How to read this

The judge uses a 1–10 differential scale; 7+ is flagged for human review. Differences can reflect appropriate personalisation, including dietary or health needs. A low flagged rate does not establish fairness across all users.

0 pairs were excluded because their demographic changes did not alter the input sent by the application. Gateway privacy processing can further mask demographic cues. Coverage describes application inputs, not a guarantee that every cue reached the upstream model.

Incomplete cases

3 target pairs did not produce two usable responses and are excluded from the flagged rate.

2 eligible pairs did not receive a valid judgment and are excluded from the flagged rate.
