External properties are resolved from a connected provider (GitHub, Slack, etc.) rather than entered by a user. Custral pulls the value on a freshness schedule and caches it on the field.
The latest value pulled from the provider, along with when it was last fetched and the source it was looked up from. If a fetch fails, the property keeps the last known value and shows the error.
Available filters depend on the provider and resource, for example, filtering by a pull request’s state, by whether the value is stale, or by whether it’s set at all.
