# What does this implement/fix?
Albums published on a band's page by a different performer (Mortaja on
audiophob, The Green Arrows on Analog Africa) used to be filed under the
page owner. They now get a synthetic artist ID
`{band_id}:{performer_slug}` — scoped per band page so cross-page
same-name performers stay distinct. Synthetic IDs that match the
page-owner's own slug short-circuit back to the real band on resolve,
collapsing any search-time drift before it can persist.
