key(run) is the sha256 the cloud derives as a run's key: benchmark,
split, system, version, k, temperature, max_tokens, embedder, reader and
the four digests, each as text and NUL-terminated. tests/test_measure.py
holds the vectors hanzo-inc/cloud's apps/research TestKeyVector does.
Run keeps the crate's fields; the key is computed, not carried.
Research.measure(identity, fn, force=False) asks for a complete run under
that key and returns the latest to end without calling fn. A miss, a
partial run or force calls fn, records the run and returns it as read
back. fn may not change an identity field.
Arena.post_run follows the arena: it answers the latest run held per
benchmark, or that nothing was queued, and spends nothing, so confirm,
endpoint and attempts go. Admission becomes Measurements.
