Built to Break: Revised — Closing the Open Test

Built to Break documents, in real time and without laterrevision of its original chapters, the construction of a physicalpostulate for wave-function collapse - the claim that objectivecollapse is triggered by real, thermodynamic energy dissipation betweena quantum system and its environment, not by an act of observation orconsciousness - alongside the actual process of building, breaking, and rebuilding the mathematics behind it.Chapter 3 documents a twenty-six-order-of-magnitude arithmetic error, found and corrected in full technical detail. Chapter 8, new to thisrevised edition, goes further: it takes the postulate's ownfalsification table and applies it to a real, independently publishedexperiment - Hornberger et al. (2003), collisional decoherence inmatter-wave interferometry - with no free parameters chosen to make itwork. The result does not favor the postulate's central distinguishingclaim, and the book says so plainly.This is not a claim to have solved the measurement problem. It is acandidate solution - compared directly and honestly against GRW, CSL, and Diósi-Penrose - built carefully enough to be tested, and specificenough to say exactly where it turned out to fail.Written in active, documented collaboration with an AI system, Built to Break is also a record of what disciplinedverification looks like when the mathematics is checked line by line, including the parts that don't survive contact with data.
