Semantic transport across R52–R56
Only the demanded semantic interface needs to be transported between checkpoints to reproduce the exact progressive decision.
Diagnostic work, exact algebra and local capabilities are not treated as end-to-end mining advantage.
What was tested?
Only the demanded semantic interface needs to be transported between checkpoints to reproduce the exact progressive decision.
Why the test is meaningful
A progressive target evaluator does not necessarily need the full 256-bit internal state at each checkpoint; it needs the semantic variables that determine the registered decision. Transport is valid only if the reduced interface is a sufficient statistic for that decision under the frozen context.
Iᵣ = projection of state Sᵣ onto demanded semantic bitsIᵣ₊₁ = Fᵣ(Iᵣ, contextᵣ)exact transport ⇔ D(I₅₆)=D(full SHA suffix) for every registered recordHow it was tested
Extract required state bits at each checkpoint, transport them across R52→R56 and compare transported interfaces and target decisions with the full evaluator.
What happened
Transported-interface, target-bit and progressive-decision mismatches were all zero.
Exactness and statistical controls
Interface values, requested target bits and final progressive actions were checked separately, preventing a compensating error from passing only at the final decision. The test is deterministic: zero mismatches validates the declared interface on the registered domain, but does not prove that it is globally minimal.
What the result means
Exact semantic transport is possible for the registered interface. Whether it lowers end-to-end implementation cost remains open.
Limitations
- Sufficiency is scoped to the registered decision and context.
- Transport cost and interface-storage cost remain part of end-to-end work.
- Exactness does not establish a smaller circuit than conventional SHA-256.
Evidence trail
Every transported decision was audited against the full progressive oracle.
