  "summary": "Iteration 19 — Vyapar parity for New Sale Invoice. Backend: 27/27 pytest PASS (21 smoke regression + 6 new Vyapar parity tests). Frontend: 100% — all 14 data-testid hooks present and wired correctly. Verified inline InvoicePrefixPicker, OldBillSearch (12 INV results), tax-mode toggle (Tax column hides on Without GST), PartyPicker with '+ Add Party' pinned ABOVE Walk-in (y=320 vs y=385), QuickAddPartyModal contains all Vyapar fields (Email, GSTIN, Billing Address, Shipping Address + 'Same as billing' checkbox, Opening Balance + To Receive/To Pay toggle, Credit Limit). End-to-end party→invoice flow PASSED — POST /api/parties 200 with full payload (email, shipping_address, opening_balance=5000, opening_balance_type='debit', credit_limit=25000), party auto-selected, POST /api/invoices 200 created invoice INV/26/00013, redirected to /sales/<inv_id>. Explicit prefix_id payload correctly honored by resolve_next_invoice_no_by_id. q-search on invoice_no AND party_name both work via $regex.",

    "critical": [],
    "minor": [
      {"endpoint": "POST /api/invoices", "issue": "Backend stores party_name from payload only — does NOT auto-fill from party_id lookup. If a buggy client POSTs without party_name, the q-search by party-name will silently miss that invoice. Current frontend always sends both fields so no user-visible impact, but defensive auto-fill in routes.py create_invoice (~line 800) would be safer."}
