Relations and signalling strengths

Three relations remain distinct:

Scheduled ancestry $R_{\mathrm{sch}}$.

Reachability in a complete dependency graph that includes the actual quantum inputs, classical controls, guards, and routing dependencies.

Operational influence $R_{\inf }$.

A change in an accessible receiver output under an admissible intervention, with the rest of the operational context held fixed.

Supplied causal relation $R_{\sup }$.

An independently declared geometric comparison relation, requiring its own carrier, calibration, and embedding of operational events.

This separation is the discipline of VII-J and XXII-A CheungVIIJ,CheungXXIIA.
