The assigner's bundle runs in a runtime of its own on its own account and serves the first-view tools placement, seat-holders and wants, each answering only the callers its manifest writes (ADR 0621 §1-§2), and the six read tools of design 25 § 12.2. The process says each change of those six states on the family assigner-views beside placement in its old streams section (ADR 0619 §2, ADR 0615 §5); a waiter on put never wakes on it. Issue 1966.
