A.11:7 - Rationale

Ontological parsimony preserves FPF’s ability to handle many domains without turning every local distinction into a root object. The pattern follows the same discipline used by E.24.UK: recover the governed object first, then decide whether a new durable value is needed. Using an existing governed expression is a successful result, not a failure to mint a kind.

The practical criterion is not abstract minimalism. A candidate earns a positive parsimony finding only when users gain a claim, comparison, repair, stop condition, reliance condition, or boundary they cannot recover by composition without material loss. Admission still requires its complete governing test. That keeps parsimony tied to FPF’s work-facing purpose rather than to a taste for small vocabularies.
