# FREEZE — Experiment 18: Label Granularity Robustness

Frozen before any granularity-varied metric value was computed. No scIB metric
has been evaluated under any labelling other than the leaf annotation already
published in Paper D's exp10 audit.

## Attestation

The pure helpers (granularity ladder, inversion rate, bootstrap) were verified
on synthetic data before this timestamp. No Census query was issued and no
scib-metrics call was made with a coarsened label vector prior to freezing.
