THE answer to 'is <service> connected?' - every connected account/instance this company has (service, instance, accountId, region), filterable with `service` and narrowed with `match` (looking for one plane's instance? pass `match` - the full list is ~50 rows). Pass an instance as connections_execute's `instance` to target one. Two kinds: a normal row holds a credential in this vault; a kind:'brokered' row is owned by ANOTHER first-party plane (named in `via`) that holds the credential - notably every Stripe account linked through Pay, which you reach with Pay endpoints per the row's `callWith`, NOT with service:'stripe'. Stripe can appear BOTH ways at once and they are different accounts: a brokered row is Pay's Connect link, while a normal stripe row is a secret key this workspace pasted directly and IS called with service:'stripe' as its own instance - so read the row's `kind` before choosing how to call it. A `brokeredUnavailable` field means that plane could not be reached, so the list is INCOMPLETE - never read it as 'not connected'.
