 - [ ] Record dataset size, clip length, hardware, operating system, network region, date, provider plan, and warm/cold conditions.
 - [ ] Add confidence intervals or an explicit limitation explaining why the benchmark is too small for them.
 - [x] Implement a fourth local constellation-map/hash-pair backend over a small library, with an index builder and benchmark integration. Real-world accuracy and speed comparison remain open until the corpus is recorded.
-- [ ] Replace `Test set accuracy | X / Y songs matched correctly` in `readme.md` with generated, reviewable results.
