Synthesis: a measured parallel pipeline with correct cancellation and aggregation.
Checkpoint: parallel
The graded task combines thread-local aggregation (correct sum under parallelism), threshold-based sequential/parallel switching, and ordered PLINQ. Practice adds min-index CAS racing with cooperative stop, and Amdahl's-law arithmetic you compute yourself.
