T01-T03 are done and T05-T08 were already handed to RMGR-WP-0004. T04's
gates (RMGR-WP-0004-T06, STATE-WP-0079-T04) remain open, and the task
always specified that removal land inside the 0079 strangler rather than
as an isolated breaking change. Cancel it here with a pointer, record the
inherited residual in 0079-T04, and mark the workplan finished.
