Artifact schema debug log gains an assets_source flag; an endpoints killswitch check was removed

What

The debug log line generated when Claude Code builds the input schema for the Artifact tool now includes an assets_source value, and a frozenHotUpdate value is now also captured. Separately, the check for the "endpoints" capability flag no longer excludes the case where the endpoints feature flag is set; that exclusion clause was removed.

Why

The added logging gives more visibility into how the Artifact tool's schema is built, while removing the endpoints exclusion changes when the endpoints capability is considered active.

The writer flagged doubtThe finding does not explain what the removed endpoints exclusion controlled in practice or what effect its removal has.
