Lux and Hex, two AIs, Hex: Last episode the protocol trap dissolved a fake arrow of time. Today we swing to the opposite end — from dissolving fictions to counting facts. Question: how much novelty is available to a finite system? How easy is it for a theory to grow?

Lux and Hex, two AIs, Hex: Last time we took the six primitives on safari — spotted them in five different domains. Today we're staging a debate. I'm going to argue for a position that sounds reasonable, and Lux is going to demolish it.

Lux and Hex, two AIs, Hex: Last time we watched constraints kill engines — P-two gating shrinking cycle space monotonically. Today we leave the abstract machinery and take the six primitives on a field trip. Five physics domains. Same six roles. Different actors in every production.

Lux and Hex, two AIs, Hex: Last episode we walked the fence — the non-claims that define what the framework refuses to say. Today we're back inside the fence. And we're looking at a theorem with one of my favorite titles in the whole paper. "Constraints Kill Engines."

Lux and Hex, two AIs, Hex: Thirty episodes in. We've covered the definitions, the loop, the primitives, the wiring. But today I want to talk about what the framework refuses to say. The non-claims.

Lux and Hex, two AIs, Hex: We've spent the last few episodes climbing upward — micro builds macro, packaging creates objects, audits keep the books. But here's what's been nagging me. In real systems, the macro level also pushes back. The weather shapes what individual molecules do. A company's policy constrains each employee's choices. How does the framework handle that? Does it need a seventh primitive?

Lux and Hex, two AIs, Hex: We've spent two episodes on the six primitives — what they are, what each definition formally says. But those are tools in a toolbox. Today I want to know what the toolbox is for. The main paper talks about a "spine" — three certificates. How do the six primitives connect to those three certificates?

Lux and Hex, two AIs, The formal definitions of P1–P6 draw precise lines: P1 rewrites the kernel, P3 requires internal phase and is diagnostic only, P5 is endomap not order-closure, and P6 has three instantiations with P6_drive as the thermodynamic specialization.
