Definition: Grade S operational adaptation

A $\mathsf{Grade}\mathsf{S}$ adaptation in this paper consists of:

1. a prescribed Lorentzian background and a regular local rod chart;

2. a finite named experiment, specified accessible algebras, a complete instruction tree, and an explicit resource ledger;

3. a complete destructive clock instrument and a declared record, rod, and causal dictionary;

4. exact evaluation of the frozen finite response certificate, together with a stated operational realization of its numerical signature;

5. a reference-preserving transport channel and a proof that all admitted scheduled dependencies are causally embedded.

The contract does not require the geometry, the response prescription, or the contact class to be reconstructed from records.
