API Reference

assertDirtyPrecedesTerminalData()

Assert that observed tier-3 settlements (DATA/RESOLVED) are preceded by DIRTY.

This encodes R-dirty-before-data for wave-framed subscriber traces. The leading START push-on-subscribe/replay handshake wave is exempt because cached/replay DATA is advertised to a new subscriber without opening a propagation wave.
