-- 0079_acquisition_services.up.sql — the indexers and download clients the
-- operator adds in Admin → Integrations (Scribe milestone #502, #5518).
--
-- Minstrel replaces Lidarr, so it searches and downloads itself. Nothing is
-- seeded and nothing is copied from Lidarr: a connection is a row the operator
-- adds, from a list of what Minstrel can speak. Ported from Fabled
-- Librarian's acquisition_services (its migrations 0044, 0055, 0062, 0064,
-- 0070), which settled the shape:
--
--   kind      which list the row appears in: search (Indexers) or download
--             (Download clients).
--   protocol  which client is built: prowlarr (its native /api/v1/search,
--             because Prowlarr has no aggregate Torznab feed), torznab (any
--             single feed), qbittorrent (the WebUI v2), exchange.
--
-- FabledExchange is ONE row under Download clients with a switch per job:
-- downloading, searching its DHT index, and describing a torrent's files and
-- swarm before a grab. The serves_* switches mean something on an exchange
-- row only; every other row does the one job its kind names.
--
-- Secrets (api_key, password) are write-only: no query the API answers with
-- returns them, only whether one is set.
