The desktop shell now owns sidebar collapse state, the collapsed rail keeps a
visible recovery affordance, and keyboard search expands the sidebar before
focusing. The UI work also smooths the width transition so the main chat area
can take over without the previous abrupt cutover.
Constraint: The desktop app must keep a recovery path visible in narrow layouts on macOS and Windows
Constraint: Existing sidebar behavior needed regression coverage before further UI work
Rejected: Fully hide the sidebar at 0 width | recovery affordance became too fragile for this iteration
Rejected: Keep boxed restore controls in the collapsed rail | visually heavy and easy to misplace
Confidence: medium
Scope-risk: moderate
Reversibility: clean
Directive: Keep the collapsed rail width and the inner sidebar panel width in sync or expand controls will be clipped again
Tested: cd desktop && bun run lint
Tested: cd desktop && bun run test Sidebar.test.tsx
Not-tested: Full desktop manual pass across every app screen after the final icon/layout tweaks
- security: XSS sanitization with DOMPurify in Markdown/Mermaid/PermissionDialog;
path whitelist in filesystem API; fake keys in test/config files
- perf: fine-grained Zustand selectors in Sidebar/StatusBar/ContentRouter;
50ms throttle on streaming deltas; React.memo + useMemo in MessageList;
useRef for frequent keyboard shortcut state; AbortController 30s timeout
- leaks: WS session TTL timers (5-min cleanup on close); batch splice for
sdkMessages/stderrLines; folderPath validation in cronScheduler
- quality: optimistic update rollback in settingsStore; error state in
providerStore/teamStore; i18n for all hardcoded English strings
- docs: desktop architecture and features docs updated; VitePress nav fixed

Update all components, hooks, and tests to use the new per-session
chatStore API where state is keyed by sessionId under `sessions` and
all action methods require sessionId as the first parameter.

The desktop app now keeps the composer stable while turns are active,
reduces low-signal tool noise in the transcript, restores project context
under the composer after session creation, and relies on the CLI's own
permission requests instead of injecting broader desktop-side Bash asks.
This also brings in the supporting desktop app source tree and the server
routes/session metadata needed for git info, filesystem browsing, session
resume, slash commands, and SDK-backed permission bridging so the UI can
operate as a coherent feature instead of a partial patch.
Constraint: Desktop transcript needs to stay usable during long multi-tool sessions without hiding file-change diffs
Constraint: Permission prompts must mirror CLI behavior closely enough that read-only commands do not get desktop-only prompts
Rejected: Keep rendering Read/Bash bodies inline | too noisy and unlike the intended transcript model
Rejected: Commit only the touched desktop files | would leave the newly introduced desktop app incomplete in git history
Confidence: medium
Scope-risk: broad
Reversibility: messy
Directive: Treat non-writing tools as summary-first transcript events; do not re-expand them by default without validating the UX against long sessions
Tested: cd desktop && bun run lint
Tested: cd desktop && bun run test -- --run
Tested: bun test src/server/__tests__/conversations.test.ts
Not-tested: Manual visual regression against the exact screenshots in a live desktop session
Not-tested: Full root TypeScript check (repository still has unrelated extracted-native parse failures)
