E.9.DA:4.3 - Ordinal coordinate scale and effective floor

Value	Label	Meaning for a `DRR` decision-adequacy coordinate
0	`absent`	The coordinate is not expressed for the declared authoring use.
1	`namedOnly`	The coordinate is named or implied, but cannot carry decision reliance.
2	`partiallyExpressedForDeclaredUse`	The coordinate is present but incomplete, fragile, or too narrow.
3	`sufficientlyExpressedForDeclaredUse`	The coordinate can carry the declared authoring use, with limits visible.
4	`wellExpressedForDeclaredUse`	The coordinate is clearly expressed with direct evidence and boundary protection.
5	`exceptionallyExpressedForDeclaredUse`	The coordinate is exceptionally expressed across reinforcing loci and cases without hiding cost or neighbour loss.

When a complete reusable coordinate evaluation is produced, each ordinal value is a content-evaluation claim about the exact checked DRR under the declared use and window. In an ordinary bounded review, the same scale may guide judgement without materializing a measure, Work record, result episteme, assurance, acceptance, or reward.

The default effective floor is 3 sufficientlyExpressedForDeclaredUse for every required E.9.DA coordinate. The required authoring use comes from the review request, an accepted decision, or an E.22 question frame; the E.9.DA default supplies the floor when that source did not raise one before evaluation. A source may raise the whole floor or named coordinate floors before evidence is judged. The evaluator may not lower a floor, narrow the use or selected loci, or shorten the qualification window after seeing the result in order to make the DRR admissible. A diagnostic use with a lower target may report values, but it cannot yield admissibleForDeclaredAuthoringUse.
