+Disabled, operator-triggered paid proof for SECRETS-WP-0009-T03 /
+GLAS-WP-0012-T04 / HFACT-WP-0001-T04. It emits exactly one bounded task into the

+`rein-aharness metered-once` owner claims it: the label `hfact-metered` is not
+claimed by the `automated` claim loop. The far-future timestamp is only a valid
+definition shape; disabled status prevents any schedule.
