+--   (1) Fix malformed double-prefixed URLs (a scraper concatenated the base host in
+--       front of an already-absolute URL, e.g. "https://www.mouser.dehttps://www.mouser.de/…").
+--       503 rows affected (details_source_url 373, product_page_url 83, image_url 47).
+--       These cannot be fetched, so they block any enrichment run.
+--   (2) A guard so the ingest bug cannot re-introduce them.
+--   (3) v_datasheet_enrichment_worklist — the pipeline's input: every transceiver/switch
+--       that needs a field filled from source, with its best source URL + type.
+-- Idempotent; safe to re-run. The regex only matches a second scheme that appears
+-- BEFORE the first path slash, so legitimate URLs with an encoded URL in the query string
+-- (…?url=https://…) are never touched.
