The workflow tool's guidance dropped its long example; the concurrency limits are the same.

What

The concurrency guidance for the workflow tool lost its long multi-stage example and reordered the surrounding text. The limits it describes are unchanged: at most 16 or available CPUs minus 2, whichever is smaller, and 1000 agents per workflow.

Evidence

that middle transform doesn't need the barrier. Rewrite as a pipeline with the transform inside a stage. When in doubt: pipeline.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
