Миграция 00004: таблицы `messages`, `message_reactions`, `channel_read_states`, `files`, `invites` и виртуальная таблица `messages_fts` с триггерами синхронизации (AGENT.md 6.1, 7.6, 7.7, 7.9, 7.15, 7.16). Полнотекстовый поиск требует сборки с тегом `sqlite_fts5`: - `GO_TAGS ?= sqlite_fts5` в Makefile (build/test/cover) и в Dockerfile; - build-tags в golangci-lint; - страж `internal/database/fts5_guard.go`: сборка без тега падает с понятным текстом, а не ломается на миграции в рантайме.
