Each AP-enabled app (blog, market, events, federation) now serves its own webfinger, actor profile, inbox, outbox, and followers endpoints. Per-app actors are virtual projections of the same ActorProfile/keypair, scoped by APFollower.app_domain and APActivity.origin_app. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
