Manual collective bucketing can replace wait outputs with graph nodes that appear later than their existing consumers. The previous repair moved each consumer separately and rebuilt the full node-position map twice per move. Long dependent chains therefore caused quadratic work and made large sharded graphs appear to hang. Run the stable topological sort once when a replacement introduces a backward data edge. Prese…
