bd comment <id> "text" and bd comments <id> — threaded discussion attached to a bead, with --thread for reply structure.

Two details make this more than a comment box. First, authorship is recorded in the events journal: the actor column is stamped inside the mutating transaction, and “on a comment row it is the comment’s author” — so a multi-agent database can answer “which agent said this?” rather than just “what was said”. Second, comments are the payload of the messaging surface: a message-type bead with threading, an ephemeral lifecycle, and delegation via beads-mail turns the comment mechanism into agent-to-agent correspondence.

This is where a store starts to absorb something the process frameworks do in prose. mp-handoff compacts a conversation into a document; beads keeps the conversation attached to the work item it is about, permanently and per-actor.

Maps to no canonical SDLC stage.
