-- What the app has actually put on the Linka Go restriction list.
--
-- The platform offers no way to read that list back, so the only honest record
-- of it is the one kept here: each tick compares the addresses that *should* be
-- allowed right now against this table, and calls the api for the difference.
-- A row is written only once the call has succeeded, so a failed call is simply
-- retried at the next tick.
