Receiver.spec.resources[].filter

Filter is a CEL expression expected to return a boolean that is evaluated for each resource matched by this reference when a webhook is received, in addition to the top-level resourceFilter. A reconciliation is requested only when both expressions (when set) return true. The expression can read the resource metadata via 'res' and the webhook request body via 'req'. For generic-oidc receivers, the verified OIDC token claims are also available via 'claims'. When the expression is specified the controller will parse it and mark the object as terminally failed if the expression is invalid or does not return a boolean.
