# LSI-PSD-10 v2.0 Expanded Edition

Topic: Proof-Space Non-Conclusion Principle.

The paper establishes the epistemic firewall for the LSI-PSD series. It distinguishes observations, diagnostic hypotheses, formal route-family no-go results, and mathematical verdict certificates. It also defines a verdict ladder, certificate-matching rules, and an epistemic type system for AI long-horizon mathematical research.
