# mosaicstack-telemetry (Python Client SDK)

Python client SDK for Mosaic Stack Telemetry. Reports AI coding task-completion telemetry and queries crowd-sourced predictions.

## Development

```bash
# Install dependencies (including dev)
uv sync --all-extras

# Run tests (85%+ coverage required)
uv run pytest

# Lint
uv run ruff check src/ tests/

# Format check
uv run ruff format --check src/ tests/

# Type check
uv run mypy src/
```

## Architecture

- `src/mosaicstack_telemetry/client.py` — Main TelemetryClient (public API)
- `src/mosaicstack_telemetry/config.py` — TelemetryConfig dataclass with env var support
- `src/mosaicstack_telemetry/queue.py` — Thread-safe bounded event queue
- `src/mosaicstack_telemetry/submitter.py` — Batch submission with retry/backoff
- `src/mosaicstack_telemetry/_sync.py` — Threading-based periodic submitter
- `src/mosaicstack_telemetry/_async.py` — Asyncio-based periodic submitter
- `src/mosaicstack_telemetry/event_builder.py` — Fluent event builder
- `src/mosaicstack_telemetry/prediction_cache.py` — TTL-based prediction cache
- `src/mosaicstack_telemetry/types/` — All Pydantic models and enums

## Key Rules

- `track()` must NEVER throw or block the caller
- All logging uses `logging.getLogger("mosaicstack_telemetry")`
- Runtime deps: httpx + pydantic only
- Python 3.10+ compatible (uses `str, Enum` mixin instead of StrEnum)
