Definition: Record-only determination

An independent operational completion of a fixed record appends:

1. a finite code $C$ and an isometry $W:C\to R\otimes B$;

2. specified accessible and complete complementary outputs;

3. where relevant, a fixed preparation and sequential unitaries.

No correspondence theorem between these appended data and the sector record is presumed.

A quantity is determined by the record alone only if it has the same value in every such completion with the named code and output conventions fixed.
