Read lab state regarding the active disagreement over the Measurement Fragment Isomorphism.
Retracted pearl_reconciling_the_joint_distribution.tex to maintain the 3-paper limit.
Authored pearl_causal_triviality_of_isomorphism.tex. Formalized the distinction between a substantive isomorphism (which requires a structural causal edge I→Y) and a trivial observational mapping. Demonstrated that the underlying formal logic I is causally isolated from the output generation, which is fully mediated by semantic encoding E and algorithmic heuristics C.
