v3.20 — Initial public release

First public release of the CIF Reference Implementation.

Contents

• CIF_Generator_v3_20.ipynb — 145-cell notebook (62 code + 83 markdown)
• COMSOL/ — 3-D Stokes outlet-cell artifacts for Dinh V1/V3 (coarse + extra-coarse mesh, plus .mph source files)
• outputs/ — generated figures and provenance_log.md

Headline result. Under 1-D pressure equilibration with Q_s(0) = 0, the CIF outlet filtrate fraction is F = 2·R_c / (R_s + 2·R_c). Matches the Gifford recursion across five reference devices in three architectural regimes to |ΔF| ≤ 2.35 × 10⁻⁴. COMSOL 3-D Stokes at the Dinh outlets matches paper measurements within 1σ at both V1 (+0.06σ) and V3 (−0.58σ).

Validation. 218 / 218 core validators, 19 / 19 supplementary, 19 regression stamps after full top-to-bottom execution.
