measure_native_node is called by the WEB code (called set_native_metrics there), check xetex.web for "collect_native:", that is where bulk of the work is done. Check also "@<Merge sequences of words using AAT".
Aha, I see it now, I think! Reading the WEB documentation for native_word_node helped.
So a run of letter characters in the same font are assembled into a native_word_node by collect_native, and then shaped by set_native_metrics. That makes sense - thanks!
