+No task is a `wait`: the plan is parked as `backlog`, not `blocked`, per
+`docs/threephoenix-implementation-gate.md`. It opens (`ready`) when an operator
+records the dated preflight artifact (three reef members, network and custody
+decisions, backups, approving operator). That is a human gate on the plan, not on
+a single task; until then only source-only design and tooling is allowed.
