Function rest_bind_capability_facts_for_source 

pub fn rest_bind_capability_facts_for_source(
    source: &FbxScaleSource,
) -> Result<ScaleCapabilityFacts, String>

Project the narrow FBX rest/bind subset from one captured source.

Shared construct/resource coverage is checked before the older operation-specific inventory. This prevents a truncated positive-only raw projection from being treated as proof of absence.

Errors

Returns a stable refusal naming each incomplete shared-raw coverage domain, unsupported construct row, semantic status, or inventory counter that prevents proof of the selected domain.
