# `means.types`: Core Accounting Data Model

```{py:currentmodule} means.types
```

The `types` subpackage defines the pydantic models and enums that represent a plain-text accounting system: `Account` paths and their `AcctType` valences, the people (`User`) and institutions (`Bank`, `BankAccount`) involved, individual `Post` lines, balanced `Transaction` entries and their inferred `TransType`, declarative transformation rules (`Route`), and the `Ledger` files that tie them all together.

Every class follows a one-class-per-file layout and is re-exported here for convenient access.
