v3.18.3 against its own round-17 review, the live filesystem (verified
all 17 Appendix B paths exist), and the SQLite database. Verdict: Minor
Revision; the round-18 finding was that the v3.18.3 reconciliation note
for 55,921 vs 55,922 was empirically false (DB query showed the cause
was accountants.firm vs signatures.excel_firm field mismatch, not
floating-point/snapshot drift).
