When golem15.chat is active, Boot registers the context alias bm (id 1) on its registry. Membership is the user group jz.bm.chat.group (default studenci); CanOverseeChats is always false, so nobody reads other people's DMs or edits their messages; the broadcast channel is chat:context:1, never empty. GET /_bm/api/v1/chat answers the caller's membership behind jwt.auth and the per-user bucket jz.bm.chat (240 a minute). The chat config block (group, moderator_group, max_upload_bytes, max_embeds) is added. jz.bm still Requires only golem15.user; all chat wiring is gated by HasPlugin.
