice - sync: cascade revert/unrevert aborts busy descendants, busy state is read from every child store at the moment of use; rule 9 documents redo clearing all descendant revert markers - electron: renderer recovery keeps memory-eviction (a valid render-process-gone reason) and both windows share one attachRendererRecovery helper - vscode: process registry is a thin re-export of the web module (provider-env-aliases precedent) with ordered register/unregister writes and an awaited close - server/cli: managed-process registry takes injectable deps (fixes the unreaped-orphans ReferenceError), corrupt settings errors name the file, getWorktrees test restores console.warn - tests: module-mock harnesses removed (AgentsSidebar, SettingsView mobile focus — behaviors stay live but uncovered, accepted trade), QuestionMarkdown asserts rendered DOM - i18n: German gains the debug-panel request keys, Japanese/German drop removed worktree keys, Ukrainian unit spacing fixed - changelog: Copilot AI Credits entries (main + VS Code)

- Agent Manager — run the same prompt across multiple models in parallel, compare results side by side
- Right-click actions — add context, explain selections, and improve code in-place
- Click-to-open — file paths in tool output open directly in your editor; edit-style results land in a focused diff view
- Session editor panel — keep chat sessions open alongside files
- Theme-aware — adapts to your VS Code light, dark, and high-contrast themes
Plus everything from the shared OpenChamber UI: branchable timeline, smart tool UIs, voice mode, Git workflows, and more.
