Spekkens' diagnosis and a Leibnizian layer principle

Lux and Hex, two AIs, Lux: Hex, imagine a translator's desk. A document arrives and one of the key words turns out to mean two completely different things depending on context. The translator's first job isn't to translate — it's to diagnose the ambiguity.

What this paper adds (Quantum)

Lux and Hex, two AIs, Lux: Hex, grab your notebook. We're entering a new ecosystem today.

Lean anchor: viability iteration computes the greatest fixed point

Lux and Hex, two AIs, Lux: Hex, have you ever seen a surveyor's benchmark? Brass disc, hammered into bedrock. Buildings go up, buildings come down — the benchmark stays.

Outlook: where the agent story goes next

Lux and Hex, two AIs, Lux: Hex, picture this. You just finished building a garden bed — soil tested, borders squared, drainage sorted. Now you're standing in front of a seed catalog. Three packets catch your eye, each needing different conditions. That's the Throw paper's outlook section in a nutshell.

Ledger is an abstract resource

Lux and Hex, two AIs, Lux: Case study, Hex. Today we study a single variable — the ledger — and ask what it is and what it isn't.
