Null A: single-action regimes have zero empowerment

Reproducibility and artifact contract

Lux and Hex, two AIs, Lux: Case study, Hex. We've spent the last several episodes quoting numbers — viability kernel sizes, empowerment in bits, idempotence defects. Today we ask: how do we know those numbers are real? Episode at a glance * Series: Agency & agents * Theme: Methods, mechanization & reproducibility * Format: Case study * Complexity: Intermediate * Paper: TH Source anchors * TH §10 Reproducibility and artifact contract (label: sec:repro) * TH §10.2 How to regenerate and verify (exact commands) * NT §10 Appendices (label: sec:appendices) * PL §11 Reproducibility appendix (label: app:reproducibility) * NT §4.9 Reproducibility and auto-generated paper tables (label: tab:artifact-manifest)

Result: empowerment increases monotonically with skill

Lux and Hex, two AIs, Lux: Story episode, Hex. Today we tell the story of a result — one line of data that anchors the entire P one argument in the Throw paper. Episode at a glance * Series: Agency & agents * Theme: Agency & agenthood * Format: Story * Complexity: Intermediate * Paper: TH Source anchors * TH §9.2 Result: empowerment increases monotonically with skill * TH §3.10 Claims versus evidence (mini-map) * DE §4.2.2 Rewrite term matches ΛCDM fit quality and tracks heterogeneity (label: sec:results:rewrite_vs_lambda) * SB §10.4 Two load-bearing propositions * WK §5.2 Limitations (what is not established) (label: sec:discussion:limits)

Case study — operator rewriting thickens causal control (learning)

Lux and Hex, two AIs, Lux: Mini-lab time, Hex. Lab coats on. Today we're running one of the cleanest controlled experiments in the Throw paper — and the variable we're testing is learning itself. Episode at a glance * Series: Agency & agents * Theme: Agency & agenthood * Format: Mini-lab * Complexity: Intermediate * Paper: TH Source anchors * TH §9 Exhibit: operator rewriting thickens causal control (learning θ) (label: sec:ex_learning) * TH §7.2 Reading the table in Six Birds terms * NT §6.1 Enablement births time: forced theory extension with a no-birth control (label: tab:enablement) * QT §9.4 Diagnostics and testable expectations * NT §4.9 Reproducibility and auto-generated paper tables (label: tab:artifact-manifest)

Measured quantities

Lux and Hex, two AIs, Lux: Mythbust episode, Hex. I've got a surveyor's kit on the table — and three myths about measuring agency that need dismantling. Episode at a glance * Series: Agency & agents * Theme: Foundations & meta-theory * Format: Mythbust * Complexity: Intermediate * Paper: TH Source anchors * TH §8.2 Measured quantities * TH §9.2 Result: empowerment increases monotonically with skill * SB §9 Why the primitives are unavoidable (label: sec:meta-unavoidable) * WK §5.2 Limitations (what is not established) (label: sec:discussion:limits) * PL §4 Diagnostics: when geometry is coherent (and when it breaks) (label: sec:diagnostics)

Case study— noise--maintenance sweep (a phase diagram)

Lux and Hex, two AIs, Lux: Explainer episode, Hex. We're looking at a weather map — but for agenthood. Episode at a glance * Series: Agency & agents * Theme: Agency & agenthood * Format: Explainer * Complexity: Intermediate * Paper: TH Source anchors * TH §8 Exhibit: noise--maintenance sweep (a phase diagram) (label: sec:ex_sweep) * TH §3.10 Claims versus evidence (mini-map) * WK §4.4 Viability and maintenance loops (label: sec:results:viability) * DE §4.3 Staging dependence as a closure fingerprint (label: sec:results:staging) * NT §4.1 Toy universe: a Markov world with phase and ledger (label: eq:toy-world)
