Reply

A post added to an existing conversation or event by any member who can view it. Replies extend a conversation or event's discussion. They do not create new threads or branches.

Allowed:

• reply to a conversation
• reply to an event
• event reply
• conversation reply

Forbidden:

• comment (connotes a secondary or subordinate voice; replies are first-class)
• response (acceptable in error copy; not a domain noun)
• answer (implies Q&A structure)
• post (ambiguous with social feed semantics)
• message (a reply is not the same as an open message)
• Social DM (a reply is not private)

Notes:

• The API action for posting a reply is POST /social/conversations/{id}/messages or POST /social/events/{id}/messages. The path segment /messages is a legacy payload route segment, not the product term — the user action is always called a reply.
• Replying to a public conversation automatically adds the replier as a participant.
