feat(cli): add --project and --global flags to /model for per-project model persistence (#6060)
* feat(cli): add --project and --global flags to /model for per-project model persistence

Add scope control to the /model command so users can persist model
selections to either project-level or user-level settings independently.

- /model --project: persist to workspace .qwen/settings.json
- /model --global: persist to user ~/.qwen/settings.json
- /model (no flag): unchanged behavior (backward compatible)
- Model dialog title shows scope: 'Select Model (this project)' / 'Select Model (global)'
- Completion and argumentHint updated with new flags
- Full i18n support for zh/en

Closes #6052

* fix(cli): add missing zh-TW translations for /model scope flags

Signed-off-by: Alex <alex.tech.lab@outlook.com>

* fix(cli): address PR review — scope flags, subcommand persistScope, titles, tests

- parseScopeFlags: use (?:^|\s) instead of \b for --flag matching
  (\b fails because - is not a word character)
- Completion: strip all flags to isolate model prefix, supports any order
- Subcommand dialogs (fast/voice/vision) now propagate persistScope
- slashCommandProcessor forwards persistScope for all subcommand cases
- ModelDialog title combines subcommand mode + scope label
  e.g. 'Select Fast Model (this project)'
- Subcommand confirmations show scope suffix (project/global)
- Extract persistScopeSpread() helper to reduce duplication
- Add 9 tests covering scope flags, dialog returns, confirmations
- Add i18n keys for scope suffix labels in zh/en/zh-TW

* fix(cli): use Partial<Config> & {[key:string]:unknown} to fix index signature TS error

Replace Record<string,unknown> with Partial<Config> & {[key:string]:unknown}
to satisfy TS4111 index signature access rule in the CI build.

* fix(cli): add scope suffix to ModelDialog history items

Address review comment: historyManager.addItem for voice/fast/vision/main
model selections now shows scope indicator like ' (this project)' or
' (global)', consistent with CLI direct-set confirmations.

Affected: handleModelSwitchSuccess (main), handleSelect (voice/fast/vision)

* fix(cli): wrap scopeSuffix in t() and unify wording with ModelDialog

- scopeSuffix in modelCommand.ts now uses t(' (this project)') / t(' (global)')
  instead of hardcoded English strings, matching ModelDialog.tsx wording
- Main model confirmation uses shared scopeSuffix instead of separate
  i18n keys, eliminating 'Model: {{model}} (project)' duplication
- Remove unused i18n keys from en/zh/zh-TW locales
- Update tests to expect '(this project)' wording

* fix(cli): reject --project when workspace is untrusted

Reject --project scope flag before direct persistence or opening ModelDialog
when settings.isTrusted is false. Workspace settings are ignored on merge in
that state, so the save would silently not take effect.

Also mirrors the guard in ModelDialog.tsx resolvePersistScope() to fall back
to user scope when the dialog is opened with --project on an untrusted folder.

Default mock settings now includes isTrusted: true.

* refactor(chrome-extension): rename chrome-qwen-bridge package to chrome-extension

* feat(chrome-extension): enhance network monitoring with webRequest API

Replace the existing network monitoring implementation with a more comprehensive solution that combines both webRequest and debugger APIs for broader coverage. The new implementation:

- Uses chrome.webRequest.onBeforeRequest to capture all outgoing requests
- Uses chrome.webRequest.onCompleted to capture completed responses
- Uses chrome.webRequest.onErrorOccurred to capture failed requests
- Retains debugger API integration for detailed network information
- Implements memory management with maximum 1000 logs per tab
- Adds proper initialization and cleanup for each tab
- Ensures graceful handling of debugger attachment failures
- Provides more reliable network activity capture across all tabs

This enhancement significantly improves the reliability and coverage of network monitoring functionality in the Chrome extension.

* refactor(chrome-extension): reorganize directory structure for better maintainability

This commit reorganizes the entire Chrome extension package structure for improved maintainability and clarity:

- Move all source files to `src/` directory (background, content, sidepanel)
- Move build configurations to `config/` directory
- Move documentation to `docs/` directory with proper categorization
- Move all script files to `scripts/` directory
- Move native-host specific files to appropriate subdirectories (`src`, `scripts`, `config`)
- Update package.json scripts to reflect new file locations
- Add comprehensive documentation files (debugging, development, architecture, API reference)
- Maintain all functionality while improving project organization

The reorganization separates source code from build output, centralizes documentation, and creates a clear separation of concerns making the project more maintainable and easier for developers to navigate.

* feat(chrome-extension): enhance native host communication and network logging

- Add troubleshooting documentation for native host setup issues
- Improve native host logging to home directory with fallback to tmp
- Enhance network logging in service worker with response body capture
- Update scripts to properly reference host.js from correct path
- Increase timeout for MCP session creation and long prompts from 3 to 5 minutes
- Add getConsoleLogs functionality to sidepanel for content script capture
- Improve browser-mcp-server network logs aggregation by request ID
- Update icon assets and improve manifest configuration

refactor(chrome-extension): consolidate host.js entry point and improve path resolution

- Create unified host.js entry point that delegates to src/host.js
- Improve path resolution for host scripts in installer and runner scripts
- Add proper path existence checks for browser-mcp-server.js
- Support running from different directory structures

style(chrome-extension): improve TypeScript type safety and error handling

- Add proper type definitions for message handling in side panel
- Add null checks and error handling for message parsing
- Improve React component callback implementations

* refactor(chrome-extension): redesign build workflow

* fix(chrome-extension): resolve ESLint errors in native host, service worker, and content script

- Fix 'Unexpected lexical declaration in case block' by wrapping switch cases in blocks
- Fix 'Unexpected constant truthiness on the left-hand side of a || expression' by using conditional patterns
- Fix unused variable errors by properly using catch error parameters or adding logging
- Fix 'document' and 'window' not defined errors in service worker with proper global declarations
- Add eslint-disable comments where appropriate for globals used in specific contexts

* feat(chrome-extension): enhance native host with browser MCP tools and event streaming

- Add new browser MCP tools: browser_click, browser_click_text, browser_run_js, browser_fill_form_auto
- Implement SSE (Server-Sent Events) for improved event streaming instead of long-polling
- Add daemon script for running the bridge host in background
- Enhance documentation with MCP notes and updated README
- Add multiple executable binaries to package.json: chrome-browser-mcp, qwen-bridge-host
- Improve error handling and event processing in the native host
- Add debouncing mechanism for stream end events in service worker
- Update timeout for MCP discovery to accommodate slower startup

* fix(chrome-extension): use trusted cwd for MCP tool discovery

The root cause of MCP tools not being recognized by Qwen CLI was that
the cwd (current working directory) was defaulting to '/' (root directory).

In Qwen CLI's MCP discovery logic, there's a security check:
  if (!cliConfig.isTrustedFolder()) {
    return;  // Skip MCP tool discovery
  }

The root directory '/' is not a trusted folder, so MCP tools were
silently not being discovered at all.

Changes:
- host.js: Default to $HOME instead of process.cwd() for start_qwen
- service-worker.js: Remove '/' fallback, let host.js handle default

This ensures browser MCP tools (browser_read_page, browser_click, etc.)
are properly discovered and available to the model.

* fix(core): validate MCP entry script existence before connection

Add pre-flight check to verify that stdio-based MCP server entry scripts
exist on disk before attempting connection. This prevents silent failures
and provides clear error messages for misconfigured MCP servers.

* fix(chrome-extension): enhance native host path resolution and port config

- Add QWEN_BROWSER_MCP_SERVER_PATH env override for custom installations
- Expand candidate search paths for browser-mcp-server.js discovery
- Add detailed logging when MCP server script is not found
- Support BRIDGE_PORT env variable for HTTP API server configuration

* fix(chrome-extension): improve browser MCP server reliability and debugging

- Add comprehensive debug logging for bridge health checks and host spawn
- Support BROWSER_MCP_NO_SPAWN env to disable automatic host.js spawning
- Handle bridge unavailability gracefully with clear error messages
- Add raw JSON mode fallback for clients without Content-Length framing
- Capture and log host.js stdout/stderr instead of inheriting stdio
- Add pre-flight bridge check at startup for better diagnostics
- Handle each bridge call failure with proper error responses

* chore(chrome-extension): add debug wrapper script for MCP server

Add cbmcp-wrapper.sh to help diagnose MCP server invocation issues.
The wrapper logs invocation details and stderr to /tmp/cbmcp.log,
making it easier to debug when Qwen CLI spawns the MCP server.

* docs(chrome-extension): add MCP/Bridge troubleshooting guide

Document common failure scenarios when MCP bridge shows as Disconnected:
- EPERM errors when spawning host.js cannot bind to port
- Content-Length framing issues during MCP handshake
- Step-by-step troubleshooting with flow diagrams
- Manual bridge setup with BROWSER_MCP_NO_SPAWN workaround

* build(chrome-extension): 浏览器插件 mcp 构建优化

* docs(chrome-extension): update docs

* fix(chrome-extension): 解决CDP响应体获取和权限请求处理问题

* feat(mcp-chrome-integration): add MCP Chrome browser extension integration

Add complete Chrome extension with native messaging host for MCP integration:
- Chrome extension with sidepanel UI, service worker, and content script
- Native server with agent engines (Claude/Codex), session management, and tool bridge
- Shared packages for types, tools, and node specifications
- Documentation and build scripts

* chore: regenerate lockfile for mcp-chrome-integration workspace

npm install reconciles the lock with the merged package.json: adds the
new packages/mcp-chrome-integration/app/* workspace subtree (371 deps).
No existing main dependencies were removed.

* chore(chrome-integration): drop dead logger + unused pino deps

native-server/src/util/logger.ts was 100% commented-out dead code (even
a hardcoded /Users/hang/... path) with zero importers; pino/pino-pretty
were declared but never imported (logging is console.error to stderr,
correct for a native-messaging host). Remove the file and both deps.

* feat(chrome-integration): WIP serve-backed agent client (Phase 1 backbone)

Replace the hand-rolled ACP client by driving `qwen serve` (main's
maintained HTTP daemon) through the SDK's DaemonClient. New
serve-agent/client.ts spawns `qwen serve --no-web` where the host used to
spawn `qwen --acp`, then uses DaemonClient (REST + SSE) for session
create / prompt / cancel / permission / streaming. Same public surface as
AcpClient so the native host can swap in place.

Compiles + typechecks against the real SDK API. NOT yet wired into
native-messaging-host.ts — wiring is gated on two items that need runtime
validation in a real Chrome + qwen env:
  - OAuth: host's onAuthenticateUpdate (in-extension authUri) maps to
    serve's server-side device-flow events — needs design.
  - permission requestId becomes string (was number) — host's
    permissionRequests map + handler need to follow.

acp/ kept in place until the serve path is validated. Packaging follow-up:
@qwen-code/sdk (→ core) as a dep of the standalone host is fine in the
monorepo but needs a publish-time story (bundle or resolve from the
co-installed qwen).

* feat(browser-ext): daemon-direct connection foundation (Phase 1, #5626)

First brick of the daemon-direct architecture from #5626: the extension
talks straight to a local `qwen serve` HTTP daemon instead of a native
messaging host.

- daemon/config.ts: resolve { baseUrl, token } — default loopback
  http://127.0.0.1:4170 (auth-free), overridable via chrome.storage.local.
- daemon/discovery.ts: GET /health probe so the side panel can show a
  "start qwen serve" hint instead of a broken chat when no daemon is up.

Both typecheck clean. (Pre-existing tsc errors live only in the orphaned
legacy sidepanel hooks — useWebViewMessages/useToolCalls etc. — which the
DaemonSessionProvider migration removes next.)

* docs(browser-ext): daemon-direct architecture spec (Phase 1+2, #5626)

Concrete implementation spec: Phase 1 (side panel as daemon client, no
daemon changes) and Phase 2 (browser tools as a client-hosted MCP server
over the daemon WS). Phase 2 reuses the existing SdkControlClientTransport /
SdkControlServerTransport pattern but moves the wire from the SDK subprocess
control plane onto qwen serve's WebSocket — a new public daemon-contract
surface, gated behind a capability flag (the open question in #5626).
Includes the daemon-lifecycle options for #5626 Q3.

* feat(browser-ext): Phase 1 — side panel as a daemon-direct client (#5626)

Side panel chat now talks straight to a local `qwen serve` HTTP daemon via
@qwen-code/webui's DaemonSessionProvider, replacing the native-messaging
relay (background/ + content/ untouched; nativeMessaging perm kept for now).

- SidePanelRoot.tsx: health gate — checkDaemonHealth(getDaemonConfig());
  shows a "run qwen serve" hint + Retry when unreachable, else mounts
  DaemonSessionProvider around App.
- App.tsx: rewritten daemon-driven — transcript/streaming/permissions/
  lifecycle from the webui daemon hooks (useTranscriptBlocks, useStreamingState,
  usePromptStatus, usePendingPermissions, useConnection, useActions); reuses
  the existing webui presentational components + ChromePlatformProvider.
- sidepanel/daemon/{transcriptItems,permission}.ts: adapters from daemon
  transcript/permission shapes to the existing UI components.
- Deleted the dead legacy native-messaging chat hooks/types.

Verified: sidepanel/daemon tsc clean; `npm run build` (esbuild) passes,
emits the side-panel bundle with the daemon wiring. (Pre-existing tsc errors
remain only in background/ + content/, out of scope until Phase 2.)

Daemon contract accepted live against the worktree `qwen serve`: /health,
/capabilities (advertises session_create/prompt/events/workspace_mcp),
POST /session runs end-to-end to the model-auth gate.

* feat(browser-ext): Phase 2 — browser tools over the daemon WS (#5626)

Reverse tool channel: a WS client (the extension) hosts an MCP server (its
browser tools) that the daemon's agent can call, carrying mcp_message
JSON-RPC frames over the daemon WS — reusing the SdkControlClientTransport /
SDK-MCP-server control-plane pattern. Gated behind capability flag
`client_mcp_over_ws` (opt-in; the public-contract piece flagged in #5626).

Daemon (core + cli/serve):
- core/tools/client-mcp-registrar.ts: ClientMcpRegistrar — id-correlation,
  pending/timeout, notifications fire-and-forget, exposes the
  sendSdkMcpMessage(server,msg) callback McpClientManager consumes.
- cli/serve/acp-http/client-mcp-ws.ts: ClientMcpWsConnection — handles
  mcp_register/mcp_message/mcp_unregister frames; pushes mcp_message down the
  WS; disposes on close. Hookup to the live agent McpClientManager is a
  ClientMcpServerProvider injection point (returns structured `not_wired`
  until the child↔parent reverse-IPC lands — see below).
- capability `client_mcp_over_ws` threaded through serve options/capabilities.

Extension (chrome-extension/background):
- browser-tools-server.ts: minimal hand-rolled MCP JSON-RPC
  (initialize/tools/list/tools/call) reusing the existing tool-catalog +
  router + executors (MVP 6 read-first tools); WS client to the daemon /acp
  with mcp_register + reconnect. Wired into the service worker behind a
  health probe; native messaging left intact.

Self-accepted (no LLM needed): 10/10 tests pass — a headless ws client
registers + answers the MCP handshake over mcp_message and the daemon
lists+CALLS the client-hosted chrome_read_page tool end-to-end over a real
socket. Builds: core + cli + extension esbuild all green; tsc clean.

NOT yet wired (out of scope here; needs acp-bridge + acpAgent reverse IPC):
the parent-process WS ↔ ACP-child McpClientManager hookup — the daemon's WS
lives in the parent serve process but sendSdkMcpMessage binds in the ACP
child. Single injection at the mountAcpHttp call site once that IPC exists.

* feat(serve): wire client-MCP-over-WS to the ACP child agent (#5626)

Closes the Phase 2 gap: a client-hosted (extension) MCP server's tool calls
now reach the agent's McpClientManager in the ACP CHILD, routed back to the
parent's ClientMcpRegistrar and out over the daemon WS. Opt-in via
QWEN_SERVE_CLIENT_MCP_OVER_WS=1 (the contract is still settling — dormant by
default; this is the public-daemon-contract piece flagged in #5626).

Contract additions:
- ACP ext-method `qwen/control/client_mcp/message` (child→parent, called UP):
  {server,payload} → {payload}; notifications resolve with a synthetic ack.
- runtime-MCP config flag `__clientMcpOverWs`: parent stamps it on the SDK-type
  add config; child KEEPS type:'sdk' (instead of stripping) so it binds an
  SdkControlClientTransport instead of the SDK subprocess control plane.
- BridgeOptions.clientMcpSender seam + ServeAppDeps.clientMcpSenderRegistry.

Round-trip: mcp_register(WS) → serve registers the connection's
ClientMcpRegistrar.sendSdkMcpMessage in a process ClientMcpSenderRegistry +
bridge.addRuntimeMcpServer(type:'sdk',__clientMcpOverWs) → child adds the
SDK server + runs initialize/tools/list, each frame child→parent via
client_mcp/message → BridgeClient looks up the sender → registrar pushes
mcp_message down the WS → extension answers → child discovers the tools.

Self-accepted LIVE (no LLM): integration-tests/cli/qwen-serve-client-mcp.test.ts
spawns a REAL qwen serve + REAL qwen --acp child under a mock OpenAI server,
a headless ws client registers + answers the MCP handshake, and the child
discovers the client-hosted chrome_read_page tool over the genuine
child→parent→WS channel (GET /workspace/mcp/chrome-tools/tools lists it).
Verified passing locally (24.6s). +5 bridge round-trip tests; 324 acp-bridge,
the 10 prior Phase-2, acpAgent 133, server+acp-http 675 all pass; builds clean.

Not exercised here: a real LLM turn driving tools/call (needs creds), and a
real Chrome extension as the WS client (headless ws stands in).

* fix(serve): session-scope runtime MCP servers so client tool calls resolve (#5626)

The reverse tool channel registered the client-hosted MCP server only on the
bootstrap/workspace Config, so discovery worked but a prompt — which runs
against an independent per-session Config from newSessionConfig→loadCliConfig
— couldn't resolve the tool ("not found in registry"), and the reverse WS
channel was never reached. Spec (docs/05) intends per-session scope.

Fix (minimal, additive, guarded; normal settings-based MCP servers unaffected):
- core/config.ts: add Config.getRuntimeMcpServers() (shallow copy of the
  private runtimeMcpServers map).
- acpAgent.ts newSessionConfig: copy the bootstrap Config's runtime MCP
  servers into a newly-created session Config before initialize() so its
  discovery binds that session's sendSdkMcpMessage (register-before-session).
- acpAgent.ts workspaceMcpRuntimeAdd/Remove: fan the add/remove out to every
  active session's McpClientManager (register-after-session), best-effort.

Test: the fake model now emits the fully-qualified registered name
mcp__chrome-tools__chrome_read_page (what a real model is handed); the
reverse channel still forwards the bare tool name to the client server.

Verified LIVE (no LLM, no creds): integration test now drives the FULL loop —
model→agent→session-registry resolution→reverse client_mcp/message over the
daemon WS→headless ws client returns CallToolResult→agent consumes it (tool
completed)→turn_complete. 2/2 integration tests pass (confirmed locally).
Regression: config 248, acpAgent 133, mcp-client-manager 101, client-mcp-ws 5
pass; builds clean. (server.test.ts has 2 pre-existing Web-Shell flakes,
identical on the unmodified baseline.)

Still needs a real Chrome extension (vs the headless ws stand-in) + a real
model turn for true browser behavior; the protocol round-trip is proven.

* chore(browser-ext): remove the dead Native Messaging stack (#5626)

Daemon-direct made Native Messaging obsolete — the extension talks to
`qwen serve` directly (chat over HTTP+SSE, browser tools over the daemon WS),
so the entire native-host stack is dead weight. Deletes ~15.5k lines:

- packages/mcp-chrome-integration/app/native-server/ — the whole native host
  (MCP servers, ACP client, Fastify server, doctor/register/report/postinstall,
  the superseded serve-agent backbone).
- extension background transport: native-messaging.ts, native-connection.ts,
  native-message-handler.ts, native-messaging-types.ts, ui-request-router.ts
  (+ its test). The still-used executor types (BrowserToolArgs / RawNetworkRequest
  / WebSocketSession / NetworkCaptureState) move to background/browser-tool-types.ts.
- service-worker rewired to daemon-direct only (drops the NativeMessaging
  init + the onMessage→routeUiRequest relay; keeps the browser-tools server start).
- esbuild.background.config.js drops the deleted native-messaging entry point.
- manifest.json drops the `nativeMessaging` permission.
- package.json scripts drop every native-server/native-host reference; dev-watch
  no longer spawns the native host.
- obsolete native-messaging docs (01-04) + scripts (diagnose/install/update) removed;
  README rewritten for daemon-direct.

Extension esbuild build green; tsc errors dropped (84 -> 69, all pre-existing
node:test/content typings). Daemon-side (cli/serve/core) untouched.

* chore(browser-ext): drop orphaned content-fetch-patch.ts (#5626)

* fix(serve): let browser extensions open the daemon WS reverse channel

The daemon-direct Chrome extension (#5626) connects to qwen serve's /acp
WebSocket to register its browser tools as a client-hosted MCP server.
Three gaps blocked the real-browser path. A node WS client in the
integration tests carries no browser Origin and completes the ACP
handshake, so none of these surfaced until a real Chrome connected:

- The WS CSRF check hard-coded loopback origins, so the extension's
  chrome-extension://<id> Origin was rejected with 403. Wire the
  existing --allow-origin allowlist into the WS upgrade check
  (acp-http/index.ts, server.ts) with the same match semantics as the
  REST allowOriginCors.
- parseAllowOriginPatterns rejected chrome-extension:// because its
  URL.origin is the opaque "null". Rebuild the canonical origin from
  scheme+host for opaque-origin schemes (auth.ts), with tests.
- The extension skipped the ACP initialize handshake and sent
  mcp_register directly, tripping the daemon's 30s initialize timeout.
  Send ACP initialize first and register only after the ack
  (browser-tools-server.ts).

Also allow console.* in the extension package (no stdio in the MV3
runtime) via the eslint no-console allowlist.

Verified end-to-end against a real Chrome: the daemon agent calls
mcp__chrome-tools__chrome_read_page and reads the live active tab.

* docs(browser-ext): Plan C (CDP tunnel) feasibility + implementation design

Assess routing chrome-devtools-mcp's ready-made DevTools toolset through the
extension's chrome.debugger to drive the user's real browser, instead of
re-implementing each tool in the extension (Plan A). Records, with source
verification against chrome-devtools-mcp@1.4.0 + puppeteer-core@25.2.0:

- the createCDPSession wall (why zero-change reuse fails — Target.attachToTarget
  is "Not allowed" for chrome.debugger; cdp-mcp throws in McpContext.from);
- the patch-package fork shape (pin 1.4.0 + a ~2-site patch, not vendor/submodule);
- the daemon /cdp browser-level CDP emulation + sessionId routing design;
- minimal browser-level command set, reusable prior art (playwright-mcp
  --extension), phased steps, risks, and the Plan A fallback.

Refs #5626.

* feat(serve): add CDP browser-level emulator for Plan C tunnel (#5626)

First component of the Plan C "CDP tunnel": a synthesis layer that fakes the
browser-level CDP topology so an external puppeteer client (chrome-devtools-mcp)
can connect over a future /cdp endpoint while page-domain commands are forwarded
to the one real tab via the extension's chrome.debugger.

Implements the exact contract a Phase 0 spike proved necessary: a tab->page
two-level target tree + recursive Target.setAutoAttach (browser attaches the tab
session; the tab session attaches the page session), with page-session commands
routed to forwardToTab and tab events re-tagged with the page session id. The
spike connected real puppeteer to a pure synthesis layer and ran
page.evaluate(() => 1 + 1) === 2. 7 unit tests cover the handshake + routing.

Refs #5626.

* feat(serve): add CDP tunnel reverse-link, /cdp glue, and bridge registry (#5626)

Plan C Phase 1 daemon core. The reverse-link forwards page-domain CDP
commands to the extension over cdp_command/cdp_result frames (id-correlated,
timeout) and re-tags cdp_event onto the page session; cdp-ws wires a per-
puppeteer-connection emulator to the reverse-link bound to the single active
extension bridge in a process-scoped registry. The emulator gains setTabInfo
so the synthetic targetInfo reflects the real tab after cdp_attach.

* feat(serve): wire /cdp upgrade branch and cdpTunnelOverWs flag (#5626)

Adds the /cdp WebSocket upgrade branch to acp-http (reusing the loopback /
host-allowlist / auth / CSRF checks) and routes inbound cdp_* frames on the
extension's /acp socket to the bound reverse-link. The extension connection
registers as the active CDP bridge eagerly at ACP initialize so a /cdp
puppeteer client can bind immediately (avoids the attach chicken-and-egg).
Feature flag cdpTunnelOverWs is wired exactly like clientMcpOverWs
(env QWEN_SERVE_CDP_TUNNEL_OVER_WS=1, capability cdp_tunnel_over_ws),
DEFAULT OFF — existing behaviour is unchanged when off.

* feat(browser-ext): add CDP bridge over the reverse /acp socket (#5626)

The extension answers cdp_attach by attaching chrome.debugger to the active
tab and cdp_command via chrome.debugger.sendCommand, replying cdp_result;
chrome.debugger.onEvent -> cdp_event, onDetach -> cdp_detach. Reuses the
existing browser-tools-server /acp socket (routes cdp_* frames; tears the
bridge down on socket close) and mutually excludes with the
chrome_network_debugger_* tools (one debugger per tab).

* build(deps): pin chrome-devtools-mcp 1.4.0 + puppeteer-core 25.2.0, patch McpContext (#5626)

Pins the two CDP-tunnel client deps (exact, to keep the version-specific
patch and puppeteer's hardcoded ExtensionTransport topology stable) and adds
patches/chrome-devtools-mcp+1.4.0.patch. The patch wraps McpContext.#init's
devtoolsUniverseManager.init / serviceWorkerConsoleCollector.init in try/catch
so the createCDPSession wall (Target.attachToTarget -> -32000 over
chrome.debugger) no longer crashes the server on startup; only performance_* /
service-worker console degrade. Applied via the existing postinstall
patch-package hook (same form as patches/ink+7.0.3.patch).

* test(serve): add Plan C /cdp end-to-end acceptance harness (#5626)

Node script that starts the real daemon with the flag on, connects a mock
extension over /acp (ACP initialize + mcp_register, answering cdp_command with
page-domain CDP), then puppeteer.connect to /cdp and asserts
page.evaluate(() => 1 + 1) === 2 through the real daemon + emulator +
reverse-link. Allowlists the harness dir in eslint's node-script globals.

* fix(serve): gate CDP page commands behind attach completion (#5626)

Real-Chrome testing surfaced an ordering race the mock acceptance missed: the
extension's chrome.debugger.attach is async (it pops the debugger banner), but
forwardToTab forwarded page-domain commands immediately, so a fast puppeteer
Network.enable reached the extension before attachedTabId was set and failed
"CDP tunnel not attached to a tab". The mock extension acked attach
synchronously, which hid the race.

Add an attach gate in CdpReverseLink: forwardToTab awaits the in-flight
cdp_attach to settle (success or failure) before forwarding. Verified
end-to-end against REAL Chrome — puppeteer read the live active tab (a GitHub
PR page) through the tunnel: pages=1, real url/title/body returned.

Refs #5626.

* refactor(chrome-extension): delete Plan A side panel, content scripts, and reverse tool channel

Tears out the superseded Plan A surface so the extension can become a pure
CDP-tunnel pipe (chat moves to the daemon web UI, browser tooling runs as
chrome-devtools-mcp over the /cdp tunnel):

- src/sidepanel/ (side-panel chat UI)
- src/content/ (content scripts; the CDP tunnel drives DOM/Input via
  chrome.debugger, no injection needed)
- background reverse tool channel: browser-tools-server, browser-network-tools,
  network-capture-utils, browser-tool-executors, tool-catalog, tool-router,
  mcp-tool-result, browser-tool-types, and their tests
- public/sidepanel/sidepanel.html static asset

Refs #5626

* refactor(chrome-extension): rewrite service worker as minimal daemon CDP client

The service worker is now the entire extension logic: probe the daemon /health,
open the /acp WebSocket, send the ACP initialize handshake (the daemon closes
the socket on a 30s init timeout otherwise and binds this connection as the CDP
bridge at that point), then route cdp_* frames into the CDP bridge with capped
backoff reconnect. No more reverse MCP tool server (chrome-tools is gone).

cdp-bridge: drop the browser-network-tools import and the network-capture
mutual-exclusion branch in handleAttach (the network tools are deleted, nothing
to exclude); remove the now-unused isCdpTunnelAttached export.

Refs #5626

* build(chrome-extension): trim manifest, build config, and deps to the CDP pipe

manifest: drop content_scripts, side_panel, and the sidePanel/webRequest/cookies/
scripting/webNavigation permissions; keep only debugger/tabs/activeTab/storage
plus background, key, host_permissions, icons, and action.

build: background esbuild now has a single service-worker entry point (content
script gone); delete the UI esbuild/postcss/tailwind configs and drop the UI
build step + build:ui scripts; sync-extension no longer special-cases the gone
sidepanel assets; dev-watch no longer spawns the UI watcher.

deps: remove the side-panel-only deps (@qwen-code/webui, react, react-dom,
markdown-it, and the @types + the postcss/tailwind/autoprefixer CSS toolchain).

* fix(extension): keep the CDP tunnel alive with chrome.alarms

MV3 service workers idle out after ~30s, so the tunnel silently dropped
whenever no puppeteer client was driving it and the user had to keep the
Service Worker DevTools open to hold the worker awake. Register a 30s
chrome.alarms keepalive: the recurring onAlarm dispatch holds the idle
timer off, and each wake of a terminated worker re-runs the top level to
reconnect.

* feat(serve): auto-register chrome-devtools-mcp over the CDP tunnel

Plan C (#5626) last mile: when `qwen serve` runs with the CDP-tunnel flag,
the agent should be able to drive the user's real browser. Rather than
hand-writing browser tools, auto-register the (patched) chrome-devtools-mcp
as a session MCP server pointed at this daemon's /cdp endpoint, so its 29
ready-made DevTools tools flow through the tunnel.

- run-qwen-serve: forward QWEN_SERVE_CDP_TUNNEL_OVER_WS + _PORT into the
  spawned ACP child via childEnvOverrides (same path as the MCP budget env).
- acpAgent: buildCdpTunnelMcpServer() injects the server into the
  top-precedence sessionMcpServers tier when the flag + port are present and
  the package resolves; trust left unset so tools default to 'ask' (no silent
  auto-approval of browser control); best-effort skip otherwise.

No settings.json edit and no hand-written tools required.

* fix(serve): gate CDP bridge registration to the extension (#5626)

Auto-registering every /acp initialize as the CDP bridge was last-writer-
wins. Once an ACP agent connects over the same /acp endpoint (web UI, Zed),
it would capture the bridge and receive cdp_* frames it can't answer,
stealing the tunnel from the extension. Gate registration on
clientInfo.name === 'qwen-cdp-bridge'; the extension (and the acceptance
mock) now identify themselves that way, while agent clients are left alone.

* feat(extension): open the web UI when the toolbar icon is clicked

The extension has no UI of its own (pure CDP-tunnel pipe; chat lives in the
daemon web UI), so clicking the toolbar icon did nothing after the side panel
was removed. Wire action.onClicked to open the daemon baseUrl in a new tab so
the icon is a useful entry point instead of a dead click.

* feat: host the web UI in a Chrome side panel (#5626)

The extension is a pure CDP-tunnel pipe with no UI of its own, so after the
side panel chat was removed the toolbar icon did nothing. Bring the side panel
back as a thin host that iframes the daemon web UI (chat + tools), so the
sidebar is the everyday entry point and reuses the web UI's pages/components
instead of shipping a second UI in the extension.

- extension: side_panel + sidePanel permission; sidepanel.html/js frames the
  daemon baseUrl; toolbar icon opens the panel (openPanelOnActionClick).
- daemon: the Web Shell sent frame-ancestors 'none' + X-Frame-Options: DENY,
  which blocked the iframe. Allow framing only for chrome-extension origins
  explicitly passed via --allow-origin; everything else still gets DENY.

* fix: prefer chrome-devtools over computer-use under the CDP tunnel + keep MV3 worker alive during attach (#5626)

Two issues surfaced driving the real agent:

1. The agent picked the OS-level computer-use tool (cua-driver) for browser
   tasks instead of the injected chrome-devtools-mcp — heavyweight screenshot/
   click loop that pegged a CPU and stalled turns. Disable computerUse when the
   CDP tunnel flag is on so browser automation goes through the tunnel.

2. The extension's MV3 service worker idled out *between* CDP commands (the
   agent pauses to think), detaching chrome.debugger and hanging the next
   command. Add a sub-30s keepalive while attached; the 30s alarm only covered
   idle reconnects, not in-flight attachments.

* chore(extension): stop tracking .extension-key.pem (signing private key)

The extension signing private key was committed and pushed — anyone with repo
access could impersonate the extension. Stop tracking it and gitignore *.pem.
Load-unpacked debugging needs only the public "key" in manifest.json, so this
doesn't affect dev on any machine; the .pem is kept locally for packaging.

* refactor(chrome-extension): flatten to packages/chrome-extension

Drop the mcp-chrome-integration wrapper + dead native-server (daemon-direct
no longer uses native messaging). The extension is now a top-level workspace
at packages/chrome-extension. Updated root workspaces, eslint globs, doc-path
comments, and the two node scripts' global directives. cli + extension builds
and eslint verified green.

* test(serve): assert cdp_tunnel_over_ws in the capability registry

The cdp_tunnel_over_ws capability was added to SERVE_CAPABILITY_REGISTRY +
CONDITIONAL_SERVE_FEATURES but the test's EXPECTED_REGISTERED_FEATURES and the
conditional drift-insurance branch weren't updated, failing 3 registry tests.
Add it to the expected list (after client_mcp_over_ws, matching registry order)
and add its assertion branch (predicate accepts/rejects the cdpTunnelOverWsEnabled
toggle).

* fix(serve): address review comments on CDP tunnel + client-MCP wiring (#5777)

- guard post-async ws.send() with readyState OPEN (daemon crash on extension
  disconnect, sendClientMcpAck + cdp endpoint sends)
- make client-mcp-sender-registry delete() ownership-aware (cross-connection
  server-name collision)
- type the __clientMcpOverWs runtime config flag carrier
- document the CDP tunnel trust model (loopback + bridge-gated dumb pipe)

* chore(cdp-tunnel): set copyright year to 2026 on files created this year

The Plan C / #5626 files were authored in 2026 but carried a 2025 header.
service-worker.ts (created last year under #1432) keeps 2025.

* feat(chrome-ext): add side-panel onboarding gate + fix packaging

The side panel framed the daemon Web Shell unconditionally and showed a
static "Connecting…" line. When no daemon was reachable, or the daemon
wasn't started with --allow-origin (so frame-ancestors blocks the iframe),
the user was stuck on "Connecting…" with no guidance, and discovery.ts's
health check was never wired in.

Wire a health/capabilities gate into the panel:
- probe GET /health, then GET /capabilities
- down                         → "Start qwen serve" + the exact command
- up but no `allow_origin` feat → "Allow this extension" + the command
- ready                        → frame the Web Shell

The command is built from chrome.runtime.id at runtime, so it always names
this extension's real origin (dev-unpacked or published) — no need to know
or hardcode the id, and no publish-first chicken-and-egg. The pure decision
helpers live in onboarding-logic.js.

Also:
- fix `npm run package` so manifest.json sits at the zip root (the old
  `zip ... extension/` nested it under extension/, which the Chrome Web
  Store rejects)
- gitignore that packaging zip; add a package README

* fix(serve): address second-round review comments on the CDP tunnel (#5777)

- close the bound /cdp puppeteer socket on extension disconnect (was hanging
  ~170s on CDP timeout) via an onExtensionGone hook
- reject a 2nd concurrent /cdp client instead of silently clobbering routeInbound
- narrow extension host_permissions from <all_urls> to localhost (chrome.debugger
  needs no host perm; only the /health fetch needs localhost)
- log safeWsSend drops under serve debug mode so a dead tunnel is diagnosable

* feat(chrome-ext): polish side-panel welcome into a terminal console

Replace the bare welcome with a console that matches the product (a CLI
daemon): the command is the hero, typed at a `$` prompt with a blinking
cursor inside a titled terminal card. Warm-charcoal / electric-lime,
light + dark aware (prefers-color-scheme), staggered load-in, a pulsing
"listening" status, and a reduced-motion guard. No web fonts / no inline
JS (the extension CSP allows neither).

No behavior change: same /health + /capabilities gate and the
chrome.runtime.id-derived command. Mechanics tidied alongside the markup:
visibility toggles a .hidden class (CSS owns the flex layout), the copy
button updates a label span, and the command is prefilled synchronously
so first paint isn't an empty prompt.

* feat(chrome-ext): click-to-copy command + centered copy button

Make the onboarding command easier to grab: the whole command row is now
click-to-copy (keyboard-reachable, Enter/Space), and a centered "Copy
command" button sits at the foot of the terminal card. Both flash a
check-mark "Copied" confirmation; the small top-bar button is gone.

No gate-logic change. PR #5777.

* test(serve): cover CDP-tunnel + client-MCP regression guards

Add the four focused unit tests flagged in review for load-bearing
reverse-channel paths that had no coverage:

- ClientMcpSenderRegistry: ownership-scoped delete — a disconnecting
  connection must not remove an entry a peer re-registered under the
  same name.
- CdpTunnelRegistry: register/supersede/unregister lifecycle, inbound
  routing delegation, onExtensionGone-on-disconnect, and the
  stale-unregister guard that must not evict a newer active bridge.
- CdpReverseLink: a forwarded command rejects when its per-command
  timer expires (not just on bulk dispose).
- safeWsSend: drops (no send, no throw) on a CLOSED/CLOSING socket.

safeWsSend is extracted from acp-http/index.ts into its own module so
it's unit-testable in isolation; behavior unchanged.

Once the panel framed the Web Shell it stopped probing, so if the daemon
later went away the iframe was left showing Chrome's localhost

after a short tolerance (2 misses, ~5s, so a transient blip doesn't nuke a
live chat), clear the iframe src and show the welcome screen again.

* refactor(chrome-ext): inline onboarding helpers, drop dead pollTimer

onboarding-logic.js was a 65-line file (mostly JSDoc) for three trivial

Fold them into sidepanel.js (decideState collapses into probeState's
return; resolveBaseUrl/allowOriginCommand become a one-liner each) and

- cdp-bridge: only treat "already attached" as ours when attachedTabId === tabId

* fix(serve,chrome-ext): harden CDP-tunnel + client-MCP reverse channel

  disconnecting connection can't kill a server a later connection re-registered
  under the same name. (P2)
- service-worker: carry the bearer token via the `qwen-bearer.*` WS subprotocol
  (matching the web-shell + daemon decoder) instead of a `?token=` query the
  daemon never reads, so a token-gated daemon no longer 401-reconnect-loops. (P3)

  waiting for a cdp_attached that never arrives.
- acp-http: rename isFireAndForget -> dispatchOffQueue + clarify the comment;
  register/unregister are dispatched off-queue but still expect a response ack,

* fix(serve,cli): address #5777 review round 7

- config: warn (stderr) when QWEN_SERVE_CDP_TUNNEL_OVER_WS overrides an explicit
  tools.computerUse.enabled=true, so the effective config isn't a silent surprise.
- client-mcp-ws: document the intentional idempotency of handleUnregister.
- cdp-reverse-link: add tests for the attach gate — forwardToTab parks behind an
  in-flight attach, the cdp_attach timer rejects, and the gate opens on timeout
  so commands don't hang.

* fix(serve,core): address #5777 review round 8

- mcp-client: only treat the first stdio arg as a local entry script when
  it is clearly a filesystem path. A bare includes('/') also matched scoped
  npm package names (npx @scope/pkg), wrongly resolving them under the

- client-mcp-sender-registry: reject shadowedSettings so a browser-hosted
  WS client cannot shadow a user-configured MCP server name; roll back the
  child-side add.
- cdp-ws: close the puppeteer socket when /cdp attach fails so dispose()
  clears cdpBound/routeInbound, instead of a stuck tunnel until restart.
