Path Parameters
Header Parameters
string·min 43·max 43Session-bound CSRF token. It must exactly match the
__Host-assign_csrf cookie sent with the request.
Request Body
application/jsonstring | null·min 1·max 64Optional stable Workspace Milestone stage ID. Must select an active stage whose category agrees with status; null clears the selection. An explicit legacy status update without stage_id clears a custom selection.
string <uuid>Opaque Assign-owned UUIDv7 identifier. Clients must not derive meaning from it.
Responses
stringQuoted decimal optimistic-concurrency version.
objectMaterialized lifecycle policy of the entity's current status. Compare
stage_revision and definition_revision for staleness; behaviors
is the complete set for the entity kind, so clients never infer policy
from names or categories. Absent when the selection has no lifecycle
status. Resolved for a whole page with one batch lookup. Project list
rows carry identities and revisions only: stage_name and behaviors
are omitted there and returned by Project detail and the lifecycle
definition list.

string | null·max 19Stable Project-local positive signed-64-bit number as canonical decimal text (maximum 9223372036854775807), independent of Task numbering and rank. Null or absent while a historical Milestone awaits reference backfill; never derive it client-side.
string | null·max 29Canonical uppercase Project-key Milestone reference, for example FRS-M1. Stable across rename, reorder and archive/restore. Null or absent with milestone_number during historical backfill. UUID selectors and foreign keys remain authoritative; knowing a code grants no access.
