Key validation on arbitrary number of properties.

I'm working on validating an object where: - Some property keys are known and expected. - Other extra/unknown keys are allowed only if they follow a specific pattern. Pattern for extra keys: Keys should match the format:
metafield.<namespace>.<key>
Where: - namespace and key can contain alphanumeric characters, underscores, or hyphens. Here's the regex I'm using:

const regex = /^metafield\.[a-zA-Z0-9_-]+\.[a-zA-Z0-9_-]+$/;

const regex = /^metafield\.[a-zA-Z0-9_-]+\.[a-zA-Z0-9_-]+$/;

Example payload:

{
    "knownkey": "value",
    "metafield.test.key": "value",
    "metafield.test.key2": "value",
    "metafield.test.key3": "value",
    "metafield.test.key4": "value"
}

{
    "knownkey": "value",
    "metafield.test.key": "value",
    "metafield.test.key2": "value",
    "metafield.test.key3": "value",
    "metafield.test.key4": "value"
}

Question: How can I define a Arktype type that allows: - Some known, explicitly typed keys. - And any number of extra keys that match the regex pattern above?
