-- radar_feed_cache: single-row table holding the last verified feed JSON
--   (community or live tier). The payload is the exact byte-identical feed
--   returned by the Radar server after Ed25519 signature verification.
--
-- radar_settings: single-row table holding the operator's opt-in state and
--   an optional supporter key (encrypted at rest with AES-256-GCM via the
--   same mechanism used for provider connection credentials).
