+-- 041: Add index on thesis_languages(language_id) for contenus page performance.
+--
+-- The contenus page queries getAllLanguagesWithCount() and searchLanguages() join
+-- languages → thesis_languages on language_id.  SQLite's PRIMARY KEY on
+-- (thesis_id, language_id) cannot optimize a lookup by language_id alone, so
+-- it builds an AUTOMATIC COVERING INDEX per query.  This persisted index
+-- removes that overhead.
+--
+-- Also adds a covering index on tags(deleted_at, name) to accelerate
+-- getAllTagsWithCount() and searchTags() ORDER BY clauses (avoiding temp B-tree).
+
+CREATE INDEX IF NOT EXISTS idx_thesis_languages_language
+    ON thesis_languages(language_id);
+
+CREATE INDEX IF NOT EXISTS idx_tags_deleted_name
+    ON tags(deleted_at, name);
