space.erased

A space was erased from the server by a person: what was said in it, its files and its search entries are gone for everyone. Only this line stays, naming which and by whom.

Direction: Chips → the log
Sent by: Chips only; refused from a client
Requires a run: no
Schema: space.erased.json

Fields

Every event also carries the envelope.

Field	Required	Type	Description
v	yes	1	Protocol major version.
type	yes	"space.erased"
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.
erased	yes	string[]	The space, and every thread of it, in that order. Each device forgets them.
spent	no	object[]	What the room cost, per harness, so an erase takes the words and leaves the spend: a budget is not topped up by erasing where it went. Written by Chips.
spent[].harness_id	yes	string	Whose account the room’s cost was on.
spent[].usd	yes	number	What the room had cost that harness, in US dollars.
