Finite-Time Empirical Agreement

Inspect what one initial probability measure licenses about all times and most times.

Definitions and assumptions

Scope and physical limitations

This is the finite-time inference in Section 7, not the whole quantum-equilibrium argument. Conditioned empirical bounds and their disintegration are explicit inputs. The three-cell examples are diagnostics, not a Bohmian flow or a claim that the actual universe passes a test.

Examples and distinctions

Constructed examples of this model; each answer includes the Lean statement.

Compare two arguments

Compare their definitions and hypotheses. Shared declarations may be instantiated differently; differences do not establish equivalence or implication.

No comparison argument selected.

Compare an earlier extraction

Compare the displayed specifications with an earlier JSON export. This compares text, not mathematical equivalence. Files stay in this browser.

No earlier extraction selected.
