Fields

Every event also carries the envelope.

Field	Required	Type	Description

type	yes	"message.handed"

ts	yes	string	When it happened, by Chips’ clock. Stamped on the way in; a value the sender writes is replaced.

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.

message_id	yes	string	The message, as message.new named it.
agent_id	yes	string	Who it is handed to.
