This is an example report generated by
scope-tracer
from the
OrderProcessingDemo
— a nested e-commerce order pipeline where one order is declined by a fraud check.
It shows nested scopes, cancellation propagation, and critical-path highlighting. No install needed — this file is
self-contained HTML generated straight from a JFR recording.

README to generate your own.
