Moves an app to a project.

It sets the declaration's `partOf` — in its cluster overlay when the overlay
sets the key, else in its values file — and nothing else. Naming a project
nothing names yet creates it. `org` is the values directory the app lives in;
`mode` as for create.

## Request

5 fields, body `application/json` (required).

| Field    | In   | Type   | Required | Description                                                                       |
| -------- | ---- | ------ | -------- | --------------------------------------------------------------------------------- |
| `app`    | path | string | yes      | App is the declaration's name, from the path.                                     |
| `app`    | body | string | —        | App is the declaration's name, from the path.                                     |
| `mode`   | body | string | —        | Mode is `branch` (the default) or `commit`.                                       |
| `org`    | body | string | —        | Org is the values directory the app lives in, defaulting to the caller's own org. |
| `partOf` | body | string | —        | PartOf is the project to move it to.                                              |

## Response

| Status    | Body                  | Meaning |
| --------- | --------------------- | ------- |
| `200`     | platform.projectWrite | ok      |
| `default` | problem-details       | refused |

`200` body — 11 fields.

| Field          | In   | Type                | Always | Description                                                        |
| -------------- | ---- | ------------------- | ------ | ------------------------------------------------------------------ |
| `commit`       | body | string              | —      | Commit is the sha the change created, "" when nothing had to move. |
| `live`         | body | boolean             | —      | Live says whether the generator will see it: true only on main.    |
| `mode`         | body | string              | —      | Mode is branch (a review; nothing deploys) or commit (main).       |
| `moved`        | body | platform.relabel\[] | —      | Moved are the declarations whose partOf moved, and from what.      |
| `moved[].from` | body | string              | —      |                                                                    |
| `moved[].name` | body | string              | —      |                                                                    |
| `moved[].org`  | body | string              | —      |                                                                    |
| `moved[].to`   | body | string              | —      |                                                                    |
| `project`      | body | string              | —      | Project is the project the change leaves the moved apps in.        |
| `ref`          | body | string              | —      | Ref is the branch the change was pushed to, main for a commit.     |
| `review`       | body | string              | —      | Review is where to open the pull request for a branch.             |

Failure carries the platform error shape — see [Errors](https://docs.hanzo.ai/docs/errors).

## Examples

**CLI**

`hanzo` has no subcommand for this operation — the CLI serves only what cloud's live route table confirms. Use HTTP or an SDK.

**SDK**

**.ts**

```ts
import { Configuration, PlatformApi } from 'hanzoai';

const api = new PlatformApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.putPlatformAppsByAppProject({ app: 'app', app: "<app>", mode: "<mode>" });
```

**.py**

```python
from hanzoai.cloud import ApiClient, Configuration
from hanzoai.cloud.api import PlatformApi

client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"]))
result = PlatformApi(client).put_platform_apps_by_app_project(app='app', app="<app>", mode="<mode>")
```

**.go**

```go
cfg := hanzoai.NewConfiguration()
cfg.AddDefaultHeader("Authorization", "Bearer "+os.Getenv("HANZO_API_KEY"))
client := hanzoai.NewAPIClient(cfg)

resp, _, err := client.PlatformAPI.PutPlatformAppsByAppProject(context.Background()).Execute()
if err != nil {
	return err
}
```

**.rs**

```rust
use hanzo_client::apis::{configuration::Configuration, platform_api};

let mut cfg = Configuration::new();
cfg.bearer_access_token = std::env::var("HANZO_API_KEY").ok();

let result = platform_api::put_platform_apps_by_app_project(&cfg, Default::default()).await?;
```

**.java**

```java
import ai.hanzo.cloud.ApiClient;
import ai.hanzo.cloud.api.PlatformApi;

ApiClient client = new ApiClient();
client.setBearerToken(System.getenv("HANZO_API_KEY"));

var result = new PlatformApi(client).putPlatformAppsByAppProject();
```

**HTTP**

```bash
curl -X PUT https://api.hanzo.ai/v1/platform/apps/<app>/project \
  -H "Authorization: Bearer $HANZO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
       "app": "<app>",
       "mode": "<mode>"
     }'
```

**MCP**

MCP reaches **platform** through the `platform` tool, which names its 38 operations with its own verbs — this one among them, under a name only MCP declares. `describe` explains any of them:

```bash
curl -X POST https://api.hanzo.ai/v1/mcp \
  -H "Content-Type: application/json" \
  -d '{
       "jsonrpc": "2.0",
       "id": 1,
       "method": "tools/call",
       "params": {
         "name": "describe",
         "arguments": {
           "op": "get_build"
         }
       }
     }'
```
