+# Agent Configuration Model
+
+Use the smallest durable surface that matches the job.
+
+## Surfaces
+
+- `AGENTS.md`: repository entry point. Keep it small and reserve it for always-on rules, routing, and high-priority expectations.
+- No `CLAUDE.md`: Claude Code v2.1.277+ loads `AGENTS.md` at startup only while no `CLAUDE.md`, `.claude/CLAUDE.md`, or `CLAUDE.local.md` sits in the working directory or above it, so adding one silently replaces `AGENTS.md` for Claude. Sessions that cannot load `AGENTS.md` directly (third-party providers, telemetry disabled) need an uncommitted `CLAUDE.local.md` containing `@AGENTS.md`. The one nested `CLAUDE.md`, in `plugins/rust_api/`, imports the root `AGENTS.md` for the same reason.
+- `.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 skills shared by Codex and Claude Code. Use these for repeatable workflows that should be discoverable by name and description; `.claude/skills/` holds one symlink per skill so Claude Code finds the same files.
+- `.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. None exist yet. 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.
+- Split a rule into the part that can be counted and the part that cannot, and enforce them differently. A rule resting entirely on judgment gets decided at the keyboard, at the moment the exception looks most justified; the comment policy is the worked example, where "is this comment useful" stays prose and review while "are these comments too frequent" became a measured gate. Find the countable half before writing more prose.
+- Restate the one-line form of a rule in every context that must obey it, and keep its explanation in one `.agents/*.md` file that the others link to. Prefer a runnable check to either: a gate an agent trips before reporting done outperforms a paragraph asking it to have been careful.
+- State a gate's real force. Enforcement differs per tool, and a rule that claims uniform coverage it does not have is worse than one that names the gap.
+- 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.

+# 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
+```
+
+The desktop Go core and the Rust helper build automatically: Flutter runs
+`plugins/setup/hook/build.dart` on every `flutter build` and `flutter test`,
+and the hook drives `CoreBuilder` from the `setup_hooks` package in
+`plugins/setup/setup_hooks/`. Artifacts land in `libclash/`. Android's Core is
+the AAR the `:core` Gradle module builds with `gomobile bind` before anything
+compiles against it; that needs `go` on `PATH` and nothing else, since the
+gomobile tools come from `core/go.mod` and the NDK from AGP. The hook reruns only when Go, Rust, or
+`setup_hooks` inputs change; the fingerprint cache lives in
+`.dart_tool/setup_build_cache/`. To force a rebuild, delete that directory:
+
+```bash
+rm -rf .dart_tool/setup_build_cache
+```
+
+Flutter hides the hook's output on success, so to see why the Core was or was
+not rebuilt read `.dart_tool/setup_build_cache/hook.log`; each invocation starts
+with a `===` line carrying its timestamp and target.
+
+The hook runs for `flutter test` and for `dart run` of any root-package script
+too, so a pure Dart test run needs the Go toolchain, and on Linux and Windows
+also `cargo` and `rustc` — the Helper fingerprint shells out to both even on a
+cache hit. The hook protocol carries no build mode and no caller, so the only
+switch is the user-define in the root `pubspec.yaml`:
+
+```yaml
+hooks:
+  user_defines:
+    setup:
+      build_assets: true   # false turns the Go core and Helper hook into a no-op
+    rust_api:
+      build_assets: true   # false does the same for the Rust library
+```
+
+CI flips `setup` to `false` with `yq` in its throwaway checkout before
+`dart run tool/changelog.dart` and `dart run tool/test.dart`; no test loads the Go core. `rust_api`
+stays on there because the editor tests in `test/plugins/code_forge/` and the socket
+test in `test/core/desktop/ipc_native_test.dart` load the Rust library the hook
+builds; the release-notes job, which runs no tests, flips both.
+Never commit `false`: a build with it set stages whatever `libclash/` already
+holds and bundles no Rust library, which is why `setup.dart` refuses to package
+while it is set. Locally, `false` is worth setting for a Dart-only test loop,
+but the hook cache keys on the user-define, so the first build afterwards runs
+the hooks again. The editor and IPC socket tests still need the Rust library: keep `rust_api`
+on, or point `FRB_DART_LOAD_EXTERNAL_LIBRARY_NATIVE_LIB_DIR` at a directory that
+holds a `rust_api` library built from the same sources.
+
+## 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.
+
+A development build takes over the host exactly like a release: it creates the TUN device, sets the system proxy, on
+macOS rewrites the system DNS, registers itself as the login item, and on Windows and Linux starts its Core through the
+shared privileged Helper, which stops the Core an installed FlClash is running. Only the data directory is kept apart,
+and only for some builds: a macOS debug build is `com.follow.clash.debug` and an Android debug build `com.follow.clash.dev`,
+while profile and release builds, and every build on Windows and Linux, share the directory and preferences of the
+installed app. Safe mode keeps all of the host changes off and never opens the Core's listeners or external
+controller, so it does not compete with the installed app for the mixed, DNS, RESTful API and other loopback ports:
+
+```bash
+flutter run --dart-define-from-file=env.json --dart-define=SAFE_MODE=true
+```
+
+`.run/main_safe_mode.run.xml` is the same launch for IntelliJ, and `Flutter App (Safe Mode)` in `.zed/debug.json` (debugger) or `flutter run (Safe Mode)` in `.zed/tasks.json`
+(plain run) for Zed. The build is bannered `SAFE MODE`, the tray shows the
+`status_4` bug icon with a menu of only show and exit and no traffic title, and the settings keep their values, so
+nothing has to be flipped back before a normal run. See the safe mode section of `architecture.md` for the owners that consult the flag.
+
+## 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`.
+
+The Dart-Rust bindings in `plugins/rust_api` are generated by `flutter_rust_bridge_codegen` from
+`plugins/rust_api/flutter_rust_bridge.yaml`; rerun it from that directory after changing anything under
+`rust/src/api/`:
+
+```bash
+cd plugins/rust_api && flutter_rust_bridge_codegen generate
+```
+
+Generated output paths, configured in `build.yaml`:
+
+- `lib/models/generated/*.g.dart`, `*.freezed.dart`.
+- `lib/providers/generated/*.g.dart`.
+- `lib/database/generated/*.g.dart`.
+
+Tray and Windows app icons are generated, not hand-edited. `assets_source/images/icon/*.svg` is
+the source of truth; the script needs `rsvg-convert` (librsvg) on `PATH`:
+
+```bash
+dart run tool/generate_status_icons.dart
+```
+
+It writes the tray PNGs with Flutter `2.0x/`–`4.0x/` resolution variants to `assets/images/tray/unix/`,
+multi-size tray `.ico` files to `assets/images/tray/windows/`, and `windows/runner/resources/app_icon.ico`
+from `assets/images/icon.png`. macOS draws its menu bar icon as a template, so it skips the ringed color
+icons, whose logo shrinks to a small glyph once only alpha shows: `status_1` renders the bare logo from
+`assets_source/images/icon/glyph.svg` and `status_4` reuses `status_4.svg`, both recolored to black into
+`assets/images/tray/macos/`; the sources keep their colors. `glyph.svg` is also the geometry of the Android notification drawables
+`android/service/src/main/res/drawable/ic.xml` and `ic_service.xml`; change them together. `pubspec.yaml` declares the three tray directories with `platforms:` so each
+build only bundles the format its tray loads; a new status icon needs a source SVG and an entry in the
+script's `statusIconNames`, nothing in `pubspec.yaml`.
+
+## 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
+```
+
+For the whole suite, or a directory of more than a few files, use `tool/test.dart`, which is also what CI runs:
+
+```bash
+dart run tool/test.dart                                  # all of test/
+dart run tool/test.dart test/widgets test/views          # some paths
+dart run tool/test.dart -- --reporter expanded --coverage
+```
+
+Plain `flutter test` compiles each file into its own program and starts an engine for it, one file after another, and
+that dominates a full run: 329 files took 128 s on a 12-core Mac with at most four running at once. `tool/test.dart`
+imports the files into 32 generated entrypoints under `.dart_tool/test_bundles/` and runs those with one worker per
+core: about 60 s for the same run, and 67 s instead of 180–213 s with `--coverage`. Files in one entrypoint share an
+isolate, so a test can see state a file before it left behind; the script runs every file that failed there again on
+its own, lets that run decide, and names the files that only failed together. See the Shared Test Isolate section of
+`rules.md` before fixing one.
+
+`plugins/setup/setup_hooks/` is a pure Dart package and is tested with `dart test` from its own directory, which is
+also what CI runs; `tool/check_plugins.sh` does not descend into it. It must stay out of `flutter test`, because a test
+run of `plugins/setup` would execute the build hook itself.
+
+Native plugin code under `plugins/*/{linux,macos,windows}` is compiled by the CI `desktop` job, which runs
+`flutter build <platform> --debug` on every branch push, and by the release matrix on a tag; `tool/check_plugins.sh`
+only analyzes and tests the Dart side.
+
+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, or run `bash tool/check_plugins.sh` to analyze and test every plugin package the way CI does. 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. `ipc_native_test.dart` runs the transport over a real socket through
+  the Rust `IpcServer`; the server's own behavior is covered by `cargo test` in `plugins/rust_api/rust`.
+- `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, the Android files included:
+
+```bash
+cd core
+CGO_ENABLED=0 go test .
+CGO_ENABLED=0 go vet . ./cmd/...
+GOOS=android GOARCH=arm64 CGO_ENABLED=0 go vet -tags=with_gvisor . ./mobile ./tun ./platform
+```
+
+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, with the JDK 17 that CI installs. On macOS the Homebrew `openjdk@17` keg is not
+registered with `java_home`, so export it by prefix:
+
+```bash
+cd android
+export JAVA_HOME="$(brew --prefix openjdk@17)/libexec/openjdk.jdk/Contents/Home"   # elsewhere: any JDK 17
+./gradlew :core:compileDebugKotlin -Ptarget-platform=android-arm64   # builds the gomobile AAR for one ABI
+./gradlew :service:compileDebugKotlin
+./gradlew :app:compileDebugKotlin
+```
+
+Always-on VPN entry, system VPN revoke, actual permission UI, and rapid device start/stop still require Android device or
+emulator validation; Kotlin compilation cannot prove those system callbacks.
+
+## Changelog And Release
+
+The changelog is derived from Conventional Commits by `tool/changelog.dart` and written to two committed files:
+`CHANGELOG.md` for readers and `changelog.json` for the renderers. See `.agents/rules.md` for the `Changelog:` trailers
+that decide the wording.
+
+The app ships no changelog of its own. `render release` appends the released version as JSON inside an HTML comment
+(`<!-- flclash:changelog:json … -->`), so the release body GitHub already returns to `checkForUpdate` carries the
+notes shown in the update dialog. `parseReleaseChangelog` reads that block and falls back to the English
+bullets when a release predates it.
+
+```bash
+dart run tool/changelog.dart verify                  # what CI checks
+dart run tool/changelog.dart release --version 0.8.96
+dart run tool/changelog.dart build --unreleased      # changelog.json only, includes untagged work
+dart run tool/changelog.dart render release --out release.md
+dart run tool/changelog.dart render telegram --out telegram.md
+```
+
+Releasing a stable version, in order:
+
+```bash
+tool/bump_version.sh all
+dart run tool/changelog.dart release --version 0.8.96
+git commit -am "chore(release): v0.8.96"
+git tag v0.8.96
+git push origin main && git push origin v0.8.96
+```
+
+Push the tag by name. Every release tag here is lightweight, and `--follow-tags` carries annotated tags only: it skips a
+lightweight one silently, so the branch lands, the tag does not, and the release workflow never fires.
+
+`tool/release.sh` drives both paths so the ordering below cannot be got wrong by hand. It resolves the version (bumping
+the patch when pubspec still names an already tagged one), prints the notes the tag would ship, and only pushes with
+`--push`:
+
+```bash
+tool/release.sh pre --dry-run     # plan and notes, changes nothing
+tool/release.sh pre --push        # bump, tag vX.Y.Z-pre.N, push
+tool/release.sh stable --push     # changelog, chore(release) commit, tag, push
+```
+
+The release commit comes before the tag on purpose: the generated wording is reviewable in the diff before it ships, and
+the tag is what `render release` reads. CI never writes back to the repository; it only runs `verify`. Wording in
+`changelog.json` may be edited by hand as long as no derivable entry disappears and every entry still points at a commit
+inside that version's range.
+
+Entries at or below `v0.8.96` are frozen: they predate the pipeline, live under the `<!-- changelog:frozen -->` marker
+in `CHANGELOG.md`, and are never regenerated.
+
+`verify` compares a version only when its tag is reachable from `HEAD`, because that is the same scope the builder walks
+(`git tag --merged`). A branch cut before the newest release cannot derive that version at all, so `verify` names it as
+skipped and moves on instead of reporting drift that does not exist. Checking mere tag existence is what made every such
+branch fail on an unrelated release.
+
+Prerelease tags (`v0.8.96-pre.N`) skip the release commit, and CI renders their notes with `build --unreleased` for the
+Telegram post. They publish no GitHub release, so the update dialog never sees them. `build --unreleased` reads the
+version from `pubspec.yaml` rather than the tag, so the patch has to be bumped before the first `-pre.N` of a cycle:
+while `v<pubspec version>` is still tagged it refuses to collect anything and the release job fails.
+
+### Website
+
+`site/` is the GitHub Pages site: a static page that renders `CHANGELOG.md` and the download links in the browser, and
+works as is for local previews. `tool/build_site.sh [dir]` assembles it with the preview images, the app icon,
+`CHANGELOG.md` read at the latest release tag, and a `release.json` of asset names, sizes and digests fetched through
+`gh`. Without `gh` access the page falls back to the newest version in `CHANGELOG.md` and lists the files without sizes.
+It then runs `tool/render_site.mjs` (Node), which writes the English page and a `zh/` copy for search engines: page
+text, the first changelog releases, canonical and `hreflang` links, JSON-LD and `sitemap.xml`, all from the strings,
+changelog parser and release markup in `site/assets/shared.js`, plus the GitHub star count from `release.json` so the
+nav does not grow when the page loads. `SITE_URL` overrides the published URL these point at.
+On the built site each URL keeps its language: the language button links to the other page and carries the section in
+view, the chosen platform and the changelog search. Only the English root sends readers who chose or prefer Chinese on
+to `zh/`, unless its URL carries `?lang=en`: the button on `zh/` links there with it, so getting back to English never
+depends on browser storage. A project site cannot serve the `robots.txt` that would announce the sitemap, so submit
+`sitemap.xml` in Google Search Console and Bing Webmaster Tools once.
+
+```bash
+tool/build_site.sh && python3 -m http.server -d build/site
+```
+
+The page's look is deliberate: low-saturation flat colour, no blur, glow, glass or soft shadow, and motion that follows
+the logo's 30° lattice. `site/assets/field.js` draws the hero's capsules on that lattice with the glyph's own
+proportions, and the slanted wipes, the dot-to-bar marks and the theme transition reuse the same angle. Text that sits
+inside the hero has to be listed in `wireField` in `app.js`, or the capsules run behind it.
+
+`.github/workflows/pages.yaml` deploys it after every successful stable tag build and on pushes to `main` that touch the
+site, in the public repository only; its Pages source has to be set to GitHub Actions once. The file names come from the
+release matrix in `build.yaml`, so a renamed artifact needs the same change in `buildsFor` in `site/assets/app.js`.
+
+## Verify
+
+In the public repository every branch push runs the `dart` job; in the private
+`origin` every check job runs only when started by hand (`workflow_dispatch`).
+The `dart` job performs these root-package checks in order:
+
+```bash
+bash tool/hooks/test.sh
+flutter pub get
+dart format --output=none --set-exit-if-changed lib test tool plugins setup.dart
+flutter analyze --no-fatal-infos
+dart run tool/changelog.dart verify   # main and tags only
+flutter test --reporter expanded --coverage
+dart run tool/check_coverage.dart coverage/lcov.info 75
+```
+
+`tool/hooks/` holds the scripts the git hooks run, and `tool/hooks/test.sh` runs every `*_test.sh` beside them, so a
+new hook script needs only its test file next to it, not a workflow step.
+
+Run `flutter analyze` before committing; CI fails on anything it reports.
+
+Release builds run only for `v*` tag pushes; pull requests trigger nothing.
+Root analysis excludes `plugins/**`, and root tests do not discover nested
+plugin packages, so parallel jobs validate the rest from their own package
+directories: `plugins` (local Flutter packages and the setup build tool), `go`
+(the Core wrapper, plus a vet of the Android files), `android` (JVM unit tests
+for `:common`, `:service` and `:app`, with the Flutter compile tasks excluded
+and the gomobile AAR built for one ABI), `rust` (both crates), and a
+Windows runner for the helper's `windows-service` feature. On branch pushes a
+`desktop` job also compiles a debug build per desktop platform; a tag skips it,
+since its release matrix compiles the same native code. Release builds run only
+in the public repository and start alongside the checks; `upload` publishes
+only once every build and every check job passes.
+
+`bash tool/check_plugins.sh` is that plugin gate, and CI runs the same script.
+It discovers every `plugins/*/pubspec.yaml`, analyzes each package, and runs
+`flutter test` wherever `test/*_test.dart` exists. Adding a plugin package needs
+no workflow edit; enumerating packages by hand in the workflow is what
+previously left `plugins/tray` unanalyzed and untested.
+
+### CI Caches
+
+A run restores only cache entries saved on its own branch or tag, or on the default branch (`main`), and the
+repository holds 10 GB before evicting the least recently used entries. Every release is a new tag that no later run
+reads from, so `BRANCH_CACHE` turns caching off in tag runs: one release used to write about 9 GB of such entries and
+evict everything `dev` had saved. Release builds therefore start cold; branch runs, chiefly `dev`, keep the caches.
+
+- setup-go keys its entry on the `cache-dependency-path` files alone and saves only on a miss, so jobs listing the
+  same files share one entry holding the build cache of whichever finished first. `desktop` and `android` each add
+  the file that drives their Core build to get an entry of their own.
+- setup-gradle writes only on the default branch unless told otherwise, so `android` lets `dev` write as well. Its
+  entries are keyed by job, which is one more reason the release build gains nothing from caching.
+
+## Worktree Tooling
+
+```bash
+bash tool/worktrees.sh list       # every worktree with owner tool and dirty/clean state
+bash tool/worktrees.sh prune      # remove clean worktrees; add --force to drop dirty ones too

+# Flutter Upgrade Checklist
+
+Read this before changing `FLUTTER_VERSION` in `.github/workflows/build.yaml` or `.fvmrc`. Each entry is a
+workaround tied to a Flutter bug: what it does, where it lives, and what has to be true before it can go. Remove an
+entry together with its workaround; add one whenever a new workaround is pinned to the SDK.
+
+## Stable cadence
+
+Flutter ships a stable release about once a quarter, three minor versions apart (3.41 in February, 3.44 in May, 3.47
+in August 2026). The two minors in between (3.48, 3.49) are beta only, so a fix that lands on `main` reaches stable
+in the next multiple, 3.50, expected around mid-November 2026. Hotfix releases (3.47.x) carry only cherry-picks
+listed in the SDK's `CHANGELOG.md`.
+
+## Impeller disabled on Intel macOS release builds
+
+- **Bug:** [flutter/flutter#191538](https://github.com/flutter/flutter/issues/191538). From 3.47, when Impeller
+  became the default desktop renderer, Intel (x86_64) Macs flicker across the whole window while scrolling or
+  animating, and text can render garbled. Apple Silicon is not affected.
+- **Fix upstream:** landed on `main` before 2026-08-25 and verified on `3.48.0-1.0.pre-404`; it is not in any
+  3.47.x hotfix (checked through 3.47.6).
+- **Workaround:** the release job for `macos-15-intel` (`arch: amd64`) runs
+  `plutil -replace FLTEnableImpeller -bool NO macos/Runner/Info.plist` before `dart setup.dart`, so only the Intel
+  DMG falls back to Skia. The checked-in `Info.plist` does not set the key, so local builds and the arm64 DMG keep
+  Impeller. The macOS embedder reads the key at launch in `FlutterDartProject.mm` (`enableImpeller`), release
+  builds included.
+- **Side effect:** Skia on Intel renders blur, shadows and text slightly differently; judge Intel-only visual reports
+  against Skia, not Impeller.
+- **Remove when:** `FLUTTER_VERSION` moves to a stable that contains the fix (3.50 or later, or a 3.47.x whose
+  changelog lists #191538). Before dropping the step, build the Intel DMG without it and scroll the proxies and
+  dashboard pages on an Intel Mac with its integrated GPU driving the built-in display; an external display can
+  switch to the discrete GPU and hide the flicker.
+
+## Wrong-size back buffer on macOS
+
+- **Bug:** [flutter/flutter#185394](https://github.com/flutter/flutter/issues/185394). `removeSurfaceForSize:` in
+  the macOS engine's `FlutterSurfaceManager.mm` hands out the youngest idle cached surface without checking its size.
+  When the window flips between sizes while the window server still holds the previous surface, which dragging a
+  window edge back and forth does, a request for one size gets a surface of another. Impeller's Metal texture then
+  disagrees with its descriptor, the render target drops it, and `Canvas::SetupRenderPass` dereferences a null
+  texture on the raster thread. Debug builds log `The texture and its descriptor disagree about its size` and
+  `Store action needs resolve but no valid resolve texture specified` first; release builds just crash.
+- **Fix upstream:** [flutter/flutter#192522](https://github.com/flutter/flutter/pull/192522), still open; 3.47.6
+  ships the same `FlutterSurfaceManager.mm` as 3.47.4.
+- **Workaround:** `BackBufferCacheGuard` in the `window` plugin's
+  `macos/window/Sources/window/BackBufferCacheGuard.swift`, installed from `WindowPlugin.register`, replaces
+  `-[FlutterBackBufferCache removeSurfaceForSize:]` at runtime and answers nil when the cached surface is not the
+  requested size, so the engine allocates a new one. It does nothing if the engine no longer has that class or
+  selector.
+- **Remove when:** `FLUTTER_VERSION` moves to a stable that contains #192522 (check the SDK `CHANGELOG.md` for a
+  3.47.x cherry-pick). Before dropping it, run a debug build without the guard on that SDK and drag a window edge
+  back and forth for a minute; neither validation line may appear.
+
+## Windows view visibility forwarded by the runner
+
+- **Bug:** the Windows embedder's `WindowsLifecycleManager` counts the Flutter view as a window of its own and keeps
+  it visible until the view is sized to zero. Hiding the top-level window never resizes the view, and the `window`
+  plugin keeps it sized while minimized, so the app was never told `hidden`: animations kept rendering in the tray
+  and `appVisibleProvider` stayed true.
+- **Workaround:** `WindowPluginForwardVisibility` in the `window` plugin's
+  `windows/include/window/window_plugin_runner.h` hands the top-level window's `WM_SHOWWINDOW` and `WM_SIZE` to
+  `ProcessExternalWindowMessage` for the view's HWND, so the view shows and hides with its window.
+  `FlutterWindow::MessageHandler` in `windows/runner/flutter_window.cpp` calls it before `HandleTopLevelWindowProc`;
+  the Flutter runner template has no such call, so keep it when regenerating the runner.
+- **Remove when:** the engine hides the view together with its top-level window. Check with the proxy running and
+  the window focused: hiding it to the tray and minimizing it must each log `AppLifecycleState.hidden`.
+
+## macOS activation resumes a hidden window
+
+- **Bug:** `handleWillBecomeActive` in the macOS engine's `FlutterEngine.mm` resumes when any window in
+  `NSApp.windows` is visible, and the tray's `NSStatusBarWindow` always is. Activating the app while its window was
+  minimized or hidden, such as Cmd-Tab back to a minimized window, reported `resumed`, and the next deactivation
+  `inactive`, so frames ran until the window was shown again.
+- **Workaround:** the `window` plugin observes will-become-active and will-resign-active and, once the engine has
+  answered, sends `AppLifecycleState.hidden` on `flutter/lifecycle` while its window is not visible
+  (`applicationActivityChanged` in `WindowPlugin.swift`). A window brought back without another activation change
+  would then wait on an occlusion notification macOS does not always post, keeping its last frame, so `show` and a
+  deminiaturize hand the state back (`windowBecameVisible`).
+- **Remove when:** the engine ignores status item windows on activation. Check without the workaround: minimize the
+  window, switch to another app, then Cmd-Tab back without restoring it; the log must stay at
+  `AppLifecycleState.hidden`.
+
+## Linux minimize on Wayland reads as inactive
+
+- **Bug:** the Linux engine reports `hidden` for `GDK_WINDOW_STATE_ICONIFIED`, but xdg-shell has no minimized state,
+  so GTK 3 never sets it on Wayland. A minimized window reported only its focus loss, as `inactive`, and kept
+  rendering at the display rate (GNOME 46).
+- **Workaround:** the `window` plugin's Linux `minimize` records the time, and a focus loss within 500 ms of it sends
+  `AppLifecycleState.hidden`. Its `window-state-event` handler is connected after the engine's, so that message
+  follows the engine's `inactive`; the compositor focuses the window when it restores it, which the engine reports as
+  `resumed`. A minimize the compositor starts itself (Super+H, the dock) is not covered.
+- **Remove when:** the Linux engine reports minimized windows on Wayland, which needs GTK 4 or xdg-shell's
+  `suspended` state. Check in a GNOME Wayland session without the workaround: minimizing from the caption button
+  must log `AppLifecycleState.hidden`.
+
+## Liquid glass saves around the transform of a blurring layer
+
+- **Bug:** not filed upstream. On 3.47 Impeller scales a `saveLayer`'s image filter by a transform set inside the
+  layer that is still in effect when the layer is restored. A host's capture shrinks each pane's slot inside the
+  layer that blurs it, so its blur vanished at a quarter scale and spread half again as far at 1.5.
+- **Workaround:** `_LiquidGlassHostLayer._snapshot` sets each slot's transform inside a `save` of its own, and each
+  band's offset, restored before the layer is.
+- **Remove when:** without that `save`, the frosted-pane case of `test/widgets/liquid_glass_host_test.dart` passes
+  under `flutter test --enable-impeller`.

+# Project Context
+
+FlClash is a multi-platform proxy client based on ClashMeta (mihomo), built with Flutter. It supports Android, Windows, macOS, and Linux, using Material You from `material_ui` as the base with Apple's Human Interface interaction conventions layered on top.
+
+## Version Notes
+
+- Flutter stays on the 3.47.x line. Release CI pins 3.47.6 and is the source
+  of truth for release builds; `.fvmrc` and local SDKs may sit on another 3.47
+  patch. The editor in `plugins/code_forge` came from `code_forge` 10.14.0, which
+  needs Dart 3.13.2, so the CI pin cannot go below Flutter 3.47.2.
+- Before moving the pin, walk `flutter-upgrade.md`: it lists the workarounds tied to
+  the current SDK, such as Impeller disabled on the Intel macOS release build.
+- The Dart SDK lower bound in `pubspec.yaml` sets the package language
+  version. `flutter analyze` excludes `lib/**/generated/**`, so a raise is
+  proven by `flutter test`, which parses the generated code, not by analyze.
+
+## Forked Dependencies
+
+One `pubspec.yaml` dependency is pinned to a fork by commit SHA. The fork lives
+under `chen08209`, the same account that owns this repository, so it is
+maintained in-house rather than tracked from a third party: advancing a pin is a
+local decision, and there is no external maintainer to wait on for the patch
+itself. What the fork still waits on is the *upstream* fix that would let the pin
+be dropped entirely, recorded below.
+
+Each entry records what the fork changes and what has to be true before it can go
+back to the published package, so a future upgrade does not have to rediscover it.
+Re-verify a fork by diffing its pub cache checkout against the published version
+of the same number:
+
+```bash
+diff -ru ~/.pub-cache/hosted/pub.dev/<name>-<version> ~/.pub-cache/git/<name>-<sha>
+```
+
+The `window_manager` fork (`chen08209/window_manager`, tag `v0.5.1-flclash.3`)
+was replaced by the in-repo `plugins/window` package; the behaviors it carried
+(work-area maximize with a hidden title bar on Windows, geometry restore on
+re-map on Linux, corner preference, terminate and activate events) live there
+now, see the window plugin section of `architecture.md`.
+
+`launch_at_startup` — `chen08209/launch_at_startup`, version 0.5.1.
+
+- Migrates `win32_registry` from `^2.0.0` to `^3.0.3`, which is a breaking rename
+  across the whole Windows implementation (`Registry.openPath` → `CURRENT_USER.open`,
+  `createValue` → `setValue`, `getStringValue` → `getString`).
+- This one is not optional while it lasts: FlClash depends on `win32_registry: ^3.0.3`
+  directly, and upstream's `^2.0.0` constraint cannot co-resolve with it.
+- Drop the fork when upstream publishes a release that accepts `win32_registry` 3.x.
+
+The `yaml_writer` fork (`chen08209/yaml_writer`) was replaced by
+`lib/common/yaml_writer.dart`. Its key quoting let keys such as `!a`, `'a` or
+`0x1F` reach the Core's yaml.v3 as a parse error or a non-string; a merge key
+`<<` stays plain on purpose, because `package:yaml` keeps it as an ordinary key
+and the Core applies the merge.
+
+The `code_forge` fork (`chen08209/code_forge`) is frozen: its Dart code now lives
+in the in-repo `plugins/code_forge` package and its Rust code in the `editor/`
+module of `plugins/rust_api`, both trimmed to what FlClash uses.
+`plugins/code_forge/README.md` records what was kept and what was removed;
+upstream's MIT notice stays in `plugins/code_forge/LICENSE`.
+
+## Dependency Ceilings
+
+`flutter pub outdated` lists only upstream-held entries, so treat them as
+resolved-until-the-ceiling-moves rather than as debt:
+
+- `intl` is intentionally unbounded (`any`) and `material_color_utilities` is
+  resolved by the Flutter SDK; neither is a bound this repository sets.
+
+The `riverpod` set, `build_runner`, `drift_dev` and `intl_utils` resolve to their
+latest releases. Two are held back:
+
+- `freezed` 4.0.2 needs `analyzer` 14, while `intl_utils` 2.8.16 still requires
+  `analyzer` ^13. It moves once `intl_utils` accepts analyzer 14.
+- `test` 1.32.0 needs `test_api` 0.7.14, and `flutter_test` on Flutter 3.47 pins
+  0.7.12. It moves with the SDK.
+
+When an upgrade fails version solving, record the blocker here with
+what has to change upstream before the pin can move, so the next
+`flutter pub outdated` run does not rediscover it.
+
+`_initDynamicColor` in `lib/bootstrap.dart` reads the `dynamic_color` method
+channel directly and decodes the palette list into a `TonalPalette`, instead of
+going through `DynamicColorPlugin.getCorePalette()` and its deprecated
+`CorePalette` return type. Everything downstream sees `DynamicColorSeeds`, so a
+non-deprecated plugin accessor changes only that one function.
+

+# 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
+
+The lint set lives in `lint_options.yaml` at the repo root. The root `analysis_options.yaml` and every local plugin under
+`plugins/*` include it, so application and plugin code are held to the same rules. Add or change a rule there, not in an
+individual `analysis_options.yaml`; those files carry only their own `analyzer.exclude` entries.
+
+`lint_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`.
+- `only_throw_errors: true`: throw an `Exception` or `Error`, never a bare `String`.
+
+Failures whose whole content is a message meant for the user throw
+`MessageException` from `lib/common/exception.dart`. Its `toString()` is the bare
+message, which is what `globalState.safeRun` surfaces in the dialog, so the
+user-facing text is unchanged from the older `throw someMessage` idiom while the
+throw stays catchable as an `Exception` and carries a stack trace. Assert on it
+with `isA<MessageException>().having((e) => e.message, 'message', ...)`, not on a
+raw string.
+
+### Corner Radius
+
+Rounded corners are superellipses (continuous corners) everywhere, never circular arcs; when a component offers
+both, pick the superellipse. `test/lint/superellipse_corners_test.dart` fails on the circular APIs below in `lib/`. Use
+the superellipse API at each layer:
+
+- Shapes: `RoundedSuperellipseBorder` instead of `RoundedRectangleBorder`.
+- Clips: `ClipRSuperellipse` instead of `ClipRRect`.
+- Container decorations: `ShapeDecoration(shape: RoundedSuperellipseBorder(...))` instead of
+  `BoxDecoration(borderRadius: ...)`; borders move to the shape's `side`, and a `Container` with
+  `clipBehavior` still clips to the shape path.
+- Canvas: `canvas.drawRSuperellipse(RSuperellipse.fromRectAndRadius(...))` instead of `drawRRect`.
+- Ink: `InkWell.customBorder` with an `AppShape` instead of `InkWell.borderRadius`.
+
+Passing `BorderRadius.circular(x)` as the `borderRadius` argument of these APIs is expected — it only
+carries the corner magnitude; the rendered geometry stays a superellipse.
+
+Pills are no exception. `StadiumBorder` joins its round caps to the straight sides with a curvature jump, while
+`AppShape.full`, a superellipse at full radius, blends them, and on a square it renders the exact circle, so it serves
+circles too. Material 3 defaults every button, icon button, segmented button, and search bar to `StadiumBorder`;
+`ThemeData.withAppShapes` replaces that for the button themes, and a local `FilledButtonTheme` or `IconButtonTheme`
+replaces the app's, so merge the ambient `XButtonTheme.of(context).style` into it, as `CommonMinFilledButtonTheme`
+does. `CircleBorder` and `BoxShape.circle` are fine for something that is always square.
+
+APIs that accept only a `Radius`, such as `ScrollbarThemeData.radius`, keep circular corners; supply the superellipse
+with an enclosing clip or shape where it shows. Framework widgets that paint their own circular corners with no shape or
+decoration to override, such as the `Switch` track, are left as Material draws them. Tooltips take theirs from
+`withAppShapes`, which sets `tooltipTheme.decoration`.
+
+### Typography
+
+Text sizes follow Apple's iOS Dynamic Type scale at its default size, on every platform. `AppTextStyle` in
+`lib/ui/typography.dart` holds its eleven styles, `largeTitle` to `caption2`, with Apple's leading and weights, plus two
+steps the scale lacks: `display` for a dashboard figure and `pageTitle` for an app bar. Take one with
+`AppTextStyle.body.of(context)`, pass `emphasized: true` for the scale's emphasized weight (bold for the titles,
+semibold for the rest), and change color or family with `copyWith`; a weight is either regular or emphasized. Text
+sized to the shape it marks, such as a letter scaled to its icon, comes from `AppTextStyle.custom`. The dashboard's
+roles (`DashboardText` in `lib/views/dashboard/style.dart`) are built on the same types. `ThemeData.withAppTypography`
+maps Material's `TextTheme` slots onto the scale so Material components follow it; app code never reads those slots.
+
+App bar titles sit at the leading edge in `pageTitle` on a root page and on any desktop page, at the leading edge in
+`headline` on a pushed page in the mobile view, and in the bar's centre in `headline` on a bottom sheet. A title widget,
+such as the editor's name field, stays at the leading edge. Past a back button a title keeps the bar's action inset
+clear of the button on either side.
+
+`test/lint/typography_test.dart` fails on `textTheme` anywhere in `lib/` but `typography.dart`, and on `fontSize:` or
+`fontWeight:` outside `lib/ui/`, except in the code editor, whose text follows the editor font-size setting.
+
+### Text Field Suggestions
+
+On Android, Flutter maps `enableSuggestions: false` to the visible-password input type, not only to "no suggestions"
+(`TextInputPlugin.inputTypeFromTextInputType` in the engine). Input methods then treat the field as a password: no
+clipboard panel, no Chinese layouts, and on some systems a secure keyboard. With the app's clipboard permission denied,
+that leaves no way to paste a link at all. Only the secret fields, `SecretTextFormField` and `FormRowSecretTextField`,
+ask for a password keyboard; a link, key, rule or regex field that should not be corrected sets `autocorrect: false`
+alone. `test/lint/text_field_suggestions_test.dart` fails on `enableSuggestions: false` or
+`TextInputType.visiblePassword` anywhere else in `lib/`.
+
+### Length Units
+
+Flutter lengths are logical pixels, the unit Android calls dp. Comments, test names, docs and reports give them in dp,
+as in `48 dp`, never px: a reader takes px for physical pixels and misjudges the size by the device pixel ratio. Write
+"physical pixel" in full where the code really works in them, as the hairline snapping in
+`lib/ui/list_row_separator.dart` and the Win32 frame metrics in `plugins/window` do; raster image sizes in
+`tool/` and CSS under `site/` keep px. `test/lint/length_unit_test.dart` fails on a number followed by px in `lib/`
+and `test/`.
+
+CI gates formatting: `dart format --output=none --set-exit-if-changed lib test
+tool plugins setup.dart` runs before `flutter analyze`.
+
+These directories are excluded from analysis:
+
+- `build/**`
+- `lib/l10n/intl/**`
+- `lib/**/generated/**`
+- `plugins/**`
+- the platform runner directories: `android/`, `ios/`, `web/`, `windows/`, `macos/`, `linux/`
+
+## Comments
+
+Comments are part of the code and some of them are load-bearing. What this repository limits is the useless and the
+frequent. Every comment that restates the code devalues the ones carrying real information, until readers skim past all
+of them — a file with three comments that matter is more readable than one with thirty.
+
+The two halves are enforced differently, because only one of them can be counted. Whether a comment is useless is a
+judgment, and it lives in the rules below and in review. Whether comments are too frequent is arithmetic, and
+`comment-density` measures it.
+
+### What a Comment Must Earn
+
+- Write one when it carries something the code cannot: a non-obvious constraint, an upstream or platform behavior being
+  worked around, a reason the next reader would otherwise get wrong, a coupling to a value defined somewhere else.
+- Never restate what the code already says. If the comment and the line below it convey the same thing, the comment is
+  noise.
+- Never narrate. Not what this diff changed, not what the code used to be, not the order you did things in. Version
+  history belongs in git and change rationale belongs in the commit message.
+- Never annotate line by line or statement by statement. A block that seems to need a comment per step needs better
+  names or a smaller decomposition instead — reach for structure before prose.
+- Prefer encoding the intent in structure and naming. A named mixin, type, or method that makes the invariant hard to
+  break beats a paragraph asking the next reader not to break it.
+- Delete commented-out code, stale version notes, and comments that only restate the code, whenever you edit the file
+  that contains them. This does not need approval.
+- These are not comments and are exempt from every rule here, including the density count: analyzer and linter
+  directives (`// ignore:`, `// ignore_for_file:`, `// coverage:ignore`), license and copyright headers,
+  code-generation markers, and comments inside vendored upstream code such as `lib/ui/open_container.dart`.
+
+### Density
+
+`tool/hooks/comment_density.sh` fails a file whose added lines are more than 5% standalone comment lines, ignoring
+diffs under 20 added lines so small edits are never caught. The number is calibrated on this repository's own history:
+healthy changes sit at or under 3.6%, while the core fix that prompted the gate ran 22.4%.
+
+It is a ceiling on frequency, not a target to fill. Do not read `core/`'s inherited mihomo density as a quota either —
+it is forked upstream code, not a house style.
+
+Three gates run the same script, and they do not have equal force. The `PostToolUse` hooks in `.claude/settings.json`
+and `.codex/config.toml` run after the tool and hand offending lines back as feedback; neither can undo the completed
+write. The `comment-density` pre-commit hook fails the commit, and it is the only hard gate that covers every tool.
+Behavior is pinned by `tool/hooks/comment_density_test.sh`, which CI runs through `tool/hooks/test.sh`.
+
+When a change genuinely warrants more, raise the ceiling for that run rather than working around it:
+`COMMENT_DENSITY_MAX=20 git commit`, or `SKIP=comment-density git commit` to step past it entirely.
+
+### Where Knowledge Belongs
+
+A comment is one of three destinations, and often the weakest. Pick by where the constraint would be violated, not by
+how important it feels.
+
+- **Assertable behavior goes in a test.** A test is the only form that cannot drift, because it fails when the behavior
+  it describes is broken. Prefer it over both a comment and a document whenever the fact can be checked in code.
+- **Repository-wide defaults, ownership, and invariants go in `.agents/*.md` or a `.agents/skills/*/SKILL.md`.** They
+  are violated from many files, so they must reach every future agent at session start. A comment in one file cannot do
+  that.
+- **A fact that is true only at one call site, and is not visible from that call site, is the one thing a comment does
+  better than a test or a document.** Its value is being in the reader's line of sight at the moment of the edit.
+  `lib/common/constant.dart` carries one: the delay-test concurrency cap is bound to `delayTestConcurrency` in
+  `core/delay.go`, and whoever changes that number must see the constraint on the same screen. This is the case a
+  comment is for; the bar is that no test and no `.agents/` entry could hold the fact instead.
+
+Both failure directions are real. Moving a local constraint into `.agents/` hides it from the person editing the line;
+leaving a repo-wide policy as a comment reaches only the reader of that one file.
+
+## Core API Safety
+
+- `core/Clash.Meta` is a fork of mihomo, and changes to it are budgeted for features, not repairs. Fixing a bug there is
+  low priority even when the bug is real and the fix is small: every patch is one more thing to carry across an upstream
+  rebase. Solve it on the FlClash side of the boundary and note the mihomo behaviour you are working around. Reach into
+  the submodule only for a feature that has nowhere else to live, or when the problem is one the FlClash patches
+  themselves introduced — and say which of the two it is in the commit message.
+- Do not expose direct filesystem deletion APIs through Core or helper IPC; use
+  a scope-specific cleanup API instead.
+- The desktop IPC socket in `plugins/rust_api` admits a Unix peer only when its effective uid is the app's own or root:
+  the socket lives in `/tmp`, and the Core connects as root whenever it runs setuid for TUN or under the Linux Helper.
+  A launch mode that runs the Core as any other user has to widen `admit` in `ipc/access.rs`, and Windows
+  keeps its identity check on the Dart side, which compares the named-pipe peer PID with the Core it launched.
+- Keep the shared `CoreMethodCall`/`CoreMethodResponse` JSON envelope structurally identical across Dart, Go, the
+  gomobile binding, and desktop IPC. Do not double-encode `arguments`, `result`, or event batches. A response whose
+  `file` is set was spilled to disk; a transport resolves it with `resolveSpilledResponse` before reading `result`.
+- `core/message.go` carries three event queues, and the split is load-bearing: state (loaded, geo-update,
+  route-changed), priority (every other event), and bulk (log, request, DNS). Priority and bulk evict their own oldest
+  entry under backpressure, except DNS, which enters the bulk queue through `enqueueState` so a lookup burst cannot push
+  out the request events the connection list is built from; state uses `enqueueState`, which never evicts, because a dropped `geoUpdate{updating:false}` leaves `isUpdatingProvider` stuck at true in the UI until
+  `UpdatingAction` sweeps it as stale minutes later. Do not merge the tiers or give state eviction semantics. `enqueueState` drops silently on a full
+  queue and must stay that way: reaching it means the host stopped reading, which `logDeliveryError` already reports,
+  and reporting it from the message layer feeds the same batcher.
+- Every method of the callback interfaces in `core/mobile` (`TunHandler`, `ResultHandler`) returns an `error`. gobind
+  clears a Java exception and hands it to Go only for a method that declares one; otherwise the exception stays pending
+  and the next JNI call on that thread aborts the process, so a throw in `protect`/`resolveUid`/`resolvePackage`/
+  `onResult` would crash unrelated code. `core/mobile` turns the error into the answer the system gives when it will not
+  help: `false`, `-1`, or an empty package name.
+- `TunHandler`'s hooks in `core/lib.go` check `callbacks` under `th.mu` before every call. `clear` drops the callbacks
+  while connections may still be resolving, and a call through the nil interface panics on a mihomo goroutine, outside
+  every recovery.
+- The Android bridge resolves an owner in two steps — `ResolveUid` then `ResolvePackage` — because mihomo fills
+  `metadata.Uid` from a procfs lookup that Android Q closed off. Collapsing them back into one call that returns only a
+  package name is what left every connection reporting uid 0, so `UID` rules matched nothing.
+- The desktop delivery path in `core/server.go` must not report failures through `logError`. A log event is published to
+  the log subscriber, batched, and handed back to `send`, so a send failure reported that way feeds itself; use
+  `logDeliveryError`, which writes to stderr and latches until a frame gets through or the next connection is installed.
+  A write that fails without putting a byte on the wire — host backpressure hitting `ipcWriteTimeout`, or a payload above
+  `maxIPCFrameSize` — drops that one frame and keeps the connection: the stream is still framed correctly, and tearing it
+  down here ends the read loop, and with it the Core process. A half-written frame whose write merely timed out is
+  resumed for as long as the stall lasts: Windows Modern Standby suspends the app while the Helper's Core keeps running,
+  so the host can stop draining for hours and still come back, and go-winio reports the expiry as its own `ErrTimeout`
+  rather than `os.ErrDeadlineExceeded`, which is why `send` checks `Timeout()`. The wait has no cap on purpose, and
+  `send` holds `writeMu` throughout, so every other frame — method responses and the single batcher goroutine behind
+  the event queues — waits behind the stalled one. Memory is bounded by the queues; what gives is delivery: the state
+  queue fills and `enqueueState` starts dropping, which is the case the `UpdatingAction` sweep above exists for. Nothing
+  on the Dart side restarts the Core over a stall: `CoreRpcClient` times each pending request out on its own and hands
+  the caller `null` (a `no_response` exception for message methods), and the sweep clears core-scope updating state
+  minutes later. Only a half-written frame that fails outright desynchronizes the stream, and that is the one case
+  `send` closes on.
+- Core method handlers are plain functions that return their answer, registered in the `methodHandlers` table in
+  `core/method.go` through the adapter matching their shape. `dispatchMethodCall` already runs every call on its own
+  goroutine and `handleMethodCall` turns a panic into an `internal_error` answer, so a handler blocks for as long as its
+  work takes and never spawns a goroutine just to answer. Work that outlives the answer goes through `safeGo`, which
+  recovers; a bare `go` puts a panic outside every recovery and kills the process, which on Android is the whole
+  application. The exported Android entry points in `core/lib.go` do not reach `handleMethodCall`, so each one carries
+  its own recovery.
+- A handler fails by returning an `error`: a `*MethodError` travels as it is and anything else under `core_error`. The
+  exception is `withMessage`, for the methods whose result the host reads as a message that is empty on success
+  (`_invokeMessage` in `lib/core/interface.dart`): there a plain error becomes that message and only a `*MethodError`
+  fails the call. Moving a method between the two changes what Dart receives.
+- `dialer.DefaultSocketHook` and `process.DefaultPackageNameResolver` are installed exactly once, by `installHooks` in
+  `core/lib.go`, and never cleared. mihomo checks `DefaultSocketHook` for nil once and dereferences it again when the
+  socket is created (`component/dialer/socket_hook.go`), so clearing it while a dial is in flight calls a nil func
+  value. Stopping the TUN swaps `activeTunHandler` instead.
+- `tunnel.AllProxies()` returns a shared, cached map — never modify it. The cache is invalidated by
+  `invalidateAllProxies` on `tunnel.UpdateProxies` and validated against each provider's `Version()`, so a rebuild
+  costs one read per provider rather than one per proxy. Anything else added to `tunnel/patch.go` that derives from the
+  proxy set needs both signals: the external controller can reload the config through `hub/route/configs.go` without
+  going through FlClash's `applyConfig`, so a hook on the FlClash side alone would miss a profile switch.
+- Core state that mirrors mihomo state goes stale at the next `applyConfig`, which replaces every proxy, provider and
+  rule. Read the tunnel instead of caching a snapshot of it: `lookupExternalProvider` kept one that was rebuilt only
+  when the host asked for the provider list, and the host asks after a successful setup and not after a failed one, so
+  an update ran against a provider the tunnel no longer held — downloading, writing to disk and reporting success
+  against nothing.
+- Selection writes take `selectMu`, not `configMu`. mihomo's `Selector.Set` has no lock of its own, so the writes need
+  mutual exclusion against each other and against `patchSelectGroup` — but not against a whole config apply, which is
+  what `configMu` made a proxy switch wait for, provider downloads included. `patchSelectGroup` takes `selectMu` under
+  `configMu`, fixing the order as `configMu` → `selectMu`.
+- Queueing for the delay-test semaphore and probing the node each get the full timeout in `handleTestDelay`. With one
+  shared deadline, a node that waited behind a saturated semaphore reached `URLTest` with almost nothing left, so a bulk
+  test of a large subscription reported whatever sat at the back of the queue as unreachable.
+- A delay test that the Core does not answer is a fault of the Core or the channel, never a verdict on the proxy:
+  `handleTestDelay` returns within its two timeouts on every path. `asyncTestDelay` therefore returns null instead of a
+  `-1` delay, and `ProxiesAction` leaves the last measurement in place and abandons the rest of the run. Writing a
+  timeout there is what made a reachable node read as unreachable whenever the host deadline beat the Core's.
+- Delay-test progress lives in `pendingDelayTestsProvider`, not as a sentinel value in `DelayDataSource`. A delay of 0
+  used to mean "testing", which let a result and the state of a test overwrite each other and left cards spinning
+  forever when the Core restarted. The run owns its keys and releases them in a `finally`, so nothing depends on a
+  reply arriving; core status leaving `connected` cancels every run in flight.
+- Some constants in `lib/common/constant.dart` mirror the Core and move with it. `delayTimedOutValue` is the `-1` that
+  `core/delay.go` reports for a delay test that ran out of time; any other negative value failed outright.
+  `downloadTimeoutDuration` matches mihomo's `resource.DefaultHttpTimeout`, which bounds the Core's provider downloads
+  end to end. `shareLinkSchemes` are the schemes mihomo's `ConvertsV2Ray` reads, less http(s), which is a subscription.
+- Anything on the mihomo side that is reached from both a user-triggered core method and mihomo's own background
+  scheduler needs its in-flight guard on the FlClash side. `updater.UpdateMMDB` and its siblings have none — only the
+  batch `UpdateGeoDatabases` does — and two concurrent runs close the mmap'd database twice, so `handleUpdateGeoData`
+  claims per resource and `updater.GeoUpdateHook` releases.
+- A failed `applyConfig` rolls the tunnel back to the default config, and that rollback is the whole recovery:
+  `handleSetupConfig` returns the error and stops there. Do not add a teardown on top of it — stopping the listeners
+  takes the app offline over a profile the user can still switch away from, and the error already reaches the host,
+  which is what surfaces the failure (`MessageException` on the Flutter side, the config-error toast on Android). Keep
+  an empty `config.yaml` out of the failure path — it is how the app says "no profile selected", and `loadConfig`
+  resolves it to the defaults.
+- Package `init` in the Android library runs while the `.so` is being loaded, so a panic there takes the application
+  down before it can report anything. `platform/limit.go` arms an fd-pressure probe and degrades to never blocking when
+  it cannot; keep that shape for anything else `init` sets up that correctness does not depend on.
+- No file in `core/` uses cgo: the only C in the Android library is the glue gobind generates during `gomobile bind`.
+  Android-only files take `//go:build android` and desktop-only ones `!android`, so `GOOS=android CGO_ENABLED=0 go vet`
+  checks the Android side without an NDK. Keep it that way; cgo in `core/` puts the NDK back in front of that vet and of
+  `go build ./...` on every developer machine.
+
+## Lifecycle Rules
+
+- Crash recovery is owned by `BootGuard` (`lib/common/boot_guard.dart`), and the signal it acts on is the persisted
+  `BootRecord`, never a crash reporter. The record is stamped `starting` before `startCore` and `running` once
+  `_initApp` finishes, so only a launch that died before reaching `running` is a failed launch — a crash after hours of
+  runtime, or a process the system reclaimed in the background, is not one. `ApplicationExitInfo` can only veto a
+  failure (user stop, low memory, signal, package change), never create one, and its timestamp is consumed through
+  `handledExitAt` so the same exit cannot be counted twice.
+- `BootGuard` is an Android-only mechanism and gates itself: on every other platform `evaluate`, `markRunning` and
+  `markClosed` return without touching preferences. The desktop has no `ApplicationExitInfo` equivalent to attribute an
+  exit, so a bare sentinel there would read a window closed on the disclaimer dialog, or a session ended by shutdown,
+  as a failed launch. Keep the platform check inside the guard; callers in `bootstrap.dart` and `SystemAction` stay
+  unconditional.
+- Recovery is graded: the first failed launch only skips `initStatus`, and `currentProfileId` is cleared only from
+  `crashRecoveryClearThreshold` consecutive failures on. Do not let a single interrupted launch write to the config.
+- 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. What flows back is
+  the revision-stamped `stopped` report, which Flutter mirrors with `setRunning(false)` and never answers with a
+  decision of its own.
+- Android `RunState` is derived in `ServiceStateMachine.publish`; do not assign it from a transition step, and do not
+  add a second "is it running" field beside `ServiceController.runtime`. Every divergence between the tile and the
+  service so far came from a copy that one path forgot to update.
+- 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.
+- Anything that probes through the outbound route is a `RoutedProbe` judged against `routeTrackerProvider` (Route
+  Consistency in `.agents/architecture.md`); the Core stamps every answer and publishes its picks, so do not add a
+  change signal, a trigger counter, or a `coreStatusProvider` watch of your own.
+- 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.
+- Safe mode (`SAFE_MODE` define, see the safe mode section of `.agents/architecture.md`) is consulted by each host
+  integration at its owner, never by rewriting the user's settings. `safeModeBuild` is for handles created before the
+  container exists; everything else reads `safeModeProvider` so a test can override it.
+- `Tray.hide()` is idempotent on all three desktop platforms and returns native state to "`show` was never called".
+  `AppTray.shutdown()` latches, so no later `update()`/`updateTitle()` can resurrect the icon once shutdown begins.
+  Keep it that way; a resurrected icon outlives `exit(0)` as a Windows ghost icon, because `setPreventClose(true)`
+  means `WM_DESTROY` never runs.
+- The `tray` plugin owns call ordering, idempotency, serialization, and unchanged-payload suppression. Application code
+  declares desired state through one `Tray.show(TraySpec)` call and must not add platform branches to work around
+  ordering. Platform branches in `lib/common/tray.dart` are only for deliberate product differences (macOS speed title
+  and group submenus); query `Tray.instance.capabilities` for ability differences.
+- Every native `show` returns whether the tray accepted the payload, and reports `false` instead of showing a broken
+  icon. `Tray` caches the payload signature only on `true`, so a rejected `show` is retried by the next update rather
+  than suppressed until restart. Windows accepts a payload the shell refused, as at sign-in, and retries the icon
+  natively until it lands, so `Tray` still treats it as visible and `hide` reaches native to delete an add that may
+  have landed. Any test that mocks the `tray` channel must return `true` from `show`.
+- Reading the Wi-Fi SSID is opt-in work, not ambient state. `ConnectivityManager` reads it only while `excludeSSIDs` is
+  non-empty, because that list is its only consumer through `suspendProvider`, and the read costs a blocking platform
+  call plus a location permission on Android and macOS. A second consumer must widen that gate, not drop it.
+- On Android the `wifi_ssid` permission is only `granted` once `ACCESS_BACKGROUND_LOCATION` is held too (Q+). Fine
+  location alone reads the SSID in the foreground but returns `UNKNOWN_SSID` once the app is backgrounded, which is
+  where on-demand spends most of its time. `getSsid` itself only needs fine location, so the split stays inside the
+  plugin.
+- No `wifi_ssid` implementation may answer `getSsid` on the platform thread. Android resolves through a network callback
+  with a timeout, Linux through `g_task_run_in_thread`, and macOS through `ssidQueue` after checking the location
+  authorization, because CoreWLAN reaches `wifid` over XPC and a wedged daemon would freeze the window. Windows is the
+  outstanding exception: `WlanQueryInterface` still runs inline, since replying off-thread there needs a window-message
+  hop that the plugin API does not provide.
+- The delayed DNS re-check `NetworkObserveModule.onLosing` posts is deliberately left un-deduplicated. The runnable
+  re-reads `networkInfos` and does nothing when `onLost` already dropped the network, `updateDns` calls into the Core
+  only when the resolved list or the preferred network changed, and `stop()` clears the handler queue, so a network that
+  reports `onLosing` repeatedly costs two comparisons per event. Holding the pending `Runnable` to `removeCallbacks` it changes no behaviour and adds
+  state that has to stay in sync with the map.
+
+## UI Isolate Work
+
+Everything the UI isolate runs synchronously shares a frame with build, layout and paint: 16 ms at 60 Hz, 8 ms at
+120 Hz. Computation may take as long as it needs anywhere else, so this rule is about where work runs, not how much of
+it there is.
+
+- Work that grows with the user's data (profiles, rules, proxies, groups, dialers, icons, connections) and can take
+  more than about 8 ms on the largest data the app expects runs in an isolate, through `compute` or `Isolate.run`.
+  Thousands of rules or proxies and hundreds of groups are in that range. `makeRealProfileTask` in
+  `lib/common/task.dart` and the backup tasks in `lib/common/backup.dart` are the existing shape.
+- Make the algorithm linear or cached first. Work superlinear in that data, such as a walk of the whole graph per
+  item, a scan of every group per group, or a list copy per inserted element, is a defect on any isolate; moving it
+  only hides the cost until the data outgrows the move.
+- Sending data to an isolate copies it on the sending isolate, so hand the task the smallest input it reads. A value
+  the UI reads synchronously, such as a sync provider watched in `build`, becomes an async provider with a loading
+  state rather than a blocking call.
+- drift runs SQL on its own isolate but maps rows into models on the caller's, so a watched query over a large table
+  costs the UI isolate on every emission, and any write to that table makes it emit again.
+- Bounded work stays where it is: a provider recompute that reuses a cache, a single-item update, a search filter over
+  a list sized for scrolling.
+- Decide on measurements taken at the expected maximum. A `flutter test` probe that counts provider recomputes, times
+  the provider body and hooks `debugOnRebuildDirtyWidget` shows what reruns and how it scales; its JIT timings are not
+  device numbers, so a case near the line is settled with a profile build. No gate checks this rule.
+
+## 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,
+plus a `GOOS=android` vet that covers the `android` files the first two exclude; verify cross-language
+protocol behavior through shared Dart contract tests under `test/core/` and native platform build checks.
+
+A Go test in `core/` that reaches `sendMessage` — directly, or through `handleStartLog` or `updater.GeoUpdateHook` —
+leaves events in the process-wide batcher, which flushes them up to `messageBatchInterval` later into whichever
+connection `captureFrames` has installed by then. Either keep the event out of the batcher or end the test with
+`settleMessageBatcher`. That batcher runs for the whole test binary and reads `conn` under `connMu`, so install a test
+connection with `swapConn`; a bare assignment races every event it happens to be delivering, and `go test -race` catches
+it in an unrelated test.
+
+Register fallback values for freezed params used with `any()` matchers.
+
+`tool/check_coverage.dart` enforces a total floor passed by CI plus per-group floors declared in `_groupFloors`. Raise a
+group's floor when new tests lift it; do not lower one to make a run pass.
+
+Every measured group needs a floor. A group the report measures but `_groupFloors` does not declare fails the run, so
+adding a top-level directory under `lib/` means adding its floor in the same change. Set a new floor at or just below
+the coverage the directory actually has; the point is to stop a slide, not to backfill tests before the directory can
+land.
+
+Prefer `coreHandlerProvider.overrideWithValue(CoreController.scoped(fake))` over `CoreController.test(fake)` in new and
+touched tests. `CoreController.test` claims the process-wide singleton, which makes a global read and a provider read
+resolve to the same fake, so it cannot fail on a call site that still reaches for the global. A test that does claim
+the singleton calls `CoreController.resetInstance()` in `tearDown`. It also only reaches the global `coreController`
+when nothing has read it yet: that is a top-level `final`, bound to whichever instance existed at the first read, which
+in a shared isolate is another file's.
+
+### Shared Test Isolate
+
+`tool/test.dart` imports many test files into one entrypoint, so process-wide state outlives the file that set it, and
+every file's `main()` runs before any test of the entrypoint does. Keep `main()` to declarations and
+`TestWidgetsFlutterBinding.ensureInitialized()`: a mock installed there is replaced by the next file's before a test
+sees it. Set up what the tests need in `setUp` or `setUpAll` instead, from the helpers that rebind the singletons:
+
+- `appPath` resolves its directories once per process. Point them at a test's directory with `await useAppPaths(dir)`
+  from `test/helpers/app_paths.dart`, not with a `PathProviderPlatform` fake, which only works while nothing has asked
+  `appPath` yet.
+- `preferences` opens its store once per process. Use `await mockPreferences(values)` from
+  `test/helpers/preferences.dart` rather than `SharedPreferences.setMockInitialValues` alone, which leaves `preferences`
+  on the store it already opened.
+
+Both cache the resolved value, not the future that produced it. A future completed in one test's fake-async zone runs
+its listeners in that zone, so a later test that awaits it never resumes. Await the helpers outside `testWidgets`
+bodies for the same reason.
+
+A test that only passes in a fresh isolate is leaning on a global it did not set up: `database_test.dart` once caught
+its write failures only because `currentAppLocalizations` threw before anything had loaded them. The script reruns such
+a file alone so it cannot fail the run, and lists it; fix it where it reads the global.
+
+Construct the Android lib handler with `CoreLib.scoped(fakeService)`. The `service` global is gated on `Platform.isAndroid`
+and is therefore null on every test host, so a `CoreLib()` built from it silently takes the null-service fallback on every
+path. `CoreLib.scoped` binds an explicit `Service` instead; reset the singleton with `CoreLib.resetInstance()` in `tearDown`.
+
+Three globals in `lib/common` reach real host state and carry a `@visibleForTesting` seam to stand in front of it:
+`AutoLaunch.launcher`, `listNetworkInterfaces` and `LinkManager.uriLinkStream`. Replace the launcher in particular — every
+`enable`/`disable`/`isEnabled` writes the actual autostart entry (a LaunchAgents plist, a `.desktop` file or a registry
+key), so a test that skips the seam registers the test binary on the machine that ran it. `updateStatus` returns early
+under `kDebugMode`, which is always true beneath `flutter test`, so its remaining branches cannot be reached from a test
+at all; `test/common/launch_test.dart` pins the early return instead.
+
+`pumpAndSettle` never returns on a page holding `EditorView` (what `EditorPage` embeds): the code editor blinks its
+caret forever, so frames keep being scheduled. Pump explicitly instead. `encodeYamlTask` and its neighbours in
+`common/task.dart` hand work to a real isolate through `compute`, which only runs outside the fake-async zone, so a test
+awaiting one needs `tester.runAsync(...)` between the pumps.
+
+The `@visibleForTesting` `database` setter in `lib/database/database.dart` deliberately does not close the instance it
+replaces. Tests inject `NativeDatabase.memory()`, which holds no file handle, and `Database.close()` is async while the
+setter is not, so closing there would either be unawaited or force the seam to become async for no gain. A test that
+does open a file-backed database owns closing it.
+
+`system.isAndroid` / `isMacOS` / `isWindows` / `isLinux` read `dart:io` `Platform` and cannot be overridden, unlike
+`debugDefaultTargetPlatformOverride`. A branch behind one of them is only ever exercised on a host that matches it, so CI
+(`ubuntu-latest`) and a macOS working copy measure different coverage for the same test. Assert host-agnostic behavior,
+and leave headroom under a group floor that covers such a branch.
+
+A platform decision that drives layout takes `isDesktop`/`isMacOS` as parameters and reads `system` only at the call site,
+so every platform's outcome is reachable from one host. `getWindowHeaderHeight` and `showsWindowHeader` in
+`lib/common/layout.dart` own the window header rule for both `WindowHeaderContainer` and `overlayTopOffset` — they must
+agree, or the content is offset by a header that is not there. `WindowHeaderBar` takes its height and slots as arguments,
+which is what lets `test/manager/window_header_test.dart` measure the Windows caption bar on a macOS host.
+
+A `Stack` under loose constraints sizes to its non-positioned children, and falls back to `constraints.biggest` only when
+it has none — so a bar that fills the window must keep every slot positioned. One non-positioned child is enough to
+collapse `WindowHeaderBar` to that child's width: the macOS title did exactly that, leaving the app name over the traffic
+lights and the raw window painted black beside it, while Windows, whose slots are all positioned, stayed correct.
+`WindowHeaderLayout` positions the header across the top for the same reason, and the macOS group asserts the bar's
+width, not just its height — a height-only assertion cannot see this.
+
+The same seam carries the two other places a platform decision changed what was built: `AppTray` holds `isMacOS`/
+`isWindows` as state — `AppTray()` fills them from `system`, `AppTray.forPlatform` is the test seam — and `OnDemandView`
+takes nullable `isAndroid`/`isMacOS` that fall back to the host. Every test names the platform it means, because
+`debugDefaultTargetPlatformOverride` does not move `system` and a suite that leaves it to the host asserts the macOS
+shape on a developer machine and the Linux one on CI. `WindowHeaderContainer` builds the caption buttons on every
+non-macOS host, so a test mounting it needs `TestApp` for `AppLocalizations` and a `window` channel mock that
+answers `isMaximized`/`isAlwaysOnTop` with a bool.
+
+Auto-dispose providers need a container-level hold before a test reads them back. `proxyGroupProvider`, `ruleProvider`,
+`itemsProvider` and friends mix in `AutoDisposeNotifierMixin`, so a `container.read` that no widget is currently watching
+rebuilds the provider from its override and silently discards whatever the code under test wrote. Add
+`container.listen(theProvider, (_, _) {})` in the harness, as `test/providers/action_test.dart` does for `scriptsProvider`.
+
+A field that constructs its own `ValueNotifier`, `TextEditingController`, `ScrollController`, `FocusNode`, `TabController`,
+`PageController`, `AnimationController` or `StreamController` must be released in the same file.
+`test/lint/disposable_field_test.dart` enforces this by scanning `lib/`, because no lint covers it: `close_sinks` only sees
+sinks, and nothing in the standard set tracks `ChangeNotifier` disposal. A field that genuinely outlives its owner goes in
+that test's `_allowed` set with the reason, not left bare. Controllers received as widget parameters belong to the caller
+and are out of scope.
+
+An `IconButton` whose icon is an icon needs a `tooltip`. It is the button's only accessible name — without it TalkBack and
+VoiceOver announce nothing and the desktop build shows no hover hint. `test/lint/icon_button_tooltip_test.dart` enforces
+it and skips exactly two shapes: an `icon:` holding a `Text`, which is already a visible label, and
+`views/dashboard/widgets/core_status_button.dart`, which takes its label from an enclosing `Tooltip` (a second test fails
+if that wrapper disappears). Reuse an existing string before adding one; a label that depends on state goes on the button
+inside the `ValueListenableBuilder`, not outside it, or the tooltip cannot follow the icon. A row of window buttons hidden
+behind `system.isMacOS` is unreachable from a macOS test host, so extract it — `WindowHeaderActions` is the pattern.
+
+A tooltip needs an `Overlay` ancestor at build time, not at hover time: `RawTooltip` builds an `OverlayPortal`, so a
+button whose `tooltip` has nowhere to go throws "No Overlay widget found" and takes its whole subtree down with it.
+Everything `buildManagerStack` wraps around `MaterialApp.builder`'s child sits *above* the app Navigator and therefore
+above the only Overlay in the tree. A manager that renders a tooltip — `WindowHeaderLayout` and its caption buttons are
+the case that broke Windows while macOS, which renders a bare title there, stayed clean — hosts its own with
+`Overlay.wrap`, spanning the window so the tooltip is not clipped to the widget that owns it. A test only reproduces this
+by mirroring that topology: build the widget from `MaterialApp.builder`, never from `home:`.
+
+A public top-level declaration that nothing outside its own file references is dead, and no lint catches it:
+`unused_element` covers only private ones, and a barrel `export` keeps a dead file compiling and off every
+"unused import" report. `test/lint/dead_file_test.dart` scans `lib/` for files whose declared names — types plus the
+`final appPath = AppPath()` singletons next to them — appear nowhere else, counting generated code as a consumer (a
+riverpod notifier is reached through its generated provider) and barrels as neither. Files publishing only extensions or
+typedefs are skipped: those are reached through the types they attach to, never by name.
+
+`CommonScaffold` adds the height of its docked search to `BottomInsetScope` around its body, so a page that reads
+`BottomInsetScope.of(context)` with the context it builds the scaffold from gets the inset without it, and the end of
+its content stays under the search field. Read it below the scaffold,
+inside `body: Builder(builder: (context) => ...)`. `test/lint/scaffold_bottom_inset_test.dart` enforces this by
+scanning `lib/`.
+
+Every reorderable list builds its drag proxy with `commonProxyDecorator`, which tells `DecorationListItem` it is lifted:
+the row drops its separator and rounds from its corners in the run to a card of its own as it lifts, and back as it
+drops. A list without it lifts a middle row with square edges. `test/lint/reorder_proxy_decorator_test.dart` enforces
+this by scanning `lib/`.
+
+A `State.dispose()` override must not await before `super.dispose()`. `StatefulElement.unmount` calls `dispose()` and then
+immediately asserts that `super.dispose()` already ran, so an `await` defers the call past the assert and every teardown
+throws "`…State.dispose failed to call super.dispose.`" in debug and profile builds. Declare the override as `void
+dispose()` and hand async teardown to `unawaited(...)`; `Future<void> dispose() async` compiles and is the shape that
+invites the bug.
+
+Use `ProviderContainer` directly for simple Riverpod provider tests, released with `addTearDown(container.dispose)`.
+Assert against the provider's generated public API, not its implementation, re-read source defaults before asserting
+them, and wait on provider futures or state changes rather than fixed sleeps. 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.
+
+## Running the App Locally
+
+- An agent starts FlClash on the host only as a safe mode build (`--dart-define=SAFE_MODE=true`, see
+  `.agents/commands.md`). A normal build takes over the host network, so the user runs it, never the agent.
+- Never end a FlClash process the agent did not start, and never kill by name (`pkill`, `killall`, a pattern on the
+  executable path): the user's own instance matches too. Record the pid of every process you launch, check with
+  `ps -o pid,command -p <pid>` that its executable is your own build output, and end only that pid.
+- Only a macOS or Android debug build has its own data directory; every other build shares the installed app's data
+  directory and single-instance lock, so it cannot start while the user's instance runs. `.agents/commands.md` lists
+  which builds are kept apart.
+
+## Commit Messages
+
+Subjects follow Conventional Commits and are enforced by the `commit-msg` hook in `.pre-commit-config.yaml`, which runs
+`tool/hooks/commit_msg.sh`:
+
+```text
+<type>[(scope)][!]: <description>
+```
+
+- Types: `feat`, `fix`, `docs`, `style`, `refactor`, `perf`, `test`, `build`, `ci`, `chore`, `revert`.
+- Scope is optional and lower case; use a comma to list several, as in `fix(core,android)`.
+- `!` before the colon marks a breaking change.
+- Descriptions start in lower case, omit the trailing period, and keep the whole subject within 100 characters.
+  Identifiers and acronyms keep their own casing, as in `fix(ui): AppBar text is truncated`.
+- `Merge`/`Revert` subjects and `fixup!`/`squash!` commits are exempt.
+- No `Co-authored-by` trailer crediting a coding agent, whatever that tool's own convention says. The history
+  records who owns the change, not which tool typed it; human co-authors are still fine. The hook rejects the
+  known agent identities.
+
+Write what the change does, not that something changed: `perf(views): stop redoing per-frame work in build`, not
+`Optimize more details`.
+
+Install the hooks once with `pre-commit install --hook-type pre-commit --hook-type pre-push --hook-type commit-msg`.
+
+### Fixup Commits
+
+A follow-up to a change that has not shipped in a stable release goes in as `git commit --fixup=<target>`, aimed at the
+commit that introduced what it amends.
+
+- Only stable tags (`vX.Y.Z`) close a commit. A target reached only by pre-release tags (`vX.Y.Z-pre.N`) is still open
+  for fixups, so do not steer away from it or flag it.
+- A commit a stable tag contains takes no fixup; land the follow-up as a regular commit. Check with
+  `git tag --contains <target> | grep -v -- '-pre'`, which must print nothing.
+- Asking for a fixup means creating the `fixup!` commit only. Do not run `git rebase --autosquash` or otherwise fold it
+  into its target unless the user asks for the squash.
+
+### Changelog Trailers
+
+`tool/changelog.dart` builds the user facing changelog from the commit history, so the trailers below are the copy that
+ships to users. The subject stays the developer facing summary and is only the fallback.
+
+```text
+feat(profiles): support per-profile override script
+
+Changelog: Per-profile override scripts
+```
+
+- `Changelog:` is the English entry. `Changelog: skip` drops the commit from the changelog entirely.
+- The changelog is English only. A `Changelog-<locale>:` or `Breaking-<locale>:` trailer fails the hook, because
+  translated release copy does not belong in the commit history. Translate after the fact if ever needed, not in the
+  commit message.
+- `Changelog-Type:` moves an entry into another group, for example to promote a `refactor` that users will notice. Valid
+  values are `breaking`, `feat`, `fix`, `perf`, `revert`.
+- `BREAKING CHANGE:` is required whenever the subject carries `!`, and its text becomes the breaking entry. A `!` commit
+  therefore needs two lines of copy: the footer for the breaking entry and `Changelog:` for the normal one.
+
+`feat`, `fix`, `perf`, `revert` and breaking commits are collected by default; every other type is dropped unless it
+carries a `Changelog:` trailer. Commits missing a trailer reuse their subject; for `feat`, `fix` and `perf` the hook
+says so without blocking.
+
+## Migrations
+
+An upgrade starts from the last release, not from the previous development build. Before writing a legacy reader, a
+data move, or a test for one, check that the state it reads shipped: `git tag --contains <commit>` on the commit that
+introduced it, or `git show <tag>:<path>` for the file as the release had it. A state that only ever existed between
+two releases gets no migration; a development install holding it may lose that setting or fall back to its default.
+
+A release that resets or rewrites settings, instead of reading their old shape, adds a step to `_upgrades` in
+`lib/common/migration.dart` under the next `upgradeVersion`. A step takes and returns the `Config`, runs once on an
+install that already had settings, and never on a new one. Leave `currentVersion` for changes to the stored format:
+backups carry it, and an older app refuses a backup stamped newer than its own, so bumping it for a reset would strand
+backups between devices on different releases.
+
+The database takes one migration step per release. The newest step in `lib/database/database.dart` has not shipped
+while `schemaVersion` at the last release tag is below its number; a schema change then goes into that step, raising
+`schemaVersion` and the step's condition together so a development install runs the step again, instead of adding a
+step of its own. Every operation in it checks the shape it finds, a missing table or column or a column under its old
+name, so it can run again on a database that went through part of it. Its tests start from the released shape.
+
+## Generated Code
+
+Do not manually edit generated files under:
+
+- `lib/l10n/l10n.dart`
+- `lib/models/generated/`
+- `lib/providers/generated/`
+- `lib/database/generated/`
+- `lib/ui/generated/`
+- `lib/l10n/intl/`
+
+After schema, model, or provider changes, run build generation and include focused tests when behavior changes.
+
+`lib/l10n/l10n.dart` is the one file that still imports `package:flutter/material.dart`.
+`intl_utils` hardcodes that import in its own template, so regenerating rewrites it and
+there is nothing to fix here; `test/lint/design_package_test.dart` exempts the generated
+l10n paths for that reason. It is harmless because the file only needs `Locale`,
+`BuildContext`, `Localizations` and `LocalizationsDelegate`, which the legacy library and
+`material_ui` both re-export from the same `package:flutter/widgets.dart`. Everything a
+human writes takes Material from `material_ui`; `cupertino_ui` is banned outright and
+survives only as a transitive dependency of `material_ui`.
+
+Strings live in `arb/intl_{en,zh_CN,ja,ru,fr,es,ko}.arb` — flat JSON, no `@` metadata. Add a key to all seven, then regenerate with
+`dart run intl_utils:generate`, which rewrites `lib/l10n/`. A key present in only some locales silently falls back to
+English at runtime, so add the translation rather than leaving it out.
+
+Labels for enum values go through the exhaustive switches in `lib/common/l10n_labels.dart`, never
+`Intl.message(<runtime string>)`. A key built from an enum name or a stored string is invisible to the analyzer, and a
+failed lookup returns the key itself, so a stale key ships as `routeMode_config` in the UI rather than throwing.
+`test/lint/dynamic_message_key_test.dart` fails on any `Intl.message(` in `lib` outside the generated code, and checks
+that every locale carries the same keys and has a display name.

+# Setting Changes
+
+A changed setting takes one of three paths. The path depends on who reads the setting and when it reads it, not on
+which page edits it. Choose the path when you add a setting or move one.
+
+| Path    | Who reads the setting                       | Watched provider                       | Acts                          | Effect                                     |
+|---------|---------------------------------------------|----------------------------------------|-------------------------------|--------------------------------------------|
+| Update  | Core, and Go can change it in place         | `updateParamsProvider`                 | `CoreManager`, automatically  | Patches the running config, no reload      |
+| Apply   | Core, only when it parses a config          | `setupPatchProvider`                   | `CoreManager`, automatically  | Rebuilds the profile and reloads the Core  |
+| Restart | Android service, when it starts             | `vpnOptionsProvider`                   | `VpnManager` asks the user    | Stop and start of the service              |
+
+Update and apply run on their own, debounced. A restart never does: rebuilding the tunnel cuts every connection
+through it, so `VpnManager` only shows a notifier and the user taps its restart action. A setting that only Flutter
+reads takes no path.
+
+## Update
+
+`CoreManager` hands each change of `updateParamsProvider` to `SetupAction.updateConfigDebounce`. `updateConfig` then sends
+`PatchClashConfig.toUpdateParams` to Go's `updateConfig` in `core/config.go`. That function writes the fields into the
+running config and calls the runtime setter for each one, or `updateListeners` for the inbounds. Nothing is re-parsed.
+
+The update path carries these fields:
+
+- From `PatchClashConfig`: `mode`, `log-level`, `mixed-port`, `allow-lan`, `ipv6`, `find-process-mode`,
+  `tcp-concurrent`, `unified-delay`, `external-controller`, `secret`, `geo-auto-update`, `geo-update-interval`,
+  `geox-url`, and the `tun` keys of `Tun.coreJson`: `enable`, `device`, `stack`, and `auto-route`, always on.
+- From other settings: `NetworkProps.authentication`, and `AppSettingProps.checkCertificate`, sent as
+  `skip-cert-verify`.
+
+On desktop, `updateListeners` rebuilds the TUN from the patched `tun`. Enabling TUN may need authorization first. When
+`requestAdmin` gets it newly granted, `updateConfig` restarts the Core instead of patching it. On Android,
+`updateListeners` skips TUN, so a `tun` update reaches the VPN only through a restart.
+
+To move a setting onto this path:
+
+1. Add it to Dart `UpdateParams` and `toUpdateParams`.
+2. Add it to Go `UpdateParams` in `core/protocol.go` and apply it in `updateConfig`.
+3. Reset it in `PatchClashConfig.setupOnly`. If you skip this, every change also reloads the profile. The
+   `PatchClashConfig.setupOnly` test in `test/models/config_test.dart` fails until its fixture changes the field and
+   `setupOnly` resets it.
+4. Keep writing it in `_makeRealProfileTask`, so a full apply hands the Core the same value.
+
+Prefer update whenever Go has a setter for the setting, because an apply reloads the whole config.
+
+## Apply
+
+`CoreManager` answers each change of `setupPatchProvider` with `applyProfileDebounce(silence: true)`. That call
+rebuilds the profile YAML and hands it to Go's `applyConfig` through `setupConfig`. The provider holds three values:
+
+- `PatchClashConfig.setupOnly`: the config with every field that update carries reset to its default.
+- `NetworkProps.appendSystemDns`.
+- `NetworkProps.bypassPrivateRoute` on desktop, where the task adds the private ranges to the TUN's final
+  `route-exclude-address`.
+
+A change to anything else in `PatchClashConfig` therefore reaches it. Today that is the DNS and TUN overrides (`dns`,
+`dnsOverrideKeys`, `tunOverride`, `tunOverrideKeys`), `hosts`, the extra inbound ports (`port`, `socks-port`,
+`redir-port`, `tproxy-port`), the dialer options (`keep-alive-*`, `disable-keep-alive`, `interface-name`, its mode,
+`routing-mark`), `geodata-loader` and `global-ua`. A new `PatchClashConfig` field written by `_makeRealProfileTask` lands here without further work. A value
+the profile build reads from another settings object has to be added to `setupPatchProvider`.
+
+An apply without `force` sends nothing when the md5 of the generated YAML has not changed. A value that only
+`SetupParams` carries never changes the YAML, so this path does not deliver it. `testUrl` is that case: Go's default
+health-check URL follows it only when some other change or a `force` apply reaches the Core.
+
+Profile content does not go through `setupPatchProvider`. `setupStateProvider` reads rules, groups and scripts from the
+database once instead of watching them. Content is applied explicitly by whatever changes it:
+
+- Profile editors call `autoApplyProfile` when they close.
+- Subscription updates, scripts and app-level providers call `applyProfileDebounce`.
+- A profile switch runs `fullSetup`.
+- A start applies again with `force` unless the last apply saw the same inputs (`_inputsApplied`), the `testUrl` and
+  `skipCertVerify` that only `SetupParams` carries included.
+
+## Restart
+
+`VpnService.handleStart` builds the tunnel once from `VpnOptions` and never reads them again.
+`ServiceController.start` uses `enable` to choose between `VpnService` and `ProxyService`.
+
+`vpnOptionsProvider` derives the options the service would start with now. `runningVpnOptionsProvider` records what
+the last listener start handed it. The route list is subtracted in an isolate by `vpnRouteAddressProvider`, which
+reruns only when the route lists or `bypassPrivateRoute` change, so `vpnOptionsProvider` is async: a start awaits it
+before recording, the Android Core awaits it before its first `syncState`, and the shared state keeps the last options
+while new routes compute rather than handing the service an empty list. `SetupAction` owns every start and stop: it
+sets the record on a start and clears it on a stop, on-demand SSID suspension included.
+
+`VpnManager` shows the notifier whenever a change leaves `VpnOptions.effective` different from the recorded options.
+Repeated changes refresh the same notifier instead of stacking new ones. Changing a setting back to the running value
+asks for nothing. The tap runs `SetupAction.restartVpn`: a stop, then a start, and only while a run is up.
+
+| `VpnOptions` field     | Taken from                                                    | The service reads it                   |
+|------------------------|---------------------------------------------------------------|----------------------------------------|
+| `enable`               | `VpnProps.enable`, off in safe mode                           | always                                 |
+| `stack`                | `Tun.stack`                                                   | with the VPN                           |
+| `ipv6`, `dnsHijacking` | `VpnProps`                                                    | with the VPN                           |
+| `allowBypass`          | `VpnProps`                                                    | with the VPN                           |
+| `accessControlProps`   | `VpnProps.accessControlProps`                                 | `enable`, `mode` and that mode's list  |
+| `systemProxy`          | `VpnProps.systemProxy`, off under local auth or safe mode     | with the VPN                           |
+| `port`                 | `PatchClashConfig.mixedPort`                                  | with `systemProxy`                     |
+| `bypassDomain`         | `NetworkProps.bypassDomain`                                   | with `systemProxy`                     |
+| `routeAddress`         | `Tun.routeAddress` and `bypassPrivateRoute`                   | with the VPN                           |
+| `mtu`                  | `Tun`                                                         | with the VPN                           |
+| `congestionController` | `Tun`                                                         | with the VPN                           |
+
+The service never reads the access list's sort and filter fields. `effective` resets them, along with every field
+the table does not mark as read, so changing them does not ask for a restart.
+
+To add a VPN option:
+
+1. Add it to Dart and Kotlin `VpnOptions` and to `vpnOptionsProvider`.
+2. If the service reads it only under a condition, put that condition in `VpnOptions.effective`, which mirrors
+   `ServiceController.start` and `VpnService.handleStart`.
+
+The notifier stays off while nothing runs, during on-demand suspension, in safe mode, and on desktop, where
+`VpnManager` is not mounted. When Flutter reattaches to a service that is already running, it records the current
+options, because the service does not report the options it was started with.
+
+## One Setting, Several Paths
+
+Each path watches its own provider, so a single setting can take more than one of them:
+
+- `mixedPort`: update moves the Core's listener; under the VPN system proxy, the restart notice follows.
+- TUN switch and stack: update rebuilds the desktop TUN. On Android the update reaches no TUN, and the restart notice
+  carries the stack.
+- MTU, congestion control and routes: Android's rows take the restart path; on desktop they are TUN overrides, applied
+  with the profile.
+- `bypassPrivateRoute`: apply on desktop, restart on Android.
+- Local authentication: update applies it to the inbounds. It also switches the VPN system proxy, which needs a
+  restart.
+
+## Choosing The Path
+
+For a new or moved setting, answer each question. More than one answer can be yes.
+
+1. Does the Android service read it when it starts? Then it belongs in `VpnOptions` and takes the restart path.
+2. Does the Core read it, and can Go change it in place? Then it belongs in `UpdateParams` and takes the update path.
+3. Does the Core read it only when it parses a config? Then write it into the generated config, and it takes the
+   apply path.
+4. Does only Flutter read it? Then it takes no path.
+
+Tests that hold these rules:
+
+- `test/models/config_test.dart` (`PatchClashConfig.setupOnly`).
+- `test/models/core_test.dart` (`VpnOptions.effective`).
+- `test/providers/state_derived_test.dart` (the setup patch).
+- `test/manager/core_manager_test.dart` (update against apply).
+- `test/manager/vpn_manager_test.dart` (the restart notice).
+- `test/providers/setup_action_test.dart` (running options, suspension, `restartVpn`).

+# Agent Skills
+
+Repo skills live under `.agents/skills/*/SKILL.md`, where Codex discovers them directly. Claude Code discovers them
+through the symlinks in `.claude/skills/`, one per skill, pointing back at the `.agents/skills/` directory. Both tools
+match a task against the skill `name` and `description`, then load the full instructions only when it matches.
+
+## Available Repo Skills
+
+- `localization`: hardcoded UI text scans, ARB updates, locale generation, and localization verification.
+- `ui-work`: Flutter UI, widgets, Material You styling, navigation surfaces, async feedback, and user-facing interactions.
+- `core-platform`: Core lifecycle/process ownership, Android services, Go event delivery, desktop IPC, platform managers,
+  VPN/TUN, and Windows Helper flow.
+- `pre-commit-quality-review`: lightweight triage before commits, with scoped structural review and user decisions on concrete regressions.
+
+## Authoring Notes
+
+- Add new repeatable workflows as `.agents/skills/<skill-name>/SKILL.md`, and add the matching
+  `.claude/skills/<skill-name>` symlink so Claude Code sees it too; remove both when retiring a skill.
+- Git stores the symlinks as links only where the checkout supports them. A Windows checkout needs
+  `core.symlinks=true` and Developer Mode, otherwise the links become plain files and Claude Code loads no repo
+  skill there; Codex is unaffected because it reads `.agents/skills/` directly.
+- Keep skill descriptions trigger-focused and start them with `Use when...`.
+- Keep long reference material in `.agents/*.md`; skills should link to it instead of duplicating it.
+- Put command permission rules in `.codex/rules/*.rules`, not in this file.

+name: core-platform
+description: Use when changing FlClash Core integration, lifecycle/process ownership, Go event delivery, Android services, desktop IPC, platform managers, build hooks, system proxy, tray, VPN/TUN, or the Windows or Linux Helper.
+---
+
+# 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.
+
+## Read First
+
+- `.agents/rules.md`: Core API Safety and Lifecycle Rules are binding. They carry the mihomo-fork patch budget, the
+  JSON envelope and `core/message.go` queue rules, gomobile callback rules, `BootGuard`, tray, and SSID rules, and every
+  lifecycle invariant (latest intent wins, desktop ownership through a `CoreProcessLease`, terminal `close()`,
+  optimistic Android commands arbitrated by `ServiceState`, callbacks are not user intent, `goAsync()` finishes once).
+- `.agents/setting-changes.md`: a setting the Core or the Android VPN reads is patched live, re-applied with the
+  profile, or left to a restart the user confirms; it says which, and what adding a setting to each path takes.
+- `.agents/architecture.md`: Core Integration, Lifecycle Ownership And Convergence, Core Protocol And Event Delivery,
+  Safe Mode, Build System, and Rust Helper Service describe the current mechanisms, including the Helper protocol,
+  the applied/coalesced/superseded outcomes, and the unconfirmed-exit lease.
+
+## Owners
+
+Every behavior here has one authoritative owner, and a change lands there:
+
+- 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 and Linux Helper HTTP contract:
+  `lib/core/desktop/helper_client.dart` and `services/helper/`.
+- Flutter orchestration: `lib/providers/actions/core.dart` and `system.dart`; application exit:
+  `SystemExitCoordinator`; UI/event observation: `lib/manager/`.
+
+An owner has more entry paths than the UI: provider calls, Quick Settings, notification actions, Always-on VPN, revoke
+callbacks, application exit, and crash/disconnect recovery all reach it. Always-on startup is explicit through
+`VPN_START_REQUESTED` and revoke through `VPN_REVOKED`; service creation or destruction is never read as intent.
+
+## Verification
+
+Focused tests live at the narrowest layer, and the matching commands are in `.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.
+- Helper: `cargo fmt --check` and `cargo test`; the `windows-service` feature only builds on Windows.
+
+State host gaps explicitly. Always-on VPN, VPN permission, system revoke, named-pipe peer identity, polkit and systemd
+on Linux, and Windows Service Control Manager behavior need their real platform even when portable tests pass.
+
+## Pitfalls
+
+- A `200` from Helper `/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 races a Core the Helper still
+  owns.
+- The Helper owns executable integrity: Core SHA256 validation and the protocol stay identical across Flutter build
+  modes, so a debug build is not exempt.
+- `plugins/setup/` is a build harness, not a Dart API plugin, and its hooks can trigger Go or Rust compilation
+  indirectly through Flutter platform builds; a missing toolchain fails `flutter test`, not only `flutter build`.

+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 in this repository, 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. Scan user-facing Dart text before opening many files. `flutter_intl` reads `arb/` and writes `lib/l10n/`:
+
+   ```bash
+   rg -n "[\\p{Han}]" lib -g '!lib/l10n/intl/**' -g '!lib/**/generated/**'
+   ```
+
+2. Inspect the smallest relevant call sites and nearby ARB keys.
+3. Add or update every source ARB:
+   - `arb/intl_en.arb`
+   - `arb/intl_zh_CN.arb`
+   - `arb/intl_ja.arb`
+   - `arb/intl_ru.arb`
+   - `arb/intl_fr.arb`
+   - `arb/intl_es.arb`
+   - `arb/intl_ko.arb`
+4. Replace inline strings with existing project accessors:
+   - Widgets with `BuildContext`: `context.appLocalizations.key` from `lib/common/context.dart`.
+   - Controllers/providers/non-widget code: `currentAppLocalizations.key` from `lib/common/app_localizations.dart`.
+5. Regenerate:
+
+   ```bash
+   dart run intl_utils:generate
+   ```
+
+6. Run `flutter analyze --no-fatal-infos` and `flutter test test/l10n test/lint/dynamic_message_key_test.dart`. The
+   lint test checks that every locale carries the same keys and that no `Intl.message` builds a key at runtime; labels
+   for enum values go through the switches in `lib/common/l10n_labels.dart`, as the ARB section of `.agents/rules.md`
+   explains.
+7. 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.

+description: Use when the user asks to commit, amend, or squash code, or requests a pre-commit structural quality review.
+---
+
+# Pre-commit Quality Review
+
+Check that iterative edits converged into a clear, cohesive, maintainable implementation before they become a commit,
+so later code review is not spent on basic structure. `AGENTS.md` and `.agents/rules.md` apply throughout. This skill
+grants no authority: commit, push, and history rewrites stay under the user's existing authorization, and silence is
+not consent.
+
+## Triage
+
+Most commits stop here. Decide from the change summary, the diff, and the local context it needs; never start with a
+repository-wide scan.
+
+- **Skip** formatting, mechanical renames, generated output, copy changes, and simple local fixes. They go through the
+  normal commit flow without extra confirmation. Say the review was skipped, never that it passed.
+- **Review** when a core implementation is replaced; when responsibilities, dependency direction, or public abstractions
+  change materially; when accumulated patches added branches, duplicate paths, or indirection; or when new code draws
+  responsibility boundaries. A small change can move a critical responsibility, so line count is not a trigger.
+- An explicit structural review request bypasses triage.
+
+The snapshot under review is the intended commit compared with its baseline:
+
+| Operation | Baseline |
+|---|---|
+| Regular commit | `HEAD` |
+| Amend | Parent of the commit being replaced |
+| Squash | Version preceding the agreed range |
+| Initial commit | Empty tree |
+
+Ask when the range or parent is materially ambiguous instead of assuming the whole branch. Read staged versions of
+partially staged files; an unstaged fix is not part of the pending commit. Preserve unrelated changes and partial
+staging.
+
+## Review the Final Structure
+
+Scope the review to the responsibility boundaries this change touched. Read the complete final implementation of the
+affected units and compare before and after, not only the last patch. Report issues this change introduced or
+worsened; untouched historical debt is not a pre-commit requirement. Follow a call or dependency path only as far as a
+concrete concern needs, and disclose missing essential context rather than claiming a complete pass.
+
+Focus on:
+
+- **Responsibilities and cohesion:** units mixing responsibilities that change independently; orchestration tangled
+  with implementation detail; responsibilities in layers that should not own them.
+- **Dependencies and abstractions:** reversed or circular dependencies, forwarding layers, abstractions that isolate
+  nothing; similar names or interfaces hiding different responsibilities.
+- **Complexity and readability:** nested conditions, repeated fallbacks, boolean parameter combinations, mutually
+  dependent helpers; names and decomposition that do not reduce reading effort.
+- **Duplication and consistency:** reimplemented existing capabilities, parallel implementations or duplicate state,
+  scattered ownership of error handling, cleanup, or state updates.
+- **Remnants:** obsolete branches, compatibility layers, unused parameters, commented-out code, comments the rewrite
+  invalidated; coupling that makes existing test boundaries hard to use.
+
+Not findings: length, a missing design pattern, naming taste, or anything without code evidence and a real
+maintenance cost. Do not add cross-layer coupling to remove a few similar lines, rewrite stable code for uniformity,
+or demand abstractions for speculative needs.

+Business logic, UI behavior, performance, security, platform compatibility, and full functional review are out of
+scope. Report an incidentally found serious defect separately through the normal defect workflow, without hiding it or
+widening this review.
+
+## Findings and the User's Decision
+
+A finding qualifies only when all three hold:
+
+- Before-and-after code and the necessary call relationships show this change introduced or worsened it.
+- The maintenance cost is concrete, such as updating one rule in two places or touching unrelated layers for one
+  responsibility. Clarity or elegance alone is not enough.
+- A minimal proposal fits existing constraints, with a benefit not offset by new coupling, indirection, or scope.
+
+With no qualifying finding, state the reviewed scope and conclusion in a sentence or two and continue under the
+existing commit authorization. Do not ask for confirmation because a review happened, and do not collect optional
+improvements into a suggestion list.
+
+With qualifying findings, finish the read-only review and independent checks first, merge findings that share a cause,
+and give for each: file, symbol, and location with how this change introduced it; the concrete maintenance cost; the
+smallest proposal with its scope and any behavioral impact. Then **pause before creating the commit and ask whether to
+optimize first; do not edit or commit until the user answers.** Attribute the pause to this skill by file path so the
+user recognizes their configured workflow, for example: "The structural issues above support consolidating the
+duplicate state-update paths. Should I make that change before committing?"
+
+Existing explicit authorization for these findings is enough to act without asking again. The user may accept all,
+some, or none. Keep accepted findings and tradeoffs in the task context only, and do not re-ask because files were
+restaged, a hash changed, or unrelated edits landed; reassess only when relevant code changes invalidate the tradeoff.
+
+## Resolve and Finish
+
+Once authorized, make the smallest adjustments that resolve the accepted findings while preserving behavior and task
+scope; explain separately if either must change. Verify only the accepted findings and the direct effects of the
+adjustments, without another search for improvements. Raise a new finding only with evidence that meets the threshold
+and exceeds the existing authorization.
+
+Before committing, recheck status and the actual staged diff so the pending snapshot matches what was reviewed, and
+review only the delta of later edits. Run the checks `AGENTS.md` requires for the change: `flutter pub get`,
+`flutter analyze --no-fatal-infos`, and the covering `flutter test` suites listed in `.agents/commands.md`. Reuse
+results that are still valid, rerun those a later edit invalidated, and never present results from an earlier snapshot
+as verification of the staged one. The `comment-density` and `commit-msg` hooks in `.agents/rules.md` still gate the
+commit.
+
+Report the reviewed scope, completed improvements or accepted tradeoffs, check results, and any verification limits.
+Claim the commit is done only after it exists.

+description: Use when changing FlClash Flutter UI, widgets, screens, Material You styling, icons or glyphs, shapes and corner radii, navigation surfaces, async feedback, or user-facing interactions.
+---
+
+# 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.
+
+## Conventions
+
+- Reuse the patterns of nearby widgets, providers, notifiers, and helpers before adding an abstraction, and keep to the
+  look the rest of the app has: Material You from `material_ui` as the base, with Apple's interaction conventions
+  (continuous corners, sheets that snap between detents, a floating tab bar) built on Material widgets rather than
+  Cupertino ones. Do not introduce a visual system for one screen or rewrite a layout the request does not need.
+- `.agents/rules.md` is binding here: the lint set (`child:` last, `const`, final locals), the superellipse corner API,
+  and the widget-test facts under Testing Rules (`pumpAndSettle` never returns on `EditorView`, `dispose()` must not
+  await, auto-dispose providers need a container-level hold, platform decisions are passed in as parameters).
+- A component that reads no provider, model or app string goes in `lib/ui/`; one built for an app feature goes in
+  `lib/widgets/`. The UI Layer section of `.agents/architecture.md` says how a `lib/ui` component gets app state.
+- Settings screens are built from the `ConfigToggleItem` family in `lib/widgets/config_item.dart`; the Settings Rows
+  section of `.agents/architecture.md` says when a file-local helper or a named widget is warranted.
+- Every icon lives in `lib/ui/icons/`, never the Material `Icons` font: reuse or add a glyph in `AppGlyphs` and show it
+  with `GlyphIcon`, or with `AnimatedGlyph` where it fills on selection. Glyphs are outlined, except inside a filled
+  button, where they take `fill: 1`. The Icons section of `.agents/architecture.md` covers shape roles, the stroke, the
+  fill animation, and when to fill.
+- Text sizes and weights come from `AppTextStyle` in `lib/ui/typography.dart`, Apple's iOS Dynamic Type scale, never a
+  Material `TextTheme` slot, a bare `fontSize`, or a `fontWeight`; the Typography section of `.agents/rules.md` has the
+  rule.
+- Modals dim what they cover with the Material 3 scrim (`ColorScheme.modalScrim`, `scrim` at 32%) and never blur it.
+  Every modal brings its own scrim, including one opened from inside another, so do not make a barrier transparent to
+  keep scrims from stacking.
+- A sheet's size belongs to its route, never to its content or call site: a bottom sheet rests at
+  `SheetProps.detents`, a side sheet is as tall as the window and as wide as `ModalSideSheetRoute` makes it from
+  the window width (`lib/ui/side_sheet.dart`, pinned by `test/widgets/side_sheet_width_test.dart`), and a form sheet
+  is a card `FormSheetRoute` caps in width and height (`lib/ui/form_sheet.dart`). Do not wrap a sheet's content in a
+  fixed width or height to resize one sheet.
+- A form with more than one value opens with `showFormSheet` and lays its values out in `FormRow`s, never as labeled
+  fields in a `CommonDialog`; a prompt for one value stays an alert. Forms in `.agents/architecture.md` has the rule.
+- A modal scrolls only once the window and keyboard leave it no room, and then through one scroll view: `CommonDialog`
+  caps its body at nothing but the space it is given, and a multi-line field in a dialog or sheet grows with its text
+  (`maxLines: null`) rather than scrolling inside a line count. With the keyboard up, a bottom sheet keeps what it
+  shows above the keyboard, rising past its tallest detent as far as a peek below the top (`_top` in
+  `lib/ui/snap_sheet.dart`).
+- The keyboard animates `MediaQuery.viewInsets` every frame. Read MediaQuery by aspect (`paddingOf`, `viewInsetsOf`)
+  rather than `MediaQuery.of`, and wrap the page of a new route type in `KeyboardInsetHold`; Keyboard Insets in
+  `.agents/architecture.md` has the reasons.
+- A page loads what it shows as it mounts, never once its route has settled; what waits out a transition is work
+  that repeats, such as a live feed's refreshes (`RouteMotionHoldMixin`), and the rows past the viewport
+  (`arrivalScrollCacheExtent`). Page Arrival in `.agents/architecture.md` has the rule.
+- A page that waits on its data shows nothing until all of it is ready (`NullStatusSwitcher.isLoading`), and a load
+  that can run long adds its illustration as `loadingStatus`, never a skeleton screen; Page Arrival in
+  `.agents/architecture.md` has the rule.
+- App bar buttons reach `CommonScaffold` as data (`primaryAction`, `iconActions`, `menuItems`) so it can fold them into
+  its overflow menu; App Bar Actions in `.agents/architecture.md` has the rule.
+- A row's secondary actions open from a context menu, never a trailing more button; a list whose rows have one
+  reorders in a sort mode, any other by a long press on the row. Row Actions And Sort Mode in `.agents/architecture.md`
+  has the rule.
+- Quick edit belongs only on a page that edits a whole list or section, or one isolated item; never on one that edits a
+  part of something other settings also write. Quick Edit in `.agents/architecture.md` has the rule.
+- A page or sheet opens on the navigator of the context it comes from, never on the root navigator unless Where A
+  Route Opens in `.agents/architecture.md` allows it.
+- User-facing text goes through ARB; use `localization` when text changes are non-trivial.
+- An asynchronous control keeps four things apart: authoritative provider/domain state; display-only state such as a
+  minimum progress duration; tap policy while work or a display hold is active; and failure/disposal cleanup, in
+  `finally` for animations and timers. `CoreStatusButton` and the proxies delay test action are the reference implementations,
+  described under User-Facing Core And Delay Feedback in `.agents/architecture.md`.
+
+## Corner Radii
+
+All corner radii come from `lib/ui/shape.dart`: a token, a derived value, or a named off-scale value passed to its
+builders. Never write a bare radius literal at a call site.
+
+The scale is picked by the component's **shortest side**. A radius that reads as a soft card at 64 dp tall
+reads as a pill at 24 and as a square at 400, so one radius everywhere is the wrong kind of consistency.
+
+| Token | Value | Shortest side | Use |
+| --- | --- | --- | --- |
+| `none` | 0 | - | square edges, and the flat side of a grouped run |
+| `xs` | 4 | inset blocks | tiles clipped inside an already rounded surface |
+| `sm` | 8 | up to 48 | chips, thumbs, swatches, small square tiles |
+| `md` | 16 | up to 64 | interactive chrome: inputs, menus, buttons, popups |
+| `lg` | 20 | 64 to 180 | mid-size cards: dashboard tiles, proxy node cards |
+| `xl` | 24 | full-bleed | anything spanning the whole width: list rows, grouped runs, group headers |
+| `xxl` | 28 | over 200 | sheets, full-screen containers |
+| `full` | 1000 | - | pills and circles: buttons, tracks, indicators, progress, avatars |
+
+- `AppCorner` holds the scale as `double`; `AppRadius` mirrors it as `BorderRadius` with `all`, `top`, and `vertical`
+  builders; `AppShape` mirrors it as `RoundedSuperellipseBorder`, `full` included, plus `circle`, `input`, and the
+  `all`/`top`/`vertical`/`of` builders. Use `AppShape.full` for pills, never `StadiumBorder`; the Corner Radius
+  section of `.agents/rules.md` explains why and lists the superellipse API per layer.
+- `AppCorner.fit(shortestSide)` snaps to the largest token at or under one third of the shortest side. Use it whenever
+  the size comes from a `LayoutBuilder` or scales with text.
+- `ThemeData.withAppShapes` in `lib/ui/shape.dart` already applies the scale to card, dialog, bottom sheet, snack
+  bar, chip, menu, input, FAB, navigation indicator, progress, and the filled, text, outlined, elevated, and icon
+  button themes. Do not restate those shapes at call sites, and
+  leave `InputDecoration.border` unset so inputs inherit `AppShape.input`.
+- Colors of surfaces follow `.agents/surfaces.md`: fills by `SurfaceLevel`, no structural borders, and
+  `primaryContainer` only on a selected item.
+
+`xl` and `lg` exist because one token cannot serve both size classes. A full-bleed surface is wide and short, so its
+corner must be larger than its height alone suggests or it stops reading as a card; everything full-bleed shares `xl`
+(`CommonSelectedListItem`, the profiles card, the outer corners of a grouped run in `DecorationListItem`, the proxy
+group card in `lib/views/proxies/list.dart`) and does not use `fit()`. This is the one deliberate overshoot of the
+one-third rule; the value stays under half a standard row so nothing clamps and every full-bleed surface renders the
+same radius. `lg` is for mid-size cards that are not full-bleed: a proxy node card in the tab view at
+`ProxyCardType.compact` is only about 64 tall, which caps its radius at 21, so `xl` would break on a setting the user
+can change at any time while `lg` clears both heights and the smallest dashboard tile.
+
+Outlined inputs use `AppInputBorder`, not `ShapedInputBorder` from `package:material_ui`. The package border subtracts
+the floating label's notch as a flat band along the top edge, which takes the corner curve with it at any radius from 8
+up. `AppInputBorder` clips the notch region and paints the full superellipse through it, as Flutter's own
+`OutlineInputBorder` does by shortening the arc. It needs no `contentPadding` compensation.
+
+Nested radii are derived, never tokens: concentric corners need `outer = inner + inset`, so name the inset and compute
+the outer value, as `_cardRadius` in `lib/ui/popup.dart` does. Adding a token for one of these is how a scale grows without
+bound. A card that also stands on its own elsewhere keeps its token when nested: the proxy node cards inside a proxies
+list group stay `lg` like those in the tab view, since deriving them from the group card's `xl` left them at 14, smaller
+than every other card in the app.
+
+A component the scale does not fit keeps its own value instead of growing the scale: name it once in the file and pass
+it to the `all`/`top`/`vertical` builders, as `_itemShape` in `lib/ui/sidebar.dart` does with 10, between the
+chip-sized `sm` and the near-pill `md` on a 40 tall row, and `_dialogCorner` in `lib/ui/shape.dart` does with 34, the
+corner of an iOS alert. Reach for this only once the table and `fit()` are ruled out.
+
+## Verification
+
+- A behavior change gets a focused widget test covering rendering states, taps, scrolling, and empty/error states,
+  including the exception path of any async action. Run `flutter analyze` and `flutter test test/widgets/` plus the
+  tests of the touched view.
+- The scans in `test/lint/` fail on the common UI mistakes and run as part of `flutter test`: an `IconButton` whose
+  icon is an icon needs a `tooltip`; a field that constructs its own controller, notifier, or focus node is released in
+  the same file; a public declaration nothing references is dead. `.agents/rules.md` explains each rule and its
+  allowlist.
+
+## Pitfalls
+
+- 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.
+- Do not manually edit generated localization or provider files.

+# Surfaces
+
+FlClash draws structure with fills and keeps color for state. A surface stands out from what it sits on by a step in
+lightness, never by a border. Color appears where something is selected, on, failing, or the one action a screen is
+for. The dashboard set this direction; every other screen follows it, and Material components keep their behavior
+but give up their tonal container fills.
+
+## Levels
+
+`SurfaceLevel` in `lib/ui/surface.dart` names four depths. Each surface takes the level one deeper than the one
+it sits on, which `SurfaceScope` passes down the tree.
+
+| Level   | Light                     | Dark                      | Holds                                                   |
+|---------|---------------------------|---------------------------|---------------------------------------------------------|
+| `page`  | `surfaceContainer`        | `surface`                 | scaffold body, sheets                                   |
+| `card`  | `surfaceBright`           | `surfaceContainer`        | cards, grouped runs of rows, light-mode floats          |
+| `block` | `surfaceContainer`        | `surfaceContainerHigh`    | unselected segments, tiles and wells in a card          |
+| `inset` | `surfaceContainerHighest` | `surfaceContainerHighest` | small marks inside a block: glyph wells, badges, tracks |
+
+Light mode alternates gray and paper: a near-white card on a gray page, a gray block in the card. The card is tone 98,
+not pure white, and the page tone 94: pure white beside a tinted gray made the white glare and the gray look soiled. Dark mode only
+lightens, because a darker step inside a lighter surface reads as a hole rather than a layer. `inset` is the floor;
+nothing nests below it, so a design that needs a fifth level needs fewer containers instead.
+
+- A widget never picks its level at the call site. `CommonCard` and the other shared surfaces read
+  `context.raisedSurfaceLevel` and wrap their child in `SurfaceScope`, so the same row is white on a page and gray
+  inside a card. A branch on `isInBottomSheet` or on where a widget is placed to choose its fill is the bug this
+  replaces.
+- Sheets are `page` level, like a page, so a section looks the same in a sheet and in a page. In dark mode a sheet
+  presents a level up, as iOS presents a sheet on its elevated backgrounds: `ColorScheme.elevated` lifts every
+  surface role by the step from `page` to `card`, so the sheet's page takes the tone of the cards it covers and every
+  level inside it follows. Under pure black the sheet takes the plain dark scheme instead, which is the same step up
+  and keeps the seed's tint that a lift from black would lose. `ElevatedColorScheme` carries the result and the sheet
+  routes apply it through `ElevatedSurfaceTheme`; a sheet opened from a sheet keeps the same lift. A scrim barely
+  darkens a dark page, so a dark sheet at the page's own tone read as more of the page rather than a layer over it,
+  a covered sheet's peek vanished, and on black the edge and corners went with it. Light mode keeps its levels,
+  because the scrim already sets a light sheet apart.
+- What floats over content, dialogs, menus, popups, the mobile dock, toasts, takes `SurfaceLevel.floatingOf`: `card`
+  in light, `block` in dark. A shadow does not show on a dark page, so a float has to come out lighter than the cards
+  it covers, and its content scopes to that level so a block inside still steps away from it.
+- Shadows mark what floats, plus the dashboard cards. Cards in a scrolling list have none; a grid of proxies with a
+  blurred shadow each costs raster time for no extra layering. A render object that paints a shadow itself draws it
+  with `drawRSuperellipse`, as `ShapeDecoration` does: Impeller blurs a superellipse in one analytic pass, but a path
+  through an offscreen Gaussian blur on every frame, which made the shadows the largest raster cost of an opening menu.
+
+## The Seeded Scheme
+
+`seededColorScheme` in `lib/ui/color.dart` builds every app scheme: Material's scheme for the seed and the
+`ColorStyle` picked in the theme settings, with three groups of roles replaced. Everything else stays Material,
+including `toPureBlack` applied after it.
+
+The four styles each change something a reader sees at once. Material's nine variants mostly moved secondary and
+tertiary, which the app barely shows, so most of them looked alike once surfaces stayed gray.
+
+| Style        | Material variant | Primary           | Surfaces                        |
+|--------------|------------------|-------------------|---------------------------------|
+| `vivid`      | content          | the seed          | near gray                       |
+| `tinted`     | content          | the seed          | the seed's hue, up to chroma 10 |
+| `soft`       | tonal spot       | Material's, muted | near gray                       |
+| `monochrome` | monochrome       | black or white    | gray                            |
+
+
+- **Surfaces stay near gray.** Each `surface*` role keeps Material's tone but its chroma is capped at 3, the light
+  `surface` and `surfaceBright` at 1.5, and `outlineVariant` at 4. Material tints neutrals by the seed (content
+  divides the seed's chroma by 8), so a yellow, green, or rose seed tinted the whole page. `tinted` is that wash
+  chosen on purpose and made even: every surface takes the seed's hue at a sixth of its chroma, capped at 10, so a
+  gray seed stays gray and any vivid one tints about as much.
+- **`primaryContainer` comes from the primary palette.** It is primary's hue at tone 90 in light and 30 in dark,
+  with `onPrimaryContainer` at 30 and 90, and the pair's chroma is capped at 48. Content and fidelity otherwise put it
+  at the seed's own tone: a yellow seed filled it with pure yellow, a red seed with something that read as an error,
+  and dark mode with a light block under light text. The cap matters for light, chromatic hues: yellow at tone 90 is
+  still close to full strength.
+- **`vivid` and `tinted` keep the seed as `primary`**, as an Apple accent color does: the color picked in the theme
+  settings is the color of every check, switch, and filled button. Light holds the seed's tone between 35 and 60, so
+  white text on it keeps about 3:1 and a near-black seed still reads as a color; dark lifts it 3 tones, as iOS lifts
+  its system colors, within 50 to 75, and puts dark text on it above 60. Material sets primary at tone 40 and 80 for
+  any seed, which turned iOS blue into navy in light and a pastel in dark. `soft` and `monochrome` keep Material's
+  primary, since moving away from the seed is what they are for.
+
+## State
+
+Color marks the one item that differs, never the structure around it.
+
+- **Selected**, one of several rows, cards, or tiles: the item keeps its level's fill and a primary mark says which,
+  as iOS checks the option picked from a list. A row in a grouped run takes `SelectionCheck` at its edge; a card that
+  stands on its own, a profile or a proxy, and a tile take the filled `SelectionBadge`, which holds its own beside a
+  40 dp icon well where the bare check read as small and thin (`lib/ui/selection_mark.dart`). `CommonCard.isSelected` only reports the state to
+  accessibility. Fills were tried and rejected: a wash of primary landed on a gray that did not read as a choice, and
+  `primaryContainer` read as a warning under rose seeds in light and as a heavy slab in dark, muddied the translucent
+  marks on it, and cut a grouped run in two.
+- **Multi-select** in edit mode: the circle checkbox is the mark; the row stays at its level.
+- **Proxy groups** have two states in URLTest and Fallback: the check badge marks the proxy traffic goes through, in
+  every group type, and a pin badge (`SelectionBadge.preferred`) marks the preferred proxy (mihomo's `fixed`): filled
+  like the check while the group uses it, tonal while the group has fallen back to another proxy, which carries the
+  check.
+- **Chosen segment** in a connected button group, a mode switch, or a run of compact choice chips
+  (`CommonCard.fillsSelection`): solid `primary` with `onPrimary`, as the dashboard outbound mode does. Only one
+  segment per group.
+- **Error** on a row or card: `errorContainer` with `onErrorContainer`, no border.
+- **Status** values (delay, availability, success, warning): the color goes on text, a glyph, or a small chip, never
+  on a whole card. `success` and `warning` come from fixed green and orange palettes that ignore the seed, like
+  Material's `error`; harmonizing pulled orange toward red under rose seeds until warning and error matched. Text takes
+  tone 40 in light and 80 in dark, a chip takes `successContainer`/`warningContainer` (90/30) with the `on` role
+  (30/90). A delay under 600 ms is success, above it warning, a failure error: `ColorScheme.delayColor`.
+- **Destructive** action in an alert: `ColorScheme.destructive`, iOS 27's systemRed in both modes, not `error`. A
+  menu's `danger` item still takes `error`.
+- **Data series** on one chart: the first is primary, the second primary at 45% over the card
+  (`DashboardColors.series2`), so they differ by lightness under any seed. Tertiary is not a series color.
+- **Text**: titles and values `onSurface`, labels and secondary lines `onSurfaceVariant`. `outline` is not a text
+  color, and a value is never tinted primary.
+- **Marks** that only identify, a country badge, a group or service icon, a source avatar, sit on a neutral well with
+  `onSurfaceVariant`.
+- `primaryContainer`, `secondaryContainer`, and `tertiaryContainer` are neither surface nor selection fills. Keep
+  them out of cards, rows, marks, and navigation indicators.
+
+## Borders That Stay
+
+- **Focus**: a 2 dp primary stroke while a surface has keyboard or remote focus. TV navigation depends on it, and a
+  fill change alone is too faint to follow from a couch. A card, a grouped row above all, rings only focus a key moved
+  there (`FocusMovedByKey`), or any focus while a remote drives the app: a tap or a click puts focus where the reader
+  is already looking, a field's caret already marks it, and the ring then read as a selection box around the row.
+- **Inputs**: a form's field is a bare `FormRowTextField` at the end of a grouped `FormRow` whose title labels it, as
+  iOS and macOS set one, with no stroke or fill of its own. A field among filled controls takes their fill, one level
+  above its surface, through `FilledInputTheme`. An alert's fields, because they sit over its pill buttons, as
+  UIAlertController sets them: as wide as the buttons, in their fill, with their text in line with the title and the
+  label as the placeholder (`CommonDialog.hasFields`); a field under a filled block of text in an alert takes the
+  block's width and corner instead. The custom color's hex field, because its card holds only fills, the color
+  previews, where an outline was the one stroked thing. Search fields are filled pills. A sheet's docked search,
+  because the list scrolls under it: it floats like the dock, with the floating fill and the dock's shadow, or the
+  dock's glass. The editor's find bar, because its fields sit in a row of filled pill buttons: they take the buttons'
+  fill, one level above the bar. All of these stroke only while focused. Any other field, one standing alone on a page,
+  is outlined, with the floating label notched into the stroke: `ThemeData.withAppShapes` gives every input
+  `AppShape.input`, so call sites leave `border` unset. A lone field is never filled: here a fill means structure, so
+  one read as one more card or row, and in light mode the hover overlay brought it down to the page's own tone. No
+  field counts its characters, as none does on iOS or macOS; a length limit holds through its formatter. Material
+  strokes a filled field's whole outline in `onSurfaceVariant`, which ringed the pill brighter than anything else in a
+  dark sheet.
+- **Window chrome**: the desktop sidebar's inner edge and the title bar's bottom edge draw a divider where they meet
+  the content. The chrome fill alone left the edge to a four-tone step, which read as a smudge rather than a boundary.
+
+Nothing else draws an outline. Rows in a grouped run are separated by the hairline from `lib/ui/list_row_separator.dart`, which divides
+one surface and does not outline it. Record lists, requests, connections, logs, and DNS queries, are not grouped: they
+run to thousands of tall rows, and one card that long reads as a slab rather than a group. A stacked row of three or
+four lines is already its own block, so each is a card of its own, `RecordListItem`: the raised fill at `xl`, 16 dp
+from the edges and 8 dp from the next, as the profile cards sit. Every card takes the same fill, so the warning and
+error tints on a label still stand out, where a fill on every other row competed with them; rows on the page split by
+a full-width divider were the one structural line left on screens otherwise drawn with fills. Laid out as a table,
+where a row is one line read across many columns, they drop the gap and give every other row the raised fill, inset
+and rounded like the column header, so the eye keeps its row; the dashboard's table does the same.
+
+Every divider takes its color from `ThemeData.withAppSurfaces`: `onSurface` at 14%, never `outlineVariant`. A
+translucent line keeps the same contrast on the page, a card, or the chrome, in both modes; `outlineVariant` stood out
+twice as much on the dark page as on the light one and carried the seed's tint.
+
+## Navigation
+
+- The desktop sidebar and title bar are window chrome, `ColorScheme.chromeSurface`: `surfaceContainerHighest` in
+  light and `surfaceContainerLow` in dark, four tones from the page either way, with a divider along the edge that
+  meets the content. At `page` level the sidebar merged with the content. In dark the chrome stays below `card`, so
+  cards still stand out from it. The pane the sidebar opens over the content takes the same fill and edge, plus a
+  shadow.
+  The selected destination keeps its neutral fill and primary bar, which already marks it with color.
+- The mobile dock and the docked navigation bar are floats; their indicator is a neutral platter one level above
+  them, and the selected destination's content takes primary, as iOS's tab bar marks its selection.
+- With Liquid Glass on (Theme settings), the dock, the buttons of a page's bar, a sheet's docked search, popup
+  menus, and alerts are glass from `lib/ui/liquid_glass.dart` instead of a fill, and the dock's platter takes the
+  secondary hue and chroma at tone 90, or at tone 4 in dark, which sinks it below the bar as iOS 27 does.
+- The proxies page's group tabs are compact choice chips, the current group in the chosen segment's solid `primary`.
+  Once they overflow, a tonal button at their end opens every group as a popup menu, the current one checked and
+  scrolled into view. A profile can carry dozens of groups, so the menu stops at seven rows and half of the next.
+
+## Where It Lives
+
+- `lib/ui/surface.dart`: `SurfaceLevel`, `SurfaceScope`, `context.surfaceLevel`, `context.raisedSurfaceLevel`,
+  `ColorScheme.chromeSurface`, and `ThemeData.withAppSurfaces`, applied next to `withAppShapes` wherever the app
+  builds its theme.
+- `lib/ui/color.dart`: `seededColorScheme`, the status palettes, and `delayColor`.
+- `lib/views/dashboard/style.dart`: `DashboardColors` maps `page`, `card`, `tone`, and `tone2` onto the levels and
+  adds the dashboard's switch, series, and status colors.
+
+## Checking A Change
+
+Render the touched screens in light and dark, on a phone width and a desktop width, before and after. A throwaway
+widget test does it: pump `HomePage` or the view inside a `RepaintBoundary`, load Roboto with `FontLoader` so text
+gets real glyphs, and write `RenderRepaintBoundary.toImage` to a PNG outside the repository. Look for a surface that
+matches the one it sits on, which means it skipped `SurfaceScope`, and for a tonal container fill that survived on a
+card or row.

+# Worktrees
+
+Claude Code, Codex, and Gemini each create git worktrees. `tool/worktrees.sh list` shows every worktree with its
+owning tool and whether it holds uncommitted work; `tool/worktrees.sh prune` removes the clean ones and keeps
+dirty ones unless `--force` is passed. `.claude/worktrees/` is ignored by git; `.claude/settings.json` is tracked.

+# 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/setting-changes.md](.agents/setting-changes.md): whether a changed setting is patched live, re-applies the
+  profile, or asks for an Android VPN restart.
+- [.agents/surfaces.md](.agents/surfaces.md): fill levels, selection and status colors, and the few borders that
+  remain, for any change to how a surface is colored.
+- [.agents/agent-config.md](.agents/agent-config.md): how to choose between `AGENTS.md`, `.agents`, skills, Codex config,
+  command rules, and hooks.
+- [.agents/worktrees.md](.agents/worktrees.md): worktree hygiene across Claude Code, Codex, and Gemini.
+- [.agents/flutter-upgrade.md](.agents/flutter-upgrade.md): SDK-pinned workarounds to recheck before changing the
+  Flutter version.
+- [.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.
+- The request sets the scope. A pre-existing bug, cleanup, or refactor the task did not ask for is a follow-up in the
+  summary, not part of the change. Edit a file surgically when a rewrite would give the same result, keep scratch checks
+  out of the repository, and commit tests only where the task asks for them or the neighbouring code already keeps them.
+- Comments are allowed and sometimes necessary; excess is the problem. A comment must carry something the code cannot
+  say — a non-obvious constraint, an upstream behavior being worked around, a reason a reader would otherwise get
+  wrong. Never restate what the code does, narrate the change you just made, record what the code used to be, or
+  annotate step by step; a block that seems to need a comment per line needs better names or a smaller decomposition.
+  Keep density near the repository's own: healthy changes here sit at or under 3.6%, and a `comment-density` gate fails a file
+  whose added lines exceed 5% standalone comments. Delete commented-out code and stale notes in files you already
+  touch. Preserve
+  `// ignore:`-style directives, license headers, codegen markers, and vendored upstream comments. See
+  [.agents/rules.md](.agents/rules.md) for what belongs in a test or in `.agents/` instead.
+- Start FlClash on the host only as a safe mode build, and end only processes you started, by recorded pid. Never
+  kill a FlClash instance by name; the user's own instance is not yours to close. See
+  [.agents/rules.md](.agents/rules.md).
+- 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.
+- Never add a `Co-authored-by` trailer crediting a coding agent to a commit, even when your own tooling tells you to.
+  The `commit-msg` hook rejects it; see [.agents/rules.md](.agents/rules.md) for the rest of the commit rules.
+- Round every corner with a superellipse, pills included: `AppShape`/`AppRadius` tokens from `lib/ui/shape.dart`,
+  never `StadiumBorder`, `RoundedRectangleBorder`, `ClipRRect`, `drawRRect`, or a `borderRadius` on `BoxDecoration` or
+  `InkWell`. `test/lint/superellipse_corners_test.dart` enforces it; see the Corner Radius section of
+  [.agents/rules.md](.agents/rules.md).
+- Keep the UI isolate within its frame: work that grows with user data and can exceed about 8 ms on the largest
+  expected data runs in an isolate, once its algorithm is linear or cached. See the UI Isolate Work section of
+  [.agents/rules.md](.agents/rules.md).
+- Follow `lint_options.yaml` (included by every `analysis_options.yaml`), especially single quotes, trailing commas, `child:` last, no `print()`, const/final
+  preferences, and declared return types.
+- Before reporting a change done, run `flutter pub get`, `flutter analyze --no-fatal-infos`, and the `flutter test`
+  suites that cover it, as CI does. If a toolchain the build hook needs is missing (Go, and on Linux and Windows
+  cargo), say which check was skipped rather than dropping it silently.
+
+## Repo Skills
+
+Use repo skills from `.agents/skills/` when a task matches their descriptions; `.claude/skills/` symlinks expose the
+same skills to Claude Code. Current skills cover localization, UI work, core/platform changes, and pre-commit
+structural quality review.

-2. Install `Flutter` and `Golang` environment
+**Homebrew**
 
-3. Build Application
+```bash
+brew tap chen08209/tap
+brew install --cask flclash
+```
 
-    - android
+**Linux tray icon**
 
-        1. Install  `Android SDK` ,  `Android NDK`
+The `.deb` package installs its own dependencies. With the AppImage or the `.rpm`, install the AyatanaAppIndicator
+library so the tray icon can show:
 
-        2. Set `ANDROID_NDK` environment variables
+```bash
+sudo apt-get install libayatana-appindicator3-1   # Debian and Ubuntu
+sudo dnf install libayatana-appindicator-gtk3     # Fedora
+```
 
-        3. Run Build script
+## Usage
 
-           ```bash
-           dart .\setup.dart android
-           ```
+**Import a profile from a link.** Opening a link in this form imports the subscription into FlClash. The `clashmeta://`
+and `flclash://` schemes work the same way.
 
-    - windows
+```text
+clash://install-config?url=<URL-encoded subscription link>
+```
 
-        1. You need a windows client
+**Automate on Android.** Tasker, MacroDroid and similar apps can start, stop or toggle the proxy by starting an
+activity with one of these actions:
 
-        2. Install  `Gcc`，`Inno Setup`
+```text
+com.follow.clash.action.START
+com.follow.clash.action.STOP
+com.follow.clash.action.TOGGLE
+```
 
-        3. Run build script
+From a computer, the same works over adb:
 
-           ```bash
-           dart .\setup.dart	
-           ```
+```bash
+adb shell am start -a com.follow.clash.action.TOGGLE
+```
 
-    - linux
+## Build from source
 
-        1. You need a linux client
+You need [Flutter](https://docs.flutter.dev/get-started/install) 3.47 (release builds use 3.47.6),
+[Go](https://go.dev/dl/) 1.27 and [Rust](https://rustup.rs/) installed through rustup. Each platform builds on its own
+host, except Android, which builds anywhere.
 
-        2. Run build script
+```bash
+git clone --recursive https://github.com/chen08209/FlClash.git
+cd FlClash
+flutter pub get
+dart setup.dart android   # or windows, macos, linux
+```
 
-           ```bash
-           dart .\setup.dart	
-           ```
+Packages land in `dist/`. The Go core and the Rust libraries are compiled as part of the Flutter build.
 
-    - macOS
+| Platform | Also needed |
+| --- | --- |
+| Android | Android SDK with the NDK. Add `--arch arm64` to build a single ABI. |
+| Windows | GCC (MinGW-w64) for the core and [Inno Setup](https://jrsoftware.org/isinfo.php) 6 for the installer. |
+| macOS | Xcode and Node.js. The script installs `appdmg` through npm. |
+| Linux | Debian or Ubuntu. The script installs the build packages with apt and downloads `appimagetool`. |
 
-        1. You need a macOS client
+Run `dart setup.dart --help` for the remaining options, such as `--targets` to build only some package formats.
 
-        2. Run build script
+## Support
 
-           ```bash
-           dart .\setup.dart	
-           ```

+```
 
-## Build
+**Android 自动化。** Tasker、MacroDroid 等应用可以用下面的 Action 启动 Activity，从而启动、停止或切换代理：
 
-1. 更新 submodules
-   ```bash
-   git submodule update --init --recursive
-   ```
+```text
+com.follow.clash.action.START
+com.follow.clash.action.STOP
+com.follow.clash.action.TOGGLE
+```
 
-2. 安装 `Flutter` 以及 `Golang` 环境
+在电脑上也可以通过 adb 触发：
 
-3. 构建应用
+```bash
+adb shell am start -a com.follow.clash.action.TOGGLE
+```
 
-    - android
+## 从源码构建
 
-        1. 安装  `Android SDK` ,  `Android NDK`
+需要 [Flutter](https://docs.flutter.dev/get-started/install) 3.47（正式版构建使用 3.47.6）、[Go](https://go.dev/dl/) 1.27，
+以及通过 rustup 安装的 [Rust](https://rustup.rs/)。桌面端需要在对应系统上构建，Android 在任意系统上都能构建。
 
-        2. 设置 `ANDROID_NDK` 环境变量
+```bash
+git clone --recursive https://github.com/chen08209/FlClash.git
+cd FlClash
+flutter pub get
+dart setup.dart android   # 或 windows、macos、linux
+```
 
-        3. 运行构建脚本
+安装包输出到 `dist/`。Go 内核和 Rust 库会在 Flutter 构建过程中一并编译。
 
-           ```bash
-           dart .\setup.dart android
-           ```
+| 平台 | 额外依赖 |
+| --- | --- |
+| Android | 带 NDK 的 Android SDK。加上 `--arch arm64` 可以只构建单个 ABI。 |
+| Windows | 编译内核用的 GCC（MinGW-w64），以及打包安装程序用的 [Inno Setup](https://jrsoftware.org/isinfo.php) 6。 |
+| macOS | Xcode 与 Node.js。脚本会通过 npm 安装 `appdmg`。 |
+| Linux | Debian 或 Ubuntu。脚本会用 apt 安装构建所需的软件包，并下载 `appimagetool`。 |
 
-    - windows
+其余选项可以运行 `dart setup.dart --help` 查看，例如用 `--targets` 只构建部分安装包格式。
 
-        1. 你需要一个windows客户端
+## 支持
 
-        2. 安装 `Gcc`，`Inno Setup`
+给仓库点一个 Star 是支持项目最简单的方式。问题讨论和更新通知请关注 [Telegram 频道](https://t.me/FlClash)，
