API overview

Public symbols are exported from entie (and re-exported entei-core helpers where noted). Source paths are relative to the repository root.

Top-level (`entie`)

Symbol	Description
`connect`	Build an `EntieMongoClient` / `EntieDatabase` from a URI, optional `ENTIE_URI`, or an existing `MongoClient`.
`EntieMongoClient`	Thin wrapper around PyMongo’s `MongoClient`; use `database(name)` for `EntieDatabase`.
`EntieDatabase`	Holds a PyMongo Database (not a collection). `table` / `collection` return collections.
`EnteiDataFrame`	Lazy, collection-backed frame: `from_collection`, `filter_rows`, `select`, `collect`.
`Records`	Row-oriented insert helper: `from_list`, `insert_into`.
`col` / `column`	Expression helpers for dataframe-style operations.
`lit`	Literal expression helper.
`__version__`	Package version string.

Symbol	Description
`MongoRoot`	Columnar root `dict[str, list]` plus metadata for a Mongo collection snapshot.
`materialize_root_data`	Materialize documents into columnar form.
`mongo_root_to_column_dict`	Convert a `MongoRoot` to a plain column dict.

Module	Role
`entie.client`	`connect`, `EntieMongoClient`, `EntieDatabase`.
`entie.dataframe`	`EnteiDataFrame`.
`entie.io.records`	`Records`.
`entie.expressions`	`col`, `column`, `lit`.
`entei_core`	Core materialization only (also usable without `entie`).
