okf asked outright whether the v1.0 gate requires 'the tagged artifact resolves
0.3.1' or 'the fixture set passes against 0.3.1'. It is the second, and the
answer is locked here so a later session cannot quietly upgrade the ask into a
release request against their operator.
They refused to widen their published range to run the measurement, and the
refusal is better than the ask it answers: widening a published range in order
to generate the evidence that would justify widening it is circular, and a red
result would then have meant unwinding a release to fix a test setup. The
measurement has to be able to say no. Their scratch-venv method -- outside the
project environment, --no-deps, guard installed from the v0.3.1 tag, resolved
version asserted from importlib.metadata -- satisfies the gate exactly.
