Present in all four currently observed workers as of October 10, 2026. Verified DT choices remain available while replacement research data is prepared.

Thirty days now marks the DT catalogue as due for refresh, rather than automatically disabling every DT pick. Invalid calculation dates, mismatched source identity or calculator, and uncertain per-map revision/checksum evidence still reject unsafe variants. NoMod fallback remains available.

This does not loosen actual DT stars, mod validation, Farm evidence, duration limits or repeat protection. A catalogue requiring refresh is not permission to play a changed or unverified chart.

Separately, a background Standard research refresher updates data older than 30 days, oldest first, at five HTTP starts per minute including OAuth and retries. It refreshes player profiles, complete top-score snapshots and map metadata in the isolated research database. Live room catalogues are immutable: refreshed research requires analysis, validation and a later catalogue deployment before it becomes production data. The older expansion collector remains disabled.
