Historical Constraint Fidelity: Causal Residue, Constraint Inheritance, and the Geometry of Future Reconstruction

Historical Constraint Fidelity: Causal Residue, Constraint Inheritance, and the Geometry of Future Reconstruction This paper develops Historical Constraint Fidelity (HCF) as a descriptive systems framework for examining how surviving historical constraints shape later reconstruction and, through that reconstruction, the future options that observers regard as reachable, permissible, or justified. The framework begins from a strict non-collapse rule: E≠T≠D≠Ao≠Ho≠FoE \neq T \neq D \neq A_o \neq H_o \neq F_o where event, evidentiary trace, durable record, accessible evidence, historical reconstruction, and future-accessible geometry are treated as distinct objects. Three bounded contributions are developed around that separation. Causal Residue denotes surviving consequences of an event whether or not those consequences have yet been recognized as evidence. This preserves the distinction between an event’s continuing effects and the documentary record of that event. Constraint Poisoning describes a trans-observer failure mode in which inaccurate, provenance-damaged, selectively curated, or structurally misleading material persists inside the inherited record set and constrains later reconstruction toward an unsupported history. Criterion-level corrigibility places the rules governing historical reconstruction inside the correction boundary. A reconstruction may converge under a given criterion without validating that criterion itself; historical reasoning therefore remains corrigible only when the standards used to admit, rank, and reject evidence can also be revised. The paper also develops a layered account of how reconstruction may affect later choice: Ho→Foperceived/permittedH_o \rightarrow F_o^{\text{perceived/permitted}} while explicitly refusing to equate changes in perceived or permitted futures with changes in what is materially reachable. The framework is deliberately null-driven. Its distinctiveness is tested against established work in historiography, archival science, reconstructive memory, source criticism, information theory, belief revision, historical analogy in decision-making, path dependence, event-sourced systems, representational compression, and observer-frame effects. If those established accounts fully absorb the proposed remainder, translation or retirement is treated as a successful scientific outcome. The paper is explicitly non-clinical, non-adjudicative, and non-operational. It does not authorize retrospective diagnosis or personality typing of historical actors, does not adjudicate named historical controversies, and does not introduce a new Accessibility Geometry variable or Sovereign Witnessing coordinate. Its governing proposition is: Historical manipulation succeeds not by changing the past, but by changing which constraints survive into the future. Its counterweight is: The event may remain causally encoded without remaining recoverable.
