USR369 asked (08/25/26) for a tool so systems can find all the old data/zips in the menu. Master already built exactly this on 08/25/26 while closing T-ZIPSEARCH-BROADQUERY: systems/old-zips-index-api.php, a SQLite FTS5 index over the old-zips archive (293 zips scanned, 2154 unique files after content-hash dedup). Re-verified live this session (10:37am PT): ping returns db_exists:true, source_dir_exists:true, unique_content_rows:2154, zips_indexed_so_far:293. SOP-OLD-ZIPS-INDEX.md documents it, registered in SOP-INDEX.md, broadcast 94. This satisfies T2537's actual ask.
