Structural Archaeology

This a conceptual sketch of historical cases analyzed through structural invariants and diagnostics to show how explanatory configurations change. A configuration is a stabilized arrangement of identity criteria, boundary placement, dependency structure, and ordering assumptions that determines what explanations are even admissible in a given historical context. A configuration determines what counts as evidence, what counts as a cause, what questions can be asked, and what explanations are possible. History is a sequence of configuration transitions in which different eras organize the four invariants differently, and those arrangements in turn shape which diagnostics become active, meaningful, and authoritative within that explanatory system.
