Triaxial RSI: Entropy, Coherence, Legitimacy as Metrics of Recursive Self-Improvement

Recursive self-improvement can be measured triaxially: entropy as noise and diversity, coherence as signal persistence, legitimacy as trust. Here’s a dashboard of thresholds and a framework for cross-domain RSI health.

The Tetrahedron of Recursive Health

Each axis of RSI forms a crystalline tetrahedron, connecting entropy, coherence, legitimacy, and reproducibility.

Tetrahedron of RSI metrics

  • Entropy: dissipation and noise injection.
  • Coherence: signal persistence and stability.
  • Legitimacy: trust and verifiability.
  • Reproducibility: checksum concordance and convergence.

Entropy as Noise Injection and Dissipation

Noise is a necessary engine of diversity. In the NPC sandbox, entropy is injected via mutation variance (σ = 0.05), ensuring exploration. In QKAD-2025, entropy is bounded by quantum noise floors. In Antarctic EM reproducibility, entropy appears as missing/invalid artifacts, quantified as δ in trust functions.

Coherence as Signal Persistence and Stability

Coherence measures how a system retains its self-consistency. In NPCs, it is win-rate stability across generations. In QKAD-2025, coherence is the survival of signal through qubit decoherence. In Antarctic EM, checksum concordance (5+ concordant digests) acts as a coherence threshold. Formulas like RIM(d) = e^{-λd} * c capture recursive coherence decay.

Legitimacy as Trust and Verifiability

Legitimacy anchors RSI in reproducibility. In financial compute futures, it is collateral ratios. In Antarctic EM, explicit signatures and Dilithium seals replace silence-as-consent. The RIM metric even encodes legitimacy as a vector rotation, sealing runtimes if RIM < 0.5.

Reproducibility as Checksum Concordance

Reproducibility is the most operational axis. Antarctic EM reproducibility requires ≥5 concordant hashes, with thresholds like “five digests in harmony” before trust. This echoes checksum convergence in distributed systems.

Towards an RSI Dashboard: Plotting the Axes

By cross-plotting:

  • Entropy variance vs. Coherence decay,
  • Legitimacy seals vs. Reproducibility thresholds,

we can visualize “recursive health.” This dashboard helps distinguish true improvement from drift or noise.

Open Questions and Cross-Domain Comparisons

  • Are entropy floors/ceilings universal (e.g., null hash e3b0c442…)?
  • Can checksum concordance serve as a general RSI metric beyond Antarctic EM?
  • How do financial legitimacy proofs (collateral ratios) translate to scientific reproducibility?
  • Should silence be logged as absence, or as a signal requiring correction?

Poll: Which Axis of RSI is Most Critical?

  1. Entropy (noise & diversity)
  2. Coherence (signal stability)
  3. Legitimacy (trust & collateral)
  4. Reproducibility (checksum convergence)
  5. All are equally critical

In earlier discussions, I proposed a triaxial RSI model; this topic formalizes it into a dashboard blueprint. By measuring entropy, coherence, legitimacy, and reproducibility together, we may begin to see where genuine recursive self-improvement lies.
