+## ✨ Funcionalidades
+
+### Core
+- 🔐 **Autenticação JWT** via Supabase — login com email/senha, modo demo sem credenciais
+- ✏️ **Editor Monaco** com syntax highlighting para 27 palavras reservadas SIMPLES (ciano, laranja, verde)
+- 📊 **Layout 3-painéis** com splitters arrastáveis — editor SIMPLES (esq.), NASM viewer (dir.), terminal (inf.)
+- ⚡ **Compilação REST** (`POST /api/compile`) — código SIMPLES → NASM x86 32-bit com timeouts
+- 🔴 **Erros no editor** — marcadores Monaco na linha/coluna exata do erro de compilação
+
+### Execução Interativa
+- 🔄 **WebSocket `/ws/run`** — protocolo completo com máquina de estados (IDLE → COMPILING → EXECUTING)
+- 🖥️ **Terminal real** via xterm.js — suporte a `leia` (stdin) e `escreva` (stdout) interativo
+- ⏹️ **Botão Stop** — interrompe execução com SIGTERM → SIGKILL em cascata
+- ⏱️ **Timeouts** — compilação 15s, execução wall-clock 10s, hard limit Docker 12s
+
+### Segurança (Defense in Depth)
+- 🐳 **9 camadas de isolamento** por sandbox — `--network=none`, `--read-only`, `--cap-drop=ALL`, `--pids-limit=64`, `--memory=128m`, `--cpus=0.5`, non-root, seccomp
+- 🗑️ **Containers descartáveis** — `docker run --rm` após cada execução
+- 🚦 **Rate limiting** — 30 execuções/min por usuário, 120/min por IP
+- 📏 **Validação de input** — código ≤ 64 KB, stdin ≤ 4 KB por mensagem, apenas UTF-8 válido
+
+### Observabilidade
+- 📊 **Métricas Prometheus** em `/metrics` (contadores, histogramas)
+- 📝 **Logs JSON estruturados** via structlog
+- 🏥 **Health check** detalhado por componente (`/api/health`)
+
+### Pipeline de Compilação
+- 🔧 **simplesc (C99)** → NASM `.asm` → `nasm -f elf32` → `.o` → `ld -m elf_i386` → ELF i386
+- 🎭 **Mock fallback** — gera NASM didático quando `simplesc` não está disponível
+- 🖥️ **qemu-user-static** — emula binários x86 32-bit em hosts ARM64 (Oracle Cloud)

-> **Status atual dos mockups:** Os diagramas ASCII acima representam o layout definido no [PRD](./prd-simples-online.md) (seção 9 — Wireframes) e nos [SPRINTS](./SPRINTS.md) (Sprints 1-4).

+## 🧪 Como Testar
+
+### Testes de Backend (Python)
+
+```bash
+cd backend
+
+# Todos os testes
+python -m pytest tests/ -v --tb=short
+
+# Com cobertura
+python -m pytest tests/ -v --cov=app --cov-report=term-missing
+
+# Apenas um módulo específico
+python -m pytest tests/test_compiler.py -v

+python -m pytest tests/test_validation.py -v
+python -m pytest tests/test_errors.py -v
+python -m pytest tests/test_config.py -v
+```
+
+### Testes de Frontend (Vitest)
+
+```bash
+cd frontend
+
+# Testes unitários
+npx vitest run
+
+# Em modo watch
+npx vitest
+```
+
+### Testes E2E (Playwright)
+
+```bash
+cd frontend
+
+# Instalar navegadores (primeira vez)
+npx playwright install chromium
+
+# Rodar testes E2E
+npx playwright test
+```
+
+### Teste Manual Rápido
+
+```bash
+# 1. Subir tudo
+docker compose up --build -d
+
+# 2. Verificar health
+curl http://localhost/api/health
+# → {"status":"healthy","version":"1.0.0","components":{...}}
+
+# 3. Compilar código SIMPLES
+curl -X POST http://localhost/api/compile \
+  -H "Content-Type: application/json" \
+  -d '{"code":"programa teste\ninicio\n  escreva \"ola mundo\"\nfim"}'
+# → {"success":true,"asm":"section .data\n  str1 db \"ola mundo\",10\n..."}
+
+# 4. Testar rate limit (30 requisições rápidas)
+for i in $(seq 1 35); do
+  curl -s -o /dev/null -w "%{http_code}\n" http://localhost/api/health
+done
+# As últimas devem retornar 429 (Too Many Requests)
+
+# 5. Acessar a IDE
+# Abra http://localhost no navegador
+# No modo demo (VITE_DEMO_MODE=true), clique em "Entrar sem login"
+# Digite um programa SIMPLES e clique ▶ Compilar
+```
+
+### Teste de Segurança do Sandbox
+
+```bash
+# Verificar se os containers são criados com isolamento correto
+docker inspect $(docker ps -q --filter "ancestor=simples-runner:latest") \
+  --format '{{.HostConfig.NetworkMode}} {{.HostConfig.ReadonlyRootfs}}'
+
+# Deve retornar: "none true"
+```
