LFCT CMB TT Production Model — v24 Reference Implementation

## Description This record provides the reference implementation of the Light Frame Cadence Theory (LFCT) CMB TT production model (v24). The code evaluates the angular power spectrum \( D_\ell \) using the carrier-native architecture: \[D_\ell = \left[g_{\mathrm{COS\_POS}}\cdot D_{\mathrm{den}}(\ell) + D_{\mathrm{vel}}(\ell)\cdot\bigl(1 + T_{\mathrm{TR}}(\ell)\bigr)\right]\cdot f^2(\ell/\ell_c)\cdot f_{\mathrm{recov}}(\ell).\] All components are constructed from LFCT structural constants and zero-free-parameter correction amplitudes. --- ### Scope This is a **working research implementation**, not a formal derivation document. It is intended to: - reproduce LFCT CMB TT model outputs across \(\ell \in [2, \sim 2500]\) - provide a concrete, executable realization of the LFIS-29 architecture - enable direct comparison with Planck 2018 TT reference data --- ### Relationship to Dataset This implementation corresponds directly to the dataset: > *LFCT CMB TT Production Model — Wave Test Log (TL.001–TL.027)* The wave-test log documents the full calibration and validation process that led to the correction set used here. --- ### Notes - The code structure reflects iterative development and is intentionally preserved in working form - No free parameters are introduced; all amplitudes are expressed in LFCT structural constants or simple rational forms - Calibration alignment between analytical correction amplitudes and production-model behavior is documented in the associated wave-test dataset --- ### Usage This code may be used to: - reproduce LFCT production-model predictions - evaluate correction sensitivity and residual structure - audit the mapping between LFCT derivation and numerical implementation Users should refer to the associated dataset for full diagnostic context.
