but I presume calling STAT is akin to observing the system, whereupon the state collapses into one single result.

This :D

Not just the cancellation, but whole order lifetime entails dealing with fuzzy quantum phenomena, one has to wait after placing the order it till it can be observed in STAT. I think I have seen balances updated first, then in next stat appeared the transaction itself (although this happens very rarely). Oh and entangled pairs of phantom orders/transactions, too. Only thing missing so far is is superposition of states , but I presume calling STAT is akin to observing the system, whereupon the state collapses into one single result. Maybe MPEx should offer end-to-end quantum access to the engine, enabling users to submit orders with precisely defined wavefunction, instead of pretending above behavior is a bug and trying to fix it in vain or rationalize it backwardly.
