+# Admin panel: all routes and API contracts
+
+Documentation of every route in the built-in `telesrv` admin panel — the SPA
+page addresses and the API routes behind them. The panel server lives in
+`cmd/telesrv-admin`; routes are declared in `(*server).routes()`
+(`server.go:50`).
+
+The panel is a plain HTTP server: it serves the built frontend (`/`) and a
+JSON API under the `/api/` prefix. Every API path requires a session (cookie),
+and every mutating request additionally requires a CSRF token. Many routes also
+check an operator permission (`permission`).
+
+## How to use this document
+
+- For each GET endpoint, the **request parameters** (query) and a short **response** shape are listed.
+- For each POST endpoint under `/api/actions/*` and the verification decisions, the **request body** (JSON) is given. They all share common fields (see below) plus their own specific fields.
+- `int64` in JSON may be sent either as a number or as a string (e.g. `"user_id": "123"` or `"user_id": 123`) — the server accepts both (`flexInt64`). `flexUnix` accepts Unix seconds or a date in `2006-01-02` / RFC3339 form.
+- All mutating requests go to the Admin API. A command's response is either `{"status":..., "message":..., "command_id":...}` on success (HTTP 200) or `{"error":..., "code":...}` on error. An optimistic-locking conflict is `409`.
+
+## Authentication and session
+
+| Method | Path | Description |
+| --- | --- | --- |
+| POST | `/api/login` | Log in. Body: `{"secret": "..."}`. Validates the config secret, issues a signed session cookie and CSRF cookie. The only mutating route without a CSRF token (no session yet); only Origin is checked. |
+| POST | `/api/logout` | Log out. Destroys the session and CSRF cookie. |
+| GET | `/api/session` | Returns `{"actor": "...", "permissions": [...], "csrf_token": "..."}`. Called by the panel on startup. |
+
+The session lives in a signed cookie (default TTL 12 hours); there is no
+server-side session store. Every request except `GET/HEAD/OPTIONS` and
+`/api/login` must present:
+
+- the `telesrv_admin_csrf` cookie;
+- the `X-CSRF-Token` header with the same value;
+- an Origin matching the host (when Origin is present).
+
+Violating any of the three — `403 Forbidden`.
+
+## Permissions and their checks
+
+The panel distinguishes plain authorization (`requireAuthAPI`) from a
+permission check (`requirePermission`). Permission names match the strings in
+`TELESRV_ADMIN_UI_PERMISSIONS`:
+
+| Permission | What it grants |
+| --- | --- |
+| `*` | All permissions (wildcard). |
+| `premium.manage` | Managing the Premium plan catalog, granting Premium. |
+| `bots.token.read` | Exporting a bot token (`/api/actions/export-bot-token`). |
+| `verification.review` | Reading and deciding the official verification queue. |
+| `verification.revoke` | Stripping the official badge (in addition to `verification.review`). |
+| `botverification.review` | Reading and deciding the third-party (bot) verification queue. |
+| `botverification.manage` | Appointing verifiers, editing the icon catalog, stripping a third-party mark. |
+
+Official and third-party verification rights are intentionally independent. The
+session's permission list is returned from `/api/session` so the UI can hide
+unavailable sections.
+
+## Interface pages (SPA)
+
+SPA routes are declarative: any section name is served as `/` (index.html), and
+the frontend decides what to render (`web/src/pages/Routes.tsx`).
+
+| Path | Page |
+| --- | --- |
+| `/` | Dashboard (counters, storage stats, section links). |
+| `/accounts` | Account list (with search). |
+| `/accounts/{id}` | Account card: profile, actions. |
+| `/channels` | Supergroup and channel list. |
+| `/channels/{id}` | Channel card. |
+| `/bots` | Bot list. |
+| `/bots/{id}` | Bot card. |
+| `/broadcasts` | Broadcasts. |
+| `/monetization`, `/premium` | Stars and Premium: plans, grants. Requires `premium.manage`. |
+| `/moderation` | Complaints and moderation: case list. |
+| `/moderation/{id}` | Moderation case details. |
+| `/emoji` | Emoji set catalog. |
+| `/stickers` | Sticker pack catalog. |
+| `/gif-catalog` | GIF catalog. |
+| `/messages`, `/messages/private` | Private message audit. |
+| `/messages/detail`, `/messages/private/detail` | Private message detail (`?owner_user_id=&msg_id=`). |
+| `/messages/groups` | Group/channel message audit. |
+| `/messages/groups/detail` | Group message detail (`?channel_id=&msg_id=`). |
+| `/gifts` | Star gifts: catalog, collectibles, auctions. |
+| `/give-gifts` | Gift granting. |
+| `/collectible-usernames` | Collectible usernames. |
+| `/collectible-usernames/{id}` | Collectible username card. |
+| `/collectible-phones` | Anonymous numbers. |
+| `/account-ratings` | Account ratings. |
+| `/account-ratings/{user_id}` | Account rating card. |
+| `/storage` | Object storage: stats. |
+| `/verification` | Official verification: application queue. Requires `verification.review`. |
+| `/verification/{id}` | Official verification application details. Requires `verification.review`. |
+| `/bot-verification` | Third-party verification: verifiers, icons, marks, queue. Requires `botverification.review`. |
+| `/bot-verification/{id}` | Third-party verification request details. Requires `botverification.review`. |
+
+An unknown API path returns `404 {"error":"api route not found"}`; any unknown
+frontend path is served as `/`.
+
+## Response conventions
+
+- Successful reads — `200` + JSON; files (avatars, animations, previews) — the file itself.
+- Errors — JSON of the form `{"error": "...", "code": "..."}` with the corresponding HTTP status.
+- `401` — missing/expired session; `403` — CSRF/Origin violation or missing permission (in `requirePermission` the body gets an added `permission` field); `409` — optimistic-locking conflict (moderation case, verification); `502` — Admin API unreachable.
+- Errors from commands sent to the Admin API are returned as `{"status": ..., "message": ..., "error": ...}`.
+
+## Common command fields (POST `/api/actions/*`)
+
+Every mutating request carries in its body:
+
+| Field | Type | Description |
+| --- | --- | --- |
+| `command_id` | string | Idempotency key for the command. Repeating the same `command_id` does not execute the action twice. If empty — generated by the server. |
+| `reason` | string | Mandatory operation reason (audit). |
+| `confirm` | bool | Operator confirmation (`true`). |
+
+---

+# Админ-панель: все пути и контракты API
+
+Документация по всем путям встроенной админ-панели `telesrv` — адресам
+страниц (SPA) и API-маршрутам, которые за ними стоят. Сервер панели живёт в
+`cmd/telesrv-admin`, маршруты объявлены в функции `(*server).routes()`
+(`server.go:50`).
+
+Панель — это обычный HTTP-сервер: он отдаёт собранный фронтенд (`/`) и JSON-API
+под префиксом `/api/`. Все API-пути требуют сессию (cookie), а все
+изменяющие запросы — ещё и CSRF-токен. Многие маршруты дополнительно проверяют
+права оператора (`permission`).
+
+## Как пользоваться этим документом
+
+- Для каждого GET-эндпоинта указаны **параметры запроса** (query) и краткая
+  форма **ответа**.
+- Для каждого POST-эндпоинта в блоке `/api/actions/*` и решений верификации
+  указано **тело запроса** (JSON). Все они разделяют общие поля
+  (см. ниже) плюс свои специфичные поля.
+- `int64` в JSON можно передавать и как число, и как строку (например,
+  `"user_id": "123"` или `"user_id": 123`) — сервер принимает оба варианта
+  (`flexInt64`). `flexUnix` принимает Unix-секунды или дату `2006-01-02` /
+  RFC3339.
+- Все изменяющие запросы идут в Admin API. Ответ команды — либо
+  `{"status":..., "message":..., "command_id":...}` при успехе (HTTP 200), либо
+  `{"error":..., "code":...}` при ошибке. Конфликт оптимистичной блокировки —
+  `409`.
+
+## Аутентификация и сессия
+
+| Метод | Путь | Описание |
+| --- | --- | --- |
+| POST | `/api/login` | Вход. Тело: `{"secret": "..."}`. Проверяет секрет из конфига, выдаёт подписанную cookie-сессию и cookie CSRF. Единственный изменяющий маршрут без CSRF-токена; проверяется только Origin. |
+| POST | `/api/logout` | Выход. Уничтожает сессию и cookie CSRF. |
+| GET | `/api/session` | Возвращает `{"actor": "...", "permissions": [...], "csrf_token": "..."}`. Панель вызывает его при старте. |
+
+Сессия живёт в подписанной cookie (TTL по умолчанию 12 часов), серверного
+хранилища сессий нет. Все запросы, кроме `GET/HEAD/OPTIONS` и `/api/login`,
+обязаны предъявить:
+
+- cookie `telesrv_admin_csrf`;
+- заголовок `X-CSRF-Token` с тем же значением;
+- Origin, совпадающий с хостом (если Origin присутствует).
+
+Нарушение любого из трёх условий — `403 Forbidden`.
+
+## Права и их проверка
+
+Панель различает обычную авторизацию (`requireAuthAPI`) и проверку права
+(`requirePermission`). Имена прав совпадают со строками в
+`TELESRV_ADMIN_UI_PERMISSIONS`:
+
+| Право | Что даёт |
+| --- | --- |
+| `*` | Все права (wildcard). |
+| `premium.manage` | Управление каталогом Premium-планов, начисление Premium. |
+| `bots.token.read` | Экспорт токена бота (`/api/actions/export-bot-token`). |
+| `verification.review` | Чтение и решение очереди официальной верификации. |
+| `verification.revoke` | Снятие официального бейджа (в дополнение к `verification.review`). |
+| `botverification.review` | Чтение и решение очереди сторонней (ботовой) верификации. |
+| `botverification.manage` | Назначение верификаторов, редактирование каталога иконок, снятие метки сторонней верификации. |
+
+Права официальной и сторонней верификации намеренно независимы. Список прав
+сессии возвращается в `/api/session`, чтобы интерфейс скрывал недоступные
+разделы.
+
+## Страницы интерфейса (SPA)
+
+SPA-роуты декларативны: любое имя раздела отдаётся сервером как `/` (index.html),
+а сам фронтенд решает, что рендерить (`web/src/pages/Routes.tsx`).
+
+| Путь | Страница |
+| --- | --- |
+| `/` | Панель управления (счётчики, статистика хранилища, ссылки на разделы). |
+| `/accounts` | Список аккаунтов (с поиском). |
+| `/accounts/{id}` | Карточка аккаунта: профиль, действия. |
+| `/channels` | Список супергрупп и каналов. |
+| `/channels/{id}` | Карточка канала. |
+| `/bots` | Список ботов. |
+| `/bots/{id}` | Карточка бота. |
+| `/broadcasts` | Рассылки. |
+| `/monetization`, `/premium` | Звёзды и Premium: планы, начисление. Требует `premium.manage`. |
+| `/moderation` | Жалобы и модерация: список кейсов. |
+| `/moderation/{id}` | Детали кейса модерации. |
+| `/emoji` | Каталог emoji-наборов. |
+| `/stickers` | Каталог стикерпаков. |
+| `/gif-catalog` | Каталог GIF. |
+| `/messages`, `/messages/private` | Аудит личных сообщений. |
+| `/messages/detail`, `/messages/private/detail` | Детали личного сообщения (`?owner_user_id=&msg_id=`). |
+| `/messages/groups` | Аудит сообщений групп/каналов. |
+| `/messages/groups/detail` | Детали сообщения в группе (`?channel_id=&msg_id=`). |
+| `/gifts` | Звёздные подарки: каталог, коллекционки, аукционы. |
+| `/give-gifts` | Выдача подарков. |
+| `/collectible-usernames` | Коллекционные юзернеймы. |
+| `/collectible-usernames/{id}` | Карточка коллекционного юзернейма. |
+| `/collectible-phones` | Анонимные номера. |
+| `/account-ratings` | Рейтинг аккаунтов. |
+| `/account-ratings/{user_id}` | Карточка рейтинга аккаунта. |
+| `/storage` | Объектное хранилище: статистика. |
+| `/verification` | Официальная верификация: очередь заявок. Требует `verification.review`. |
+| `/verification/{id}` | Детали заявки на официальную верификацию. Требует `verification.review`. |
+| `/bot-verification` | Сторонняя верификация: верификаторы, иконки, метки, очередь. Требует `botverification.review`. |
+| `/bot-verification/{id}` | Детали запроса сторонней верификации. Требует `botverification.review`. |
+
+Несуществующий API-путь возвращает `404 {"error":"api route not found"}`; любой
+неизвестный путь фронтенда отдаётся как `/`.
+
+## Соглашения ответов
+
+- Успешные чтения — `200` + JSON; файлы (аватары, анимации, превью) — сам файл.
+- Ошибки — JSON вида `{"error": "...", "code": "..."}` с соответствующим HTTP-статусом.
+- `401` — нет/просрочена сессия; `403` — нарушение CSRF/Origin или не хватает права
+  (в `requirePermission` к телу добавляется поле `permission`);
+  `409` — конфликт оптимистичной блокировки (кейс модерации, верификация);
+  `502` — Admin API недоступен.
+- Ошибки команд, ушедших в Admin API, возвращаются как
+  `{"status": ..., "message": ..., "error": ...}`.
+
+## Общие поля команд (POST `/api/actions/*`)
+
+Каждый изменяющий запрос несёт в теле:
+
+| Поле | Тип | Описание |
+| --- | --- | --- |
+| `command_id` | string | Идемпотентный ключ команды. Повтор с тем же `command_id` не выполняет действие дважды. Если пусто — генерируется сервером. |
+| `reason` | string | Обязательная причина операции (аудит). |
+| `confirm` | bool | Подтверждение оператором (`true`). |

+# Local setup
+
+This guide shows the shortest safe path for running gramsrv on a development
+machine or a small test server.
+
+## 1. Prepare local configuration
+
+The repository intentionally tracks only `.env.example`. Your real `.env` is
+ignored by Git and must not be committed.
+
+Linux / macOS:
+
+```bash
+cp .env.example .env
+${EDITOR:-nano} .env
+```
+
+Windows PowerShell:
+
+```powershell
+Copy-Item .env.example .env
+notepad .env
+```
+
+If you prefer a different config filename, set `TELESRV_CONFIG` as a process
+environment variable before starting the server.
+
+## 2. Set the network values
+
+Review at least these values in `.env`:
+
+- `TELESRV_LISTEN` is the MTProto bind address. Use `0.0.0.0:2398` when
+  external clients must connect to this host, or `127.0.0.1:2398` for
+  same-machine testing only.
+- `TELESRV_ADVERTISE_IP` must be a client-reachable IPv4 or IPv6 address, not a
+  DNS name. Use `127.0.0.1` only when the patched client runs on the same
+  machine. Use a LAN or public IP for phones, other computers, or remote tests.
+- `TELESRV_PUBLIC_BASE_URL` and `TELESRV_PUBLIC_WEB_BASE_URL` are HTTP(S) URLs
+  used in generated public links. Put hostnames here, not in
+  `TELESRV_ADVERTISE_IP`.
+- `TELESRV_DEV_AUTH_CODE=12345` is convenient for local development but must not
+  be exposed as a production login code.
+
+## 3. Start Postgres and Redis
+
+The development compose file exposes Postgres on `127.0.0.1:5432` and Redis on
+`127.0.0.1:6399`, matching the defaults in `.env.example`.
+
+```bash
+docker compose -f deploy/docker-compose.yml up -d
+```
+
+If you use external Postgres or Redis, update `TELESRV_POSTGRES_DSN` and
+`TELESRV_REDIS_ADDR` in `.env`.
+
+## 4. Build and run the server
+
+Linux / macOS:
+
+```bash
+go build -o bin/gramsrv ./cmd/telesrv
+./bin/gramsrv
+```
+
+Windows PowerShell:
+
+```powershell
+go build -o bin/gramsrv.exe ./cmd/telesrv
+.\bin\gramsrv.exe
+```
+
+## 5. First-start checklist
+
+After startup, confirm:
+
+- migrations completed successfully;
+- `data/server_rsa.pem` was created if it did not already exist;
+- MTProto is listening on `TELESRV_LISTEN`;
+- Postgres and Redis connections are healthy;
+- patched clients use the matching DC address, port, and server RSA key.
+
+For the complete configuration reference, see
+[`docs/configuration.en.md`](configuration.en.md).

docs/update-service.md

+# Native client update service
+
+`cmd/telesrv-update` is a standalone HTTP service that provides two
+Telegram-compatible update surfaces:
+
+- `/current4` and `/files/*` for the built-in Telegram Desktop updater;
+- `/v1/resolve` for the main `telesrv` process to answer
+  `help.getAppUpdate` for Android, iOS, and other supported builds.
+
+The service has no HTTP upload endpoint. Operators publish a release by placing
+an immutable artifact in the configured `files` directory and atomically
+replacing `manifest.json`. The catalog validates the file size and SHA-256
+before exposing it, so truncated or accidentally replaced packages fail closed.
+
+## Quick start
+
+Create the working directories and start with the disabled example catalog:
+
+```powershell
+New-Item -ItemType Directory -Force data\updates\files
+Copy-Item deploy\update\manifest.example.json data\updates\manifest.json
+
+go run ./cmd/telesrv-update -check
+go run ./cmd/telesrv-update
+```
+
+Check the local endpoints:
+
+```powershell
+Invoke-RestMethod http://127.0.0.1:2402/readyz
+Invoke-RestMethod http://127.0.0.1:2402/current4
+```
+
+Connect the main server:
+
+```dotenv
+TELESRV_UPDATE_PUBLIC_URL=https://updates.example.test
+TELESRV_UPDATE_SERVICE_URL=http://127.0.0.1:2402
+TELESRV_UPDATE_REQUEST_TIMEOUT=2s
+```
+
+`PUBLIC_URL` must be reachable by clients and is advertised as
+`help.getConfig.autoupdate_url_prefix`. `SERVICE_URL` may remain a loopback or
+private route. When both routes are identical, `SERVICE_URL` may be omitted.
+Production deployments should place an HTTPS reverse proxy in front of the
+service without rewriting `/current4` or `/files/*`.
+
+Standalone service settings:
+
+```dotenv
+TELESRV_UPDATE_LISTEN=127.0.0.1:2402
+TELESRV_UPDATE_MANIFEST=data/updates/manifest.json
+TELESRV_UPDATE_FILES_DIR=data/updates/files
+```
+
+The manifest is reloaded automatically when its timestamp or size changes. A
+malformed replacement makes readiness and catalog requests return `503`; it is
+never combined with the previously validated snapshot. Validate a candidate
+before atomically replacing the active file:
+
+```powershell
+go run ./cmd/telesrv-update `
+  -manifest .\manifest.next.json `
+  -files .\data\updates\files `
+  -check
+```
+
+## Telegram Desktop contract
+
+TDesktop requests `<autoupdate_url_prefix>/current4`. A Windows x64 stable
+release is represented as:
+
+```json
+{
+  "win64": {
+    "stable": {
+      "released": 7000007,
+      "link": "/files/tx64upd7000007"
+    }
+  }
+}
+```
+
+The client compares `released` with its numeric `AppVersion`, downloads the
+artifact with HTTP Range support, verifies the embedded RSA signature, unpacks
+it, and only then exposes the normal update banner. A regular EXE or ZIP is not
+a valid update package.
+
+Build packages with TDesktop's `Packer` target. The equivalent Windows x64
+command is:
+
+```powershell
+Packer.exe `
+  -version 7000007 `
+  -path Telegram.exe `
+  -path Updater.exe `
+  -path "modules\x64\d3d\d3dcompiler_47.dll" `
+  -target win64
+```
+
+It produces `tx64upd7000007` and must report `Signature verified!` before the
+artifact is published.
+
+| Platform | `/current4` key | Typical package name |
+|---|---|---|
+| Windows x64 | `win64` | `tx64upd<build>` |
+| Windows ARM64 | `winarm` | `tarm64upd<build>` |
+| Windows x86 | `win` | `tupdate<build>` |
+| macOS Intel | `mac` | `tmacupd<build>` |
+| macOS Apple Silicon | `armac` | `tarmacupd<build>` |
+| Linux | `linux` | `tlinuxupd<build>` |
+
+## Update signing
+
+The public TDesktop sources contain Telegram's public update key; the matching
+private key is not published. A custom deployment must establish its own update
+signing identity:
+
+1. Generate a dedicated RSA-1024 key pair and keep the private key only in a
+   protected build secret store.
+2. Provide the private key to TDesktop's local `DesktopPrivate/packer_private.h`.
+3. Embed the matching public key in both the client update verifier and Packer.
+4. Rebuild the bootstrap client and Packer before publishing updates.
+5. Do not rotate the key without a transition client that trusts both identities.
+
+The update service never reads the private key and never creates signatures. It
+checks SHA-256 and serves an artifact that Packer has already signed. A stock
+TDesktop binary cannot install a package signed only by a custom key; the first
+custom client build must be distributed out of band.
+
+## HTTP behavior
+
+- `/healthz` reports process liveness.
+- `/readyz` validates the current catalog.
+- `/current`, `/current1` ... `/current4` return desktop metadata with
+  `Cache-Control: no-cache`.
+- `/files/<name>` serves only artifacts referenced by the current validated
+  catalog, supports GET/HEAD and Range, and emits an immutable cache policy and
+  a SHA-256-based ETag.
+- `/v1/resolve` returns a newer application release or `204 No Content`.
+
+Unknown package names are not exposed merely because a file exists in the
+directory. Published package names are immutable: changing an active file makes
+the endpoint return `503` until a matching manifest snapshot is loaded.
+
+## Android and iOS
+
+The main server forwards the client platform, current `app_version`, source,
+channel, and `lang_code` to `/v1/resolve`. The resolver selects localized notes,
+does not offer an equal or older version, and applies `url_by_source` when a
+matching installer/store source is configured.
+
+- A standalone Android build may open or install an APK URL, but the APK must be
+  signed with the same Android application signing key as the installed build.
+- Google Play and other store builds should use the corresponding store URL;
+  this mechanism does not bypass store policy.
+- iOS may display information returned by `help.getAppUpdate`, but installation
+  still happens through App Store, TestFlight, or MDM. A normal iOS application
+  cannot replace itself from an arbitrary IPA URL.
+- Set `can_not_skip` only after confirming that the target release is actually
+  available to every affected client.
+
+## Manifest fields
+
+- `desktop.<platform>.<channel>.build`: numeric TDesktop `AppVersion`.
+- `file`, `sha256`, `size`: immutable signed artifact and integrity metadata.
+- `apps.<platform>.<channel>.id`: stable positive release identifier.
+- `version`: value compared with the client's `initConnection.app_version`.
+- `notes`: localized text keyed by `en`, `ru`, `ru-ru`, and similar codes.
+- `url_by_source`: source-specific installer or store URL.
+- `can_not_skip`: whether the client may dismiss the application update.
+- `disabled`: keep a valid entry as a draft without publishing it.
+
+Supported channels are `stable`, `beta`, and `alpha`. See
+`deploy/update/manifest.example.json` for a complete disabled example.
