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_-]+$/;


Example payload:

{
    "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?
