"""Book-only granular backtester package.

This package provides an event-driven backtesting engine operating solely on
order book snapshots streamed from an aggregated SQLite database. It is scoped
to long-only strategies for the initial implementation.

Modules are intentionally small and composable. The CLI entrypoint is
`book_backtest.cli` with subcommands for initializing the aggregated database,
ingesting source OKX book databases, and running a backtest.
