Complete the Electron replacement boundary before merging by removing the renderer-side Tauri host fallback, tightening H5/browser access so only desktop navigation is tokenless, and moving desktop release publication to a tag-driven GitHub Actions matrix with a single final publish job.
Constraint: H5/browser capability access must not gain tokenless access through localhost or retired Tauri origins
Constraint: Desktop release artifacts must be built by GitHub Actions from version tags, not treated as local build outputs
Rejected: Keep localhost browser origins trusted for convenience | local browser contexts can access loopback services and must use the H5 token path
Rejected: Publish from each matrix job | partial releases can be created before all platforms finish
Confidence: high
Scope-risk: broad
Directive: Do not reintroduce Tauri origins or localhost browser origins into the trusted desktop origin set without a reviewed security design

Introduce the Electron desktop shell alongside the existing React renderer and local Bun server boundary. The migration keeps the DesktopHost contract explicit across Tauri, Electron, and browser runtimes while adding Electron main/preload services for dialogs, shell, notifications, updates, tray/window lifecycle, terminal, preview WebContentsView, app mode, and release/package validation.
The commit also carries the latest local main desktop command updates, including agent slash entries and hidden-by-default markdown thinking details, so the packaged Electron build matches the current main UX surface.
Constraint: React renderer, local Bun server, REST/WebSocket, and sidecar boundaries must remain reusable during the migration
Constraint: macOS dev packages are ad-hoc signed and cannot prove Developer ID notarization or Gatekeeper release launch
Rejected: Browser-only smoke validation | it cannot exercise native dialogs, keychain prompts, notification behavior, or packaged app startup

The desktop sidecar can bind on LAN addresses for phone access, so the H5 settings switch must be an authorization boundary for remote capability routes, not only a token-mode toggle. Remote browser API, proxy, websocket, and SDK routes now fail closed while H5 is disabled; local desktop, Tauri, WebUI, adapter, and internal SDK paths remain tokenless. When H5 is enabled, remote API, proxy, and websocket requests must use the H5 token carried by the QR link, and the server API key cannot substitute for that H5 token.
Constraint: Desktop sidecar binds 0.0.0.0 while reporting loopback to local UI.
Constraint: Client-controlled Host and Origin headers cannot prove a local request; the boundary uses Bun requestIP instead.
Constraint: Static H5 shell and /health must still load so browser bootstrap can show a recovery flow.
Rejected: Trust loopback Host headers | LAN clients can spoof Host and Origin.
Rejected: Use ANTHROPIC_API_KEY as a remote H5 credential | it is not the phone pairing token and would weaken the QR-token boundary.
Confidence: high
Scope-risk: moderate
Directive: Do not make h5Enabled=false an open remote state for /api, /proxy, /ws, or /sdk routes.
Tested: bun test src/server/__tests__/h5-access-policy.test.ts src/server/__tests__/h5-access-auth.test.ts src/server/middleware/cors.test.ts
Tested: bun run check:server
Remote browser access now needs the H5 token once LAN mode is enabled, but changing that mode remains a local desktop control-plane operation even when deployment auth is explicitly enabled. CORS also no longer treats a non-local same-origin alias as trusted unless it is the configured H5 public origin or allowlisted origin.
Constraint: H5 exposes desktop control surfaces on the LAN and must not let remote browsers enable their own access.
Constraint: Desktop WebView, localhost WebUI, SDK websocket, and IM adapter loopback calls must remain tokenless.
Rejected: Allow authenticated remote control-plane writes under SERVER_AUTH_REQUIRED | violates the local opt-in boundary for H5 exposure.
Confidence: high
Scope-risk: moderate
Directive: Do not relax /api/h5-access mutating endpoints for browser origins without adding a reviewed desktop-only trust signal.

Wire request-scoped H5 auth and CORS decisions through the server so LAN browser API, proxy, and websocket access require the H5 token while loopback desktop, Tauri WebView, local adapter, SDK, and static shell paths keep their existing bootstrap behavior.
Constraint: Task 2 scope is limited to server auth/CORS wiring and the four requested files
Rejected: Global auth toggle for all requests | would incorrectly block loopback desktop and bootstrap asset flows
Directive: Keep static H5 shell and assets tokenless unless the browser-side bootstrap model changes
Confidence: high

Not-tested: h5-access-auth runtime assertions because this checkout is missing zod for haha-oauth imports
The H5 token gate still caused chat startup and runtime failures after the desktop startup hotfix, so the default server path now stays open for browser and LAN access. Explicit auth remains available through SERVER_AUTH_REQUIRED=1 or --auth-required for deployments that intentionally need it.
Constraint: Current H5 token state is blocking active users from normal chat usage
Rejected: Keep automatic remote-host auth with broader client-side token handling | still leaves existing upgraded clients vulnerable to stale or missing token state
Confidence: high
Scope-risk: moderate
Directive: Do not re-enable default H5 token auth without a migration and end-to-end browser chat verification

Packaged desktop builds started the sidecar on loopback only, so phones on the same WiFi could not connect to the H5 URL. The server now binds to LAN interfaces while keeping the desktop control URL on loopback, serves the bundled H5 frontend, and reports a LAN public URL when H5 access is enabled.
Constraint: Packaged Tauri resources place ../dist under Contents/Resources/_up_/dist.
Rejected: Bind the desktop control URL to 0.0.0.0 | desktop clients should keep using loopback for local control.
Confidence: high
Scope-risk: moderate
Directive: Keep packaged H5 resource lookup aligned with Tauri resource mapping when changing bundle resources.

Remote browser access needs an explicit path that preserves localhost desktop behavior while allowing H5 tokens for REST and client websocket upgrades. This keeps the existing synchronous Anthropic auth helper intact, adds async request validation for H5 tokens, and centralizes origin handling so preflight, API, proxy, websocket, and health responses behave consistently.
Constraint: Existing validateAuth(req) must stay synchronous for current tests and callers
Constraint: Default localhost and Tauri desktop behavior must remain unchanged
Rejected: Replacing validateAuth with an async-only API | would break existing sync tests and call sites
Rejected: Allowing wildcard or fallback remote origins | violates the H5 explicit-origin security model
Directive: Restore ProviderService serverPort in server integration tests that call startServer with custom ports to avoid leaking global proxy runtime state

Not-tested: Full non-live server gate end-to-end; an attempted broader run was interrupted after uncovering and then fixing a test-side ProviderService port leak
Desktop failures were previously hard to debug from issue reports because server-side and CLI startup details were only partially visible in the UI. This adds a dedicated cc-haha diagnostics store with sanitized structured events, runtime error summaries, a Settings diagnostics view, and an exportable bundle that users can attach to reports.
Constraint: Diagnostic exports must not include chat content, file contents, full environment variables, API keys, bearer tokens, cookies, or OAuth tokens.
Rejected: Export raw server logs | easier to debug but too likely to leak secrets and private workspace data.
Rejected: Keep diagnostics only in transient UI errors | still leaves maintainers unable to diagnose later GitHub issues.
Confidence: high

Directive: Do not add raw transcript, prompt, attachment, or environment dumps to diagnostics without a separate privacy review.

origins from Tauri WebView, and add CORS headers to /health endpoint
- Enable native macOS window decorations (traffic lights) with Overlay title bar,
add data-tauri-drag-region on sidebar for window dragging
- Conditionally apply desktop-only padding (44px for traffic lights) vs web (12px)
- Generate brand identity: light-background app icon, horizontal logo, full icon
set (icns/ico/png) for Tauri bundle
- Add brand mark + GitHub link in sidebar, replace mascot SVG with app icon
in EmptySession page
- Update README (zh/en) and docs hero image with new branding
- Add sidecar build scripts and launcher entry points
- Gitignore Rust target/, Tauri gen/, and brand-assets candidates

Add complete server-side implementation for the Claude Code Desktop App UI:
- REST API: sessions, conversations, settings, models, scheduled tasks,
search, agents, and status endpoints (9 modules, 30+ endpoints)
- WebSocket: real-time chat streaming with state transitions, ping/pong,
permission request forwarding, and stop generation support
- Services: sessionService (JSONL read/write, CLI-compatible),
settingsService (atomic writes), cronService, searchService (ripgrep),
agentService (YAML management)
- Middleware: CORS (localhost-only), auth, unified error handling
- Tests: 180 tests (unit + E2E + business flow), all passing
- Docs: PRD, UI design spec, server architecture design
Non-invasive: all new code under src/server/, no changes to existing CLI code.
CLI/UI data interop: reads/writes the same JSONL/JSON files as the CLI.
