Served FLDOE-derived share vs NCES CCD race subtotal. (a) CONSISTENCY, not accuracy: |Δ| within the process bound min(9 × hidden cells, unallocated) / total + 0.5 pp for ≥ 99% of school-years, per share, with hidden cells counted as the loader counts them — any allocation that respects the cap and sums to the total satisfies it (the plain equal split included), so a failure means a loader defect, not a poor prior; (b) no school-year served with all seven shares equal; (c) ACCURACY against the no-information reference: the served share's mean |Δ| from CCD is no larger than the equal split's (the two coincide except where the capped adjacent-year prior applies, 2022-23). The prior was chosen among five candidates on CCD 2022-23, the same reference reported here (in-sample selection; the held-out split-half check is in docs/cities/miami/probe/race_imputation_prior.py). Mean |Δ| and the within-2-pp share are informational.
