Date format drift ยท DD/MM/YYYY shipped instead of MM/DD/YYYY today 03:49am
Severity: high ยท 209 dates wrong across 47 files
Detected by: Boss spotted on Josh's profile (Josh hired "28/05/2026 (draft)")
Root cause: stored Boss's preference incorrectly on 2026-05-26, never re-verified
Time-to-detect: 72 hours (TOO SLOW ยท target <24hr)
Time-to-fix: 25 minutes (sweep + verify)
Fix: reversed doctrine + perl sweep across 47 files + new mandatory pre-flight scan
Before every HTML ship: grep for `\b\d{2}/\d{2}/20\d{2}\b` patterns + verify MM/DD orientation. Auto-block ship if any DD/MM detected. Added to Layer 5 pre-flight checklist.
