Racha

O jeito mais rápido de fechar a conta. QR na mesa → vê a conta → racha com os amigos → paga com Pix → mesa livre. Pay-at-table para restaurantes brasileiros.

Sister product to Seatable (separate repo, brand, and infra; same company and sales machine). Strategy & research: restaurant-ai-mcp/.claude/plans/2026-07-17-racha-pay-at-table-brazil/README.md. Operating rules: CLAUDE.md — the non-negotiables are law here.

Status: v0 foundation

• Money core: split engine (api/_lib/checks/split-engine.js) — integer centavos, exact largest-remainder splits (equal / by item / custom), serviço math
• Check state machine (api/_lib/checks/check-state.js) — event-sourced, webhook- idempotent, overpay/late-payment never silently lost
• Core schema (supabase/migrations/0001_core.sql) — venues, tables, checks, event log, payments; RLS service-role-only; append via RPC
• Agent OS (.claude/agents/) — payments-architect, fintech-compliance (mandatory gate on money code), market-scout, builder
• PSP adapter (blocked on RFP: Pagar.me Customizado vs Zoop vs Iugu)
• POS adapters: manual (v0) + NCR Colibri (partner application pending)
• Diner PWA + restaurant panel (apps/)
• Supabase project + Vercel project + domain (after name/INPI check)

Development

npm install
npm test        # split engine + state machine suites — must be green, always

The gate

Pilot venues must reach ≥25% of checks migrating to Racha by week 8 or the product parks. Everything in the roadmap is subordinate to that number.
