+# Agent Configuration Model
+
+Use the smallest durable surface that matches the job.
+
+## Surfaces
+
+- `AGENTS.md`: auto-loaded repository entry point. Keep it small and reserve it for always-on rules, routing, and high-priority expectations.
+- `.agents/*.md`: human- and agent-readable reference docs linked from `AGENTS.md`. Use these for detailed project context, commands, architecture, and conventions.
+- `.agents/skills/*/SKILL.md`: repo-scoped Codex skills. Use these for repeatable workflows that should be discoverable by name and description.
+- `.codex/config.toml`: trusted project Codex settings such as MCP, hooks, sandbox, approval, or model defaults.
+- `.codex/rules/*.rules`: command permission rules for running commands outside the sandbox. Do not mix these with coding conventions in `.agents/rules.md`.
+- `.codex/hooks.json` or `.codex/config.toml` hooks: lifecycle automation such as prompt checks, command validation, or final verification gates.
+
+## Placement Rules
+
+- Put stable team conventions in `AGENTS.md` only when every task must see them without opening another file.
+- Put detailed explanations in `.agents/*.md` and link them from `AGENTS.md`.
+- Put reusable task workflows in `.agents/skills/<skill-name>/SKILL.md`.
+- Put mechanical enforcement in linters, tests, hooks, or `.codex/rules`; do not rely on prose when tooling can enforce the rule.
+- Keep user-specific preferences out of the repository. They belong in user-level Codex configuration or user-level skills.
+
+## Skill Authoring Rules
+
+- Use lowercase hyphenated names.
+- Start descriptions with `Use when...`.
+- Describe trigger conditions in the description, not the workflow.
+- Keep `SKILL.md` lean; link to `.agents/*.md` for large reference material.
+- Add scripts only when deterministic behavior is needed repeatedly.

+# Architecture
+
+## Core Integration
+
+The Go proxy core in `core/` operates in two modes.
+
+Android lib mode:
+
+- Go core is compiled as a C shared library, `libclash.so`, through `go build -buildmode=c-shared` with CGO.
+- The Android `:core` module owns JNI access to the in-process library. Flutter crosses the `${packageName}/service`
+  MethodChannel through `lib/plugins/service.dart` and Android's `ServicePlugin` rather than talking to JNI directly.
+- `lib/core/lib.dart` (`CoreLib`) implements the shared Core interface, gates method calls on its connection completer,
+  initializes and synchronizes Android shared state, and closes the native service path exactly once.
+- Because Core is in the application process on Android, application RSS already includes Core memory.
+
+Desktop core mode:
+
+- Go core runs as a separate process with `CGO_ENABLED=0`.
+- `rust_api` provides the native local-IPC primitives: a Unix domain socket on macOS/Linux and a named pipe on Windows.
+  Dart now owns the transport state, RPC correlation, process ownership, and lifecycle convergence above those primitives.
+- `lib/core/service.dart` (`CoreService`) is the composition root. It wires the IPC transport, launcher selection,
+  lifecycle controller, RPC client, and crash-event bridge; it is no longer the whole desktop implementation by itself.
+- `lib/core/desktop/transport.dart` converts native IPC frames into ready, connected, disconnected, failed, and data
+  events. A replaceable binding keeps RPC subscriptions stable when a failed or stale transport must be rebuilt.
+- `lib/core/desktop/rpc_client.dart` owns request IDs and pending completers, waits up to 10 seconds for a connection,
+  applies a three-minute default method timeout, unwraps `CoreMethodResponse`, and fails all pending calls when transport
+  disconnects or closes.
+- `lib/core/desktop/lifecycle.dart` serializes process intents and owns the authoritative desktop state machine.
+- `lib/core/desktop/launcher.dart` abstracts direct child-process and Windows Helper ownership through idempotent process
+  leases. `lib/core/desktop/helper_client.dart` is the typed loopback HTTP client for the privileged Helper.
+
+`lib/core/controller.dart` (`CoreController`) selects the implementation based on platform. `lib/core/interface.dart` defines the shared `CoreHandlerInterface`.
+
+Key Go core files:
+
+- `core/hub.go`: handler functions.
+- `core/method.go`: MethodChannel-style method-call dispatch and response envelopes.
+- `core/message.go`: non-blocking priority/bulk event queues and bounded message batching.
+- `core/lib.go`: CGO exports.
+- `core/server.go`: desktop socket/named-pipe client and framed message forwarding.
+
+## Lifecycle Ownership And Convergence
+
+### Shared Flutter Layer
+
+`CoreController.start()`, `restart()`, `stop()`, and `close()` are the only shared lifecycle facade. `close()` is terminal;
+callers must not try to reuse a closed platform implementation.
+
+`CoreAction` in `lib/providers/actions/core.dart` owns the user-facing Core status and setup sequence:
+
+- `startCore()` publishes `connecting`, starts the platform Core, publishes `connected`, then initializes Core state. A
+  startup error publishes `disconnected` and displays the error.
+- `restartCore()` coalesces overlapping callers behind one worker. `_requestedRestartRevision` records newer requests,
+  while `_latestExplicitStart` retains the newest requested post-restart running intent. After the lifecycle restart and
+  `initCore()`, the worker reapplies profile/running state until it has consumed the latest revision.
+- The provider is an orchestration and presentation layer, not a process owner. Platform lifecycle code remains responsible
+  for determining whether a Core process/service is actually running.
+
+Application exit is centralized in `SystemAction` and `SystemExitCoordinator`:
+
+1. Optionally save config and clean up DNS, system proxy, and tray resources in parallel.
+2. Close the desktop window.
+3. Call terminal `CoreController.close()`.
+4. Exit the application exactly once.
+
+The coordinator is idempotent, continues later cleanup steps after an earlier error, preserves the first error for the
+caller, and uses a three-second watchdog as an emergency application-exit path. `Application.dispose()` and
+`CoreManager.onCrash()` do not independently destroy Core; this avoids competing shutdown owners.
+
+### Desktop Lifecycle
+
+`DesktopCoreLifecycle` is a latest-desired-intent reconciler, not a queue that blindly executes every request:
+
+- Public intents receive monotonically increasing revisions and target running, restarted, stopped, or closed.
+- Observable phases are `idle`, `starting`, `running`, `stopping`, `failed`, and `closed`.
+- A completed command reports `applied`, `coalesced`, or `superseded`, allowing callers and tests to distinguish a command
+  that won from one satisfied or replaced by a newer compatible intent.
+- Startup opens or replaces the IPC transport, resolves a launcher, generates a 128-bit lowercase hexadecimal session ID,
+  launches Core, and waits for the matching connection. Windows additionally verifies that the named-pipe peer PID equals
+  the process PID returned by the Helper lease.
+- Each running session retains its process owner, lease, PID, session ID, and transport connection generation. Stop waits
+  for both process-exit confirmation and the matching disconnect generation; a missing disconnect replaces the transport
+  before later starts.
+- An unconfirmed process exit is retained as an unconfirmed lease. New start/restart intents fail until ownership can be
+  cleaned up, preventing two Core instances from being treated as the active session. Terminal close may continue on a
+  best-effort basis because the application is exiting.
+- An unexpected disconnect or transport failure while running is converted to `DesktopCoreFailure`, the owned process is
+  cleaned up, and `CoreService` emits a Core crash event for the normal UI recovery path.
+
+Direct launch is used on macOS/Linux and as the Windows fallback when the privileged Helper is not ready. When the Helper
+is ready on Windows, the Helper owns the Core child and Dart owns it through a session-scoped lease.
+
+### Android Service Lifecycle
+
+Android deliberately keeps Flutter requests optimistic and the native layer authoritative:
+
+- `ServicePlugin.start()` and `stop()` acknowledge immediately after submitting intent. They do not wait for service
+  creation, VPN permission, binding, TUN establishment, or teardown.
+- `ServiceState` owns the latest `RunRequest`, shared configuration, run time, and `STOPPED`/`STARTING`/`STARTED`/`STOPPING`
+  state. Identity checks discard obsolete work. `startPreparationLock` serializes permission/setup preparation and
+  `transitionLock` serializes actual service transitions.
+- `ServiceController` owns exactly one `ManagedServiceBinding`, selects `VpnService` or `ProxyService` from `VpnOptions`,
+  binds with a five-second connection timeout, invokes `ManagedService.start()`/`stop()` off the main thread, and clears
+  binding/run-time state on failure or disconnection.
+- Generic service creation/destruction is lifecycle evidence, not user intent. New commands must flow through
+  `ServiceState.requestStart()`/`requestStop()` or the explicit system-action handlers instead of inferring intent from a
+  callback.
+
+Quick Settings, notification, revoke, and Always-on VPN paths converge on the same owner:
+
+- With a Flutter engine attached, `ServiceState.handleStartAction()`/`handleStopAction()` forward through `TilePlugin` to
+  `TileManager`, which updates normal Flutter setup state. Without Flutter, native code restores `SharedState` from
+  preferences, runs `quickSetup`, checks VPN permission, and submits the native request directly.
+- Android may create an Always-on `VpnService` through `onStartCommand()` without FlClash's bound-service path. The service
+  sends the explicit, permission-protected `VPN_START_REQUESTED` broadcast to `ServiceBroadcastReceiver`, which routes it to
+  `ServiceState.handleStartAction()` so Core/configuration and the normal binding are restored before TUN is treated as
+  ready.
+- `VpnService.onRevoke()` stops TUN/modules first, then sends `VPN_REVOKED`; the receiver only requests a stop when
+  `ServiceController` still owns an active VPN binding.
+- `ServiceBroadcastReceiver` uses `goAsync()` and an atomic one-shot completion. Normal completion or a nine-second
+  watchdog calls `PendingResult.finish()` exactly once; the watchdog releases Android's broadcast lease and does not
+  cancel or redefine the underlying lifecycle intent.
+
+## Core Protocol And Event Delivery
+
+The shared protocol uses `CoreMethodCall(id, method, arguments)` and `CoreMethodResponse(id, result, error)` in both
+directions. The envelope is the only JSON serialization layer: keep arguments, results, and event data as structured JSON
+values rather than embedding pre-encoded JSON strings. Plain domain strings, such as country codes or provider contents,
+remain strings.
+
+Go event delivery is intentionally non-blocking:
+
+- State-bearing events such as delay, loaded-provider, and geo-update use a 256-entry priority queue. Desktop process
+  crashes are generated locally by `CoreService` from lifecycle failures rather than sent through the Go queue.
+- High-volume log and request/connection events use a separate 256-entry bulk queue, so bulk floods cannot evict state.
+- A full queue evicts only its own oldest event and retries the newest event; Core work never blocks on event delivery.
+- The batcher flushes at 32 messages or every 16 milliseconds. Priority events are preferred, but one bulk opportunity is
+  guaranteed after eight priority messages to prevent starvation.
+
+Desktop RPC accepts both a single event object and batched event lists. Android and desktop listener dispatch isolate
+listener exceptions so one faulty observer does not prevent the remaining events/listeners from running.
+
+## User-Facing Core And Delay Feedback
+
+`CoreStatusButton` in `lib/views/dashboard/widgets/core_status_button.dart` is the desktop dashboard's status/restart
+surface. It is shown only outside dashboard edit mode and only when `coreLib == null`:
+
+- Provider state remains authoritative. The widget keeps a separate display-only status so a fast
+  `connecting -> connected` transition still shows at least 600 milliseconds of progress instead of flashing.
+- The hold arms only after an observed transition to `connecting`; mounting while already connecting does not invent a new
+  delay. A real `disconnected` transition cancels the hold immediately so failure is never hidden, while a long-running
+  connecting state remains visible after the timer expires.
+- Taps during the display hold or while the provider is genuinely connecting are inert. Connected/disconnected taps show
+  the appropriate confirmation and delegate restart to `CoreAction`; the widget never starts Core directly.
+
+Proxy delay testing follows the same failure-safe UI rule. `proxyDelayTest()` records an in-progress zero delay, writes the
+real result on success, and logs plus records `-1` on exceptions. `DelayTestButton` reverses its animation in `finally`, so
+an RPC failure cannot leave the control permanently spinning.
+
+## State Management
+
+Provider files in `lib/providers/`:
+
+- `app.dart`: runtime/UI state, logs, traffic, delays, loading, navigation.
+- `config.dart`: persistent config providers, app settings, theme, VPN, proxy style.
+- `state.dart`: derived/computed providers, navigation, proxy, tray, color scheme.
+- `action.dart`: business logic notifiers, setup, backup, core lifecycle, proxy selection.
+- `database.dart`: Drift database provider wrappers.
+
+`globalState` in `lib/state.dart` is a singleton holding app lifecycle, timers, theme, and start/stop state. Providers are generated into `lib/providers/generated/`.
+
+## Database
+
+The app uses Drift/SQLite in `lib/database/`. Current schema version is 2.
+
+Tables:
+
+- `Profiles`
+- `Scripts`
+- `Rules`
+- `ProfileRuleLinks` (`profile_rule_mapping`)
+- `ProxyGroups`
+- `IconRecords` (`icon_records`)
+
+Rule scenes distinguish global added rules, profile added rules, profile custom rules, and disabled links. Rule and proxy-group ordering use fractional indexing.
+
+Generated Drift output lives in `lib/database/generated/database.g.dart`. After schema changes, run code generation and add or update focused database tests under `test/database/` when converter or migration behavior changes.
+
+## Manager Stack
+
+Managers are nested `InheritedWidget`/`StatefulWidget` components in `lib/application.dart`:
+
+```text
+AppEnvManager > StatusManager > ThemeManager
+  > [Desktop: WindowManager > TrayManager > HotKeyManager > ProxyManager]
+  > ConnectivityManager > CoreManager > AppStateManager
+  > [Mobile: AndroidManager > VpnManager | Desktop: WindowHeaderContainer]
+```
+
+Each manager in `lib/manager/` handles a specific platform concern. Desktop-only managers are conditionally inserted.
+
+## Core Controller and Actions
+
+`lib/core/controller.dart` (`CoreController`) is a singleton facade over `CoreHandlerInterface`. Public methods delegate to the platform-specific interface, either Android FFI or desktop socket. It has an `@visibleForTesting` constructor and `resetInstance()` for test injection.
+
+`lib/providers/action.dart` is the public library entry point for action
+providers. The Riverpod notifier implementations are split by responsibility
+under `lib/providers/actions/` and joined to the entry point with `part`
+directives, so consumers continue to import the same public API:
+
+- `CommonAction`: update check and common UI operations.
+- `SetupAction`: config setup and TUN management.
+- `BackupAction`: backup/restore with WebDAV sync.
+- `CoreAction`: core lifecycle, initialization, coalesced restart, and post-restart profile/running-state application.
+- `SystemAction`: system integration, tray, coordinated resource cleanup, terminal Core close, exit, and brightness.
+- `StoreAction`: profile storage operations.
+- `ThemeAction`: theme state updates.
+- `ProxiesAction`: group management and proxy selection.
+- `ProfilesAction`: profile CRUD, auto-update, import.
+- `GeoResourceAction`: geo resource updates and URL configuration.
+
+## Platform Managers
+
+Desktop:
+
+- `WindowManager`
+- `TrayManager`
+- `HotKeyManager`
+- `ProxyManager`
+
+Mobile:
+
+- `AndroidManager`
+- `TileManager`
+- `VpnManager`
+
+Shared:
+
+- `ConnectivityManager`
+- `CoreManager`
+- `AppStateManager`
+- `StatusManager`
+- `ThemeManager`
+
+## Build System
+
+`setup.dart` is the release build orchestrator:
+
+1. Writes `env.json` (`APP_ENV`).
+2. Activates `flutter_distributor` for packaging.
+3. Relies on the platform build hook to build the required Core artifacts before
+   the native application is linked.
+
+Go core building is handled by `build_tool`, a standalone Dart CLI in `plugins/setup/buildkit/build_tool/`.
+
+Platform build hooks inside `flutter build` trigger `build_tool` automatically:
+
+- macOS: podspec script phase, `build_pod.sh`, `build_tool macos`.
+- Linux: CMake include, `buildkit/cmake/buildkit.cmake`, `build_tool linux`.
+- Windows: CMake include, `buildkit/cmake/buildkit.cmake`, `build_tool windows`. CMake forwards the active configuration through `BUILDKIT_CONFIGURATION`.
+- Android: Gradle include, `buildkit/gradle/plugin.gradle`, `build_tool android`.
+
+### Setup Build Harness Plugin
+
+`plugins/setup/` is a build-time Flutter plugin, not a runtime Dart or FFI API. Its plugin shape exists so Flutter's native
+build graphs can run the Go/Rust build harness before platform consumers need the generated artifacts. Application code
+must not import or call it.
+
+Responsibilities are deliberately split:
+
+- CocoaPods, Gradle, and CMake hooks schedule a lightweight check on every native build. They do not decide which Go or
+  Rust files are stale.
+- `buildkit/build_tool/` owns target resolution, input fingerprinting, compilation, output copying, and cache validation.
+- `core/` and `services/helper/` remain source owners; `libclash/` and Android `jniLibs`/header directories are generated
+  output locations.
+- `setup.dart` remains the release/package orchestrator and does not pre-build
+  platform artifacts or use `dart-define` for Core integrity data. The Windows
+  build tool writes the runtime `manifest.json` beside the Core output, and the
+  Windows bundle copies it beside the application executable.
+
+Platform outputs remain explicit:
+
+- Android builds the Go core as `c-shared`, then copies `libclash.so` and generated headers into the `:core` Android module.
+- macOS and Linux build a standalone `FlClashCore` process used by the desktop socket integration.
+- Windows builds `FlClashCore.exe`, the Rust `FlClashHelperService.exe` privileged helper, and a
+  `manifest.json` containing only `coreSha256`.
+
+The hooks follow rust_api/Cargokit's phony-output scheduling pattern, but setup uses its own cache because it builds both a
+Go core and, on Windows, a separate Rust helper. Per-target records live under `.dart_tool/setup_build_cache/v1/`:
+
+- Go fingerprints cover the target-specific `go list -deps` inputs inside `core/` and `Clash.Meta`, module files, effective
+  build configuration, build-tool sources, target flags, Go environment/toolchain, and Android NDK compiler details.
+- Windows helper fingerprints cover its Rust sources and manifests, Cargo/Rust
+  toolchains and flags, and the expected Core SHA256.
+- A cache hit requires the fingerprint and every recorded output's path, size, and modification state to match. It exits
+  silently without Go/Cargo compilation, output copying, or Windows `taskkill`.
+- Cache records are written only after a successful build and protected by per-target process/file locks. Missing outputs,
+  changed inputs, cache-schema changes, or `--force` rebuild only the affected target.
+- `flutter clean` removes `.dart_tool`, so the next native build performs one full core rebuild. Manual builds can bypass
+  the cache with `make core-<platform> FORCE=1`.
+
+This differs from `rust_api`: rust_api is a runtime Flutter Rust Bridge integration whose Cargokit hooks produce its native
+FFI library, while setup is only the build and packaging bridge for FlClash's external core artifacts.
+
+Windows helper integrity/version check:
+
+- The build tool constructs the Core first, calculates its SHA256, and always
+  builds the Rust Helper with release hardening and that expected hash.
+- Flutter reads the Core SHA256 from the bundled `manifest.json` and sends it with `/ping`. Debug, Profile, and Release
+  builds use the same Helper protocol and may use TUN through the same flow.
+- `/ping` is loopback-only and requires no request token. The Helper compares the requested SHA256 with its embedded value
+  and checks that the fixed `FlClashCore.exe` beside it exists; `/start` performs the actual Core SHA256 verification before
+  every launch. The response includes the running Helper path and protocol header; Dart checks both against the current
+  installation. The launcher selects the Helper only when `/ping` reports ready; any other readiness (missing manifest,
+  unavailable Helper, or a Helper built for a different Core) falls back to the direct Core without requesting elevation.
+  If `/start` reports a pre-spawn failure — `coreVerificationFailed` (the on-disk Core no longer matches the SHA the
+  Helper and manifest agree on) or `processLaunchFailed` (the Core process could not be spawned) — the launcher degrades
+  to the direct Core rather than failing the launch. `/start` releases the previously managed Core before it verifies,
+  so the Helper owns no Core when either code is reported and the direct retry cannot race a Helper-managed Core.
+  A mismatched Helper is reinstalled through the explicit TUN authorization flow, not at startup.
+- TUN is not a required run condition. A direct Core runs unelevated and cannot bring up TUN, so any degrade to the
+  direct Core — an unready Helper at resolve time, or a pre-spawn `/start` failure — silently drops TUN and keeps the
+  Core running. Degrading is preferred over failing the launch: an unverified Core carries no privilege the direct
+  launch path did not already have. `manifestMissing` is the one readiness that is surfaced to the user, because it
+  means the installation itself is incomplete.
+- Flutter creates a 128-bit lowercase-hex session ID and uses it as the random named-pipe suffix. `/start` receives only
+  that address and session ID, validates the fixed `FlClashCore_<session>` namespace, starts the fixed Core beside the
+  Helper, and returns the same session ID plus the spawned PID. Flutter verifies both the session and named-pipe peer PID.
+- `/stop` requires the same session ID. A missing process returns `notRunning`; a different owner returns
+  `sessionMismatch` without terminating that process. Session IDs are ownership tokens for lifecycle safety, not a claim
+  that the loopback HTTP endpoints are authenticated.
+
+Build configuration defaults live in `build_tool/lib/src/options.dart` and can be overridden via a root `build_config.yaml`.
+
+Architecture detection is automatic. The `--description` flag passed to `flutter_distributor` adds arch suffixes to artifact names, such as `FlClash-0.8.93-macos-arm64.dmg`.
+
+## Local Plugins
+
+- `setup`: build-time harness for Go core artifacts and the Windows Rust helper; no runtime Dart API.
+- `proxy`: system proxy configuration.
+- `rust_api`: runtime Flutter Rust Bridge FFI plugin built through Cargokit.
+- `tray_manager`: system tray fork/customization.
+- `wifi_ssid`: Wi-Fi SSID detection.
+- `window_ext`: window extensions.
+- `flutter_distributor`: app packaging/distribution.
+
+## Rust Helper Service
+
+`services/helper/` is a Windows-only privileged helper for starting the core as admin and managing TUN. It is built with:
+
+```bash
+make core-windows
+```
+
+The build tool always compiles the Helper in Rust release mode after calculating
+the SHA256 of the Core produced for the active Flutter configuration.
+
+The helper owns its Windows Service Control Manager lifecycle through two elevated commands:
+
+- `FlClashHelperService.exe install` stops and removes any stale registration, creates the auto-start service for the
+  current executable path, starts it, and waits for the running state.
+- `FlClashHelperService.exe uninstall` stops the service, waits for shutdown, removes its registration, and is also used
+  by the Windows package uninstaller.
+
+The Dart layer only launches the helper's `install` command through `ShellExecuteW`; it does not compose `sc.exe`,
+`taskkill`, or `cmd.exe` command lines.
+
+In every Flutter build mode `/start` opens the fixed Core executable beside the Helper without write/delete sharing,
+validates it against the SHA256 embedded only in the Helper, and keeps that handle open through process creation.
+`/ping` only compares the requested `coreSha256` with the Helper's embedded value and checks the fixed Core path exists;
+it never hashes the Core. Protocol version 6 uses 32-character lowercase-hex session ownership:
+
+- `GET /ping?coreSha256=...` returns the current Helper executable path with `x-flclash-helper-protocol` when the
+  requested SHA matches.
+- `POST /start` rejects unknown JSON fields, validates `{address, sessionId}`, then releases any previously managed Core
+  before verifying the Core — so every outcome, including a rejected one, leaves the Helper owning no Core — and returns
+  `{sessionId, pid}`.
+- `POST /stop` validates `{sessionId}` and only stops the matching managed Core. A session mismatch is HTTP 409.
+- `GET /logs` exposes the bounded recent Helper/Core stderr buffer with `no-store` caching.
+
+All endpoints bind only to `127.0.0.1:47890` and do not use request-token authentication. Lifecycle safety comes from the
+fixed executable/hash, strict pipe namespace, session-scoped stop contract, and Dart-side peer-PID verification. When the
+Helper service itself shuts down, it unconditionally stops the Core process it owns.

+# Commands
+
+## Building
+
+Update submodules first. The ClashMeta Go core lives in `core/Clash.Meta/`.
+
+```bash
+git submodule update --init --recursive
+```
+
+Full package build, including Go core, Flutter, and packaging, runs through `setup.dart`:
+
+```bash
+dart setup.dart macos
+dart setup.dart linux
+dart setup.dart windows
+dart setup.dart android
+```
+
+Build only the Go core and skip Flutter packaging:
+
+```bash
+make core-macos
+make core-linux
+make core-windows
+make core-android
+```
+
+Pass `ARCH` or `TARGET_PLATFORM` through `make` when needed, for example:
+
+```bash
+make core-macos ARCH=arm64
+make core-android TARGET_PLATFORM=android-arm64
+```
+
+Core builds use setup's input fingerprint cache. Pass `FORCE=1` to bypass it,
+for example `make core-macos ARCH=arm64 FORCE=1`.
+
+The Makefile wraps `plugins/setup/buildkit/run_build_tool.sh`; prefer the `make` entry points unless debugging the build tool itself.
+
+## Flutter Development
+
+Use the default Flutter SDK directly:
+
+```bash
+flutter pub get
+flutter run
+flutter test
+```
+
+Use `flutter test`, not `dart test`, because models pull in Flutter types.
+
+## Code Generation
+
+Run code generation after modifying models, providers, or database schema:
+
+```bash
+dart run build_runner build --delete-conflicting-outputs
+dart run build_runner watch
+```
+
+Code generation covers:
+
+- Riverpod providers through `riverpod_generator`.
+- Models through `freezed` and `json_serializable`.
+- Database tables through `drift_dev`.
+
+Generated output paths, configured in `build.yaml`:
+
+- `lib/models/generated/*.g.dart`, `*.freezed.dart`.
+- `lib/providers/generated/*.g.dart`.
+- `lib/database/generated/*.g.dart`.
+
+## Testing
+
+Tests use `package:test/test.dart` for pure Dart logic and `flutter_test` for provider and widget tests. `mocktail` is the mocking framework.
+
+```bash
+flutter test test/models/
+flutter test test/core/
+flutter test test/core/desktop/
+flutter test test/providers/
+flutter test test/common/
+flutter test test/database/
+flutter test test/widgets/
+flutter test test/setup_test.dart
+flutter test plugins/proxy/test/proxy_test.dart
+```
+
+Root `flutter test` only discovers the root package's `test/` directory by default. Include bundled plugin Dart tests by passing paths explicitly, or run `flutter test` from that plugin package directory. Native plugin tests under platform folders are not run by `flutter test`.
+
+For the current Core/service architecture, useful focused checks are:
+
+```bash
+flutter test test/core/desktop/
+flutter test test/core/service_test.dart
+flutter test test/core/protocol_contract_test.dart
+flutter test test/manager/core_manager_test.dart
+flutter test test/providers/action_test.dart test/providers/system_action_test.dart
+flutter test test/widgets/core_status_button_test.dart
+```
+
+What those suites own:
+
+- `test/core/desktop/`: replaceable IPC transport, RPC request correlation/failure, direct/Helper process leases, and
+  latest-intent desktop lifecycle convergence.
+- `test/core/service_test.dart`: `CoreService` composition and terminal close behavior.
+- `test/core/protocol_contract_test.dart`: shared Dart/Go method and event-envelope compatibility, including event batches.
+- `test/providers/action_test.dart`: Core start/restart orchestration and overlapping restart requests.
+- `test/providers/system_action_test.dart`: ordered, idempotent exit cleanup and watchdog behavior.
+- `test/widgets/core_status_button_test.dart`: 600-millisecond connecting presentation hold, immediate failure display,
+  long-running connecting state, and disconnected restart.
+
+## Native Component Verification
+
+The CI Go-wrapper checks can be reproduced without CGO:
+
+```bash
+cd core
+CGO_ENABLED=0 go test .
+CGO_ENABLED=0 go vet .
+```
+
+The Windows Helper's loopback/session protocol tests are host-independent by default. Windows CI additionally enables its
+service implementation:
+
+```bash
+cargo fmt --manifest-path services/helper/Cargo.toml -- --check
+cargo test --manifest-path services/helper/Cargo.toml
+cargo test --manifest-path services/helper/Cargo.toml --features windows-service
+```
+
+The last command requires Windows for meaningful service coverage. Native Android lifecycle edits should at minimum
+compile the modules they touch; use JDK 17 in this checkout:
+

+
+Always-on VPN entry, system VPN revoke, actual permission UI, and rapid device start/stop still require Android device or

+## Verify
+
+The tag-triggered release workflow runs these root-package checks in order:
+
+```bash
+flutter pub get
+flutter analyze --no-fatal-infos
+flutter test --reporter expanded
+```
+
+Run `flutter analyze` locally before committing when practical.
+
+The workflow runs only for `v*` tag pushes; pull requests do not trigger it.
+Root analysis excludes `plugins/**`, and root tests do not discover nested
+plugin packages, so CI also validates local Flutter packages, the setup build
+tool, the Go wrapper, and Rust components from their own package directories. A
+separate Windows runner compiles and tests the helper's `windows-service`
+feature before release builds can start.

+# Project Context
+
+FlClash is a multi-platform proxy client based on ClashMeta (mihomo), built with Flutter. It supports Android, Windows, macOS, and Linux, using a Material You design with Surfboard-like UI.
+
+## Version Notes
+
+- Release CI pins Flutter 3.44.4. Local SDK may diverge, so trust the CI
+  version as the source of truth for release builds.
+- Dart SDK constraint: `>=3.8.0 <4.0.0`.
+
+## Build Dependencies
+
+Linux:
+
+```bash
+sudo apt-get install libayatana-appindicator3-dev libkeybinder-3.0-dev
+```
+
+Windows:
+
+- GCC and Inno Setup.
+- `ANDROID_NDK` env var for Android builds.
+
+macOS:
+
+```bash
+npm install -g appdmg
+```

+# Rules
+
+These are repository coding and testing conventions. Codex command permission rules belong in `.codex/rules/*.rules`; see `.agents/agent-config.md` before adding those.
+
+## Dart and Flutter Style
+
+`analysis_options.yaml` enforces these non-default rules:
+
+- `prefer_single_quotes: true`: always use single quotes.
+- `require_trailing_commas: true`: use trailing commas in multi-line argument lists.
+- `sort_child_properties_last: true`: `child:` must be the last named parameter.
+- `avoid_print: true`: do not use `print()` calls.
+- `prefer_const_constructors: true` and `prefer_const_declarations: true`.
+- `prefer_final_locals: true` and `prefer_final_in_for_each: true`.
+- `always_declare_return_types: true`.
+
+Generated directories are excluded from analysis:
+
+- `build/**`
+- `lib/l10n/intl/**`
+- `lib/**/generated/**`
+- `plugins/**`
+
+## Core API Safety
+
+- Do not expose direct filesystem deletion APIs through Core or helper IPC; use
+  a scope-specific cleanup API instead.
+- Keep the shared `CoreMethodCall`/`CoreMethodResponse` JSON envelope structurally identical across Dart, Go, JNI, and
+  desktop IPC. Do not double-encode `arguments`, `result`, or event batches.
+- Keep high-volume log/request events separate from state-bearing events in `core/message.go`; bulk backpressure must not
+  evict delay, loaded-provider, or geo-update state.
+
+## Lifecycle Rules
+
+- Desktop process ownership belongs to `DesktopCoreLifecycle`; do not start/kill `FlClashCore` from providers, widgets,
+  managers, or ad hoc exit callbacks. Acquire and release it through a `CoreProcessLease`.
+- `CoreController.close()` and platform `close()` implementations are terminal and idempotent. Application shutdown must
+  stay centralized in `SystemAction`/`SystemExitCoordinator`.
+- Android start/stop MethodChannel calls are optimistic UI commands. Keep latest-wins arbitration in native
+  `ServiceState`; do not add a Flutter completion callback that creates a second lifecycle owner.
+- Android service callbacks are not automatically user intent. Route explicit Quick Settings, Always-on VPN, and revoke
+  actions through `ServiceState` and keep `ServiceController` as the sole binding/run-time owner.
+- Every `BroadcastReceiver.goAsync()` path must finish its `PendingResult` exactly once. A watchdog may release the
+  broadcast lease, but must not cancel, reverse, or otherwise redefine the service operation.
+- Presentation smoothing such as `CoreStatusButton`'s connecting hold must remain local display state. It must not delay or
+  overwrite `coreStatusProvider`, and a real failure must bypass/cancel the hold immediately.
+
+## Testing Rules
+
+The `core/` directory is excluded from automated coverage accounting. Do not add coverage instrumentation or coverage
+collection for code under `core/`. CI still runs `CGO_ENABLED=0 go test .` and `go vet .` to compile/check the Go wrapper;
+verify cross-language protocol behavior through shared Dart contract tests under `test/core/` and native platform build
+checks.
+
+Use `CoreController.test(mock)` to inject a mocked `CoreHandlerInterface`. Call `CoreController.resetInstance()` in `tearDown` to clean up the singleton between tests.
+
+Register fallback values for freezed params used with `any()` matchers.
+
+Use `ProviderContainer` directly for simple Riverpod provider tests. The generated Riverpod `update()` method takes a callback:
+
+```dart
+notifier.update((state) => newValue);
+```
+
+When testing freezed models with nested objects, always round-trip through `jsonEncode` and `jsonDecode`. Direct `fromJson(toJson())` fails for nested freezed types because `toJson()` stores child objects directly instead of maps.
+
+For async widgets, put visual cleanup in `finally` when the action may throw. Focused widget tests should cover success,
+failure, disposal, and any timer boundary that changes visible state.
+
+## Generated Code
+
+Do not manually edit generated files under:
+
+- `lib/l10n/l10n.dart`
+- `lib/models/generated/`
+- `lib/providers/generated/`
+- `lib/database/generated/`
+- `lib/l10n/intl/`
+
+After schema, model, or provider changes, run build generation and include focused tests when behavior changes.

+
+# Core And Platform
+
+## When To Use
+
+Use this for changes touching `lib/core/`, `lib/manager/`, `core/`, `services/helper/`, Android app/service modules, build
+hooks, system proxy, tray, VPN, TUN, or platform-specific desktop/mobile behavior.
+
+## Workflow
+
+1. Identify the authoritative owner before changing behavior:
+   - Shared facade/protocol: `lib/core/controller.dart`, `lib/core/interface.dart`, and `lib/core/method.dart`.
+   - Android Core connection: `lib/core/lib.dart`, `lib/plugins/service.dart`, and Android `ServicePlugin`.
+   - Android start/stop intent: `ServiceState`; binding/process-time bookkeeping: `ServiceController`.
+   - Desktop composition: `lib/core/service.dart`; lifecycle/process ownership: `lib/core/desktop/lifecycle.dart`.
+   - Desktop IPC/RPC: `lib/core/desktop/transport.dart` and `lib/core/desktop/rpc_client.dart`.
+   - Desktop launch ownership: `lib/core/desktop/launcher.dart`; Windows Helper HTTP contract:
+     `lib/core/desktop/helper_client.dart` and `services/helper/`.
+   - Flutter orchestration: `lib/providers/actions/core.dart` and `system.dart`; UI/event observation: `lib/manager/`.
+2. Trace every entry path into that owner, including UI/provider calls, Quick Settings, notification actions, Always-on VPN,
+   revoke callbacks, application exit, and crash/disconnect recovery. Lifecycle callbacks are not implicit user intent.
+3. Preserve latest-intent semantics:
+   - Desktop revisions converge to running/restarted/stopped/closed and report applied/coalesced/superseded outcomes.
+   - Android Flutter calls stay optimistic; `ServiceState` identity-checks the latest native `RunRequest`.
+4. Route feature calls through `CoreController` and `CoreHandlerInterface`. Do not bypass desktop process leases or create a
+   second Android service binding owner.
+5. Keep JSON envelopes and event shapes identical across Dart, Go, JNI, and desktop IPC. If event traffic changes, preserve
+   the separate priority and bulk queues in `core/message.go`.
+6. Keep shutdown single-owned and terminal. `SystemExitCoordinator` sequences resource cleanup, window close, Core close,
+   and process exit; widget/manager disposal must not race it.
+7. Add or update focused tests at the narrowest layer, then run the matching commands from `.agents/commands.md`:
+   - Desktop lifecycle/transport/RPC: `test/core/desktop/` plus `test/core/service_test.dart`.
+   - Cross-language envelopes/events: `test/core/protocol_contract_test.dart` and `CGO_ENABLED=0 go test .`.
+   - Provider/exit convergence: `test/providers/action_test.dart` and `test/providers/system_action_test.dart`.
+   - Android Kotlin: compile each touched Gradle module with JDK 17.
+   - Windows Helper: Cargo format/tests; run the `windows-service` feature on Windows.
+8. Explicitly state host gaps. Always-on VPN, VPN permission, system revoke, named-pipe peer identity, and Windows Service
+   Control Manager behavior need their real platform even when portable tests pass.
+
+## Reference Files
+
+Read `.agents/architecture.md` for the current core modes, manager stack, build hooks, local plugins, and Windows helper notes.
+
+## Pitfalls
+
+- Keep the Windows Helper protocol and Core SHA256 validation identical across
+  Flutter build modes; the Helper owns executable integrity checks.
+- Protocol version 6 uses a 32-character lowercase-hex session ID. `/start` must return the submitted session and PID;
+  `/stop` must never terminate a different session; Dart must verify the connected named-pipe peer PID.
+- `/start` must release the previously managed Core before it verifies, so no `/start` outcome leaves a Helper-managed
+  Core behind for the caller's direct-launch fallback to race.
+- The Helper owns a managed Core until its exit is confirmed. A `200` from `/stop` means the Core is gone; when
+  termination cannot be confirmed the Helper keeps the child and answers `coreStopFailed`, and `/start` reports the same
+  code instead of spawning a replacement. Keep that code out of the Dart pre-spawn fallback set in
+  `helper_client.dart`, or the direct launch will race a Core the Helper still owns.
+- TUN is not a required run condition. Degrading to the unelevated direct Core — and silently losing TUN — is the
+  expected outcome whenever the Helper path fails; do not fail the launch instead.
+- A desktop process lease with unconfirmed exit must remain owned until cleanup succeeds. Do not discard it and start a
+  replacement Core.
+- `CoreController.close()` is terminal. Do not call it from a reusable manager lifecycle or recover by starting it again.
+- `ServiceBroadcastReceiver.goAsync()` must finish once even on timeout; its watchdog releases the broadcast only and must
+  not become a service timeout.
+- Do not interpret service creation/destruction as start/stop intent. Always-on startup is explicit through
+  `VPN_START_REQUESTED`; revoke is explicit through `VPN_REVOKED`.
+- Keep log/request floods from evicting state-bearing Core events. Each queue may evict only its own oldest item.
+- Do not expose direct filesystem deletion APIs through Core or helper IPC; use
+  a scope-specific cleanup API instead.
+- `plugins/setup/` is a build harness, not a Dart API plugin.
+- Build hooks can trigger Go or Rust compilation indirectly through Flutter platform builds.

+description: Use when changing FlClash UI text, scanning for hardcoded Chinese strings, updating ARB localization, or fixing generated locale output in this repository.
+---
+
+# Localization
+
+## When To Use
+
+Use this for localization work inside `/Users/Shared/follow/FlClash`, especially hardcoded UI text in `lib/`, ARB updates, missing translations, or generated `lib/l10n/` output that does not match source ARB values.
+
+Do not use this for README translation sync or manual edits to generated localization Dart.
+
+## Workflow
+
+1. Confirm `pubspec.yaml` still uses `flutter_intl`, source ARBs under `arb/`, and generated output under `lib/l10n/`.
+2. Scan user-facing Dart text before opening many files:
+
+   ```bash
+   rg -n "[\\p{Han}]" lib -g '!lib/l10n/intl/**' -g '!lib/**/generated/**'
+   ```
+
+3. Inspect the smallest relevant call sites and nearby ARB keys.
+4. Add or update every source ARB:
+   - `arb/intl_en.arb`
+   - `arb/intl_zh_CN.arb`
+   - `arb/intl_ja.arb`
+   - `arb/intl_ru.arb`
+5. Replace inline strings with existing project accessors:
+   - Widgets with `BuildContext`: `context.appLocalizations.key` from `common.dart`.
+   - Controllers/providers/non-widget code: `currentAppLocalizations.key` from `app_localizations.dart`.
+6. Regenerate:
+
+   ```bash
+   dart run intl_utils:generate
+   ```
+
+7. Verify changed Dart files with `flutter analyze` when practical.
+8. Re-run the Han-text scan for targeted strings.
+
+## Pitfalls
+
+- If ja/ru still show English, fix ja/ru source ARB values and regenerate. Do not edit generated Dart.
+- Ignore `lib/l10n/intl/**` and `lib/**/generated/**` during text scans.
+- If generator or analyzer hits local cache permission friction, rerun serially before treating it as a code issue.

+# Provider Tests
+
+## When To Use
+
+Use this for tests under `test/providers/` or any change that validates Riverpod providers, generated notifiers, app state defaults, or provider interactions.
+
+For broader test expansion, pair this with `.agents/rules.md` and `.agents/commands.md`.
+
+## Workflow
+
+1. Read the provider under test and its generated public API before writing assertions.
+2. Use `ProviderContainer` directly when no widget tree is needed.
+3. Dispose containers in teardown or with `addTearDown(container.dispose)`.
+4. Prefer generated notifier APIs over implementation details. Generated `update()` takes a callback:
+
+   ```dart
+   notifier.update((state) => newValue);
+   ```
+
+5. Mock external dependencies with `mocktail`; register fallback values for freezed params used with `any()`.
+6. Keep tests focused on behavior: defaults, state transitions, persistence boundaries, and side effects.
+7. Run the narrowest relevant test first:
+
+   ```bash
+   flutter test test/providers/
+   ```
+
+## Pitfalls
+
+- Do not use `dart test`; FlClash models and provider tests may depend on Flutter types.
+- Re-check source defaults before asserting them; provider defaults can drift.
+- If async provider timing matters, wait on provider futures or state changes instead of fixed sleeps.

+# UI Work
+
+## When To Use
+
+Use this for user-facing Flutter UI changes in `lib/`, including widgets, screens, navigation surfaces, settings rows, dialogs, and interaction behavior.
+
+## Workflow
+
+1. Locate existing nearby widgets and reuse their patterns before adding new abstractions.
+2. Follow current Material You and Surfboard-like visual conventions.
+3. Use existing providers, notifiers, and helpers where possible.
+4. Keep `child:` last in widget constructors.
+5. Prefer `const` constructors and final locals.
+6. Localize user-facing text through ARB; use `localization` when text changes are non-trivial.
+7. Add focused widget tests when behavior changes, especially for rendering states, taps, scrolling, and empty/error states.
+8. For asynchronous controls, define separately:
+   - authoritative provider/domain state;
+   - display-only state such as a minimum progress duration;
+   - tap policy while work or display holds are active;
+   - failure/disposal cleanup, normally in `finally` for animations and timers.
+9. Run targeted verification:
+
+   ```bash
+   flutter analyze
+   flutter test test/widgets/
+   ```
+
+## Pitfalls
+
+- Do not introduce a new visual system for one screen.
+- Do not manually edit generated localization or provider files.
+- Avoid broad layout rewrites unless the requested change requires them.
+- Do not mutate provider/domain state merely to smooth a transition. Keep presentation holds local and let real errors
+  bypass them immediately.
+- Do not leave loading animations active when callbacks throw. Test the exception path, not only the successful tap.
+
+## Current Interaction Examples
+
+- `CoreStatusButton` watches `coreStatusProvider` but keeps its 600-millisecond connecting hold locally. Taps are ignored
+  during the hold or genuine connecting state; disconnected cancels the hold immediately.
+- Proxy delay testing writes `0` while pending, the measured delay on success, and `-1` on failure. `DelayTestButton` resets
+  its animation in `finally`.

+# AGENTS.md
+
+This file is the entry point for AI coding agents working in this repository. Keep it small: detailed guidance lives under
+`.agents/`, and discoverable repo skills live under `.agents/skills/*/SKILL.md`.
+
+## Start Here
+
+Read these files before making changes:
+
+- [.agents/project.md](.agents/project.md): project overview, versions, and build dependencies.
+- [.agents/commands.md](.agents/commands.md): build, development, code generation, and test commands.
+- [.agents/rules.md](.agents/rules.md): lint, testing, generated-code, and workflow rules.
+
+Read these only when the task touches their area:
+
+- [.agents/architecture.md](.agents/architecture.md): core integration, providers, database, managers, build system, and
+  local plugins.
+- [.agents/agent-config.md](.agents/agent-config.md): how to choose between `AGENTS.md`, `.agents`, skills, Codex config,
+  command rules, and hooks.
+- [.agents/skills.md](.agents/skills.md): index of repo-scoped skills in `.agents/skills/`.
+
+## Highest Priority Rules
+
+- When the user explicitly requests a scoped, low-risk change, inspect the relevant context and implement it directly.
+  Do not require brainstorming, design documents, implementation plans, multiple-option proposals, or repeated confirmation.
+  Ask only when material ambiguity, destructive impact, additional authority, or scope expansion could change the result.
+- Do not add code or configuration comments unless the user explicitly asks for comments. This includes explanatory,
+  narrative, TODO, and documentation comments.
+- Use `flutter test`, not `dart test`, because models pull in Flutter types.
+- Run code generation after modifying models, providers, or database schema.
+- Do not manually edit generated files.
+- Preserve lifecycle ownership: desktop Core process convergence belongs to `lib/core/desktop/`; Android service intent
+  arbitration belongs to `ServiceState`. UI/provider code may request a transition but must not become a second source of
+  truth.
+- Keep start/stop/restart paths latest-intent-safe. Flutter-to-Android service commands are deliberately optimistic, while
+  native state serializes the actual work; desktop lifecycle results distinguish applied, coalesced, and superseded
+  requests.
+- Follow `analysis_options.yaml`, especially single quotes, trailing commas, `child:` last, no `print()`, const/final
+  preferences, and declared return types.
+- For CI parity, verify with `flutter pub get`, `flutter analyze --no-fatal-infos`, and
+  `flutter test --reporter expanded` when practical.
+
+## Repo Skills
+
+Use repo skills from `.agents/skills/` when a task matches their descriptions. Current skills cover localization,
+provider tests, UI work, and core/platform changes.
