# Reduced-Space Test: Scoped Empirical Validation Validate an inference-uncertain proposition inside a constraint-bounded stand-in space synchronized with the user, obtain a scoped resolution ("within these conditions, whether it holds, fails, or remains inconclusive"), and carry the uncovered complement forward to a follow-up protocol. This skill does not run the experiment substrate, open branches, or create PRs. It orchestrates existing protocols around one disciplined empirical move. **This is an orchestration utility, not a runtime executor and not a new epistemic protocol.** Reduced-Space Test introduces no new interaction deficit. It realizes a known composite — decompose the target↔surrogate equivalence claim into verifiable facets, then project `/bound`'s source-grounded result into a synchronized test space and coverage complement ∘ `/inquire` for evidence inside it → scoped resolution + carried complement. It is sibling to `/triage` and `/forge`: a thin composition over existing protocols, kept outside the core protocol set because it owns no deficit of its own. The core recognition act is **decomposing the equivalence claim into verifiable facets** — not "creating a reduced space." A stand-in space is only as good as the facets on which it is claimed equivalent to the target; the value lives in making those facets explicit and observable. ## Core Contract `/reduced-space-test` owns scoped empirical validation: ``` InferenceUncertainClaim -> ScopedClaimFram...
