* Upgrade to Expo 57 and unify Explorer across layouts
* feat(app): retain Explorer across layout and appearance changes
Keep one workspace Explorer host and destination-aware navigation so folding, theme updates and compact sheets preserve the current panel. Scope pull request discovery and timeline demand to active surfaces.
* fix(app): keep Explorer resize handles stretched through the dock
The shared frame moved the divider into an absolute column, leaving its horizontal handle without height. Restore the row so pointer drags reach it, preserving the existing resize and performance contract.
* fix(app): keep Explorer drag widths out of the shared stylesheet
Carry the existing inline sizing policy into the shared frame so pointer previews do not accumulate CSS rules.
* fix(test): align isolated test runtimes with Expo 57
Hoisted React consumers need the matching DOM renderer at the repository root. Automated Metro processes must not install native DevTools into disposable homes, and development toast overlays must not cover compact actions.
Keep Explorer journeys on the shared host and synchronize setup fixtures on daemon output rather than a one-second file-marker window. A delayed real child start reproduces the readiness failure on every platform.
* fix(test): await retained shell layout after composer resize
The gesture host now stays mounted across breakpoints, so its presence no longer identifies compact layout. Report the current layout on the retained host and synchronize composer journeys with that state.
* fix(app): preserve browser interactions in retained workspace hosts
Initially disabled gesture hosts still registered pointer and wheel listeners, while hover cards used window positions inside a workspace-local sheet portal. Respect initial gesture enablement and position cards relative to their measured floating host.
Keep developer-toast dismissal independent of pointer input and replacement toast visibility so modal, hover, and focus checks retain their input state.
* fix(test): share developer toast handling with Electron browser runs
The standalone Electron browser runner bypassed the browser fixture, allowing developer errors to cover Settings. Use the same non-pointer dismissal in both runners while retaining their console logs.
* feat(app): modernize compact headers and sidebar affordances
Use a shared island header with quick tab creation and keep sheet footers inside their visible layout. Opt sidebar rows into touch sizing without changing global appearance settings.
* test(app): match darker light-theme workspace selection
* test(app): align plugin journeys with compact header
* feat(app): let users set the chat and Markdown content width
Wide and ultrawide screens were stuck with an 820px reading column. The
width is now an Appearance setting that flows through the Unistyles theme,
like the font sizes, so every content surface picks it up.
The stored value stays null until the user picks a width, so a future
change to the default reaches everyone who never customized it. Reset
writes null back.
The native composer dock keeps plain React Native styles and takes the width
inline because those styles land on Reanimated views, where theme-driven
Unistyles crash on theme changes.
* fix(app): pass the content width into the web stream viewport
The viewport read app settings itself, which required a QueryClient in every
render of the stream strategy. The agent stream view already reads settings,
so it hands the width over with the rest of the render input.
* fix(app): preserve desktop layout in half-screen windows
Treat native window controls as physical corner obstructions instead of deriving clearance from compact layout state. Keep 751px windows in desktop mode while preserving usable content when persisted sidebars are wide.
* fix(app): retain sidebar width across window resizes
* fix(app): yield app sidebar to narrow settings
* test(app): wait for mobile sidebar motion to settle
* fix(app): yield navigation to narrow workspace explorer
* fix(app): mark sidebar sizing helpers as worklets
* fix(app): hide app navigation when space is constrained
Add `packages/app/src/constants/platform.ts` with canonical gates
(isWeb, isNative, getIsElectron) and refactor all ~100 ad-hoc
Platform.OS checks across 69 files to use shared imports.
Fix sidebar hover crash on native (onPointerEnter → onHoverIn),
fix tooltip to use breakpoint instead of platform detection, make
sidebar action buttons always visible on native where hover doesn't
work, and document the platform gating decision matrix in CLAUDE.md.
Replaces useTrafficLightPadding with a role-based useWindowControlsPadding
hook that absorbs all layout-conditional logic (sidebar state, focus mode,
explorer state). Consumers no longer make platform or layout decisions —
they just apply the resolved padding values.
Fixes Windows title bar overlay buttons overlapping source control icons
when the left sidebar is open, and right padding not shifting to the
explorer sidebar header when it's open.
Also fixes borderless header using borderBottomWidth:0 (layout shift)
instead of transparent, and double-click-to-maximize bounce on the
open project screen caused by nested drag handlers.
Use titleBarStyle: 'hidden' on all platforms. On Windows/Linux, enable
titleBarOverlay with dark theme colors for native min/max/close buttons.
Extend useTrafficLightPadding to return side ('left'|'right'|null) so
consumers apply padding on the correct side per platform.
- Add MAX_CONTENT_WIDTH (820px) constant for consistent chat/form widths

- Remove working directory helper text
- Add cmd+b sidebar toggle when textarea is focused
- Add debug logging for tool call payloads in agent-stream-view
- Add e2e tests to verify tool call structure for Claude and Codex agents
- Include sidebar toggle and horizontal scroll improvements from previous work

Replace portal/registry pattern with direct rendering where each screen
owns its footer. This eliminates FooterControlsContext indirection and
makes the code follow standard React composition patterns.
- Remove GlobalFooter and FooterControlsProvider from _layout.tsx
- Add HomeFooter component rendered directly in home screen
- Render AgentInputArea directly in agent screen (not via registration)
- Add keyboard animation and safe area handling to AgentInputArea
- Move FOOTER_HEIGHT constant to shared constants/layout.ts
- Delete footer-controls-context.tsx and global-footer.tsx
