# Filter: gk/foundation/integrity/revocation-url

Filters the revocation feed URL.

Used by local/staging environments to point at a test worker. Production sites should never override this — a rogue URL defeats revocation enforcement on cold start because the durable copy is read without re-verification.

## Parameters

| Name | Type | Description |
|------|------|-------------|
| $url | `string` | Default revocation feed URL. |

### Since
