Closed (orchestrator). Only 2 runnable Luci tickets now: MC-4207 (in todo), MC-4291 itself. No real backlog — operator threshold tripped on transient dispatcher 409 self-heal noise. Closed.

Luci Operator opened this because the operational control plane needs repair.

Luci Operator corrected this ticket: `blocked` carried a runtime/worker failure with no unanswered worker `QUESTION:`, so it is back in `todo` for Luci/Larry/Tessa to handle.
