+# v2rayNG agent guide
+
+## Scope and precedence
+
+This file applies to the entire repository. Read the applicable scoped guide before editing any
+listed path, including when the agent starts at the repository root:
+
+- Read `V2rayNG/app/src/main/java/com/v2ray/ang/service/AGENTS.md` for
+  `V2rayNG/app/src/main/java/com/v2ray/ang/service/`,
+  `V2rayNG/app/src/test/java/com/v2ray/ang/service/`, and these paths under
+  `V2rayNG/app/src/main/java/com/v2ray/ang/`: `core/CoreServiceManager.kt`,
+  `core/LauncherManager.kt`, `root/`, `contracts/ServiceControl.kt`,
+  `contracts/Tun2SocksControl.kt`, `handler/NotificationManager.kt`,
+  `helper/MessageHelper.kt`, and `helper/NotificationHelper.kt`.
+- Read `V2rayNG/app/src/main/java/com/v2ray/ang/ui/AGENTS.md` for
+  `V2rayNG/app/src/main/java/com/v2ray/ang/ui/` and
+  `V2rayNG/app/src/test/java/com/v2ray/ang/ui/`.
+
+Follow both guides in scoped paths. A scoped rule overrides a root rule only when they require
+incompatible actions; every other root rule remains active.
+
+## Requirement language
+
+- `must`, `must not`, `only`, and `never` are mandatory. Only the current user request or linked
+  acceptance criteria can state an exception; agent inference cannot.
+- `Task scope` is the named files and behavior plus dependency, test, or build edits that a
+  compiler or required validation proves necessary. Every other change is outside scope.
+- `Changed behavior` includes direct and downstream build-time or runtime effects through callers,
+  consumers, storage, IPC, and resources.
+- `Supported` versions, ABIs, distributions, and locales are exactly those declared by
+  `V2rayNG/app/build.gradle.kts` and `.github/workflows/build.yml` inputs.
+- A behavior is `verified` only when its named check passed on branch HEAD. Otherwise list the
+  exact unrun check and blocker, and do not call the behavior verified.
+
+## Existing code is not a compliance baseline
+
+- These guides define the target state; they do not claim that this checkout, an older commit, or
+  another worktree complies. Existing code shows current behavior and is not permission to repeat
+  a pattern.
+- A `touched declaration` is any function, property, class, composable, resource entry, manifest
+  element, or Gradle block containing an added or removed line. Inspect it and every caller or
+  consumer whose contract changes against all applicable rules before editing.
+- Every new declaration and changed behavior must comply. Inspect a helper or pattern before
+  reusing it. Tests prove only their assertions; names, green builds, and prior approval prove
+  nothing else.
+- Do not repair unrelated violations. Fix a violation left on a task-changed execution path in the
+  same branch; if that would change behavior outside scope, request approval first. Report any
+  remaining violation that blocks required validation.
+
+## Agent-guide synchronization and PR boundary
+
+- `AGENTS.md` files are the only rule source. `CLAUDE.md`, `GEMINI.md`, and
+  `.github/copilot-instructions.md` are routing shims and must only load or point to applicable
+  `AGENTS.md` files.
+- Feature, fix, and release branches use instruction files from fetched `upstream/master` as their
+  baseline. If `upstream` is absent, run
+  `git remote add upstream https://github.com/2dust/v2rayNG.git`; otherwise require
+  `git remote get-url upstream` to print exactly that URL. Successfully run
+  `git fetch upstream master` before comparison. An agent-instruction branch uses its HEAD and
+  working diff as the proposal.
+- At task start and after each upstream merge or rebase, synchronize canonical instructions into
+  the worktree without deleting local-only text. Compare them with:
+
+  ```sh
+  git diff upstream/master -- ':(glob)**/AGENTS.md' ':(glob)**/CLAUDE.md' ':(glob)**/GEMINI.md' .github/copilot-instructions.md
+  ```
+
+  After synchronization, every displayed difference must be inside a local-only block. If a branch
+  predates the files, keep copied versions untracked or unstaged; acquire tracked copies only by
+  merging or rebasing their upstream commit.
+- User-, machine-, worktree-, and temporary text is local-only. Put it in `AGENTS.md` between
+  visible lines `LOCAL INSTRUCTIONS - START` and `LOCAL INSTRUCTIONS - END`.
+  Unless the task targets agent instructions, treat every pre-existing instruction-file difference
+  as local-only.
+- Keep local-only text unstaged and uncommitted. Never use `git add .`, `git add -A`, or
+  `git commit -a` in that worktree. Stage task paths explicitly; never delete, restore, or overwrite
+  local instructions to clean the worktree.
+- Before each commit, push, or PR update outside agent-instruction scope, run both commands. Both
+  must print no paths; otherwise stop and remove the instruction change from the staged or branch
+  diff without altering its working copy.
+
+  ```sh
+  git diff --cached --name-only -- ':(glob)**/AGENTS.md' ':(glob)**/CLAUDE.md' ':(glob)**/GEMINI.md' .github/copilot-instructions.md
+  git diff --name-only upstream/master...HEAD -- ':(glob)**/AGENTS.md' ':(glob)**/CLAUDE.md' ':(glob)**/GEMINI.md' .github/copilot-instructions.md
+  ```
+
+- Commit instruction files only for a task explicitly limited to agent instructions. The branch
+  and PR may contain only `AGENTS.md` and necessary routing-shim changes; name agent instructions
+  in the PR title and state that exclusive scope in the body.
+
+## Project boundaries
+
+- The Android project is under `V2rayNG/` and uses Kotlin, Gradle Kotlin DSL, Compose, Material 3,
+  coroutines, and AndroidX lifecycle. Read dependency versions from
+  `V2rayNG/gradle/libs.versions.toml`, SDK levels from `V2rayNG/app/build.gradle.kts`, and CI tools
+  from `.github/workflows/build.yml`; never copy those numbers into a guide.
+- `AngApplication` initializes MMKV, app locales, WorkManager, defaults, and theme state. Persist
+  application data through `MmkvManager` or `SettingsManager`; do not create `SharedPreferences`
+  or another path for data they own.
+- `core/` owns native configuration and lifecycle, `handler/` data and application operations,
+  `service/` Android services, and `ui/` Compose activities, components, and ViewModels. Put new
+  code in its owner unless a scoped guide names a narrower owner.
+- Shared lifecycle and configuration code must retain VPN, proxy-only, and root-mode branches.
+  Change one mode only when task scope names it; gate the change and preserve the other modes.
+- `AndroidLibXrayLite` is native-core source. `V2rayNG/app/libs/libv2ray.aar` and the HEV libraries
+  are generated inputs; do not modify or commit them unless task scope upgrades a native dependency.
+  Such a PR must identify the source revision and verify every app-declared ABI.
+
+## Build and validation
+
+Before building a clean checkout, initialize submodules recursively and reproduce the HEV and AAR
+steps in `.github/workflows/build.yml`. The AAR revision must match the `AndroidLibXrayLite` gitlink
+from `git ls-tree HEAD AndroidLibXrayLite`. Take build-tool versions from that workflow and
+`V2rayNG/gradle/libs.versions.toml`.
+
+Run Gradle from `V2rayNG/`, using `gradlew.bat` in Windows PowerShell or `./gradlew` on POSIX. Use
+the Play Store debug variant unless task scope names another distribution.
+
+Apply every matching validation rule:
+
+- Documentation only: run `git diff --check`; no Gradle task is required.
+- Kotlin/Java production code: run the test class that asserts each changed behavior, then
+  `:app:testPlaystoreDebugUnitTest` and `:app:compilePlaystoreDebugKotlin`.
+- Resources, manifest, Gradle, dependencies, or native packaging: run
+  `:app:assemblePlaystoreDebug`.
+- F-Droid only: replace `Playstore` with `Fdroid`. Run both variants when shared code branches on a
+  flavor, `BuildConfig.DISTRIBUTION`, or a flavor-specific resource or dependency.
+- Android service lifecycle, framework callback, native interaction, permission, accessibility,
+  focus, or state restoration: also run an emulator or physical-device check.
+
+Add or update JUnit tests under `V2rayNG/app/src/test/java/` for changed deterministic logic. Report
+an unavailable required check under the exact label `Not run`, with its command or scenario and
+reason. A compile or assembled APK does not verify runtime behavior.
+
+There is no enforced Kotlin formatter. Preserve local indentation and import order. Do not change
+whitespace outside touched declarations or reorder imports except as the diff requires.
+
+## Repository-wide coding rules
+
+- Keep the diff inside task scope; exclude unrelated refactors, upgrades, generated files,
+  translation cleanup, renames, and formatting-only changes.
+- Use server GUIDs and group IDs for persistence, asynchronous work, and UI state. Never use a
+  list index, adapter position, or paging position as server or group identity.
+- Run disk, network, package-manager, native, bitmap, and CPU-intensive work off the main thread.
+  Own each asynchronous operation with a named lifecycle or ViewModel scope and cancel it when the
+  owner ends or newer work supersedes it.
+- Put all visible and accessibility text in Android resources. Update every locale in
+  `androidResources.localeFilters` for each changed key, preserving placeholders, plurals, and
+  formatting tags.
+- Never rename or delete a persisted, serialized, routing, import, or export field without a
+  backward-compatible migration and a regression test reading the preceding released format.
+  Multi-record writes must complete together or restore/remove partial writes on every failure.
+- Log recoverable failures through `LogUtil`, including operation, mode/component, non-secret
+  stable ID when available, and exception. Never log credentials, full proxy URLs, private keys,
+  or exported configurations.
+- Before adding a constant, helper, manager, repository, or state holder, search its owner. Extend
+  an owner that controls the same data or lifecycle. Create a new abstraction only for different
+  ownership or lifetime, and state that distinction in code or the PR.
+- A platform workaround needs a comment naming its Android/API or vendor boundary, prevented
+  failure, and exact removal condition.
+
+## Deprecated, experimental, and version-gated APIs
+
+- Introduce a deprecated API only for a supported-version fallback lacking the replacement, a
+  required deprecated callback/interface member, or a documented platform/vendor defect that
+  blocks acceptance criteria. The defect requires a test or linked upstream issue.
+- Isolate each permitted deprecated call in one compatibility function or adapter. Comment the
+  reason and an exact removal trigger. Use the stable API wherever available.
+- Scope `@Suppress("DEPRECATION")` or `@SuppressLint("<IssueId>")` to the containing expression or function.
+  Class scope is allowed only when every member implements the same required deprecated interface;
+  file, package, and module scope is forbidden. Never suppress permission, background-execution,
+  lifecycle, or security requirements.
+- Guard every API above `minSdk` by SDK or extension version in the same function, or use
+  `@RequiresApi` only when every entry point is guarded. Mark reusable guards
+  `@ChecksSdkIntAtLeast`. Lower versions must use an
+  existing API, return explicit unsupported status, or hide/disable the feature; never crash or
+  report false success.
+- Add or expand an experimental API only when no stable API meets named acceptance criteria, its
+  dependency is pinned in `libs.versions.toml`, a project-owned stable interface contains it and
+  excludes it from persisted data, IPC payloads, and public shared contracts, a regression test
+  covers it, and a comment names the opt-in marker and exact reevaluation condition.
+- Put `@OptIn` on the direct function/property, or on a class only when multiple members need it.
+  File and module opt-ins are forbidden. Existing experimental use outside scope does not permit a
+  new call site.
+- A preview/canary SDK or alpha dependency is allowed in production only when the request or linked
+  issue requires it. Keep a stable path for supported non-preview devices, gate by runtime API or
+  feature availability, and test both paths. After an API guard, opt-in, or lint suppression, run
+  `:app:lintPlaystoreDebug` and also `:app:lintFdroidDebug` when behavior differs by distribution.

+# Service code agent guide
+
+These rules apply to the service and service-adjacent paths listed in the repository-root
+`AGENTS.md`. Follow both guides; apply the precedence rule defined by the root guide.
+
+## Process and lifecycle invariants
+
+- The daemon process `:RunSoLibV2RayDaemon` is the only authority for whether the native
+  core is running. Do not use a UI-process singleton, cached Boolean, bound-service
+  assumption, or successful broadcast send as proof of daemon state.
+- Route every app-initiated VPN, proxy-only, and root start through `LauncherManager`.
+  Route service commands and their results through `MessageHelper`. Put lifecycle state
+  shared by two or more run modes in `CoreServiceManager` or `ServiceControl`. Do not
+  load or query the native core from the UI process to decide start, stop, or restart.
+- Keep Android-owned `VpnService` entry paths intact. `CoreVpnService` must accept a null
+  restart intent and the `VpnService.SERVICE_INTERFACE` action without requiring the
+  app-initiated `LauncherManager` path.
+- A start path is idempotent only when a second equivalent command leaves exactly one
+  native core, tunnel, foreground notification update loop, worker set, and root rule
+  set. Every edit to start dispatch or `onStartCommand` must preserve that result.
+- In each `onStartCommand`, enter foreground before reading configuration, opening a
+  file or socket, starting a coroutine that performs setup, invoking native code, or
+  executing a root command. `CoreVpnService`, `CoreProxyOnlyService`, and
+  `CoreRootService` must call `NotificationManager.ensureForeground()`;
+  `CoreTestService` and `SubscriptionUpdateService` must call
+  `NotificationHelper.startForeground()`.
+- On setup failure, cancel the setup job, release every resource created by that attempt,
+  remove partial root or VPN state, and stop the failed service instance. Do not return a
+  sticky restart mode unless `CoreServiceManager.isRunning()` is true, the service owns
+  every tunnel or root resource required by its run mode, and the Android restart path
+  reconstructs configuration, native core, notification, and mode-owned resources
+  without UI-process state.
+- Preserve these ownership boundaries: `CoreVpnService` owns the VPN interface and
+  socket protection; `CoreProxyOnlyService` owns local-proxy mode; `CoreRootService`
+  owns root routing. Code used by two or more of these services belongs in their common
+  lifecycle layer. Code used by one mode remains in that mode's service.
+
+## Cleanup, concurrency, networking, and IPC
+
+- Teardown must prevent new work before releasing dependencies. Mark the service as
+  stopping, reject or invalidate pending start/reload work, cancel and join setup jobs,
+  then release owned resources. Remove root routing before stopping its core listener.
+  Close each VPN descriptor and tun2socks resource once on setup failure, revoke, stop,
+  and destroy; make repeated teardown calls no-ops after the first close.
+- Every new coroutine launched by a service must be a child of a job or scope stored by
+  that service or the shared lifecycle owner. Cancel that owner during stop and
+  `onDestroy`. Do not use `GlobalScope`, an anonymous standalone `CoroutineScope`, or a
+  job whose parent outlives the service and later recreates routes, notifications,
+  files, or native state.
+- Do not add root commands, file I/O, network probes, or native calls directly to
+  `onCreate`, `onStartCommand`, `onRevoke`, or `onDestroy` on the main thread. Perform
+  the operation in the service-owned scope. If traffic-leak prevention requires the
+  callback to await completion, the call site must contain an explicit timeout and a
+  comment naming the leak-prevention ordering; an unbounded wait is prohibited.
+- A handover belongs to the `NetworkMonitor` instance that scheduled it.
+  `NetworkMonitor.unregister()` must cancel pending handover work and prevent its
+  callback from entering after `unregister()` returns. Immediately before reload, the
+  handover handler must verify that its monitor instance is still the instance owned by
+  `CoreServiceManager` and that the core is running. Stop and destroy must unregister
+  the monitor before clearing it or stopping the core.
+- Every app-internal broadcast intent must set its package to `AppConfig.ANG_PACKAGE`;
+  every app-internal service intent must use an explicit `ComponentName`. Do not add an
+  implicit broadcast or service intent. Each payload must implement the serialization
+  contract used by its receiver. When a caller must distinguish `handled by daemon`
+  from `daemon absent`, return an acknowledgement/result from the daemon. Broadcast
+  delivery, bind success, and command enqueue success are not acknowledgements.
+
+## Native resources, logging, and validation
+
+- `TProxyService` loads the JNI library `libhev-socks5-tunnel.so`; root mode executes
+  the separately packaged `libhevsockstun.so`. A native or packaging diff must inspect
+  the produced APK as a ZIP and confirm both HEV files and `libgojni.so` for every ABI
+  selected by `ABI_FILTERS` or, when that property is absent, every ABI in the app's
+  default `splits.abi` block.
+- A recoverable start, stop, reload, handover, or cleanup failure log must include the
+  run mode, lifecycle phase, stable non-secret profile/group identifier when one exists,
+  failed operation, and exception. Apply the root guide's secret-redaction rule.
+- Move deterministic lifecycle decisions into pure helpers and add a JVM regression test
+  for each changed decision. Apply this scenario mapping to service changes:
+    - Start dispatch, `onStartCommand`, or command deduplication: cold start and two
+      equivalent consecutive start commands.
+    - Foreground setup or setup-error handling: successful setup and failure after at
+      least one resource has been acquired.
+    - Stop or teardown: normal stop, repeated stop, and stop while setup is in flight.
+    - Restart or network handover: successful restart/handover and a stop racing the
+      pending restart/handover.
+    - Shared lifecycle code: run the mapped scenarios in VPN, proxy-only, and root modes.
+      Mode-owned code: run them in the owning mode.
+- Every service lifecycle scenario above requires an emulator or physical device; a JVM
+  test or assembled APK is not a substitute. Record each scenario that did not run under
+  `Not run`, with the device requirement or blocker. Do not claim the service change is
+  runtime-verified when any mapped scenario is unrun.

+# UI code agent guide
+
+These rules apply to the UI paths listed in the repository-root `AGENTS.md`. Follow both
+guides; apply the precedence rule defined by the root guide.
+
+## Compose architecture and state
+
+- Implement every new screen and component with the existing Compose and Material 3
+  stack. A new screen activity must extend `BaseComponentActivity` or
+  `HelperBaseComponentActivity` and place its screen, ViewModel, and action contract in
+  the package that owns its navigation entry. Do not add a fragment, ViewBinding layout,
+  XML screen layout, or RecyclerView adapter. Do not migrate existing legacy UI outside
+  task scope, and do not extend it or use it as the template for new UI.
+- Keep durable screen state and business work in a ViewModel/repository and expose it as
+  immutable observable state. Collect flows with `collectAsStateWithLifecycle()`.
+  Compose-local state is only for transient presentation state; use `rememberSaveable`
+  when that state must survive activity recreation.
+- Durable state includes loaded data, selection by domain ID, validation results,
+  progress, errors, and any value written to settings or a profile. Transient
+  presentation state is limited to visual expansion, animation, scroll/focus position,
+  and an uncommitted input value owned solely by the visible component. A composable
+  must not perform repository, MMKV, import/export, routing, or native-core work.
+- Send user operations through the owning feature's action/event contract and
+  ViewModel. Main-screen operations must use `MainAction` and `MainViewModel`.
+  Composables must not mutate a repository, `MmkvManager`, or `SettingsManager`
+  directly.
+- Use server GUIDs and group IDs for Compose keys, selection, saved state, and action
+  parameters. Do not persist or dispatch a visible index, adapter position, or paging
+  offset as identity. After filtering, sorting, subscription replacement, paging, or an
+  asynchronous result, resolve the item again by its domain ID.
+- Run blocking file, network, package-manager, and bitmap-decoding operations on
+  `Dispatchers.IO`. Run CPU-bound parsing, sorting, filtering, and transformation on
+  `Dispatchers.Default`. Launch both from the owning ViewModel or lifecycle scope.
+  Publish results through a private `MutableStateFlow` exposed as `StateFlow`; do not
+  read or write Compose snapshot state on either background dispatcher.
+
+## Interaction, accessibility, and layout
+
+- Give every icon with a click, long-click, toggle, or custom accessibility action a
+  localized accessible name that states its action. Set `contentDescription = null` on
+  every icon with no user action. Do not expose a raw URL,
+  package ID, GUID, or duplicated descendant label when a row-level semantic node
+  supplies the name.
+- A row with one activation behavior must expose one focusable semantic node, one
+  localized name, its current selected/on/off state, and one activation action. Merge or
+  clear descendant semantics so a label, icon, checkbox, and switch do not become
+  duplicate focus targets. Keep a descendant as a separate node only when it performs a
+  different user action; give that node its own name and role. TalkBack, touch, Enter,
+  Space, and D-pad center must invoke the same action for the same node.
+- Key each focusable list item by its domain ID. Reordering or recomposition must keep
+  focus on the node with that ID if it still exists. If a selection change removes or
+  replaces the focused node, move focus exactly once to the final active item after the
+  state update; do not announce or focus an intermediate item.
+- Use `stringResource` for text created inside a composable and localized
+  `Context.getString`/resources outside Compose. This rule covers visible labels,
+  semantic labels, state descriptions, validation messages, errors, dialogs, snackbars,
+  and toasts. Apply the root guide's locale and placeholder requirements to every key.
+- Every form containing a text-editing control must use a vertically scrollable
+  container. Inside a `Scaffold`, apply its `innerPadding`, call
+  `consumeWindowInsets(innerPadding)`, and
+  apply `imePadding()` to that container. Outside a `Scaffold`, apply `imePadding()` and
+  consume the navigation-bar inset exactly once. With the IME visible, the user must be
+  able to focus, read, edit, and activate both the first and last form controls without
+  dismissing the IME.
+- A shared component used by server screens must preserve edge-to-edge system-bar
+  insets, light and dark themes, dynamic color enabled and disabled, and both single-
+  and double-column layouts. A change to such a component requires rendering and
+  interaction checks in each of those configurations; dynamic-color checks require a
+  device or emulator that supports dynamic color.
+
+## Validation mapping
+
+Apply every row whose trigger matches the UI diff:
+
+- ViewModel state, action mapping, validation, filtering, parsing, or selection logic:
+  add or update a JVM test that asserts the initial state and every success, invalid-
+  input, empty-input, and failure branch added or modified by the diff.
+- `rememberSaveable`, `SavedStateHandle`, activity recreation, or restoration logic:
+  recreate the activity and verify the final state by domain ID, not list position.
+- Loading or data presentation: exercise every state represented by the owning state
+  model among empty, loading, error, and populated; do not invent states absent from
+  that model.
+- Click, toggle, selection, or navigation behavior: verify touch, keyboard focus and
+  activation, and D-pad focus and activation.
+- Semantics, focus, accessible text, row merging, or icon meaning: inspect the semantics
+  tree and run TalkBack on an emulator or device. Record the spoken label, state, focus
+  order, and activation result.
+- Form fields, scrolling, or insets: open the IME, traverse from the first control to the
+  last control, and activate the primary action with the IME still visible.
+- A setting, profile, routing rule, or other persisted value: perform the action, close
+  and reopen the screen, and verify the value through the owning ViewModel/repository.
+
+A screenshot verifies appearance only. It does not verify semantics, focus, activation,
+state ownership, persistence, or recreation. Record every mapped check that did not run
+under `Not run`; do not claim the corresponding behavior is verified.
