JSON Schema validation is the dominant cost at scale and scales linearly with entity count; every other stage is seconds. This is direct evidence for the Annex F reference-tooling and dictionary questions: the wire format is not the bottleneck, the validator is."

No result was added, removed, or altered; tools/validate_registry.py re-derives this normalization from the vendored statement on every CI run and fails if the two diverge. The date is the v0.2 publication date. The run environment was not recorded by the v0.2 run and is not invented here."
