+-- Intentionally a no-op migration.
+--
+-- The audiobooks absorption design spec assumed silo needed to add a
+-- 'kind' column to a hypothetical media_libraries table to discriminate
+-- between movies/tv/audiobooks/podcasts at the library level. Discovery
+-- found that the actual table is media_folders and it already has a
+-- type text NOT NULL column carrying that role (existing values:
+-- 'movies', 'series', 'mixed').
+--
+-- There is no CHECK constraint or enum on media_folders.type, so adding
+-- 'audiobooks' or 'podcasts' as future values requires no DDL — the
+-- scanner branches in sub-plan 2 will simply read those values from
+-- media_folders.type the same way they do for 'movies' and 'series'.
+--
+-- This migration is preserved as a numbered no-op so the audit trail
+-- shows the decision rather than leaving a numbering gap. The matching
+-- .down.sql is also a no-op.
