Closes#145.
pyarrow==20.0.0was a direct, exact-pinned dependency with zero imports anywhere in cldk/, tests/, or docs — the orphaned companion of the already-removed pandas dependency (#145's original ask). Because pyarrow 20.0.0 ships wheels for cp39–cp313 only, everypip install cldkon Python 3.14 fell back to the sdist and attempted an Arrow C++ source build, failing on machines without a C++ toolchain.Removal, not a version bump: nothing uses it, so bumping to a cp314-wheeled pyarrow would keep shipping ~40 MB of unused Arrow; pinning the SDK to ≤3.12 would punish all users for a dead dependency.
Gates:
uv lockresolves clean (157 packages, pyarrow gone);import cldksmoke passes; python/models/typescript suites — 67 passed, 25 skipped, 23 pre-existing fixture errors (gitignored TS golden fixture, tracked in #255). Scope note: this removes the known 3.14 install blocker; full 3.14 support verification across remaining deps (ray, tree-sitter, libclang) is separate.
