+
+Этот файл является единым источником правил для:
+- коммитов;
+- merge в `main`;
+- изменения версий в `VERSION.properties`;
+- `git push` из этого репозитория.
+
+## Язык
+
+- Пояснения к коммитам, PR и merge-запросам писать на русском языке.
+
+## Где хранится версия
+
+- Единый файл версий проекта: `VERSION.properties` в корне репозитория.
+- Основные поля:
+- `client.version` — версия клиентского UI.
+- `server.version` — версия серверной части.
+
+## Базовое правило для обычных коммитов
+
+- Перед каждым новым коммитом обязательно обновлять версии в `VERSION.properties`.
+- Если менялся только UI, увеличивать только `client.version`.
+- Если менялся только сервер, увеличивать только `server.version`.
+- Если менялись и UI, и сервер, увеличивать обе версии.
+- Для обычных коммитов вне `main` использовать стандартный patch-инкремент: `+1` к последнему числовому сегменту.
+- Пример: `1.2.346` → `1.2.347`.
+
+## Правило для `main`
+
+- Ветка `main` предназначена только для стабильных версий.
+- По умолчанию в `main` нужно не коммитить напрямую, а мержить готовые изменения из рабочей ветки.
+- Если пользователь просит сделать прямой коммит в `main`, нужно отдельно и явно предупредить, что это обход обычного стабильного процесса, и обязательно переспросить подтверждение.
+
+## Версионирование при merge или прямом коммите в `main`
+
+- Для попадания изменений в `main` действует отдельная схема инкремента.
+- Нужно увеличивать вторую цифру версии и обнулять третью.
+- Пример: `1.2.346` → `1.3.0`.
+- Если в наборе изменений менялся только UI, обновлять только `client.version`.
+- Если в наборе изменений менялся только сервер, обновлять только `server.version`.
+- Если соответствующая часть не менялась, её версию не трогать.
+
+## Правила для git commit и git push
+
+- Обычные коммиты делать стандартным `git commit`; токен для локального коммита не нужен и не используется.
+- Для операций `git push` при необходимости использовать токен из переменной окружения `$GITEA_TOKEN`.

-
-- SSH: `player@193.8.215.70`
-- Домен: `t.shineup.me`
-- IP: `193.8.215.70`
-- Назначение: второй production-контур SHiNE
-
-Структура:
-
-- каталог SHiNE: `/home/player/SHiNE`
-- сервер: `/home/player/SHiNE/shine-server/shine-server.jar`
-- UI: `/home/player/SHiNE/shine-ui`
-- данные: `/home/player/SHiNE/shine-server/data/`

-- `./gradlew deployUITest`
-
-Примечания:
-
-- этот хост резервный;

-
-## 3. Отдельный quad-devnet стенд `t1..t4`
-
-- VPS: `178.208.90.249`
-- пользователь: `player`
-- назначение: 4 независимых SHiNE-инстанса на Solana `devnet`
-
-Домены и логины:
-
-- `server_t1` -> `https://t1.shineup.me`
-- `server_t2` -> `https://t2.shineup.me`
-- `server_t3` -> `https://t3.shineup.me`
-- `server_t4` -> `https://t4.shineup.me`
-
-Каталоги:
-
-- `/home/player/t1/server`
-- `/home/player/t1/UI`
-- `/home/player/t2/server`
-- `/home/player/t2/UI`
-- `/home/player/t3/server`
-- `/home/player/t3/UI`
-- `/home/player/t4/server`
-- `/home/player/t4/UI`
-
-Подробная памятка на самом VPS:
-
-- `/home/player/Agents.md`
-
-Порты и systemd:
-
-- `t1` -> `7101` -> `shine-t1.service`
-- `t2` -> `7102` -> `shine-t2.service`
-- `t3` -> `7103` -> `shine-t3.service`
-- `t4` -> `7104` -> `shine-t4.service`
-
-Что важно по конфигу каждого инстанса:
-
-- отдельный `/home/player/tX/server/application.properties`
-- `server.port=710X`
-- `server.SHiNE.login=server_tX`
-- `db.path=data/shine.sqlite`
-- `solana.cluster=devnet`
-- `solana.rpcUrl=https://api.devnet.solana.com`
-- `server.ui.indexPath=/home/player/tX/UI/index.html`
-- `server.info.url=https://tX.shineup.me`
-
-UI каждого инстанса:
-
-- живёт в отдельной копии `shine-UI`;
-- использует свой `js/deploy-config.js`;
-- по умолчанию смотрит именно на свой `tX.shineup.me`.
-
-Caddy на стенде:
-
-- конфиг: `/etc/caddy/Caddyfile`
-- статика: `/home/player/tX/UI`
-- `/ws` проксируется на `127.0.0.1:710X`
-
-Operational-нюанс:
-
-- при одновременных рестартах возможны `HTTP 429` от `api.devnet.solana.com`;
-- поэтому сервисы `shine-t1..shine-t4` лучше перезапускать по одному, с паузой.
-
-## 4. Что проверять первым делом
-
-Для любого test-контура полезны такие быстрые проверки:
-
-```bash
-curl -I https://t.shineup.me
-curl -I https://test.shineup.me
-curl -I https://t1.shineup.me
-curl -I https://t2.shineup.me
-curl -I https://t3.shineup.me
-curl -I https://t4.shineup.me
-```
-
-Для quad-devnet VPS:
-
-```bash
-sudo systemctl --no-pager --full status caddy shine-t1 shine-t2 shine-t3 shine-t4
-```
-
-Для основного/резервного test:
-
-```bash
-sudo systemctl --no-pager --full status shine-server caddy
-```

-# Задание для Айдара: навести порядок в инструкциях агентов SHiNE
-
-## Кратко
-Нужно согласовать и оформить единый порядок инструкций для Codex/Telegram-агентов в проекте SHiNE, чтобы агенты стабильно понимали структуру проекта, границы ответственности и правила работы с сервером, UI, Solana-модулем, Telegram-ботом и игроками.
-
-## Зачем это нужно
-Сейчас проект состоит из нескольких связанных, но разных частей:
-
-- основной сервер `SHiNE-server/`;
-- UI `shine-UI/`;
-- Solana/Anchor-модуль `shine-solana/shine/`;
-- Telegram-агент-кодер `SHiNE-agent-bot-coder/`;
-- TURN-сервер;
-- документация `Dev_Docs/`;
-- отдельные рабочие папки игроков `Players/`.
-
-Без явных инструкций агент может путать эти зоны: например, смешать деплой Solana с деплоем сервера, изменить код от имени игрока, не обновить документацию API/DM/блокчейна или неправильно трактовать файл инструкций.
-
-## Что предлагается сделать
-1. Утвердить корневой `AGENTS.md` как главный набор правил проекта.
-2. Проверить и при необходимости уточнить локальный `AGENTS.md` внутри `shine-solana/shine/`.
-3. Оставить отдельные служебные инструкции Telegram-агента в `SHiNE-agent-bot-coder/AGENT.md`.
-4. Оставить автоматически читаемые инструкции Telegram-агента в `SHiNE-agent-bot-coder/AGENTS.md`.
-5. Явно закрепить режим игроков:
-   - игроки могут задавать вопросы, просить анализ, идеи и ТЗ;
-   - игроки не меняют код проекта напрямую;
-   - материалы игроков сохраняются только в `Players/<username>/`.
-6. Зафиксировать правило: если пользователь говорит «агент MD» или похожую формулировку, считать, что речь про автоматически читаемый `AGENTS.md`.
-7. Добавить простой процесс согласования изменений инструкций:
-   - Дима или другой участник готовит предложение;
-   - Айдар получает уведомление/заявку;
-   - Айдар отвечает: одобрить, отклонить или попросить доработать;
-   - только после одобрения агент вносит изменения в проектные инструкции.
-
-## Предлагаемая логика уведомления Айдару
-Минимальный вариант без сложной разработки:
-
-1. Агент готовит текст заявки.
-2. Текст отправляется Айдару в Telegram или в общий рабочий чат.
-3. В заявке явно указаны варианты ответа:
-   - `одобрить`;
-   - `отклонить`;
-   - `доработать: ...`.
-4. После ответа Айдара агент либо выполняет согласованные правки, либо фиксирует, что задача отклонена/нужна доработка.
-
-Более удобный вариант на будущее:
-
-- добавить в Telegram-бота команду или сценарий согласования задач, например:
-  - `/approve <id>`;
-  - `/reject <id> причина`;
-  - `/revise <id> комментарий`.
-
-Но для начала достаточно простого текстового согласования через Telegram.
-
-## Что нужно от Айдара
-Подтвердить, что такой порядок подходит:
-
-1. Корневой `AGENTS.md` остается главным правилом проекта.
-2. Для Solana, Telegram-агента и игроков сохраняются отдельные локальные правила.
-3. Игроки не меняют код напрямую, а готовят материалы и предложения.
-4. Изменения инструкций выполняются только после явного одобрения Айдара.
-5. Уведомления Айдару на первом этапе можно делать простым текстом в Telegram, без отдельной сложной системы заявок.
-
-## Ожидаемый результат
-После одобрения:
-
-- агенты будут стабильнее понимать границы проекта;
-- снизится риск случайных изменений не в той части системы;
-- появится понятный порядок согласования задач от игроков;
-- Айдар будет явно контролировать изменения в инструкциях и правилах работы агентов.

-# AGENT.md для SHiNE-agent-bot-coder
-
-Ты запущен как обработчик входящего Telegram-сообщения от пользователя.
-
-## Контекст
-- `SHiNE-agent-bot-coder` — локальный Telegram-бот-сервис агента-кодера для работы с этим проектом.
-- Сервис принимает входящие сообщения от пользователя Telegram, сохраняет историю, ставит задачи в очередь и последовательно запускает Codex CLI в рабочем проекте.
-- Текстовые сообщения обрабатываются напрямую, voice/audio сначала распознаются через OpenAI transcription, затем передаются как текстовая задача.
-- История диалога хранится в JSONL-файле, путь передаётся в промпте.
-- Сообщение может быть текстом или результатом распознавания голосового.
-- Ответ пойдёт пользователю в Telegram как обычное текстовое сообщение.
-- Единственная рабочая реализация сервиса — Python-скрипт `py_bot_service.py`; старая Java-реализация удалена как нерабочая и не должна восстанавливаться без отдельного решения Айдара.
-- В репозитории также есть отдельный Solana/Anchor-модуль `shine-solana/shine/`; он логически связан с SHiNE, но не должен автоматически подключаться к основному серверному deploy без отдельной команды.
-- Перед изменениями внутри `shine-solana/shine/` читать локальные инструкции `shine-solana/shine/AGENTS.md`; в git не добавлять локальные ключи, `.git`, `.idea`, `.gradle`, `target`, `node_modules`, `test-ledger`, логи, временные run-отчёты и `.env`-конфиги.
-
-## Авторитет команд и история
-- Основной пользователь и источник команд — Айдар: `@AidarKC` / `@aidarkc`.
-- Дополнительно разрешены игроки из whitelist (`ALLOWED_TELEGRAM_PLAYERS`), каждый со своей отдельной историей и рабочей папкой `Players/<username>/`.
-- Игроки работают в режиме вопросов/анализа/подготовки материалов: в промпте явно задано правило не менять код проекта и писать материалы только в своей папке.
-- Для неизвестных пользователей в личном чате сервис отвечает вежливым отказом.
-- В Telegram-канале/группе `@shine_writing` сервис выполняет сообщения только от Айдара, а ответы отправляет в тот же чат.
-- Если Telegram сообщает о миграции обычной группы в supergroup, сервис должен запомнить новый `chat_id` и отправлять ответы уже туда.
-- На события подключения/отключения пользователей (join/leave) сервис не отвечает и ничего не отправляет.
-
-## Очередь и состояние
-- Входящие задачи записываются в файловую очередь и обрабатываются строго по одной, чтобы не смешивать изменения в проекте.
-- Сервис ведёт состояние активной задачи и текущего файла истории, а после рестарта продолжает незавершённую обработку с учётом сохранённого состояния.
-- Истории диалогов хранятся в JSONL по каждому разрешённому username отдельно: `data/history/<username>/`.
-- Архив истории после `/new`: `data/history/<username>/archive/`.
-- После `/new` для этого же пользователя должен сбрасываться и контекст продолжения Codex-сессии; следующий запрос запускается как новая сессия, не через resume.
-- Для просмотра истории игрока открывать файлы в его папке истории по username.
-- Дедупликация входящих Telegram update нужна, чтобы одно сообщение не попало в обработку повторно.
-- Если Codex молчит во время активной задачи 2 минуты подряд, сервис отправляет аварийный статус с общим временем работы задачи; при дальнейшем молчании повторяет статус каждые 2 минуты.
-- После успешной обработки задачи из личного чата Айдара сервис должен отправить публичный итоговый отчёт в группу `@shine_writing`: первым сообщением исходный запрос, вторым сообщением-ответом итоговый ответ Codex. Промежуточные статусы в группу не дублировать.
-- Для приватных voice/audio-запросов в публичном отчёте первым сообщением отправлять исходный Telegram voice/audio-файл с подписью, где указан распознанный текст. В пользовательском тексте отчёта не показывать Telegram `file_id`.
-- Озвучивание финальных ответов настраивается персонально для каждого Telegram-пользователя командами `/voice_on`, `/voice_off`; для новых пользователей оно включено по умолчанию.
-- Адаптация текста перед озвучкой настраивается персонально командами `/voice_rewrite_on`, `/voice_rewrite_off`. Если она включена, сервис перед TTS вызывает дешёвую текстовую модель OpenAI и делает голосовую версию без длинных хэшей, путей, команд и технического шума, сохраняя смысл и порядок исходного ответа.
-- Режим личных ответов настраивается персонально командами `/single_message_on`, `/single_message_off`: либо одно редактируемое сообщение по этапам, либо отдельные сообщения как раньше.
-- Команда `/settings` должна сразу показывать текущее состояние всех персональных настроек пользователя и список команд для их изменения.
-- Если озвучивание включено, после полного текстового финального ответа сервис дополнительно отправляет voice-файл с синтезированной речью через OpenAI TTS даже для текстовых запросов. Voice отправляется в исходный чат, а также в известный личный чат пользователя и в общий чат `@shine_writing`, если они отличаются и доступны. Промежуточные статусы не озвучивать.
-- Команда `/status` должна показывать состояние очереди и персональные настройки: voice-ответы, адаптацию текста перед озвучкой и режим одного сообщения в личке.
-
-## Правила голосовой версии ответа
-- Текстовый финальный ответ должен оставаться полноценным: в нём можно указывать команды, пути, хэши коммитов, номера версий, результаты проверок и другие технические детали.
-- Голосовую версию финального ответа нужно делать короче и проще для восприятия на слух. Основной механизм — персонально включаемая адаптация текста через дополнительный OpenAI-вызов перед TTS.
-- В голосовой версии не зачитывать длинные хэши коммитов, токены, file_id, длинные команды, полные пути и другие строки, которые человек всё равно не сможет надёжно запомнить на слух.
-- Для commit/push в голосовой версии достаточно сказать краткий итог: что коммит сделан, что именно изменено, проверки прошли без ошибок, push выполнен, рабочее дерево чистое.
-- Если пользователю нужны точные команды, хэши или подробности, они должны оставаться в текстовом ответе.
-
-## Планы и отложенные фичи
-- Планы проекта по отложенным фичам хранятся в `TODO/`.
-- Внутри есть три горизонта:
-  - `near/` - ближайшие планы, обычно сегодня/завтра;
-  - `medium/` - среднесрочные планы, обычно недели или 1-2 месяца;
-  - `far/` - дальнее будущее без понятного срока.
-- Если пользователь спрашивает, какие есть планы или что можно продолжить, нужно смотреть эти три папки и отвечать кратким списком по горизонтам.
-- Файлы из `TODO/` не начинать реализовывать без явной команды пользователя.
-- После реализации фичи, требующей ручной проверки, нужно добавить отдельный файл в `Dev_Docs/Pending_Features/`.
-
-## Центр задач и предложений
-- Сервис хранит простые задачи и предложения в `data/task_center/items.json`.
-- Айдар может смотреть список через `/tasks` или естественные фразы вроде «покажи мои задачи», «покажи задачи Миланы».
-- Айдар может ставить задачи игрокам фразой вида «поставь задачу Милане: ...».
-- Игроки могут отправлять предложения Айдару фразой вида `предложение: ...`, `идея: ...` или `заявка: ...`.
-- Статусы меняются фразами с ID: `одобрить TC-0001`, `отклонить TC-0001`, `доработать TC-0001`, `закрыть TC-0001`.
-- После финального ответа в личном чате сервис добавляет короткое напоминание, если у пользователя есть активные задачи или предложения.
-
-## Локальный запуск и systemd
-- Основной запуск сервиса выполняется Python-скриптом `py_bot_service.py` из папки `SHiNE-agent-bot-coder/`.
-- Локальные секреты и параметры должны храниться в `.env`, этот файл не коммитится.
-- Для проверки Codex без Telegram можно использовать self-test режим сервиса.
-- Для постоянного локального запуска используется user-level systemd service `shine-agent-bot-coder`; скрипты установки лежат в `SHiNE-agent-bot-coder/scripts/systemd/`.
-- Если меняется логика сервиса, после изменений нужно проверить запуск локально и при необходимости перезапустить user systemd service.
-- Команда Telegram `/restart` (`/restart_service`) доступна только Айдару и выполняет отложенный рестарт после текущей задачи, до взятия следующей. Аварийный жёсткий рестарт доступен только Айдару командами `/restart_hard`, `/restart_now`, `/restart_force`.
-
-## Правила ответа
-- Пиши содержательно и коротко.
-- Не упоминай внутренние служебные детали, файловую систему и технические логи.
-- Если запрос требует действий с кодом/проектом, выполняй их в рабочей директории.
-- Если для ответа данных недостаточно, задай ровно один уточняющий вопрос.
-- Если была ошибка предыдущего запуска, в промпте будет пометка retry — учти это и продолжи с учётом текущего состояния проекта.

-## Назначение
-- Это автоматически читаемые инструкции Codex для папки `SHiNE-agent-bot-coder/`.
-- `SHiNE-agent-bot-coder` — локальный Telegram-бот-сервис агента-кодера для работы с проектом SHiNE.
-- Если пользователь говорит «агент MD», «агент с MD» или похожим образом про файл инструкций Codex, считать, что имеется в виду `AGENTS.md`.
-
-## Связанные инструкции
-- Подробные служебные правила Telegram-обработчика лежат в `AGENT.md`.
-- `AGENT.md` используется самим сервисом как файл инструкций, который передаётся в промпт обработчика входящих Telegram-сообщений.
-- При изменении логики сервиса сначала читать `AGENT.md`, затем код `py_bot_service.py`.
-
-## Планы и задачи
-- Отложенные задачи проекта лежат в `../TODO/`.
-- Точка входа по планам: `../TODO/README.md`.
-- Горизонты планов:
-  - `near/` - ближайшие планы;
-  - `medium/` - среднесрочные планы;
-  - `far/` - дальнее будущее.
-- Если пользователь спрашивает, какие есть планы или что можно продолжить, кратко перечислять задачи по этим горизонтам.
-- Не начинать реализацию задач из `TODO` без явной команды пользователя.
-
-## Проверка после изменений
-- Если меняется логика Telegram-бота, проверить локальный запуск или self-test, когда это уместно.
-- Если меняется только документация или инструкции, достаточно проверить, что ссылки на документы актуальны.

-   - `python3 SHiNE-agent-bot-coder/py_bot_service.py`
-
-## Быстрый self-test Codex (без Telegram)
-```bash
-python3 SHiNE-agent-bot-coder/py_bot_service.py --selftest-codex "Ответь одной строкой: Codex работает"
-```
-
-## Длинные voice/audio
-- Если аудио короткое, бот отправляет его в OpenAI как раньше.
-- Если аудио большое или длинное, бот локально пережимает его через `ffmpeg`, при необходимости режет на куски и распознаёт последовательно.
-- Если Telegram заранее сообщает большой размер файла, бот больше не отказывается сразу: сначала явно пишет, что пробует скачать файл, затем отдельно сообщает, удалось ли скачивание, и только после успешной загрузки переходит к подготовке аудио и OpenAI.
-- Для очень больших файлов упираемся не только в OpenAI, но и в лимит обычного облачного Telegram Bot API на скачивание файла ботом. Для таких случаев нужно использовать локальный `telegram-bot-api` сервер и указать его через `TELEGRAM_API_BASE_URL`.
-
-## Статусы в личке
-- Для `private`-чата бот поддерживает персональную настройку режима ответа.
-- По умолчанию он старается не засорять переписку промежуточными сообщениями: создаёт одно статусное сообщение и редактирует его по этапам.
-- Если включить `/single_message_off`, бот возвращается к старому режиму и отправляет отдельные сообщения по этапам и финальный ответ отдельно.
-- Если финальный текст в режиме одного сообщения не помещается целиком, бот оставляет первую часть в отредактированном статусном сообщении и отправляет максимум ещё одно дополнительное текстовое сообщение с хвостом ответа.
-- Голосовой ответ, если он включён, всегда приходит отдельным новым сообщением.
-
-## Запуск как systemd-сервис
-Файлы для установки:
-- `scripts/systemd/shine-agent-bot-coder.service`
-- `scripts/systemd/install-local-systemd.sh`
-
-Установка:
-- `bash SHiNE-agent-bot-coder/scripts/systemd/install-local-systemd.sh`
-
-Проверка:
-- `systemctl --user status shine-agent-bot-coder --no-pager`
-- `journalctl --user -u shine-agent-bot-coder -f`
-
-Перезапуск после изменений:
-- `systemctl --user restart shine-agent-bot-coder`
-
-## Telegram-команды
-- `/status` — активная задача и размер очереди.
-- `/settings` — текущие пользовательские настройки и команды для их изменения.
-- `/queue` — список задач в очереди.
-- `/stop` — остановить текущую задачу.
-- `/cancel <id|all>` — удалить задачу по id/префиксу или очистить очередь.
-- `/new` — архивировать текущую историю, сбросить продолжение Codex-сессии для этого пользователя и начать новый диалог.
-- `/voice_on` — включить озвучивание финальных ответов для текущего пользователя.
-- `/voice_off` — выключить озвучивание финальных ответов для текущего пользователя.
-- `/voice_rewrite_on` — включить адаптацию текста перед озвучкой.
-- `/voice_rewrite_off` — выключить адаптацию текста перед озвучкой.
-- `/single_message_on` — вести ответ в личке через одно редактируемое сообщение.
-- `/single_message_off` — слать отдельные сообщения по этапам и отдельный финальный ответ.
-- `/restart` или `/restart_service` — отложенный рестарт после текущей задачи, до взятия следующей (только для Айдара).
-- `/restart_hard` — жёсткий рестарт прямо сейчас (только для Айдара).

-/**
- * DatabaseTriggersInstaller — устанавливает триггеры, которые поддерживают бизнес-логику БД.
- *
- * Мы специально сделали триггеры максимально "совместимыми":
- *  - НЕТ динамических сообщений в RAISE(...): только фиксированные строки.
- *    (Некоторые SQLite-сборки / просмотрщики падают на "||" внутри RAISE.)
- *  - НЕТ UPSERT "ON CONFLICT DO UPDATE" — вместо него:
- *      INSERT OR IGNORE + UPDATE
- *    (Старые SQLite не знают UPSERT.)
- *
- * =============================================================================
- * ОПИСАНИЕ ТРИГГЕРОВ
- * =============================================================================
- *
- * [1] trg_blocks_line_integrity_bi  (BEFORE INSERT ON blocks)
- *     Контроль целостности "линий" (line_code / prev_line_number / prev_line_hash / this_line_number).
- *
- *     Зачем это нужно:
- *       - В каналах/ветках/действиях ты хочешь иметь "линейную" последовательность,
- *         где каждый следующий блок явно ссылается на предыдущий блок линии
- *         и подтверждает, что ссылка не подменена.
- *
- *     Когда срабатывает:
- *       - ТОЛЬКО если при вставке передано ХОТЯ БЫ ОДНО из line-полей.
- *       - Если line-поля не переданы — триггер вообще не работает (это важно).
- *
- *     Что проверяет:
- *       A) line-поля допускаются только для msg_type:
- *          0 (TECH), 1 (TEXT), 3 (CONNECTION), 4 (USER_PARAM)
- *       B) Если пришло хоть одно line-поле — обязаны прийти ВСЕ 4 (никаких "частичных")
- *       C) prev-блок линии существует в той же цепочке bch_name
- *       D) prev_hash совпадает с block_hash найденного prev-блока
- *       E) line_code корректный:
- *          - либо первый шаг после root: prev_line_number == line_code
- *          - либо prev уже принадлежит этой линии: p.line_code == NEW.line_code
- *       F) this_line_number:
- *          - первый шаг после root:
- *              TEXT: this_line_number = 0
- *              TECH/CONNECTION/USER_PARAM: this_line_number = 1
- *          - обычный шаг:
- *              TEXT: допускаем same или +1 (чтобы "edit" мог не двигать шаг)
- *              TECH/CONNECTION/USER_PARAM: строго prev.this + 1
- *
- *     Какие ошибки кидает:
- *       - LINE_ERR_UNSUPPORTED_TYPE_WITH_LINE
- *       - LINE_ERR_PARTIAL_FIELDS
- *       - LINE_ERR_NO_PREV
- *       - LINE_ERR_PREV_HASH_MISMATCH
- *       - LINE_ERR_LINE_CODE_MISMATCH
- *       - LINE_ERR_FIRST_STEP_BAD_THIS
- *       - LINE_ERR_THIS_LINE_BAD_STEP
- *
- * [2] trg_blocks_connection_state_ai  (AFTER INSERT ON blocks WHEN msg_type=3)
- *     Поддерживает таблицу connections_state как "текущее состояние" отношений:
- *       - FRIEND/CONTACT/FOLLOW  -> добавить/обновить состояние
- *       - UNFRIEND/UNCONTACT/UNFOLLOW -> удалить соответствующее "позитивное" состояние
- *
- * [3] trg_blocks_message_stats_like_ai (AFTER INSERT ON blocks WHEN msg_type=2 AND sub_type=LIKE)
- *     Поддерживает likes_count в message_stats для цели (to_*).
- *
- * [4] trg_blocks_message_stats_reply_ai (AFTER INSERT ON blocks WHEN msg_type=1 AND sub_type=REPLY)
- *     Поддерживает replies_count в message_stats.
- *
- * [5] trg_blocks_edit_apply_ai (AFTER INSERT ON blocks WHEN msg_type=1 AND sub_type=EDIT)
- *     Логика edit:
- *       - помечает исходный блок edited_by_block_number = NEW.block_number
- *       - увеличивает edits_count в message_stats
