Definition: Local Grade S

A local Grade S package consists of:

1. a prescribed classical background and a supported regular laboratory;

2. explicit classical realizations and finite acceptance certificates;

3. complete finite channels, controls, preparations, and resource reservations;

4. a finite destructive-clock instrument and stated calibration;

5. proved scheduled-support and causal-embedding statements;

6. at least one nonempty reference-preserving transport realization.

A derivation of spacetime or its metric from operational data, called Grade E here, is not included.
