`gize-generator` turns [`gize-core`](https://crates.io/crates/gize-core) specs into files,
**safely**. It has three responsibilities:

1. Render file contents from model/project specs (via
   [`gize-templates`]https://crates.io/crates/gize-templates,
   [`gize-openapi`]https://crates.io/crates/gize-openapi and
   [`gize-admin`]https://crates.io/crates/gize-admin).
2. Write those files without ever clobbering user code, honoring `--force` and `--dry-run`
   (see [ADR-012]https://github.com/robertolima-dev/gize/blob/main/ADR/adr-012-cli.md).
3. Reconcile a project from its manifest (`gize sync`) and expose a small plugin API so third
   parties can add their own generators.

## Key types

- **`Plan`, `FileOp`, `OpKind`**: a pure, inspectable description of what will be written
  (create / skip / update) before anything touches disk.
- **`Writer`, `Options`, `Report`**: executes a `Plan`, applying the safety model and
  returning a report of what happened.
- **`sync`**: reconciles the tree against the manifest, classifying each file as missing,
  drifted or unchanged, and creating only what is missing unless `--force` is given.
- **`register_module`, `Edit`**: idempotent registry edits that wire new modules into
  `app/mod.rs` without disturbing surrounding code.
- **`Generator`, `GenContext`** (`plugin`): the v0 plugin API. A plugin returns a `Plan`, so
  it inherits the same safe writer for free (see
  [ADR-008]https://github.com/robertolima-dev/gize/blob/main/ADR/adr-008-plugins.md).

## The safety model

- Existing files are **skipped** unless `--force` is passed.
- `--dry-run` produces a full `Plan` and writes nothing.
- Registry edits and `sync` are **idempotent**: re-running never duplicates or clobbers.

## Usage

```toml
[dependencies]
gize-generator = "0.7"
```
