-- Phase A: feedback tables re-namespaced into paliad.*.
-- Replaces docs/migrations/00{1,2,3}.sql which put them in public schema.
--
-- Old tables (public.patholo_link_suggestions, public.patholo_link_feedback,
-- public.checklisten_feedback, public.gerichte_feedback) continue to exist
-- and are still referenced by the current handlers via PostgREST.
--
-- Phase A creates the paliad versions fresh (no data copy) so the rest of
-- the platform can adopt them. A follow-on phase (P1 handler refactor) will:
--   (1) swap handlers from PostgREST to the direct DB connection,
--   (2) copy any meaningful rows from the public tables,
--   (3) drop the public tables and this duplication.
--
-- This is flagged in the Phase A completion report.
