Seeds the native todo with the EXISTING Linear issues the
caller's key can see (default state=open); the webhook keeps them live
thereafter. Synchronous and bounded, idempotent by ExtRef.

## Request

1 field, body `application/json` (required).

| Field   | In   | Type   | Required | Description                                                                  |
| ------- | ---- | ------ | -------- | ---------------------------------------------------------------------------- |
| `state` | body | string | —        | State is the set of issues to walk: "open" (the default), "closed" or "all". |

## Response

| Status    | Body                          | Meaning |
| --------- | ----------------------------- | ------- |
| `200`     | provider.linearBackfillResult | ok      |
| `default` | problem-details               | refused |

`200` body — 5 fields.

| Field       | In   | Type            | Always | Description                                                                    |
| ----------- | ---- | --------------- | ------ | ------------------------------------------------------------------------------ |
| `created`   | body | integer (int64) | —      | Created is how many native issues this pass created.                           |
| `failed`    | body | integer (int64) | —      | Failed is how many issues errored; the pass continues past each.               |
| `issues`    | body | integer (int64) | —      | Issues is how many Linear issues were seen.                                    |
| `truncated` | body | boolean         | —      | Truncated is set when the time budget or the issue cap stopped the pass early. |
| `updated`   | body | integer (int64) | —      | Updated is how many existing native issues this pass refreshed.                |

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

## Examples

**CLI**

```bash
hanzo provider linear issues backfill
```

**SDK**

**.ts**

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

const api = new ProviderApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.postProviderLinearIssuesBackfill({ state: "<state>" });
```

**.py**

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

client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"]))
result = ProviderApi(client).post_provider_linear_issues_backfill(state="<state>")
```

**.go**

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

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

**.rs**

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

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

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

**.java**

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

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

var result = new ProviderApi(client).postProviderLinearIssuesBackfill();
```

**HTTP**

```bash
curl -X POST https://api.hanzo.ai/v1/provider/linear/issues/backfill \
  -H "Authorization: Bearer $HANZO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
       "state": "<state>"
     }'
```

**MCP**

MCP reaches **provider** through the `provider` 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": "list_connections"
         }
       }
     }'
```
