The first project opener UI used generic code glyphs for every IDE, which made the menu visually noisy and did not match the native desktop expectation. This changes the macOS path to expose transparent PNG icons generated from each detected local .app bundle and renders them directly in the toolbar/menu, falling back to the existing glyph only when an icon cannot be loaded.
Constraint: Do not redistribute third-party IDE trademark assets in the app bundle.
Constraint: Keep icon detection local to already detected open targets and cache only runtime PNG results.
Rejected: Bundling downloaded IDE logos | creates asset maintenance and trademark redistribution risk.
Rejected: Adding simple-icons as a dependency | it is not a faithful desktop app icon source and still requires brand permission checks.
Confidence: high
Scope-risk: narrow
Directive: Prefer local bundle icons on macOS; add curated official assets only as a cross-platform fallback layer.
Tested: bun test src/server/__tests__/open-target-service.test.ts src/server/__tests__/open-target-api.test.ts
Tested: cd desktop && bun run test -- src/stores/openTargetStore.test.ts src/components/layout/OpenProjectMenu.test.tsx src/components/layout/TabBar.test.tsx
Tested: cd desktop && bun run lint
Tested: bun -e openTargetService.getTargetIcon for vscode and finder returned PNG data
Tested: cd desktop && bun run build
Desktop sessions need a fast local escape hatch that opens the same materialized cwd the agent is editing, without showing unavailable IDE choices or persisting detection state. This adds a local open-targets API with silent in-memory detection for common IDEs and platform file managers, then wires a compact Codex-style toolbar menu into the desktop TabBar for active session workdirs.
Constraint: The first version is local IDE/editor and Finder/Explorer/file-manager only, no terminal targets or IDE plugin integration.
Constraint: The opened path must come from the active session workDir so isolated worktrees open the actual agent editing surface.
Rejected: Persisting detected applications | detection is cheap and temporary state avoids stale app inventory.
Rejected: Rendering unavailable IDEs as disabled menu rows | the user asked to show only detected targets and fall back to Finder/Explorer when no IDE is available.
Confidence: high
Scope-risk: moderate
Directive: Keep this path session-workdir based; do not switch it to repository root without proving isolated worktree behavior.
Tested: bun test src/server/__tests__/open-target-service.test.ts src/server/__tests__/open-target-api.test.ts
Tested: cd desktop && bun run test -- src/stores/openTargetStore.test.ts src/components/layout/OpenProjectMenu.test.tsx src/components/layout/TabBar.test.tsx
Tested: cd desktop && bun run lint
Tested: bun run check:desktop
Tested: bun test src/server/__tests__/h5-access-auth.test.ts -t 'allows local desktop H5 access settings under explicit server auth with a valid bearer'
Not-tested: bun run check:server full suite had one unrelated H5 auth integration timeout in the full concurrent run; the timed-out test passed when rerun alone.
