Captures user-confirmed CRA registration & filing setup:
- Annual GST/HST filer (return Mar 31, instalments if prior net tax ≥ \$3k)
- Annual T2 filer (return Jun 30, balance due Mar 31 for CCPC)
- HST# 741224877 currently stored as 9-digit BN root only; normalize to
full 15-char '741224877 RT0001' for tax-report validation
- Quick Method opportunity downgraded — \$400k threshold applies to
associated-group totals; Nexa+Westin+Divine combined likely exceeds it
- Add HST cadence escalation flag (quarterly auto-trigger at \$1.5M)
- Acceptance criteria expanded with HST# format, filer config, and
intercompany invoice test case
