+- Начинай с ближайшего локального `AGENTS.md` и файлов конкретной возможности. Карта документов: `docs/README.md`; реализация архитектуры: `docs/architecture.md`.
+- Web/desktop UI: `apps/web/src`; Android: `apps/mobile/src`; общие правила клиентов: `packages/core/src`; Go API: `services/api/internal`; рекомендации: `services/recommender/pipu_rec`.
+- Контракт HTTP — `api/openapi.yaml`. Читай нужную операцию и связанные схемы. Generated-код (`**/gen/**`, `**/generated/**`) и lock-файлы исследуй точечно; не редактируй вручную.
+- После изменения OpenAPI: `pnpm --filter @pipu/api-client generate`, затем из `services/api`: `go generate ./...`. Проверяй и коммить результат генерации.
+- Новые правила размещай у владельца сценария, IO — в адаптере. Сохраняй явные границы транзакций и платформенные особенности. Узкий интерфейс вводи для конкретного потребителя.
+- Промежуточно запускай проверки затронутой области; перед сдачей — необходимые связанные проверки. Команды запускаются из корня, если не сказано иначе.
+- Общие проверки: `pnpm typecheck`, `pnpm test`, `pnpm i18n:check`, `pnpm test:scripts`. Go: из `services/api` — `go vet ./...`, `go test ./...`. Python: из `services/recommender` — `uv run ruff check .`, `uv run mypy pipu_rec`, `uv run pytest`.
+- Не меняй пользовательские артефакты, локальные бинарники и посторонние незакоммиченные файлы.

 ## 5. Архитектурный стиль
 
 - **Модульный монолит** в `api`: каждый модуль в `internal/<module>` — `handler` (HTTP) → `service`
-  (бизнес-логика, интерфейсы) → `repository` (sqlc). Модули общаются через интерфейсы сервисов,
+  (операции приложения) → `store` (ручной SQL через pgx). Узкие порты отделяют изменяемые операции
-  не лезут в чужие таблицы напрямую.
+  от адаптеров; миграция существующих модулей постепенная. Read-проекции могут делать JOIN между областями.
 - **Contract-first**: `api/openapi.yaml` — источник истины. Go-сервер генерирует типы и интерфейс
   хендлеров (`oapi-codegen`, strict server), TS-клиент генерируется в `packages/api-client`.
   Сгенерированный код совпадает с контрактом.
 - **Внутренний API** `api ↔ recommender` и `api ↔ storage-agent` — HTTP/JSON во внутренней docker-сети,
-  описан отдельными `internal-*.yaml` спеками.
+  реализован Go/Python DTO и обработчиками; отдельных `internal-*.yaml` сейчас нет.
 - **Идемпотентность**: события и мутирующие запросы клиентов принимают `Idempotency-Key` / `event_id` (UUIDv7),
   что важно для офлайн-синхронизации мобильного.
 - **Деградация**: если `recommender` недоступен, `api` отдаёт волну по упрощённому fallback-алгоритму
   (похожие по жанрам + лайки + случайное), приложение продолжает работать.
 - **Наблюдаемость**: структурированные JSON-логи (`slog`, `structlog`), `/healthz` и `/readyz` у каждого сервиса,
   метрики Prometheus `/metrics` (опционально подключаются Grafana / Prometheus).

+## 6. Реализация и планы
+
+Точки изменения после выделения обязанностей:
+
+- `apps/web/src/player/player.ts` — фасад воспроизведения; `engine.ts`, `analysis.ts`, `media.ts`, `persistence.ts` — браузерные адаптеры. Типы состояния — `types.ts`.
+- `packages/core/src/wave.ts` — общая политика refill/feedback и поколения сессий. Web и Android сохраняют собственные очереди.
+- `apps/web/src/features/uploads` — API, queries, экран очереди, диалоги и настройки. Страница очереди только собирает feature.
+- `services/api/internal/library`: `sources.go`, `templates.go`, `scans.go`, `schedule.go` — отдельные сценарии; `Service` сохраняет фасад для HTTP и сборки приложения.
+- `services/api/internal/uploads`: `placement.go` планирует размещение через узкие порты, `persistence.go` владеет SQL-операциями и транзакциями.
+- `services/api/internal/playback/personalizer.go` персонализирует каталог независимо от HTTP; `events.go` принимает события в транзакции.
+
+`pnpm check:boundaries` проверяет новые границы без сборки приложений. Его отдельный CI workflow
+запускается при изменении соответствующих областей; read-проекции и composition root не запрещены.
+
+River и sqlc не используются. Сканер и расписание живут в процессе API; upload workers читают
+состояния PostgreSQL и пробуждаются каналами/таймерами. Анализатор использует `analysis_jobs`.
+Добавление устойчивой очереди или генератора SQL — отдельное архитектурное решение при появлении
+соответствующей потребности, не обязательная часть текущего рефакторинга.

+# Стоимость работы агентов и план SOLID-рефакторинга — 2026-10-22
+
+## Вывод и границы исходного исследования
+
+Проект уже имеет полезные границы: приложения разделены, есть общий `packages/core`, контракт OpenAPI, интерфейсы auth, отдельный Python-рекомендатель. Основная проблема — не количество технологий, а широкий контекст локальных изменений: несколько крупных оркестраторов смешивают правила, IO и состояние, а часть правил повторяется на клиентах.
+
+Проверены структура tracked-файлов, ключевые Go/TS/Python-компоненты, тесты, CI, документация и два примера изменений из git. Это архитектурное исследование с фокусом на трудоёмкости доработок, а не полный аудит безопасности, производительности или визуального UI. Непрочитанные исходники не считаются проверенными. На этапе исходного исследования код приложения не изменялся и тесты не запускались. Реализация и проверки следующего этапа описаны в конце отчёта.
+
+Фактические токены, стоимость и повторные попытки прошлых сессий не исследованы: в материалах проверки нет соответствующей телеметрии. Ниже — подтверждённые свойства репозитория и объяснение того, как они могут увеличивать работу агента. Процент экономии без замера не установлен.
+
+## Prior Reviews Summary
+
+В `docs/reviews/` найден один предыдущий отчёт: `2026-10-21-review-1.md`. Все 9 задач уже отмечены `[x]`, их повторно не открывали. Открытых задач для переноса: 0. Вновь подтверждённых исправлений ранее открытых задач: 0.
+
+## Измерения
+
+Снимок: HEAD `c84f90e`; локальные посторонние untracked-файлы не включены и не изменены.
+
+- 419 tracked-файлов.
+- 260 исходников с расширениями `.go`, `.ts`, `.tsx`, `.py`, `.rs`, исключая каталоги `gen`, `generated` и файлы `.gen.go`: 39 605 строк, включая тесты.
+- Из этих исходников 24 файла длиннее 400 строк, 9 — длиннее 600. Длина — сигнал для изучения обязанностей, не самостоятельное нарушение SOLID.
+- `services/api/internal/api/gen/api.gen.go`: 11 234 строки.
+- `packages/api-client/src/generated/schema.ts`: 4 599 строк.
+- `pnpm-lock.yaml`: 8 523 строки.
+- Итого эти три файла: 24 356 строк. Их полный вывод в контекст обычно избыточен; это не оценка числа токенов.
+- `api/openapi.yaml`: 3 717 строк. Контракт нужен, но обычно достаточно конкретной операции и связанных схем.
+
+Воспроизведение: список из `git ls-files`, подсчёт через `[System.IO.File]::ReadAllLines`, отбор расширений и указанных generated-путей. Это физические строки, без семантического анализа. Наличие файла в git не означает, что агент автоматически загружает его целиком.
+
+## Почему работа агента может быть дорогой
+
+### 1. Недостаточно локальной навигации
+
+В проверенном дереве не найдены `AGENTS.md`; корневой README даёт общие команды, `docs/README.md` — карту продуктовых документов. Нет краткой карты «задача → владельцы кода → инварианты → целевые проверки». Новая сессия вынуждена восстанавливать её поиском.
+
+Нужна короткая корневая инструкция и локальные инструкции по областям, с минимальным пересечением. Большая энциклопедия в корневом AGENTS сама увеличит постоянный контекст. Исключения для generated-кода должны означать «читать точечно при необходимости», а не запрещать проверку контракта.
+
+### 2. Документация описывает частично проектируемую архитектуру как существующую
+
+`docs/architecture.md:34`, `:63`, `:101`, `:123`, `:129` обещают River, sqlc, общение модулей через сервисные интерфейсы и отдельные внутренние YAML-спецификации. В проверенном `services/api/go.mod` нет River/sqlc, сканирование запускает `Scanner.Start` (`library/service.go:614`), SQL находится прямо в store/service, в `api/` найден публичный `openapi.yaml`.
+
+Агенту приходится перепроверять описание. Документ следует разделить на «реализовано» и «планируется», описать действующие очереди/воркеры и не внедрять River/sqlc только ради соответствия старому тексту.
+
+### 3. Слишком широкий контекст плеера
+
+`apps/web/src/player/player.ts:84` — 896 строк: очередь, волна, события, HTMLAudioElement, crossfade, preloading, Web Audio, Media Session, Tauri media, localStorage и серверное восстановление. Изменение одной обязанности требует проверки остальных.
+
+`apps/mobile/src/player/controller.ts:78` — 457 строк с похожей оркестрацией, но другим движком, офлайн-хранилищем и фоновым жизненным циклом. Одинаковые `WAVE_REFILL_AT`, `EARLY_SKIP_MS`, накопление feedback и `refillWave` находятся в обоих клиентах (`web:255`, `mobile:375`). Правку правила нужно сопоставлять в двух реализациях.
+
+### 4. Границы backend непоследовательны
+
+- `uploads/service.go:31–52` зависит от конкретных Store, library.Service и Scanner; `:328` обращается к `s.store.pool.Exec`, `:387` принимает `pgx.Tx` в бизнес-операции.
+- `library/service.go:49` объединяет источники, подключение, шаблоны, preview, сканирование, расписание и health-check; всего 829 строк.
+- `playback/handler.go:37` объединяет стриминг, персонализацию, события, состояние, историю и реакции; всего 609 строк, использует конкретный `library.Store`.
+- `cmd/api/main.go:157–160`: DTO ссылается на playback Handler, а Handler получает DTO через замыкание. Это усложняет сборку и изолированное тестирование. Это не цикл импортов Go.
+- `genius/service.go:27` сам создаёт внешний клиент, а также работает с БД и запускает worker. Прямая зависимость от внешнего клиента затрудняет его замену в тесте.
+
+Чтение чужих таблиц в поисковой проекции само по себе допустимо. Главный приоритет — изолировать бизнес-операции и записи; не вводить универсальные репозитории для всех JOIN.
+
+### 5. Проверки не всегда соответствуют границам изменений
+
+Уже есть полезные unit-, integration- и E2E-тесты; CI API и PostgreSQL integration разделены. Но `apps/mobile/test/screens.test.ts` проверяет offlineWave/releaseNeed, а не Controller. В проверенном наборе `apps/mobile/test` нет сценариев жизненного цикла Controller.
+
+`apps/web/src/player/audio.test.ts:15` подменяет внутреннее состояние Player через `Object.assign`. Это конкретный признак неудобной тестовой границы: тесту нужен маленький анализатор, но приходится собирать большой плеер и менять его внутренности.
+
+Без быстрых поведенческих проверок изменяемого модуля агенту требуется больше рассуждений и более широкий прогон. Наличие тестов не доказывает покрытие всех гонок.
+
+### 6. Часть ширины изменений оправдана продуктом
+
+Добавление Genius (`73ad61e`) затронуло 34 файла, включая миграцию, оба клиента, переводы и generated-код. Это сквозная возможность, и само число файлов не доказывает плохую архитектуру. Добавление текущего трека в плейлист (`fb20258`) затронуло 8 файлов, не потребовало переделки backend.
+
+Уменьшать нужно непредвиденную связанность и повторное открытие одних и тех же файлов, сохраняя необходимые контрактные, платформенные и локализационные изменения.
+
+## Phase 1: Code Quality / SOLID
+
+### S — одна причина для изменения
+
+Выделить у веб-плеера `AudioEngine`, `AudioAnalysis`, `PlaybackPersistence`, `MediaControls`. Player сохранить как фасад с текущим публичным API. Сначала вынести наиболее независимые обязанности с сохранением поведения; не переносить весь плеер за один PR.
+
+Разделить library по сценариям: управление источниками, шаблоны/preview, запуск сканов, расписание/проверки доступности. Простое разнесение методов того же Service по файлам улучшит поиск, но не уменьшит связанность без разделения зависимостей.
+
+### O — расширение через ограниченные точки замены
+
+Вынести одинаковую политику волны в `packages/core` как `WaveSession`/`WaveCoordinator`: session generation, feedback, пороги refill и отбрасывание устаревших ответов. Сетевой API передавать через небольшой `WaveGateway`.
+
+Web и Android применяют результат к собственным очередям. Native queue, offline playback и особенности ExoPlayer остаются в Android-адаптере; единый абстрактный движок для всех платформ заранее не нужен.
+
+### L — заменяемость
+
+Доказанных нарушений LSP в исследованной области не обнаружено. Для новых адаптеров проверять одинаковые обещания: порядок результатов, ошибки, отмену и отсутствие воздействия устаревшей сессии. Синхронный HTMLAudioElement и асинхронный native player нельзя объявлять взаимозаменяемыми без явного контракта.
+
+### I — узкие интерфейсы
+
+`auth/store.go:43` объединяет пользователей, refresh-токены, администрирование, audit и настройки; `WithTx` возвращает тот же широкий Store. Это кандидат на последующее разделение по потребителям, но auth уже имеет рабочий интерфейс и тестовый memstore — приоритет ниже плеера/uploads.
+
+Новые границы создавать по реально используемым операциям, например `SourceLookup`, `ScanStarter`, `PlacementCatalog`. Не копировать все методы конкретного Store в интерфейс.
+
+### D — зависимость от операций, а не инфраструктуры
+
+В uploads вынести SQL и pgx-транзакции в persistence-адаптер; сервису дать операции `UpdateMetadata`/`Approve`/`Reject` с согласованными результатами. Сохранить атомарность смены статуса, квот и метаданных решения. Интеграционный тест реальной БД обязателен для изменений транзакций.
+
+Выделить персонализацию каталога из HTTP Handler в самостоятельный объект; DTO и playback получают его при сборке. Конкретные зависимости в composition root (`main.go`, `server/router.go`) нормальны, массовое оборачивание всех конструкторов интерфейсами пользы не даст.
+
+### Performance / Correctness
+
+Новые подтверждённые runtime-дефекты и измеренные проблемы производительности этим исследованием не установлены. Размер SQL-запроса или исходника не считается доказательством медленной работы. Метрики качества рекомендаций и сетевого воспроизведения не измерялись.
+
+## Phase 2: Logical Consistency
+
+Целевой путь backend: HTTP handler → операция приложения → узкие порты → PostgreSQL/файлы/HTTP. Границы транзакций остаются явными. Межмодульные операции используют контракты потребителя; read-модели могут сохранять обоснованные JOIN.
+
+Целевой путь клиента: UI → фасад плеера/feature → общие правила → платформенный адаптер. Для каждого состояния нужен один владелец. На Android владельцем воспроизводимой очереди остаётся native player; общий core не становится второй конкурирующей очередью.
+
+Generated-типы оставить на HTTP-границах. Не создавать копии всех DTO ради формального разделения слоёв. Независимую модель вводить там, где правило использует небольшой стабильный набор полей.
+
+## Phase 3: UI/UX
+
+`apps/web/src/pages/admin/UploadQueuePage.tsx` содержит экран, строку очереди, пакетное редактирование, редактирование файла, отклонение и настройки загрузок (`:30`, `:205`, `:353`, `:422`, `:503`, `:542`), всего 640 строк. Настройки экспортируются из файла страницы очереди, сетевые вызовы находятся в компонентах.
+
+Вынести в `features/uploads`: API/queries, экран очереди, отдельные диалоги, настройки. Странице оставить сборку. Сохранять ключи React Query и правила invalidation; единый большой `useUploadsEverything` лишь переместит проблему.
+
+Новых визуальных и accessibility-дефектов не заявлено: браузерная проверка не проводилась. Закрытые задачи мобильного UI из прошлого ревью не дублировались.
+
+## Порядок внедрения и условия готовности
+
+1. **Навигация и достоверность.** Короткие инструкции по областям, актуальная архитектура, карта локальных проверок. Для типовой задачи понятны 2–5 начальных файлов и команды без чтения всех docs. Это ориентир, а не запрет на более широкий поиск.
+2. **Упростить Player, сохранив фасад.** Сначала persistence/media/analysis; отдельно engine/crossfade. Проверки: restore без autoplay, ошибка preload и повтор Play, пауза/seek, очистка обработчиков. Существующие тесты сохранить; новые нужны для поведения на новой границе.
+3. **Общая политика волны.** Сначала зафиксировать сценарии, затем подключать web и Android по отдельности. Проверки: поздний ответ после смены сессии, retry feedback, refresh очереди, ранний skip. На устройстве — background playback и offline→online.
+4. **Uploads.** Сначала выделить persistence-операции с сохранением транзакций, затем placement и worker-порты. Проверки: конкурирующие решения, квота, повторный import, восстановление после рестарта, очистка staging; результат на реальной БД и файловые побочные эффекты.
+5. **Library / playback / catalog.** Разделить use cases и убрать DTO→HTTP Handler из персонализации. Сохранить HTTP-контракт, подписи stream URL и поведение X-Accel. Проверять персонализацию батча, реакции, history/state и fallback wave.
+6. **Локализация UI и закрепление границ.** Разделить uploads feature. Добавить автоматическую проверку запрещённых зависимостей с точными исключениями для composition root и проекций. Отложить дробление auth до изменения соответствующей функциональности.
+
+Каждый шаг — отдельное ревьюируемое изменение. Сначала выделение границ без изменения поведения, затем новые возможности. Generated-файлы обновлять штатными генераторами; публичный OpenAPI не дробить до появления измеримой проблемы и готового процесса сборки спецификации.
+
+## Как проверить экономию
+
+Взять сравнимые задачи до/после: изменение порога волны на обоих клиентах, изменение правила размещения upload, добавление поля настроек загрузок. Не сравнивать эти разные задачи между собой; фиксировать модель, режим рассуждения и применённые навыки.
+
+Для каждой записывать input/cached input/output tokens, если доступны; отдельно число прочитанных файлов, объём вывода инструментов, повторные чтения, итерации исправлений, длительность проверок и затронутые модули. Сопоставлять распределение нескольких задач, а не один удачный запуск.
+
+Немедленные меры: `rg` по символам, чтение диапазонов, ограниченный вывод, исключение generated/lock из общего исследования, целевые проверки на промежуточных шагах и необходимые полные проверки перед сдачей. Крупные patch/diff тоже читать сначала без generated, затем отдельно проверять генерацию.
+
+Выбор workflow влияет независимо от кода: полный аудит полезен для такого исследования, но запуск всех его фаз на маленькой правке добавляет работы. Большой каталог навыков, системные инструкции и история чата также могут занимать контекст; их вклад и кэширование не измерены и не устраняются рефакторингом приложения.

+
+## Исправления — 2026-10-22
+
+Реализованы все 8 задач по коду; внешняя проверка PostgreSQL и физического Android остаётся отдельным условием валидации. Исходные метрики и ссылки выше описывают состояние до исправлений.
+
+1. Добавлены компактные корневой и локальные `AGENTS.md`; README ссылается на карту работы. Общая инструкция не загружает всю документацию.
+2. Архитектура описывает реальные pgx-запросы, in-process scanner и статусные upload jobs; River/sqlc/internal YAML отделены от реализации. Добавлена актуальная карта компонентов.
+3. Player сохраняет прежний интерфейс, а аудиограф/элементы, анализ, Media Session/Tauri и сохранение выделены в `engine.ts`, `analysis.ts`, `media.ts`, `persistence.ts`. Типы состояния отделены. Обработчики аудио и media освобождаются, отложенное сохранение отменяется при dispose. Player: 896 → 617 строк; crossfade и оркестрация очереди остаются в фасаде.
+4. `WaveCoordinator` в core обслуживает пороги, feedback и версии запросов на обеих платформах. Поздние ответы/ошибки не меняют новую сессию; смена контекста сохраняет ещё не отправленный feedback. На Android добавлены проверки Controller после reset и ручного выбора списка, native queue остаётся владельцем воспроизведения.
+5. SQL и pgx убраны из uploads service/worker. `persistence.go` предоставляет атомарные операции изменения метаданных, решений и завершения импорта; транзакционный механизм Transition сохранён. Выделен PlacementPlanner и порты SourceCatalog/RootResolver/ImportedScanner. Guarded UPDATE теперь сообщает конфликт, если статус успел измениться. Добавлены integration-проверки rollback решения, конкурирующих отказов, quota и повторного завершения импорта; без PostgreSQL они не исполнялись.
+6. Library Service стал фасадом над SourceService, TemplateService, ScanService и Scheduler. Зависимости разделены интерфейсами. Результат health-check передаётся через канал, исключая общую запись из timeout и worker веток.
+7. Personalizer отделён от HTTP Handler, DTO собирается напрямую без замыкания. Приём событий выделен в EventService; остальные playback-сценарии остаются в существующем handler для постепенного дальнейшего разделения. Unit-тесты проверяют батч персонализации, недоступные треки и ошибки чтения.
+8. Страница очереди стала оболочкой из 3 строк; feature содержит экран (181 строка), отдельные диалоги, строки списка, настройки, API и queries. Ключи запросов и invalidation сохранены. Локальные тесты проверяют сохранение метаданных и сохранность формы при конфликте.
+
+Дополнительно: `pnpm check:boundaries` и отдельный CI workflow проверяют введённые границы без сборки всего проекта. Проверка целевая, не заменяет полноценный анализ графа импортов.
+
+### Проверки
+
+- Web typecheck и production build — успешно.
+- Web unit/component suite — 51 тест успешно; в том числе restore без autoplay, ошибки preload и новые диалоги.
+- Playwright — 10 сценариев успешно: desktop и mobile layouts, очередь/диалоги, навигация и плеер.
+- Core — 39 тестов успешно, включая 4 сценария WaveCoordinator.
+- Android typecheck — успешно; unit-тесты — 5 успешно, включая 2 сценария Controller с заглушкой native-плеера.
+- `go test ./...` и `go vet ./...` — успешно. Новые unit-тесты library/playback проходят.
+- Integration build — успешно; `TestMigrationsUpDownUp`, `TestLibraryAndUploads`, `TestPlaylistPersistenceAndIsolation`, `TestUserJourney` явно **SKIP**: не задан `TEST_DATABASE_URL`, Docker daemon недоступен. Результат не подтверждает транзакции на реальной БД.
+- Физический Android/background/offline→online не проверялся.
+- Публичный OpenAPI и generated-код не менялись. Экономия токенов после рефакторинга ещё не измерена.
