Record the approved implementation plan and incorporate the existing 12.1.0 version and changelog preparation. Plan: /Users/jlogan/git/cfsem-py/hyp2f1_plan.md Co-Authored-By: Codex <noreply@openai.com>
… data Add the Complex64 Rust API boundary, dense slice scaffolding, and pinned mpmath reference fixtures for the numerical implementation. Plan: hyp2f1_plan.md Co-Authored-By: Codex <noreply@openai.com>
Implement and independently validate the private branch-aware elementary, Lanczos gamma, digamma, reciprocal-gamma, and epsilon-difference helpers. Retain the MIT attribution for adapted stabilization recurrences. Plan: hyp2f1_plan.md Co-Authored-By: Codex <noreply@openai.com>
…uation Add exceptional-case precedence, terminating-polynomial evaluation, Gauss unity values, compensated direct summation, cancellation diagnostics, and finite-cap failure behavior. Plan: hyp2f1_plan.md Co-Authored-By: Codex <noreply@openai.com>
Add Euler and Pfaff normalization, stable one- and infinity-centered recurrences, deterministic six-region selection, near-integer sweeps, and signed-zero branch-cut handling. Plan: hyp2f1_plan.md Co-Authored-By: Codex <noreply@openai.com>
Add forced radial anchors, differential-equation Taylor recurrence, bounded convergence handling, and upper/lower inside/outside annular-gap fixtures. Plan: hyp2f1_plan.md Co-Authored-By: Codex <noreply@openai.com>
Cover serial and Rayon-parallel kernels across empty, singleton, sub-slice, mixed-region, NaN, and transactional mismatch cases with bitwise scalar equivalence. Plan: hyp2f1_plan.md Co-Authored-By: Codex <noreply@openai.com>
…binding Add the complex128-only contiguous array binding with serial/parallel dispatch, package exports and typing, plus extraction and structural error tests. Plan: hyp2f1_plan.md Co-Authored-By: Codex <noreply@openai.com>
Add shared mpmath and SciPy-subset Python validation, mathematical regressions, Criterion coverage across regions and vector sizes, and the finalized public contract documentation. Plan: hyp2f1_plan.md Co-Authored-By: Codex <noreply@openai.com>
Add high-precision acceptance fixtures for the exact logarithmic m=0 connection limits at z=1 and infinity. Plan: hyp2f1_plan.md Co-Authored-By: Codex <noreply@openai.com>
Mark the approved implementation plan complete after full verification and converged integration review. Plan: hyp2f1_plan.md Co-Authored-By: Codex <noreply@openai.com>
