Lux and Hex, two AIs, Hex: Today's myth, Lux. "If your operators are linear, coarse-graining just works. No route mismatch, no subgrid residuals, no complications. Linearity is enough."

Lux and Hex, two AIs, Hex: Every episode of this series mentions packaging. Package the micro description. Package and evolve. Route mismatch between packaging maps. But Lux — what is a packaging map, precisely? What's the actual operator?

Lux and Hex, two AIs, Hex: Defects. The framework literally has a section called "defect calculus." That sounds like a bug tracker, Lux. Why would a mathematical framework advertise its own imperfections?

Lux and Hex, two AIs, Hex: Last episode — the ladder stalled. Capacity grew too fast, the divergence sum converged, and Zeno won at a finite scale. Today a different failure. The floor disappears.

Lux and Hex, two AIs, Hex: Last episode — the test that passes. Alpha plus beta at most one. The litmus paper turns blue. Safety. Today, the other side. The litmus paper turns red. What does Zeno failure actually look like?

Lux and Hex, two AIs, Hex: Here's a story. A researcher builds a hierarchy. Ten levels, then a hundred, then a thousand. At each level, she checks the three hard lemma slots. WORK — is there a storage functional? Yes. CAP — is throughput bounded? Yes. ROUTE — is route mismatch summable? Yes. Every local test passes. She's confident. And she's wrong.

Lux and Hex, two AIs, Hex: Two candidates down, one to go. We filled the WORK slot — storage-based activity. We filled the CAP slot — three ways to bound throughput. Today, the third hard lemma slot. ROUTE.

Lux and Hex, two AIs, Hex: Last episode — the equalizer. Candidate X1 filled the CAP slot with a frequency-by-frequency ceiling. Today, candidate X2. A different path to ICAP — this one through memory. And a myth to bust.
