Empirical Standards for the Persistence Collapse Sector of Conditional Unlocking Fields: Version 5 Benchmark

This record contains the locked V5 empirical standards benchmark for the persistence collapse sector of Conditional Unlocking Fields (CUF), together with its preregistration, frozen production harness, and archived output package. The benchmark was designed to answer a narrower question than “is CUF as a whole correct”: whether the empirical measurement layer for the persistence collapse sector is standards ready under a locked protocol, with explicit classification of canonical candidate, standardizable, and exploratory quantities, adversarial null testing, and observable tier validation. The preregistration states this scope explicitly, distinguishes operational definitions from CUF interpretation, and declares the deviations from full canonical CUF that remain in force, including first exit survival in place of ledger projection, control parameter interpolation in place of canonical k*, absence of Gb × GW invariance certification, scalar corridor viability, and transformed tier perturbation on the primary input coordinate rather than full observable inversion. The V5 benchmark extends prior CUF persistence collapse work by testing five benchmark systems together with one adversarial null control under a preregistered standards framework. Its goal is not to claim full CUF certification, but to determine which empirical quantities and system classes are stable enough to support a standards governed persistence collapse layer. The accompanying paper reports that the strongest standards positive results occur in systems with clean integrable to chaotic transitions, that observable invariance is strong for the clearest positive cases, that the standard map reveals a genuine observable selection constraint, that Arnold cat functions as a protocol null under the block-mean corridor operationalization, and that the adversarial null is distinguishable by broad boundary crossing rather than a sharp collapse signature. The paper also states explicitly what was strengthened in the persistence collapse sector, what remains open, and what is deferred to later versions. This upload should therefore be read as a standards governed empirical research package for the CUF persistence collapse sector rather than as a claim of full canonical CUF execution. It preserves the final V5 paper, the locked preregistration, the frozen benchmark harness, and the archived outputs needed to inspect, verify, and reproduce the run.
