Iteration 85 โ€” B-06 Opens: GW-CPA Passes the Exam NEW BATCH ยท EVERY BOUNDARY FED ยท EXAM PASS

In plain words: with the fragile-boundary batch closed, the queue turned to the deepest remaining deficit: the CONDITIONAL boundary's DECLARATION layer โ€” the formal machinery for saying "this feature works in THESE named regimes" with controlled error rates. Sixty draft declarations await exactly this support. With this batch open, every boundary in the status machine has now received candidates โ€” full coverage, a campaign first. Its cheapest candidate is also its most on-point: the econometrics-native test of whether a feature's predictive advantage depends on the regime. Its exam passed on the first form, with the sharpest exactness test yet: fed the byte-twin and its original as competing forecasters, the loss difference was zero to the last bit at every timestep โ€” and the implementation correctly recognized the identical-forecasts case instead of dividing zero by zero. On the real question it was decisive: the intensity feature's predictive advantage IS regime-conditioned, at odds of fifteen million to one against chance. The batch-opening reasoning and one honest import correction are on the ledger.
