- cloud/audit_sampling.py (pure, stdlib): mandatory sampling (1.0)
for rebuild cases and for third-failure near-complete cases whose
continuation round still failed; random sampling for the rest
(normal 0.10, critical-path 0.50, ceil so small groups are never
rounded to zero, seed required and recorded for reproducibility).
- Wrong-verdict handling: correct the original conclusion and
retrigger the corresponding flow (wrong pushback ->
cancel_pushback_and_rerun_audit; wrong rebuild ->
halt_rebuild_and_restore; wrong pass -> reopen_audit_and_pushback;
unknown original -> escalate_to_human); every result, correct or
corrected, is appended to the audit-of-audit record.
- Golden-set approval checklist: list reviewed, criteria defined,
sample exclusion, approver+timestamp -- all human-confirmed before
approval; sample entries (sample=True or sample- ids) are dropped
and counted, never counted as golden.
- metrics.build_report gains an optional sampling_plan section;
without a plan it states sampling is pending, never implying the
audit was re-examined.
