v2.1.0 - Ascention Release

What's Changed in v2.1.0 (Ascention)

Major Enhancements

• Ascention Pipeline Parity (pontifex.core.features):
  • Synchronized feature extractor to produce full 49-dimensional vectors including wide-baseline colors (u-r, g-i, r-z, i-y, z-H).
  • Exact numerical and architectural parity with pre-trained Ascention challenge models.
• Stratified 5-Fold Out-Of-Fold (OOF) Calibration (pontifex.nz.runner):
  • Zero-leakage out-of-fold calibration measuring genuine adjacent-bin spillover.
• Documentation & ReadTheDocs:
  • Complete overhaul of tomography and n(z) docs detailing DIR SOM transfer reweighting, boundary entropy regularization, and correlated GP spatial sampling.
• DESC SRD Stage IV Compliance:
  • Confirmed 100% compliant across all benchmark tasksets (|delta mu| <= 0.00325, |delta sigma| <= 0.00880, kappa = 0.858).
• Test Suite:
  • All 21 unit and integration tests passing.
