Calibration, Linearity, and Records

Inspect which assumptions transport amplitudes, which records determine a value, and what does not select one outcome.

Definitions and assumptions

Scope and physical limitations

Finite-basis maps on initially ready apparatus and communication registers, within one specified description. This is not arbitrary-state cloning, a derivation of collapse or the Born rule, or a model of consciousness.

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.

Unsubmitted text stays in this tab when navigating declarations, but is not saved across reloads.

Import merges local entries without overwriting them.
