vary across pyarrow versions). The committed bytes + `SHA256SUMS` are canonical regardless.

are canonical regardless. **A change to this fixture is a change to the contract (§10)** —
do not regenerate casually.

**`pyarrow` is the version-sensitive one; `views_frames` is not.** Parquet bytes vary
across pyarrow versions — that is why the pin is `>=16.1.0,<17.0.0` and why a local
pyarrow 23.x fails byte-parity while CI passes (register **C-72**). `views_frames` sits
above it: the fixture was generated under `1.0.0`, CI has reproduced it continuously under
`1.6.0`, and `1.10.2` was verified to regenerate **all five artifacts byte-identically**
before the pin was raised (2026-08-02). Raising it again does not require regenerating the
fixture — but it does require proving that, the same way.
