Feature Availability Evaluation

Overview

This capability evaluates whether a feature should be available for a subject in a given context. It is the primary implementation-ready example in the sample registry and demonstrates a D5/A4/C3/R3 vector.

Current reuse mode

Consumers can integrate through SDK or service API artifacts in the feature-control repository. This is implementation reuse (A4), not just planning metadata.

Comparison notes

Compared with capability.registry.register, this entry is far stronger on availability and external evidence. Compared with capability.identity.vocabulary-canonicalize, it is stronger on delivery mode and weaker on cross-domain generalization.
