# PRET standards audit

Generated by `python3 tools/audit_pret_standards.py` from the mechanical
rules in `docs/PRET_STANDARDS.md`. Semantic names, const correctness,
structure accuracy, and whether a match is a fragile optimizer accident
still require human review.

Manifest ranges reviewed: **1771**
Errors: **125**
Warnings: **0**
Documented low-level exceptions: **0**
