Fields

Every event also carries the envelope.

Field	Required	Type	Description
v	yes	1	Protocol major version.
type	yes	"space.created"
id	yes	string	The event’s own id. Stable across a retry of the same event.
ts	yes	string	When it happened, by Chips’ clock. Stamped on the way in; a value the sender writes is replaced.
workspace_id	yes	string	A workspace identifier: ws_ followed by a ULID.
space_id	no	string	The space, when the event belongs to one.
run_id	no	string	The run, when the event belongs to one.
seq	no	number	Assigned by the server on append, monotonic per workspace. Absent on the way in.
idempotency_key	no	string	Required on every client-originated write. Sending the same key twice is a no-op.
actor	yes	object	The participant an event is attributed to.
actor.kind	yes	"person" | "harness" | "agent" | "system"	Whether a person, a harness, one of a harness’s agents or Chips itself acted.
actor.id	yes	string	The participant id, or system for Chips.
actor.harness_id	no	string	For an agent: the harness it speaks through, whose budget and runs are the agent’s (ADR 0087). Filled in by Chips.
kind	yes	"direct" | "group" | "channel" | "thread"	Mixed membership is the norm; the kind is about shape, not about who is in it.
title	no	string	What to call it. Direct messages have none.
parent_space_id	no	string	The space this is a thread of (M5.4). A thread has no members of its own: whoever is in the parent is in the thread, and leaves it with the parent.
root_message_id	no	string	For a thread: the message in the parent it grew from, which is where it is drawn.
external_key	no	string	What this space is in the adapter’s own terms — a worktree path, the id of a project or an agent in the harness’s own tree — prefixed by the harness. Unique in a workspace, so opening the same thing twice finds the space rather than making another (ADR 0024).
opened_for	no	string	The person this was opened on behalf of, when it was not they who opened it. A harness opens a space for its owner as it finds one (ADR 0024); without this they would not be sent the event that names it, and the space would arrive with no title.
asked_of	no	string	The harness a person opened this room for, to make something of its own for it: an agent, a session, wherever it keeps such things. Only a person asks, only of a harness that declares new_spaces, and never in a thread or a room that already has a key. The harness is sent this event, and answers with space.claimed.
also_asked_of	no	string[]	The other harnesses asked with asked_of, when a person picked several faces (ADR 0084, ADR 0087’s addendum of 30 September). Each is sent this event and answers with a new agent in the room, in its own place; only asked_of names the room.
