// wsMessageEdited / wsMessageDeleted are the downstream event types of the D3
// history writes: a message's content was edited, or a message was removed. Both
// reuse the wsEvent envelope and the same all-connections fan-out as
// `message_persisted` — the hub has no per-session subscription, so the frame
// carries SessionID and a client filters it by its active session, exactly as it
// does for message_persisted.

	wsMessageEdited  = "message_edited"

// broadcastMessageEdited fans a content edit out to every client as a
// `message_edited` frame whose data is the updated message DTO. The frame is a
// render-only sync: the edited content's single source of truth stays the history
// store, so a client that missed the frame converges again on its next read. The
// caller strips Thinking to match the message_persisted/replay contract.

// broadcastMessageDeleted fans a removal out to every client as a
// `message_deleted` frame carrying the removed id (plus the owning sessionId for
// client-side session filtering), so every browser of the account drops the row
// without a refresh. sessionID may be empty when the store could not report it;
// clients then fall back to the globally unique id.
