Artists only. Live: every artist lookup NotOnQ has handled, through the playground, the drop-in API or the Qloo harness, updating as it happens. Below it, a fixed benchmark run that measures what live traffic can't.

A fixed sample, so the numbers mean the same thing for everyone. It compares new artists with chart artists, and tests the stand-ins against Qloo's own answers, which live traffic can't. It used 303 Qloo calls; rerun with node --import tsx scripts/proof.mts.

Sample	Artists	Usable in Qloo	Unknown (G1)	Not in taste graph (G2)	Gap
Artists with a release in the last 14 days (ListenBrainz fresh releases, single-artist credits), seeded random sample	100	37	61	2	63%
Last.fm global top artists chart	100	96	3	1	4%

Fill (30 gap artists, open data and stand-ins only): sourced entity 100%, stand-ins 80%, popularity 33.3%, genres 26.7%, description 3.3%, image 0%.
Backtest (15 artists Qloo knows, each hidden): stand-ins alone recover 37.3% of Qloo's own top 20 "fans also like" (28.7% of the top 10).
G1: Qloo has no entity (MusicBrainz ID or exact name). G2: Qloo finds the entity but /v2/insights rejects it as a signal.
