+"""Anonymous install telemetry beacon (self-hosted friendly, opt-out).
+
+Once per ``TELEMETRY_INTERVAL_HOURS`` the worker sends a single obfuscation-free
+but fully anonymous "heartbeat" to a PostHog ingestion endpoint so the project
+maintainer can see how many installs are active and which versions/OSes are in
+use. No personal data, bot tokens, domains or user identities are sent — only
+an opaque per-install UUID plus coarse environment facts.
+
+Operators can opt out in three independent ways, any of which stops the beacon:
+  * ``TELEMETRY_ENABLED=false`` in ``.env``
+  * the *System → Anonymous install analytics* toggle in the web admin (stored
+    as a DB override and re-read every tick, so no restart is required)
+  * leaving ``TELEMETRY_ENDPOINT`` / ``TELEMETRY_API_KEY`` empty in the image
+
+Delivery is strictly fire-and-forget: every failure is swallowed so telemetry
+can never delay, block or crash the worker.

+# Анонимная телеметрия установок
+
+Чтобы понимать, сколько инсталляций активно и какие версии используются, бот может раз в сутки отправлять один **полностью обезличенный** «heartbeat». Телеметрия задумана как self-hosted friendly: её легко выключить, она не содержит персональных данных и не мешает работе бота.
+
+## Что отправляется
+
+Каждый сигнал — это случайный непривязанный идентификатор установки плюс грубые факты об окружении:
+
+| Поле | Пример | Назначение |
+| --- | --- | --- |
+| `installation_id` | `f47ac10b-...` (UUIDv4) | Случайный идентификатор установки. Генерируется один раз, хранится в БД. Не выводится из токена, домена или ID администраторов. |
+| `app_version` | `v3.4.6+gabc1234` | Полная версия сборки. |
+| `app_version_tag` | `v3.4.6` | Релизный тег для разбивки по версиям. |
+| `os` / `arch` | `linux` / `x86_64` | Платформа. |
+| `python_version` | `3.12.7` | Версия рантайма. |
+| `locale` | `ru` | Язык по умолчанию. |
+| `payment_providers` | `["stars", "yookassa"]` | Идентификаторы включённых платёжных провайдеров (без ключей и секретов). |
+| `users_bucket` | `51-200` | Число пользователей в виде **диапазона**, не точное значение. |
+| `webapp_enabled` / `panel_configured` | `true` | Флаги конфигурации. |
+
+Время приёма (`last_seen`) проставляет коллектор. «Активные установки» = уникальные `installation_id`, от которых сигнал приходил за последние ~48 часов; «разбивка по версиям» = последняя версия на каждую установку.
+
+## Чего там нет
+
+Никогда не отправляются: токен бота, домены, URL вебхуков, ключи платёжных систем и Remnawave, ID или данные пользователей, точное число пользователей, какой-либо контент.
+
+## Как выключить
+
+Достаточно любого из способов:
+
+- **`.env`**: `TELEMETRY_ENABLED=False`, затем перезапуск.
+- **Веб-админка**: `Admin → System → «Анонимная статистика установки»`. Переключатель применяется без перезапуска (читается из БД на каждом тике).
+- **Сборка/образ**: оставить пустыми `TELEMETRY_ENDPOINT` или `TELEMETRY_API_KEY` — без точки доставки беакон не запускается.
+
+## Доставка
+
+Беакон шлёт `POST {TELEMETRY_ENDPOINT}/capture/` в формате PostHog (`{api_key, event, distinct_id, properties}`). Доставка строго fire-and-forget: таймаут 10 секунд, любые ошибки проглатываются и логируются на уровне `debug` — телеметрия не может задержать или уронить воркер. При нескольких репликах воркера за интервал отправляет только одна (через Redis-lock).
+
+## Переменные окружения
+
+| Переменная | По умолчанию | Назначение |
+| --- | --- | --- |
+| `TELEMETRY_ENABLED` | `True` | Главный переключатель (opt-out). Дублируется тогглом в админке. |
+| `TELEMETRY_ENDPOINT` | `https://eu.i.posthog.com` | Хост приёма PostHog. Пусто — телеметрия выключена. |
+| `TELEMETRY_API_KEY` | пусто | Project API key PostHog (`phc_...`). Это write-only ключ ingest, его безопасно зашивать в образ. Пусто — телеметрия выключена. |
+| `TELEMETRY_INTERVAL_HOURS` | `24` | Интервал между сигналами. |

 В режиме без JSON-каталога наличие `TRAFFIC_PACKAGES` или `STARS_TRAFFIC_PACKAGES` переключает витрину на продажу трафика вместо подписок на срок.
 
+## Валюта каталога и ограничения провайдеров
+
+JSON-каталог поддерживает `default_currency`. По умолчанию используется `rub`, поэтому существующие каталоги с `prices_rub`, `rub`-пакетами и `.env`-ценами продолжают работать без изменений. Для другой валюты укажите код в нижнем регистре, например `usd`, `eur` или `usdt`, и задайте цены в generic-полях:
+
+- `prices`: `{ "usd": { "1": 4.99, "3": 12.99 } }`;
+- `traffic_packages`, `topup_packages`, `premium_topup_packages`, `hwid_device_packages`: ключ валюты вместо `rub`, например `{ "usd": [{ "gb": 50, "price": 2.5 }] }`;
+- `conversion_rate_per_gb`: курс конвертации оплаченной стоимости в GB для выбранной валюты.
+
+Legacy-поля остаются алиасами: `prices_rub`, `conversion_rate_rub_per_gb` и ключ `rub` автоматически попадают в generic-модель. Telegram Stars остаются отдельной валютой `stars`/`XTR` и не могут быть `default_currency`.
+
+Платежные провайдеры не принимают произвольный код валюты одинаково. Бот фильтрует способы оплаты и блокирует создание платежа, если текущая валюта каталога не поддерживается провайдером:
+
+| Провайдер | Валюты по умолчанию |
+| --- | --- |

+
