-## Project Overview
-
-AmneziaVPN is a cross-platform VPN client built with C++ and Qt Quick (QML) for
-Windows, macOS, Linux, Android and iOS. It has three kinds of servers, each
-with its own config model (`serverConfigUtils::ConfigType`):
-
-- **Self-hosted.** The admin connects the app to their own server over SSH; the
-  app installs protocols as Docker containers (AmneziaWG, WireGuard, OpenVPN,
-  XRay, IPsec and others) and generates client configs (`SelfHostedAdmin`).
-  Access is shared with other users as `vpn://` keys, which import without
-  server management rights (`SelfHostedUser`).
-- **Amnezia Premium and Free.** Configs come from the Amnezia gateway API. The
-  gateway passes the backend's config through; the client does not invent
-  server-side values.
-- **Native protocol configs.** Third-party configs imported as they are:
-  WireGuard and AmneziaWG `.conf`, OpenVPN `.ovpn`, XRay and Shadowsocks links
-  (`Native`). The app only connects with them; there is no server to manage.
-
-A change to shared code (protocol configs, import, connection) must keep
-working for all three.
-
-The desktop builds run a privileged service next to the GUI; the GUI talks to
-it over Qt Remote Objects. Android, iOS and the macOS App Store build
-(`MACOS_NE`) run the tunnel in the platform's VPN extension instead.
-
-## Repository Layout
-
-- `client/core/` — business logic with no UI: controllers, configurators
-  (client config generation per protocol), installers (server-side setup over
-  SSH), protocol and server config models, repositories (encrypted settings
-  storage).
-- `client/ui/controllers/` — `*UiController` classes exposed to QML. Thin
-  adapters over `core/`: they translate between QML and core types and hold no
-  business logic of their own.
-- `client/ui/models/` — list and property models for QML.
-- `client/ui/qml/` — the interface:
-  - `Pages2/` — screens, one file per page.
-  - `Components/` — composite pieces of screens.
-  - `Controls2/` — design system controls, named `<Name>Type.qml`; text styles
-    live in `Controls2/TextTypes/`.
-  - `Modules/Style/AmneziaStyle.qml` — design tokens (colours and the like).
-  - `Config/` — `GlobalConfig`, `Dialogs` and other singletons.
-- `client/platforms/`, `client/android/`, `client/ios/`, `client/macos/` —
-  platform code: VPN extensions, Kotlin, Swift, Objective-C++.
-- `client/daemon/`, `client/mozilla/`, `service/`, `ipc/` — the privileged
-  service and its IPC.
-- `client/server_scripts/` — the shell scripts and Dockerfiles run on the
-  user's server.
-- `client/translations/` — Qt `.ts` files.
-- `client/tests/` — Qt Test suites, run through `ctest`.
-- `recipes/` — Conan recipes for native dependencies (protocol libraries,
-  OpenSSL, libssh and others).
-- `deploy/` — build and installer scripts. `.github/workflows/` — CI.
-- `client/3rd/` — vendored third-party code. Do not edit it.
-
-## Essential Commands
-
-Run from the repository root.
-
-```bash
-deploy/build.sh -h                                     # build options
-deploy/build.sh                                        # build for the host platform
-deploy/build.sh -t android --aab                       # Android APK and AAB
-cmake -S . -B build -DCMAKE_PREFIX_PATH=<Qt>/<platform> -DAMNEZIA_BUILD_TESTS=ON
-cmake --build build --parallel
-ctest --test-dir build/client/tests --output-on-failure
-```
-
-Qt 6.10 or later and Conan are required; native dependencies are built by Conan
-from `recipes/` on the first configure.
-
-## Repository Rules
-
-These three come first. Each one has been asked for repeatedly.
-
-### 1. Clean, self-documenting code, no comments
-
-- Names and structure carry the meaning. Code must be readable without help.
-- No explanatory comments in code: no `//` notes in QML or C++, no doc blocks.
-- The one exception is a hack that looks wrong on purpose: a workaround for a
-  platform or Qt bug, an ordering that must not be "fixed". Then a short comment
-  next to it says why.
-- Explanations of a change go into the chat summary or the commit message, not
-  into the code.
-- Leave existing comments alone unless the change removes the code they
-  describe.
-
-### 2. Reusable code (DRY), without abstraction for its own sake
-
-- **QML.** Every reusable component lives in its own file. A piece of a page
-  goes into its own file in `Components/` even when it is used once, if that
-  keeps the page short and readable. No inline `component` definitions or
-  `Component` blocks inside pages. Before writing a new control, look in
-  `Controls2/` and `Components/` for one that already does the job, and extend
-  it if it almost does.
-- **C++.** Logic shared by several places is extracted once and reused:
-  duplicated parsing, validation or config building is a bug waiting to diverge.
-- **No fanaticism.** Do not create a base class, interface, helper or file
-  that only renames a single call, has one trivial user, or exists "for the
-  future". Decompose when it makes the code shorter, clearer or removes
-  duplication; otherwise keep it direct.
-
-### 3. Do not add what was not asked for
-
-- Implement exactly the request. No extra screens, buttons, settings,
-  refactors, renames, translations or "while I'm here" fixes.
-- Ideas, improvements and problems noticed along the way are reported to the
-  user as suggestions. Nothing is implemented without the user agreeing first.
-- When a request is ambiguous, ask instead of guessing big.
-- Keep the diff small. If a fix grows beyond the obvious change, say so and
-  explain why before making it.
-
-### Other rules
-
-- **Committing is the user's call.** Prepare the change and a commit message;
-  do not commit or push unless asked. Commit messages use a conventional prefix
-  with a scope (`fix(ui): …`, `feat(macos): …`, `chore: …`): a one-line
-  subject plus one or two short body lines saying what was wrong and what
-  changed. Pull requests target `dev`.
-- **Format C++ with `.clang-format`.** Format the lines you touch; do not
-  reformat files the change does not otherwise touch.
-- **Delete unused code** instead of keeping it "for later".
-- **Do not edit `client/3rd/`.** Fix vendored code through its upstream or a
-  Conan recipe.
-
-## UI And Design System
-
-- **Figma is the source of truth.** Screens follow the "Amnezia APP VPN" file;
-  components follow the "Amnezia DS Library". Where the two disagree, the app
-  screens win.
-- **Build UI from the design system controls** in `Controls2/`
-  (`ButtonType`, `ListItemType`, `TextFieldType`, `SheetType`,
-  `NavigationBarType` and the others) and the text types in
-  `Controls2/TextTypes/`. Do not style raw Qt Quick Controls on a page.
-- **No hex colours in QML.** Every colour is a semantic token from
-  `AmneziaStyle.color`. A colour the tokens do not have is added to
-  `AmneziaStyle` first, with the name the design system gives it.
-- **Icons come from Figma**, exported from the DS Library. Never draw an icon
-  by hand. Exports include page background rectangles — strip them and keep
-  the `0 0 24 24` viewBox.
-- **Restyling a component never redesigns a screen.** A design system update
-  changes components; screen layout and behaviour stay unless the user asks.
-- **No Qt5Compat.GraphicalEffects.** It overflows the interpreted JS stack on
-  iOS. Use `QtQuick.Effects` (`MultiEffect`), and create effects only while
-  they are visible: each instance is expensive to create.
-
-### QML pitfalls
-
-- A vertical `ListView` resets the delegate's `x`. Put insets on the
-  ListView's `leftMargin`/`rightMargin`, or on a child inside the delegate.
-- `lineHeightMode: Text.FixedHeight` puts all the extra leading below the text,
-  while Figma splits it evenly. The text types already compensate with
-  `halfLeading` padding; a new text type must do the same.
-- QML is loaded from `qml.qrc`, not compiled ahead of time: a QML error shows
-  up only at runtime. When moving QML between files, compare the `import`
-  lines — types registered from C++ under their own URIs fail only when the
-  page is opened.
-
-## Translations
-
-- Every user-visible string goes through `qsTr()` in QML or `tr()` in C++.
-- The `.ts` files contain only finished, non-empty translations: no
-  `vanished`, `obsolete` or `unfinished` entries, and every language holds the
-  same set of strings. `lrelease` must report `N finished and 0 unfinished` for
-  every file.
-- Refresh `.ts` files only when the task is about translations. `lupdate` run
-  through `qt6_add_translations` misses QML, so run it over an explicit file
-  list that skips `client/3rd` (from `client/translations`):
-
-  ```bash
-  find .. -path ../3rd -prune -o -path ../3rd-prebuilt -prune -o \
-    \( -name '*.qml' -o -name '*.cpp' -o -name '*.h' -o -name '*.mm' \) -print \
-    | sort > /tmp/src.lst
-  <Qt>/bin/lupdate @/tmp/src.lst -ts amneziavpn_*.ts
-  ```
-
-- `lupdate` output differs between macOS and Windows (keychain strings swap
-  places), so a large `.ts` diff after a refresh is often only that.
-- Technical terms stay in English in every language: protocol parameter names
-  and their descriptions (`Jc`, `S1`, `H1`…), config keys, transport and
-  algorithm names. Ordinary UI words are translated.
-- Renaming a QML file changes its translation context, so its strings have to
-  be carried over.
-
-## Which Check When
-
-- **Touched C++** — build the affected targets, and run `ctest` when the change
-  touches anything the tests cover (servers, imports, configs, settings,
-  split tunneling, XRay).
-- **Touched QML** — build, then open every page you changed. If the app cannot
-  be launched, at least load the changed files through the QML engine so that
-  syntax, imports and type errors surface, and say what was not checked.
-- **Touched a protocol config, import or connection path** — check self-hosted,
-  Premium/Free and native configs, and every platform that consumes the field
-  (desktop service, Android, iOS/macOS NE).
-- **Touched CMake, recipes or the app icon** — reconfigure from a clean build
-  directory as well: branding paths are CMake cache variables and keep stale
-  values in an existing build directory.
-- **Touched translations** — `lrelease` on every `.ts` file, see above.
-
-## Privacy
-
-- Never commit or repeat private keys, `vpn://` keys, server addresses,
-  passwords or tokens — including ones found in pasted configs, logs or test
-  output.
-- Logs must not contain secrets or full config bodies.
-- Local absolute paths (`/Users/...`, `C:\...`) do not belong in repository
-  files.
-
-## Verification Culture
-
-- Verify your own work before reporting it. "Should work" is not a result;
-  say exactly what was built, run or opened, and what was not.
-- Hypotheses are settled by an experiment, not by reasoning about the code.
-- After a wrong diagnosis, remove the code it produced.
