Philosophy of science examines cross-level explanation, identifying constraints and behaviors, implying limits on interdisciplinary synthesis.

The aim is to dissect the fidelity of explanations across different scientific levels and identify patterns of decay in specification.
Introduces a distinction between constraint and specification components of explanations.
Analyzes conservation laws, thermodynamic bounds, and specifies conditions for fidelity decay across levels.
Derives exponential decay from information identities rather than from channel assumptions.
Identifies that only specification components decay exponentially while constraints remain robust across levels.
Establishes that explanatory loss is independent of where the chain starts in cross-level analysis.
Demonstrates a ceiling on synthesis that is equivalent to the floor of reduction, with implications for epistemic confidence.
