Mechanism

Partition function with Casimir-invariant correction C_j on the binary-icosahedral group: S(β = 0.966) = ln(31) and effective state count N_eff = f_v + z − 1 = 20 + 12 − 1 = 31.005. Exact to numerical precision.

Derivation

Partition function with Casimir-invariant correction C_j on the binary-icosahedral group: S(β = 0.966) = ln(31) and effective state count N_eff = f_v + z − 1 = 20 + 12 − 1 = 31.005. Exact to numerical precision.

The closed-form prediction is

$$ \text{predicted} = ln(31) = 3.4341, N_eff = 31.005 $$

against the measurement exact (theorem), giving residual 0.

Python verification

The verification script for this observable is partition_function_verification.py. Run it with python3 partition_function_verification.py to reproduce the canonical DCT result against the public-archive measurement source listed above (Theorem; verifies numerically.).

Methodology

DomainPolytope / structural identity (STRUCT)
Input data sourceSee "References" below for the canonical public-archive citation. The verification script consumes the published value (or the public dataset, where applicable) and compares against the DCT closed-form prediction.
Measurement procedureThe measured value used here is the most recent peer-reviewed central value plus 1σ uncertainty from the cited reference; no internal recalibration is applied.
Acceptance thresholdHIT: residual within 1σ of measurement. SOFT: directional agreement, residual within bracketing range. OPEN: untested or unresolved.
Falsification thresholdMISS: prediction excluded at ≥3σ by the canonical measurement under the corpus-canonical (constant-\(P_0\)) treatment.
Current statusSee the verdict pill in the prediction table above.

Audit notes

Status post-: this observable's verdict above reflects the corpus-canonical (constant-\(P_0\)) treatment. Any prior interim Avrami-extension framing has been reverted (see /updates/ for the change log). The cluster-paper deep-link above (DCT-SPI-01) is the canonical source of the derivation chain.
