+# Контракт авторизации MoonWell через лаунчер
+
+Статус документа: обязательный контракт для Release-сборок.
+
+Ключевые слова **ДОЛЖЕН**, **НЕЛЬЗЯ**, **СЛЕДУЕТ** и **МОЖЕТ** описывают
+обязательность требований.
+
+## 1. Цель и границы доверия
+
+Игровой клиент World of Warcraft 3.3.5a остаётся стандартным SRP6-клиентом,
+но вместо постоянного пароля получает короткоживущий одноразовый ticket от
+MoonWell Launcher. Наличие или отсутствие полей логина в GlueXML не является
+границей безопасности. Решение о допустимости входа всегда принимает
+`authserver`.
+
+В поток входят четыре компонента:
+
+1. backend аутентифицирует пользователя и выпускает game ticket;
+2. launcher передаёт game account name и ticket только через environment block
+   нового `Wow.exe`;
+3. MoonWell.dll забирает значения до загрузки GlueXML и инициирует обычный SRP;
+4. `authserver` использует временные salt/verifier и атомарно погашает ticket
+   после успешного `CMD_AUTH_LOGON_PROOF`.
+
+## 2. Термины
+
+- **backend account** — учётная запись пользователя в сервисах MoonWell;
+- **game account** — имя учётной записи AzerothCore, передаваемое в поле `I`
+  `CMD_AUTH_LOGON_CHALLENGE`;
+- **launcher session** — аутентифицированная сессия launcher с backend;
+- **ticket** — одноразовый временный пароль для SRP;
+- **ticket generation** — уникальный внутренний идентификатор выпуска ticket,
+  используемый для отзыва и атомарного погашения;
+- **dev account** — явно разрешённая сервером учётная запись с постоянным SRP
+  verifier для локальной разработки.
+
+## 3. Формат launcher credentials
+
+Launcher передаёт ровно две обязательные переменные:
+
+```text
+MOONWELL_LAUNCH_ACCOUNT=<game account name>
+MOONWELL_LAUNCH_TICKET=<single-use SRP password>
+```
+
+### 3.1 `MOONWELL_LAUNCH_ACCOUNT`
+
+- непустая строка печатного ASCII (`0x21..0x7E`), без пробельных символов;
+- не содержит `NUL`, `=` и управляющих символов;
+- верхний предел безопасного чтения из environment — 320 байт;
+- перед SRP приводится к той же канонической форме, что и имя в AzerothCore,
+  то есть к ASCII uppercase;
+- backend и `authserver` сравнивают каноническое имя, а не display name.
+
+Ограничение 320 байт является только пределом входного буфера MoonWell.dll.
+Текущий протокол и этот репозиторий не поддерживают game account такой длины:
+`I_len` имеет размер `uint8`, `AuthSession.cpp` принимает challenge лишь с
+добавкой до 16 байт, а `AccountMgr` использует `MAX_ACCOUNT_STR = 17`.
+Поэтому backend **ДОЛЖЕН** отображать длинную backend account на отдельное
+короткое game account name, совместимое с текущим сервером (не более 17 байт).
+Расширение этого лимита является отдельным изменением протокола/сервера и не
+входит в настоящий контракт.
+
+### 3.2 `MOONWELL_LAUNCH_TICKET`
+
+- ровно 16 ASCII-символов;
+- допустимый алфавит: `A-Z` и `0-9`;
+- генерируется CSPRNG с равномерным rejection sampling;
+- энтропия полного пространства `36^16` — около 82,7 бит;
+- срок действия: не более 60 секунд от момента выпуска;
+- одноразовый;
+- новый выпуск атомарно отзывает предыдущий активный ticket game account.
+
+Ни один компонент **НЕ ДОЛЖЕН** нормализовать, менять регистр или обрезать
+ticket. Для SRP ticket используется в точности как получен.
+
+## 4. Контракт backend
+
+Конкретный HTTP route может определяться backend, но операция выпуска имеет
+следующую семантику:
+
+```json
+{
+  "launcher_session_id": "opaque launcher session identifier",
+  "client_build": 12340
+}
+```
+
+Успешный ответ:
+
+```json
+{
+  "account": "GAMEACCOUNT",
+  "ticket": "7Q9AV4R2M8ZK3W1P",
+  "expires_at": "2026-08-16T12:34:56Z"
+}
+```
+
+Требования к операции:
+
+- запрос разрешён только из действующей аутентифицированной launcher session;
+- требуемая пользователю MFA завершается до выпуска ticket;
+- backend проверяет право launcher session входить в указанный game account;
+- `client_build` должен входить в разрешённый список;
+- выпуск и отзыв предыдущей generation выполняются одной транзакцией;
+- ответ передаётся только по TLS и содержит `Cache-Control: no-store`;
+- ticket не возвращается повторно и не попадает в URL, telemetry, analytics,
+  tracing, audit payload, exception text или access log;
+- rate limit применяется как минимум к пользователю, game account, launcher
+  session и IP;
+- время жизни вычисляется по серверному времени. Часы клиента не являются
+  источником истины.
+
+Рекомендуемые машинные ошибки: `UNAUTHENTICATED`, `ACCOUNT_NOT_ALLOWED`,
+`CLIENT_BUILD_NOT_ALLOWED`, `RATE_LIMITED`, `GAME_ACCOUNT_NOT_COMPATIBLE` и
+`INTERNAL_ERROR`. Ошибка не должна содержать ticket или verifier.
+
+## 5. Хранение ticket
+
+Предпочтительный вариант — не хранить открытый ticket. Backend вычисляет
+временные SRP salt и verifier тем же кодом/алгоритмом, что
+`Acore::Crypto::SRP6::MakeRegistrationData(canonicalAccount, ticket)`, сохраняет
+их вместе с generation и уничтожает открытый ticket после формирования ответа.
+
+Минимальная логическая запись:
+
+```text
+account_id             UNIQUE
+generation_id          UNIQUE, unpredictable
+srp_salt               BINARY(32)
+srp_verifier           BINARY(32)
+launcher_session_hash  nullable/optional binding
+client_build           required binding
+issued_at               server timestamp
+expires_at              server timestamp, <= issued_at + 60 seconds
+consumed_at             nullable
+revoked_at              nullable
+```
+
+Активна только запись, для которой одновременно выполнено:
+
+```text
+consumed_at IS NULL
+AND revoked_at IS NULL
+AND expires_at > server_now
+```
+
+Если архитектура временно требует хранения открытого ticket, он должен быть
+зашифрован отдельным ротируемым ключом, недоступным read-only потребителям БД,
+и удалён при погашении/истечении. Хеш ticket сам по себе недостаточен для
+построения SRP verifier после выпуска.
+
+## 6. Запуск `Wow.exe`
+
+Launcher **ДОЛЖЕН**:
+
+1. получить ticket непосредственно перед запуском;
+2. построить отдельный Unicode environment block для дочернего процесса,
+   сохранив необходимые штатные переменные и добавив две MoonWell-переменные;
+3. вызвать `CreateProcessW` с `CREATE_UNICODE_ENVIRONMENT`;
+4. не добавлять credentials в command line;
+5. сразу после возврата `CreateProcessW` затереть все собственные изменяемые
+   буферы с ticket через гарантированно не оптимизируемую операцию, например
+   `SecureZeroMemory`;
+6. уничтожить созданный environment block независимо от результата запуска.
+
+Launcher **НЕ ДОЛЖЕН** менять собственное глобальное окружение через
+`SetEnvironmentVariable`, поскольку это создаёт окно утечки и гонки при
+параллельных запусках. Переменные должны существовать только в явно собранном
+environment block конкретного дочернего процесса.
+
+Ticket нельзя помещать в аргументы, файлы, реестр, crash metadata или логи.
+Дамп памяти процесса остаётся привилегированной атакой; MoonWell.dll должна
+минимизировать время жизни plaintext и очищать временные буферы.
+
+## 7. Контракт MoonWell.dll и GlueXML
+
+MoonWell.dll до загрузки GlueXML:
+
+1. читает обе launcher-переменные в ограниченные изменяемые буферы;
+2. немедленно удаляет их из окружения `Wow.exe`;
+3. валидирует обе переменные целиком;
+4. передаёт валидную пару GlueXML только в памяти процесса;
+5. очищает исходные и промежуточные буферы после начала SRP-входа.
+
+Пара считается валидной только если присутствуют и корректны обе переменные.
+Частичная, пустая, слишком длинная или синтаксически неверная пара полностью
+отбрасывается. Нельзя переходить к ручному логину из-за ошибки credentials в
+Release.
+
+Состояния интерфейса:
+
+| Сборка/вход | `AccountLoginUI` | Основное действие |
+| --- | --- | --- |
+| Release, валидная пара | скрыт | один вызов `DefaultServerLogin(account, ticket)` |
+| Release, пары нет/она невалидна | поля, password и save options скрыты | открыть launcher |
+| Debug и `MOONWELL_DEV_LOGIN=1` | прежняя форма видима | штатный ручной SRP-вход |
+| Debug без dev-флага | как Release | открыть launcher |
+
+При каждом не-dev запуске клиент удаляет ранее сохранённые account/password и
+отключает параметры их сохранения до отображения UI. Повторный автоматический
+вызов `DefaultServerLogin` в рамках одного процесса запрещён.
+
+`MOONWELL_DEV_LOGIN` читается и удаляется тем же ранним нативным кодом. Он
+учитывается только Debug-сборкой MoonWell.dll; Release-сборка всегда его
+игнорирует.
+
+## 8. Открытие launcher
+
+Кнопка «Авторизоваться»:
+
+1. ищет `MoonWellLauncher.exe` в каталоге фактически запущенного `Wow.exe`;
+2. если файл найден, запускает его без credentials;
+3. иначе открывает `moonwell://authorize?source=client` системным обработчиком.
+
+Путь нельзя брать из current working directory. Перед запуском следует
+проверять издателя Authenticode/ожидаемую подпись launcher.
+
+Установщик регистрирует URI scheme только для текущего пользователя в
+`HKCU\Software\Classes\moonwell`. Команда обработчика должна корректно заключать
+путь executable и аргумент URI в кавычки. Launcher рассматривает URI как
+недоверенный ввод, разрешает только известные host/action/query keys и никогда
+не принимает credentials через URI.
+
+## 9. Обязательный контракт `authserver`
+
+### 9.1 `CMD_AUTH_LOGON_CHALLENGE`
+
+После обычного разбора и канонизации game account сервер:
+
+1. загружает account, блокировки и режим авторизации;
+2. для обычного account ищет активную launcher ticket generation;
+3. проверяет expiry, `client_build` и дополнительные привязки;
+4. если активной generation нет, возвращает общий отказ до обращения к
+   постоянным account salt/verifier;
+5. сохраняет `generation_id` в объекте конкретной `AuthSession`;
+6. строит SRP challenge только из временных salt/verifier этой generation.
+
+Для launcher-only account SRP challenge не должен запрашивать интерактивный
+TOTP/security token: MFA является свойством launcher/backend-сессии и должна
+быть завершена до выпуска ticket. Иначе скрытый GlueXML не сможет закончить
+автоматический вход. Штатный AzerothCore TOTP может оставаться только в явно
+описанном dev-потоке с видимой формой.
+
+Для отсутствующего, истёкшего, отозванного или уже использованного ticket
+следует возвращать одинаковый протокольный результат, например
+`WOW_FAIL_UNKNOWN_ACCOUNT`, чтобы не создавать oracle состояния ticket.
+
+### 9.2 `CMD_AUTH_LOGON_PROOF`
+
+После успешной криптографической проверки proof, TOTP (если применяется) и
+версии клиента сервер **ДОЛЖЕН** в одной транзакции:
+
+1. выполнить условное погашение именно generation из текущей `AuthSession`:
+
+   ```sql
+   UPDATE launcher_ticket
+      SET consumed_at = CURRENT_TIMESTAMP(6)
+    WHERE account_id = ?
+      AND generation_id = ?
+      AND consumed_at IS NULL
+      AND revoked_at IS NULL
+      AND expires_at > CURRENT_TIMESTAMP(6);
+   ```
+
+2. убедиться, что изменена ровно одна строка;
+3. сохранить новую game session key и штатные login metadata;
+4. зафиксировать транзакцию;
+5. только после commit отправить клиенту успешный `AUTH_LOGON_PROOF`.
+
+Если условное погашение изменило ноль строк или commit не удался, сервер
+возвращает общий отказ и не создаёт авторизованную game session. Это обеспечивает
+отказ повторному proof даже если два challenge успели получить одну generation.
+
+Неуспешный proof не погашает ticket, но существующие механизмы rate limit и
+защиты от перебора продолжают действовать. Ticket всё равно истекает не позднее
+60 секунд после выпуска.
+
+### 9.3 Постоянный verifier и dev-доступ
+
+Для обычных accounts `authserver` никогда не выбирает и не проверяет постоянные
+`account.salt/account.verifier`. При миграции их следует сделать nullable и
+удалить у launcher-only accounts либо заменить отдельным режимом хранения,
+который невозможно случайно использовать в launcher-ветке.
+
+Ручной SRP разрешён только если серверная политика независимо подтверждает все
+условия:
+
+- account присутствует в явном dev allowlist;
+- account имеет режим `DEV_SRP`;
+- источник соответствует VPN/IP allowlist;
+- production-конфигурация не разрешает dev-режим по умолчанию.
+
+Клиентский Debug-флаг не передаётся authserver и не участвует в решении.
+
+### 9.4 Reconnect
+
+`CMD_AUTH_RECONNECT_*` может использовать session key только от ранее успешно
+погашенного ticket или разрешённого dev-входа. При включённом reconnect сервер
+должен хранить происхождение/время session key и отклонить legacy session keys,
+созданные до внедрения этой политики. Reconnect не оживляет ticket и не позволяет
+новому процессу выполнить новый logon без нового ticket.
+
+## 10. Состояния ticket и гонки
+
+Допустимые переходы:
+
+```text
+ISSUED -> CONSUMED
+ISSUED -> REVOKED       (выпущена новая generation)
+ISSUED -> EXPIRED       (server_now >= expires_at)
+```
+
+`CONSUMED`, `REVOKED` и `EXPIRED` — терминальные состояния. Cleanup может
+физически удалить терминальные записи позже, но не должен превращать их обратно
+в активные.
+
+Выдача новой generation не обязана завершать уже созданную игровую сессию, но
+обязана сделать proof старой незавершённой generation невозможным. Это
+обеспечивается сравнением `generation_id` при погашении.
+
+## 11. Логи и наблюдаемость
+
+Разрешено логировать только:
+
+- внутренний account id либо необратимо псевдонимизированный идентификатор;
+- generation id в хешированном/усечённом виде;
+- тип события: issued, rejected, consumed, revoked, expired;
+- код результата, build и тайминги без секретов.
+
+Запрещено логировать ticket, SRP verifier, environment block, полный launcher
+session token и HTTP response body. Фильтрация секретов должна применяться также
+к debug-логам, SQL tracing, crash reports и APM.
+
+## 12. Критерии приёмки
+
+Реализация считается соответствующей контракту, если автоматические или
+интеграционные тесты подтверждают:
+
+1. валидный свежий ticket даёт ровно один успешный вход;
+2. повторный proof и второй процесс с тем же ticket получают отказ;
+3. новый ticket отзывает предыдущий, включая уже полученный старый challenge;
+4. ticket старше 60 секунд отклоняется по серверному времени;
+5. прямой Release-запуск не показывает и не использует ручные credentials;
+6. одна отсутствующая/невалидная environment-переменная не запускает SRP;
+7. переменные удалены из окружения до GlueXML и отсутствуют в дочерних
+   процессах, созданных позже;
+8. Release игнорирует `MOONWELL_DEV_LOGIN=1`;
+9. Debug dev-login работает только для server-side allowlisted account и
+   разрешённого источника;
+10. обычный account с корректным старым постоянным паролем получает отказ;
+11. ticket, URL и command line отсутствуют во всех проверяемых логах;
+12. параллельные proof одной generation дают ровно один success;
+13. запрещённый client build и несоответствующая launcher-session binding дают
+    общий отказ без fallback на постоянный verifier;
+14. legacy session keys не позволяют обойти launcher-only политику reconnect.
+15. launcher-only challenge не требует интерактивного TOTP после запуска
+    `DefaultServerLogin`.
+
+## 13. Локальный запуск разработчика
+
+Поддерживаемая команда:
+
+```powershell
+.\run.ps1 -Env local -DeveloperLogin
+```
+
+Скрипт собирает Debug runtime, формирует отдельный environment block и добавляет
+`MOONWELL_DEV_LOGIN=1` только запускаемому процессу. Он не изменяет глобальное
+окружение пользователя и не делает server-side account dev-разрешённым.
+Debug DLL не включается в пользовательские Release-дистрибутивы.

+# Эксплуатация launcher-авторизации
+
+Нормативный протокол описан в
+[`LauncherAuthorizationContract.md`](LauncherAuthorizationContract.md). Этот
+документ относится к реализованной в данном репозитории серверной части.
+
+## Что входит в репозиторий
+
+- `authserver` использует временные SRP salt/verifier для всех обычных
+  аккаунтов и не делает fallback на постоянный пароль;
+- SQL update `2026_08_16_00.sql` добавляет активные ticket, журнал погашений,
+  точный IP allowlist для dev-аккаунтов и provenance session key;
+- `issue-launcher-ticket.sh` является reference adapter для backend и локальной
+  интеграции. Production backend должен реализовать ту же операцию внутри
+  своего доверенного процесса, включая аутентификацию launcher session и rate
+  limiting;
+- reconnect и вход в worldserver разрешены только session key с provenance
+  `launcher` или `dev`.
+
+Исходников MoonWell Launcher, MoonWell.dll, GlueXML и backend в этом
+репозитории нет. Их реализация должна следовать отдельным разделам контракта.
+
+## Выпуск ticket
+
+База должна быть запущена и обновлена штатным `ac-db-import`:
+
+```bash
+./issue-launcher-ticket.sh PLAYER --build 12340 --ttl 60
+```
+
+Успешный результат — одна JSON-строка в stdout. Она содержит plaintext ticket
+и должна быть сразу передана launcher по TLS с `Cache-Control: no-store`.
+Диагностика выводится в stderr. Новый вызов для того же account атомарно
+заменяет предыдущую активную generation.
+
+Скрипт не является публичным HTTP endpoint. Нельзя предоставлять игрокам
+доступ к его запуску или к MySQL credentials.
+
+## Dev allowlist
+
+Постоянный verifier используется только при совпадении account и точного
+remote IP с активной строкой allowlist:

+SET enabled = 0
+WHERE account_id = (SELECT id FROM account WHERE username = 'DEVACCOUNT')
+  AND allowed_ip = '10.20.30.40';
+```
+
+CIDR и wildcard намеренно не поддерживаются: allowlist требует точного IP.
+
+## Миграция и откат
+
+SQL update очищает существующие `account.session_key`, чтобы legacy reconnect
+не обходил launcher-only политику. После применения старые клиенты должны
+получить новый launcher ticket.
+
+Миграция безопасности намеренно не имеет автоматического fallback. Перед
+развёртыванием должны быть готовы backend issuer и Release-клиент. Для
+аварийного dev-доступа заранее добавьте только выделенный account и VPN IP в
+`launcher_dev_account`.
+
+## Проверка
+
+После сборки и применения update:
+
+1. выпустить ticket для тестового account;
+2. убедиться, что прямой вход со старым паролем отвергнут;
+3. войти с ticket;
+4. убедиться, что строка удалена из `launcher_ticket` и появилась в
+   `launcher_ticket_consumption`;
+5. повторить вход с тем же ticket и получить отказ;
+6. выпустить два ticket подряд и убедиться, что работает только второй.

+                       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other

+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among

+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING

+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>

+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.

+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+

+# AccountBound
+
+AccountBound is an AzerothCore module for WotLK 3.3.5a that shares selected
+collections and progression systems between eligible characters on the same
+game account.
+
+It combines achievements, mounts, companion pets, titles, reputations,
+professions and friends into one module with one configuration file. Every
+category can be enabled, disabled and filtered independently.
+
+## Features
+
+- Account-wide achievements with faction conversion support.
+- Account-wide mounts with riding, class and faction requirement checks.
+- Account-wide vanity companion pets.
+- Account-wide titles with faction conversion support.
+- Account-wide reputations that only copy higher standings.
+- Account-wide profession ranks, skill progress and recipes.
+- Configurable primary-profession limit up to all 11 WotLK professions.
+- Account-wide friend lists and friend notes.
+- Per-category startup backfill for existing realms.
+- Silent SQL synchronization without learned-spell or collection spam.
+- Character creation seeding before the character's first login.
+- Per-category ID allow lists and block lists.
+- One master switch and one module configuration file.
+- Uses AzerothCore's existing character tables.
+- No custom SQL tables are required.
+
+## Compatibility
+
+- AzerothCore WotLK 3.3.5a
+- AzerothCore `master`
+- `mod-playerbots/azerothcore-wotlk`
+- Built as a normal source module under `modules/`
+- Tested with a Release worldserver build on Windows
+
+The module uses hooks currently available in AzerothCore. Stock AzerothCore
+does not require a core patch.
+
+## Silent Database Synchronization
+
+AccountBound writes shared data directly to AzerothCore's existing character
+tables. It does not call `learnSpell()` or replay achievements, titles,
+reputation gains or friend notifications during login.
+
+The synchronization lifecycle is:
+
+1. `StartupBackfill` migrates characters that already exist before players can
+   log in.
+2. `SyncOnCreate` seeds a new character after its initial database save and
+   before its first login.
+3. Normal gameplay hooks persist newly earned data to the other characters on
+   the account.
+4. The target character loads the already-persisted rows during its next normal
+   login.
+
+This prevents login spam. If a requirement changes while a character is
+already online, such as gaining a higher riding rank, the newly eligible rows
+are stored immediately and become visible after one relog.
+
+## Installation
+
+Clone the repository into the AzerothCore modules directory:
+
+```bash
+cd azerothcore-wotlk/modules
+git clone https://github.com/AlsoNotMehh/AccountBound.git
+```
+
+Re-run CMake and rebuild `worldserver`.
+
+Copy:
+
+```text
+modules/AccountBound/conf/AccountBound.conf.dist
+```
+
+to:
+
+```text
+configs/modules/AccountBound.conf
+```
+
+Restart `worldserver`.
+
+The startup log should contain:
+
+```text
+Using modules configuration:
+> AccountBound.conf
+```
+
+## Quick Config
+
+The master switch controls the entire module:
+
+```ini
+AccountBound.Enable = 1
+```
+
+Each system has an independent switch:
+
+```ini
+AccountBound.Achievements.Enable = 1
+AccountBound.Mounts.Enable = 1
+AccountBound.Pets.Enable = 1
+AccountBound.Titles.Enable = 1
+AccountBound.Reputations.Enable = 1
+AccountBound.Professions.Enable = 1
+AccountBound.Friends.Enable = 1
+```
+
+Set any category to `0` to keep it character-specific.
+
+## Shared Data
+
+| Category | Shared data |
+| --- | --- |
+| Achievements | Completed achievements and completion date |
+| Mounts | Learned mount spells |
+| Pets | Vanity companion and minipet spells |
+| Titles | Known character titles |
+| Reputations | Highest eligible standing and reputation flags |
+| Professions | Ranks, current/max skill and learned recipes |
+| Friends | Friend list entries and notes |
+
+The module intentionally does not share quests, inventory, gold, currencies,
+honor, arena rating, instance lockouts, cooldowns, talents, glyphs, action bars,
+mail, auctions or hunter stable pets.
+
+Those systems contain character-specific progression, ownership or class data
+and should not be merged automatically.
+
+## ID Filters
+
+Achievements, mounts, pets, titles and reputations support:
+
+```ini
+AccountBound.CATEGORY.AllowList = all
+AccountBound.CATEGORY.BlockList = ""
+```
+
+Replace `CATEGORY` with:
+
+```text
+Achievements
+Mounts
+Pets
+Titles
+Reputations
+```
+
+`AllowList = all` permits every valid entry.
+
+`AllowList = none` permits no entries.
+
+A comma-separated allow list shares only those IDs:
+
+```ini
+AccountBound.Mounts.AllowList = 458,470,6648
+```
+
+The block list always wins:
+
+```ini
+AccountBound.Mounts.AllowList = all
+AccountBound.Mounts.BlockList = 48778,54729
+```
+
+Converted Horde or Alliance equivalents must also pass the configured filter.
+
+## Achievements
+
+Recommended defaults:
+
+```ini
+AccountBound.Achievements.Enable = 1
+AccountBound.Achievements.SyncOnCreate = 1
+AccountBound.Achievements.SyncRealmFirst = 0
+AccountBound.Achievements.SyncHidden = 0
+AccountBound.Achievements.ConvertFactionSpecific = 1
+```
+
+Realm First achievements are excluded by default because they represent a
+specific character or realm race.
+
+Faction-specific achievements are converted with AzerothCore's faction-change
+mapping when `ConvertFactionSpecific = 1`.
+
+Achievements are inserted into `character_achievement`. They are never replayed
+through the live achievement reward path, so the module does not resend
+announcements, mail, items or title notifications.
+
+## Mounts
+
+Recommended defaults:
+
+```ini
+AccountBound.Mounts.Enable = 1
+AccountBound.Mounts.SyncOnCreate = 1
+AccountBound.Mounts.RespectFactionRestrictions = 1
+AccountBound.Mounts.ConvertFactionSpecific = 1
+AccountBound.Mounts.RequireRiding = 1
+AccountBound.Mounts.RequireClass = 1
+```
+
+The module discovers mount spells from spell data and item templates.
+
+It can enforce:
+
+- Riding skill requirements.
+- Class restrictions for class mounts.
+- Horde and Alliance restrictions.
+- Same-faction restrictions for class mounts.
+
+Invalid shared mount rows can be cleaned at startup:
+
+```ini
+AccountBound.Mounts.CleanupInvalid = 1
+```
+
+## Companion Pets
+
+The pets category shares vanity companions only:
+
+```ini
+AccountBound.Pets.SyncOnCreate = 1
+AccountBound.Pets.IncludeCompanionSkillLine = 1
+AccountBound.Pets.IncludeMinipetSummons = 1
+```
+
+It detects WotLK companion skill-line spells and custom summons using
+`SUMMON_TYPE_MINIPET`.
+
+Hunter stable pets, permanent combat pets and pet talent data are not shared.
+
+## Titles
+
+Recommended defaults:
+
+```ini
+AccountBound.Titles.Enable = 1
+AccountBound.Titles.SyncOnCreate = 1
+AccountBound.Titles.SyncOnSave = 1
+AccountBound.Titles.SyncRealmFirst = 0
+AccountBound.Titles.ConvertFactionSpecific = 1
+```
+
+Realm First reward titles are excluded by default. Faction-specific titles are
+converted using AzerothCore's faction-change title mappings.
+
+## Reputations
+
+Recommended public-realm defaults:
+
+```ini
+AccountBound.Reputations.Enable = 1
+AccountBound.Reputations.SyncOnCreate = 1
+AccountBound.Reputations.SyncOnChange = 1
+AccountBound.Reputations.SameFactionOnly = 1
+AccountBound.Reputations.ConvertFactionSpecific = 1
+```
+
+Reputation sync is monotonic: it copies a standing only when it improves the
+target character. It never lowers another character's standing.
+
+Base reputation differences for race and class are respected. Cross-faction
+sharing can convert supported faction pairs.
+
+## Professions
+
+The default configuration allows all 11 WotLK primary professions:
+
+```ini
+AccountBound.Professions.MaxPrimaryProfessions = 11
+AccountBound.Professions.Primary.AllowList = all
+AccountBound.Professions.Primary.BlockList = ""
+```
+
+Accepted English profession names:
+
+```text
+alchemy, blacksmithing, enchanting, engineering, herbalism,
+inscription, jewelcrafting, leatherworking, mining, skinning, tailoring
+```
+
+Accepted Spanish aliases:
+
+```text
+alquimia, herreria, encantamiento, ingenieria, herboristeria,
+inscripcion, joyeria, peleteria, mineria, desuello, sastreria
+```
+
+Skill IDs are also accepted:
+
+```text
+171,164,333,202,182,773,755,165,186,393,197
+```
+
+Example:
+
+```ini
+AccountBound.Professions.Primary.AllowList = alchemy, enchanting, tailoring
+AccountBound.Professions.MaxPrimaryProfessions = 3
+```
+
+Strict allow-list enforcement is disabled by default:
+
+```ini
+AccountBound.Professions.Primary.EnforceAllowedList = 0
+```
+
+Warning: enabling it can remove blocked professions from existing characters.
+
+Account-wide profession settings:
+
+```ini
+AccountBound.Professions.SyncOnCreate = 1
+AccountBound.Professions.SyncSkillProgress = 1
+AccountBound.Professions.SyncProfessionRanks = 1
+AccountBound.Professions.SyncRecipes = 1
+AccountBound.Professions.SyncSkillGrantedSpells = 1
+AccountBound.Professions.IncludeSecondaryProfessions = 1
+AccountBound.Professions.RequireRecipeSkill = 1
+```
+
+Custom recipe spells can be explicitly allowed or blocked:
+
+```ini
+AccountBound.Professions.SpellAllowList = 900001,900002
+AccountBound.Professions.SpellBlockList = 20219,20222
+```
+
+## Friends
+
+The friends category mirrors the normal character friend list across every
+character on an account:
+
+```ini
+AccountBound.Friends.SyncOnCreate = 1
+AccountBound.Friends.SyncOnlineChanges = 1
+AccountBound.Friends.SyncIntervalSeconds = 3
+```
+
+Friend notes are shared. Characters belonging to the same account are removed
+from the friend list to avoid self-friend entries.
+
+Cross-faction friends are allowed by default:
+
+```ini
+AccountBound.Friends.SameFactionOnly = 0
+```
+
+## Startup Backfill
+
+Every progression category has a `StartupBackfill` setting.
+
+Example:
+
+```ini
+AccountBound.Achievements.StartupBackfill = 1
+AccountBound.Mounts.StartupBackfill = 1
+AccountBound.Pets.StartupBackfill = 1
+AccountBound.Titles.StartupBackfill = 1
+AccountBound.Reputations.StartupBackfill = 1
+AccountBound.Professions.StartupBackfill = 1
+AccountBound.Friends.StartupBackfill = 1
+```
+
+For an existing realm:
+
+1. Back up the characters database.
+2. Enable the categories you want.
+3. Enable their startup backfill options.
+4. Start `worldserver` once.
+5. Wait for every AccountBound startup message.
+6. Stop `worldserver`.
+7. Set the startup backfill options back to `0`.
+8. Start the server normally.
+
+Backfill uses idempotent inserts or monotonic updates, but it can touch many
+rows on a large realm.
+
+Version 1.1 replaces the old `SyncOnLogin` options with `SyncOnCreate`.
+Existing custom configuration files should be updated to use the new keys.
+
+## Safe Public-Realm Defaults
+
+```ini
+AccountBound.Enable = 1
+
+AccountBound.Achievements.SyncRealmFirst = 0
+AccountBound.Achievements.SyncHidden = 0
+
+AccountBound.Mounts.RespectFactionRestrictions = 1
+AccountBound.Mounts.RequireRiding = 1
+AccountBound.Mounts.RequireClass = 1
+
+AccountBound.Titles.SyncRealmFirst = 0
+
+AccountBound.Reputations.SameFactionOnly = 1
+AccountBound.Reputations.SyncUnpairedCrossFaction = 0
+
+AccountBound.Professions.Primary.EnforceAllowedList = 0
+AccountBound.Professions.RequireRecipeSkill = 1
+
+AccountBound.Friends.StartupBackfill = 1
+```
+
+After the initial migration, keep every broad `StartupBackfill` option disabled.
+
+## Database Tables Used
+
+The module uses normal AzerothCore tables:
+
+```text
+characters
+character_achievement
+character_spell
+character_skills
+character_reputation
+character_social
+```
+
+No custom tables or SQL installation files are required.
+
+## Troubleshooting
+
+If the module is not loaded:
+
+- Confirm the folder is `modules/AccountBound`.
+- Re-run CMake after adding the module.
+- Rebuild `worldserver`.
+- Confirm `configs/modules/AccountBound.conf` exists.
+- Confirm `AccountBound.Enable = 1`.
+
+If a mount is not shared:
+
+- Confirm the spell passes `AllowList` and `BlockList`.
+- Check riding, class and faction requirements.
+- Check `RequireRiding`, `RequireClass` and `RespectFactionRestrictions`.
+
+If a profession recipe is not shared:
+
+- Confirm the profession is allowed.
+- Confirm `SyncRecipes = 1`.
+- Confirm the target has sufficient skill when `RequireRecipeSkill = 1`.
+- Add custom recipes to `SpellAllowList`.
+
+If data was inserted while the target character was already online:
+
+- Relog once so AzerothCore reloads the updated character tables.
+
+If startup takes longer than normal:
+
+- Disable broad `StartupBackfill` options after the initial migration.
