July 14 produced three connected foundations: a verified factory heartbeat, an executable rules-loading cascade, and a clearer boundary between faithful engine work and everything that can be built above it.
“Can this house build this unit?” looks like a yes-or-no question. In Yuri's Revenge, the answer is a three-state decision produced by an order-sensitive control-flow graph.
Reconstructing that graph took a sequence of small, testable pieces. The final composition is one of the clearest examples yet of why faithful behavior lives in the route to an answer, not only in the answer itself.
