Backend half of offline Phase 1. Lets the offline outbox replay a write after a
lost response without executing it twice (e.g. an order whose POST reached the
server but whose reply never came back).
- IdempotencyRecord entity + table (unique index on (Scope, Key)); migration
AddIdempotencyRecords. Standalone POCO — no tenant/soft-delete filters.
- IdempotencyMiddleware (after TenantMiddleware, before plan-limit/controllers):
opt-in via `Idempotency-Key` header on POST/PUT/PATCH/DELETE.
* Completed key → replays stored status+body with `Idempotent-Replay: true`.
* In-progress key → 409 IDEMPOTENCY_IN_PROGRESS; the unique index serializes
racing first requests; stale (>60s) reservations are recovered after a crash.
* Only <500 responses are cached; 5xx is released so the client can retry.
Bookkeeping runs in isolated DI scopes so it never contaminates the controller's
unit of work. Keys are scoped per café — no cross-tenant collisions.
- 5 middleware tests (replay/execute-once, distinct key, pass-through, tenant
isolation, 5xx-not-cached). Full suite 86 passing.
Next in Phase 1: generalize the POS order queue into a generic client outbox that
sends these keys and remaps client→server ids.

Meezi — Day 1 Quick Start
Step 1 — Copy these 4 files to your project root
.cursorrules ← AI rules for Cursor MEEZI_CURSOR_GUIDE.md ← Full development guide docker-compose.yml ← Local DB + Redis README.md ← This file
Step 2 — Start local services
docker-compose up -d
Step 3 — Create project structure
mkdir meezi && cd meezi git init
mkdir src web mobile cd src dotnet new sln -n Meezi dotnet new webapi -n Meezi.API --use-controllers dotnet new classlib -n Meezi.Core dotnet new classlib -n Meezi.Infrastructure dotnet new classlib -n Meezi.Shared dotnet sln add Meezi.API Meezi.Core Meezi.Infrastructure Meezi.Shared
cd ../web npx create-next-app@latest dashboard --typescript --tailwind --app
cd ../mobile flutter create meezi_app --org ir.meezi
Step 4 — Open in Cursor
cursor . (from the meezi/ root folder)
Step 5 — Paste this FIRST prompt in Cursor chat (Cmd+L)
Read .cursorrules and MEEZI_CURSOR_GUIDE.md completely. Then do Sprint 1 Week 1:
- Set up the .NET solution with proper references between projects
- Add all NuGet packages listed in the guide to each project
- Create the complete EF Core entity schema from the guide
- Set up AppDbContext with all DbSets
- Create TenantMiddleware and ITenantContext
- Set up Program.cs with full middleware pipeline
Cursor Chat Tips
Ask one sprint at a time
"Do Sprint 2: build the POS order APIs (menu, tables, orders)"
Reference specific sections
"Build the CRM endpoint from Step 10 of MEEZI_CURSOR_GUIDE.md"
Debug with context
"The order API returns 403. Check if TenantMiddleware is injecting CafeId correctly"
Generate Flutter screens
"Build the Flutter POS screen from Sprint 2 in the guide. RTL, Farsi, Riverpod state"
Useful Cursor Keyboard Shortcuts
Cmd+L → Open AI chat Cmd+K → Inline AI edit (select code first) Cmd+I → Composer (multi-file edits) Cmd+. → Quick fix / suggestion Tab → Accept autocomplete
