Four real control flows from the harness and the jobs around it. Pick a path and the lit route shows what happens at each step, and where it ends.
How to read this: steps run left to right, and a branch drops down when a decision goes the other way. The lit path is the one you picked; numbers match the step list, and clicking any node explains it with its source file.
Every node, branch and cadence is read from the cited files as of 2026-10-20; nothing here is live.
