 that middle transform doesn't need the barrier. Rewrite as a pipeline with the transform inside a stage. When in doubt: pipeline.
 
-Concurrent agent() calls are capped at min(16, cpu cores - 2) per workflow — excess calls queue and run as slots free up. You can still pass 100 items to parallel()/pipeline() and they all complete; only ~10 run at any moment. Total agent count across a workflow's lifetime is capped at 1000 — a runaway-loop backstop set far above any real workflow.

A single parallel()/pipeline() call accepts at most 4096 items; passing more is an explicit error, not a silent truncation.
 
 The canonical multi-stage pattern — pipeline by default, each dimension verifies as soon as its review completes:
