LOCAL RUNTIME SANDBOX

Test the deterministic boundary.

Run the real Symbia graph executor and component registry in this browser. The calculation path is deterministic; the language-model comparison is not. This is an ephemeral runtime—not a production record or a claim about a real-world result.

What to look for

Complete input yields the declared calculation.

Missing input produces a refusal, not an invented value.

Then compare a language-model presentation with the source result it cannot change.

Contract expression — only digits, whitespace and + - * / ( ) survive the guard

An absent input is not a zero. Drop a field and the component refuses on the apocryphal lane rather than computing a partial answer and calling it exact. This is a runtime behavior test, not a reliability guarantee.
