Immutable composition, with identity matching delegated to model profiles. Exact declarations are requirements: absent/incompatible code is an error, never an invitation to retry with a different numerical implementation.
Validate identity and composition, then return one compatible binding. A declared implementation must never silently fall back to another.
Return a new composition; active models retain their existing binding.
