 Нужно передавать его как есть, без нормализации регистра и без URL-экранирования внутри JSON.

+# server esp pairing
+
+- краткое описание фичи:
+  - на сервере добавлен отдельный pairing-сценарий для подключения нового устройства через доверенную уже авторизованную сессию пользователя без выдачи приватных ключей сервером;
+  - добавлены `op`: `UpsertEspPairingSettings`, `StartEspPairing`, `ListEspPairingRequests`, `ApproveEspPairing`, `RejectEspPairing`, `GetEspPairingStatus`;
+  - подтверждать pairing может любая доверенная сессия пользователя.
+
+- что именно проверять:
+  - любая уже авторизованная сессия пользователя включает pairing и задаёт `passwordHash`;
+  - новое устройство создаёт заявку через `StartEspPairing`;
+  - другая доверенная сессия пользователя видит заявку в `ListEspPairingRequests`;
+  - доверенная сессия подтверждает заявку через `ApproveEspPairing`;
+  - новое устройство получает `approved + encryptedPayload` через `GetEspPairingStatus`;
+  - неавторизованное новое устройство не может вызывать управляющие pairing-операции.
+
+- ожидаемый результат:
+  - заявка создаётся со статусом `created`;
+  - у заявки есть `pairingId`, `shortCode`, `fingerprintB58`, `expiresAtMs`;
+  - после approve статус становится `approved`, а `encryptedPayload` возвращается новому устройству;
+  - неавторизованное соединение получает отказ `463 / PAIRING_REQUIRES_AUTH_SESSION`.
+
+- статус:
+  - `pending`

+# ESP Pairing и режимы подключения
+
+Этот документ фиксирует текущие и новые режимы входа/подключения в SHiNE без клиентской UI-реализации. Он нужен как отдельная точка входа по сценариям подключения, чтобы не смешивать обычную авторизацию и серверный pairing через доверенное уже авторизованное устройство пользователя.
+
+## 1. Текущие режимы
+
+### 1. Создание новой сессии через `deviceKey`
+
+Поток:
+
+`AuthChallenge -> CreateAuthSession`
+
+Смысл:
+
+- новое устройство уже владеет приватным `deviceKey`;
+- сервер проверяет подпись `deviceKey`;
+- создаётся обычная активная сессия пользователя;
+- этот поток остаётся без изменений.
+
+### 2. Повторный вход в существующую сессию через `sessionKey`
+
+Поток:
+
+`SessionChallenge -> SessionLogin`
+
+Смысл:
+
+- устройство уже владеет приватным `sessionKey`;
+- сервер проверяет подпись `sessionKey`;
+- соединение снова входит в существующую сессию;
+- этот поток тоже остаётся без изменений.
+
+## 2. Новый режим: добавление сессии через доверенное устройство пользователя
+
+Новый поток не заменяет обычный логин, а живёт рядом с ним.
+
+Цель:
+
+- новое устройство знает `login + pairing password`;
+- сервер использует пароль только как фильтр от мусора;
+- реальное доверие даёт любая уже онлайн доверенная сессия пользователя;
+- сервер не выдаёт приватные ключи сам от себя.
+
+Поток версии `v1`:
+
+1. Любая доверенная сессия пользователя создаёт на сервере pairing-настройку:
+   `UpsertEspPairingSettings`
+2. Новое устройство создаёт pending-заявку:
+   `StartEspPairing`
+3. Онлайн доверенная сессия видит список активных заявок:
+   `ListEspPairingRequests`
+4. Доверенная сессия либо подтверждает заявку:
+   `ApproveEspPairing`
+5. Либо отклоняет:
+   `RejectEspPairing`
+6. Новое устройство читает результат:
+   `GetEspPairingStatus`
+
+## 3. Что именно делает сервер
+
+- хранит включённость pairing и opaque `passwordHash`;
+- хранит pending/approved/rejected pairing-заявки;
+- рассчитывает короткий код `shortCode` из `7` цифр;
+- рассчитывает длинный `fingerprintB58` из `SHA-256` заявки;
+- уведомляет онлайн доверенные сессии событием `IncomingEspPairingRequest`, если такие сессии подключены;
+- хранит переданный `encryptedPayload` как непрозрачную строку и не анализирует его содержимое.
+
+## 4. Чего сервер в этой версии не делает
+
+- не передаёт приватный `deviceKey`;
+- не расшифровывает `encryptedPayload`;
+- не проверяет криптографию содержимого payload;
+- не делает клиентский UI;
+- не навязывает конкретную схему `Ed25519 -> X25519` в коде сервера.
+
+Это намеренно: серверная версия `v1` подготавливает безопасный каркас маршрутизации и состояния, а настоящая E2E-логика упаковки ключей будет жить на клиентах и ESP-устройствах.
+
+## 5. Роли и ограничения
+
+- любая уже авторизованная доверенная сессия пользователя может вызывать:
+  - `UpsertEspPairingSettings`
+  - `ListEspPairingRequests`
+  - `ApproveEspPairing`
+  - `RejectEspPairing`
+- новое устройство может вызвать `StartEspPairing` и `GetEspPairingStatus` без уже существующей авторизованной сессии;
+- `payloadType` поддерживается в вариантах:
+  - `1` — минимальный пакет
+  - `2` — расширенный пакет
+  - `3` — полный пакет
+
+Сервер не интерпретирует эти три типа глубже, а только фиксирует их в состоянии заявки.
+
+## 6. Статусы pairing-заявки
+
+- `created` — заявка создана и ждёт решения доверенной сессии;
+- `approved` — доверенная сессия подтвердила и приложила `encryptedPayload`;
+- `rejected` — доверенная сессия отклонила заявку;
+- `expired` — TTL заявки истёк до подтверждения.
+
+## 7. Практический смысл
+
+Эта схема даёт нужное разделение доверия:
+
+- пароль на сервере только отсеивает лишних;
+- онлайн доверенная сессия решает, добавлять ли новую сессию;
+- сервер остаётся маршрутизатором и хранилищем состояния, а не владельцем секретов.
