TrackShort.Lyrics was SupplementLyrics but Python reference shows it should be TrackLyricsInfo
(has_available_sync_lyrics, has_available_text_lyrics fields)

+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+This is a Go port of the [yandex-music-api](https://github.com/MarshalX/yandex-music-api) Python library. The original Python library is in `yandex-music-api-python/` and serves as the reference implementation.
+
+The Python library provides:
+- **Sync and async HTTP clients** for Yandex Music API
+- **Ynison protocol support** for player synchronization across devices
+- **Radio sessions** (My Wave, generative stations)
+- **High-level wrapper objects** (Track, Album, Artist, Playlist, etc.)
+- **Schema mismatch handling** for API evolution
+- **Multiple JSON backend support** (orjson, pydantic-core, ujson, stdlib json)
+
+## Python Library Architecture (Reference)
+
+### Core Structure
+```

+├── client.py              # Sync Client (main entry point)
+├── client_async.py        # Async ClientAsync
+├── _client_base.py        # Shared base class with common attributes
+├── base.py                # YandexMusicObject base model with de_json/de_list
+├── exceptions.py          # Custom exceptions

+│   ├── request_async.py   # Async HTTP request handling
+│   ├── json_backend.py    # Pluggable JSON backends
+│   └── schema_mismatch.py # Schema mismatch reporting
+├── _client/               # Generated sync method mixins (20+ files)
+├── _client_async/         # Generated async method mixins
+├── track/, album/, artist/, playlist/, etc.  # Model packages
+├── ynison/                # Ynison protocol (WebSocket)
+│   ├── client.py          # Sync Ynison client

+│   └── models/            # Protobuf-generated models
+└── supplement/            # Lyrics, video supplements
+```
+
+### Key Patterns
+- **Mixin-based Client**: `Client` inherits from 20+ mixins (AccountMixin, AlbumsMixin, TracksMixin, etc.)
+- **Model deserialization**: Each model has `de_json(data, client)` and `de_list(list_data, client)` classmethods
+- **Request signing**: Requests to `api.music.yandex.net` are signed with a custom algorithm
+- **Device auth**: OAuth Device Flow for token acquisition
+- **Generated code**: Sync/async clients and models are partially code-generated from OpenAPI spec

+## Development Commands
+
+### Go Toolchain
+```bash
+# Initialize module (run once)
+go mod init github.com/your-org/yandex-music-api-go
+
+# Download dependencies
+go mod tidy
+
+# Build
+go build ./...
+
+# Run tests
+go test ./...
+
+# Run tests with coverage
+go test -cover ./...
+
+# Run single test
+go test -v -run TestName ./path/to/package
+
+# Lint (requires golangci-lint)
+golangci-lint run
+
+# Format
+go fmt ./...
+
+# Vet
+go vet ./...
+
+# Generate code (if using code generation)
+go generate ./...
+```
+
+### Protobuf (for Ynison)
+```bash
+# Install protoc and plugins
+go install google.golang.org/protobuf/cmd/protoc-gen-go@latest
+go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest
+go install github.com/bufbuild/buf/cmd/buf@latest  # optional, for buf.yaml workflow
+
+# Generate from .proto files
+protoc --go_out=. --go_opt=paths=source_relative \
+       --go-grpc_out=. --go-grpc_opt=paths=source_relative \
+       internal/ynison/proto/*.proto
+
+# Or with buf
+buf generate
+```
+
+## Key Implementation Notes
+
+### Request Signing
+The Python library signs requests with a custom algorithm. Port this exactly from `yandex_music/utils/request.py`:
+- Request parameters are sorted and concatenated
+- Signed with a secret key
+- Signature added as `sign` parameter
+
+### JSON Handling
+Go's standard `encoding/json` is fast enough. No need for multiple backends. Use `json.RawMessage` for flexible fields.
+
+### Schema Mismatch Handling
+Port the Python `SchemaMismatch` logic:
+- Track unknown fields in API responses
+- Configurable: ignore, warn, or strict (error)
+- Callback support for custom handling (e.g., Sentry)
+
+### Ynison Protocol
+- Uses WebSocket with protobuf messages
+- Python uses `betterproto` for protobuf; Go uses standard `protobuf` module
+- Port the message types from `yandex_music/ynison/models/`
+
+### Model Structure
+Follow Python patterns:
+```go
+// Base interface for all models
+type Model interface {
+    // DeJSON deserializes from JSON
+    DeJSON(data []byte, client *Client) (Model, error)
+    // DeList deserializes a list
+    DeList(data []byte, client *Client) ([]Model, error)
+}
+```
+
+### Client Design
+- Single `Client` struct with methods (not mixins - Go doesn't have them)
+- Group methods by feature using separate files: `client_tracks.go`, `client_albums.go`, etc.
+- Support both sync and async (context-based) patterns
+
+## Testing Strategy
+- Unit tests for models (de/serialization)
+- Integration tests against mock server (use `httptest`)
+- Test schema mismatch handling
+- Test request signing
