-      The last file of a second mirror that sat beside tests/test_litellm and ran nowhere. Its
-      other 33 files landed in the real mirror during August 2026, 30 as moves and 3 by merging

-      its live twin was rewritten from 1268 lines to 9434, and of the 19 tests here 5 have no
-      counterpart while 25 assertions fail against today's code, so what survives that rewrite
-      is a judgement about the endpoints, not a merge. Revisit by deciding which of the five

       vendor vector stores, so assigning them needs a per-file decision
