# Architecture

`docforge` is split into four horizontal layers. Everything flows top to
bottom through the CLI.

## Loaders → Models

The `docforge/loaders` package wraps `griffe` to extract modules, functions,
classes, and Google-style docstring sections. Loaded data is normalized into
the object model under `docforge/models` (`Module`, `Object`, `Project`,
`Field`).

## Navigation

`docforge/nav` parses `docforge.nav.yml` specs (`NavSpec`, `Resolver`, and the
MkDocs nav emitter) and, since the wiki kind, derives wiki navigation from the
file structure via `build_wiki_nav`.

## Renderers

`docforge/renderers` turn model data into artifacts:

- `MkDocsRenderer` → `docs/lib/**` reference markdown
- `MCPRenderer` → `docs/mcp/**` structured documentation

## CLI

`docforge/cli` wires it all together:

- `commands.py` — the `build` command and its `--mkdocs` / `--api` / `--wiki`
  / `--mcp` modes
- `mkdocs_utils.py` — config generation (`mkdocs.yml`) including merged
  wiki + lib + api navigation
- `api_utils.py` — OpenAPI loading and API docs generation
