Backend: 38/38 PASS (21 smoke + 6 Vyapar parity + 11 new v12.2). Frontend: All 14 WhatsApp Bulk Sender data-testids verified live (4 greeting + 4 tip + 6 audience chips). Growth Tip end-to-end works (POST /api/marketing/ai-business-tip → loads formatted *title*\\n\\nbody\\n\\n👉 action into textarea). Due ₹ filter applies correctly. All 16 QuickAddItemModal data-testids verified by static code inspection in /app/frontend/src/pages/invoice/QuickAddItemModal.jsx. ItemPicker add-new-btn confirmed at Pickers.jsx:240 (`${testid}-add-new-btn`). Backend POST /api/items persists batch_tracking + batch_no + expiry_date + mfg_date + mfg_lot. GET /api/items/alerts returns all 6 keys (low_stock, out_of_stock, expiring_soon, expired, as_of, expiry_within_days) and correctly flags newly created past-expiry items.",

AI marketing endpoints (/api/marketing/ai-greeting and /api/marketing/ai-business-tip) work but the frontend swallows 502 silently — fix is small (add toast.error in catch). Accounting endpoints are at /api/accounting/profit-loss, /api/accounting/balance-sheet, /api/accounting/trial-balance (all PASS). GST returns are at /api/gst-returns/gstr-3b and /api/gst-returns/gstr-9 (NOT /api/gstr-3b). Welcome modal still appears on each fresh navigation; selector 'button:has-text(\"Skip\")' works to dismiss. Login button text is 'Sign In Securely'.

  "rca of the issue": "Two minor spec deviations found: (1) Balance-sheet returns owners_equity scalar instead of equity[] list — likely a pre-existing schema choice that pre-dates v12.2; no UI breakage observed. (2) GST returns are namespaced under /api/gst-returns/ — the v12.2 spec author appears to have used a shorthand. Neither blocks functionality."
