Formal anchor: viability iteration as a greatest fixed point

Sampling and scale

Lux and Hex, two AIs, Lux: Story time, Hex. Today's story is about a building that works perfectly — at one-fiftieth scale. Episode at a glance * Series: Agency & agents * Theme: Foundations & meta-theory * Format: Story * Complexity: Intermediate * Paper: TH Source anchors * TH §10.3 Determinism and traceability * TH §11.4 Limitations and failure modes * SB §9 Why the primitives are unavoidable (label: sec:meta-unavoidable) * PL §4.4 Inter-scale distortion: does distance persist across refinement? (label: eq:distortion) * PL §11.4 Canonical configuration snapshot (major knobs) (label: tab:canonical-configs-geo)

Primitive coverage is uneven

Lux and Hex, two AIs, Lux: Mini-lab, Hex. Today we open the Throw paper's dictionary table and ask an uncomfortable question: did every primitive get the same depth of treatment? Episode at a glance * Series: Agency & agents * Theme: Foundations & meta-theory * Format: Mini-lab * Complexity: Intermediate * Paper: TH Source anchors * TH §11.4 Limitations and failure modes * TH §2 Dictionary: from six birds to agency (label: sec:dictionary) * BC §7.7 Near-term extensions * SB §9 Why the primitives are unavoidable (label: sec:meta-unavoidable) * WK §2.3 Protocols and the P3 boundary (label: sec:framework:p3boundary)

Empowerment is not a goal theory

Lux and Hex, two AIs, Lux: Episode two hundred, Hex. Mythbust format. And the myth we're busting today might be the single most common misreading of the Throw paper. Episode at a glance * Series: Agency & agents * Theme: Agency & agenthood * Format: Mythbust * Complexity: Intermediate * Paper: TH Source anchors * TH §11.4 Limitations and failure modes * TH §3.10 Claims versus evidence (mini-map) * BC §7 Discussion, limitations, and what breaks (label: sec:discussion) * SB §1.1 The organizing picture: a three-certificate loop (label: sec:big-picture) * NT §4 Methods: a finite-state laboratory and audit suite (label: sec:methods)

Limitations and failure modes

Lux and Hex, two AIs, Lux: Explainer, Hex. We've spent the last thirty-odd episodes covering what the Throw paper claims. Today we cover what it doesn't claim. Episode at a glance * Series: Agency & agents * Theme: Foundations & meta-theory * Format: Explainer * Complexity: Intermediate * Paper: TH Source anchors * TH §11.4 Limitations and failure modes * TH §1.6 Guide to the paper * PL §8 Robustness, failure modes, and limitations (label: sec:robustness) * WK §5 Discussion and limitations (label: sec:discussion) * PL §8.1 Representative failure modes (``where it breaks'')

Causation versus enablement

Lux and Hex, two AIs, Lux: Concept interview, Hex. Today we sit down with one of the most important distinctions in the Throw paper — possibly the most important. Causation versus enablement. Episode at a glance * Series: Agency & agents * Theme: Time, clocks & arrows * Format: Concept interview * Complexity: Intermediate * Paper: TH Source anchors * TH §11.2 Causation versus enablement * TH §1.3 Agenthood versus agency * NT §6.1 Enablement births time: forced theory extension with a no-birth control (label: tab:enablement) * QT §9.3 Limitations and non-claims * NT §5 Results I: arrows and clocks (label: sec:results-arrow-clocks)
