The situation
Search returns nothing for the creator "Chloé" when someone types "Chloe", and two captions that look identical on screen are treated as different. Jax has a creator asking why they're "invisible in search".

What you leave with
You built the lab's accent-insensitive search key while preserving each original name. You also normalised canonically equivalent sort keys. Matching policy can create collisions, and equal sort keys still need a tie-breaker when source order varies.
