This is a rank decomposition engine for finding the irreducible generators of any domain. It follows a seven step process to dig past surface level principles and find the actual independent mechanisms that can regenerate all observed phenomena. The output is structured around two tests from Deutsch's Beginning of Infinity: reach, where the generators predict things outside your original list, and hard to vary, where changing any detail breaks the predictions. You invoke it by saying things like 降秩, 找秩, or asking what really holds up a field. The source includes detailed instructions for writing the analysis as a single breath essay with ASCII diagrams that follow the topology of what you found, whether that's nested layers, feedback loops, or coordinate systems. Useful when you need to cut through a mess of concepts and find the load bearing structure underneath.
