The Datum-Relative Conservation Principle (DRCP): A Boundary Criterion for Interpreting Apparent Loss and Gain

The Datum-Relative Conservation Principle (DRCP) formalises an interpretive constraint distinguishing true change from boundary-relative redistribution. The principle states that apparent loss or gain observed within a system may reflect transfer across observational or analytical boundaries rather than alteration of total quantity. DRCP establishes a domain-completeness condition requiring evaluation across the full admissible domain before classifying change as absolute. The construct functions as a non-interfering diagnostic operator applicable across scientific, logical, informational, and analytical contexts. It does not modify underlying models or laws but constrains interpretation, preventing misclassification of redistribution as destruction. The principle is falsifiable in principle and applies only to quantities governed by conservation relations or invariant totals.
