## O Problema
-- Execução de código insegura em ambientes compartilhados.
-- Instalação complexa de toolchain (NASM, ld) para alunos.
-- Falta de ferramentas focadas no aprendizado de compiladores.
+
+
+
+- ⚙️ **Instalação complexa de toolchain** (NASM, ld, binutils i686) para alunos iniciantes
+- 🔓 **Execução insegura** de código arbitrário em laboratórios compartilhados
+- 📉 **Falta de feedback visual** — alunos não veem relação entre código fonte e assembly gerado
+- 🖥️ **Ambiente heterogêneo** — Windows, macOS, Linux com diferentes configurações
+- ⏳ **Tempo perdido** em setup ao invés de aprendizado de compiladores
+
+
---
## Nossa Solução
-- Sandbox seguro baseado em Docker.
-- Isolamento rígido de recursos (cgroups, namespaces).
-- Interface leve e responsiva com Monaco Editor.
-- Comunicação em tempo real via WebSockets.
+
+
+
+### Simples Editor — IDE Web Completa
+
+| Antes | Depois |
+|---|---|
+| Instalar NASM, ld, binutils | **Zero instalação** — abre o navegador |
+| Executar binários localmente (risco) | **Sandbox Docker descartável** com 9 camadas de isolamento |
+| Código fonte + assembly em arquivos separados | **Visualização lado-a-lado** com Monaco Editor |
+| Terminal separado para I/O | **Terminal integrado** via xterm.js + WebSocket |
+| `leia`/`escreva` não testáveis em batch | **Interatividade real** stdin/stdout via PTY |
+
+
---
## Arquitetura
-- **Frontend**: React + Monaco Editor + xterm.js
-- **Backend**: Python (Flask + WebSocket)
-- **Infraestrutura**: Docker (sandbox, `--network=none`, limits)

-## Demonstração
+## Funcionalidades Implementadas
+
+
+
+### ✅ Core (Sprints 1-2)
+- 🔐 **Auth JWT** Supabase — login email/senha + modo demo
+- ✏️ **Monaco Editor** — 27 keywords SIMPLES com syntax highlighting (ciano, laranja, verde)
+- 📊 **Layout 3-painéis** — splitters arrastáveis com double-click collapse
+- 📖 **4 exemplos built-in** — Hello World, Fatorial, Fibonacci, Tabuada
+
+### ✅ Compilação (Sprint 3)
+- ⚡ `POST /api/compile` — REST endpoint com timeout 15s
+- 🔴 **Monaco markers** — erros destacados na linha/coluna exata
+- 📝 **NASM viewer** — painel direito preenchido automaticamente
+- 🎭 **Mock fallback** — NASM didático quando `simplesc` indisponível
+
+### ✅ Execução Interativa (Sprint 4)
+- 🔄 **WebSocket `/ws/run`** — máquina de estados IDLE→COMPILING→EXECUTING
+- 🖥️ **xterm.js** — terminal real com `leia`/`escreva` interativo
+- ⏹️ **Botão Stop** — SIGTERM → SIGKILL em cascata
+- ⏱️ **Timeouts** — wall-clock 10s, hard limit Docker 12s
+
+### ✅ Segurança & Observabilidade (Sprint 5)
+- 🐳 **9 camadas de isolamento** — sem rede, read-only, sem capabilities
+- 🚦 **Rate limiting** — 30/min por user, 120/min por IP
+- 📊 **Prometheus metrics** — `/metrics` com histogramas
+- 📝 **structlog JSON** — todos os logs estruturados
+
+
+
+---
+
+## Demonstração — Fluxo de Uso
-### Fluxo da Demo ao Vivo
+
+
+1. **Acesso** → `http://localhost` → tela de login (ou modo demo)
+
+2. **Editor** → Digitar código SIMPLES com highlighting:
+ ```
+ programa soma
+ inteiro a, b, resultado
+ inicio
+ leia a
+ leia b
+ resultado := a + b
+ escreva resultado
+ fim
+ ```
+
+3. **▶ Compilar** → `POST /api/compile` → NASM aparece no painel direito
+
+4. **▶ Executar** → WebSocket → container Docker sobe → terminal interativo:
+ - Programa pergunta: `Digite o primeiro número:`
+ - Usuário digita: `42`
+ - Programa pergunta: `Digite o segundo número:`
+ - Usuário digita: `17`
+ - Saída: `59`
+ - `[exit code: 0 — 1.42s]`
-1. **Editor**: escrita de código SIMPLES no Monaco Editor com syntax highlighting.
-2. **Compilação**: envio do código ao backend; compilador traduz para assembly NASM.
-3. **Montagem & Linkedição**: NASM + ld produzem executável dentro do container sandbox.
-4. **Execução**: saída exibida em tempo real no terminal xterm.js integrado.
-5. **Segurança**: demonstração das barreiras de isolamento (`--network=none`, limites de CPU/memória, filesystem efêmero).
+5. **■ Parar** → SIGTERM → container destruído em < 2s
-*(Screenshots da interface serão inseridas aqui)*
+6. **Erro** → Código inválido → marcadores vermelhos no editor
+
+
---
-## Próximos Passos
-- Salvar histórico de código.
-- Modo colaborativo (compartilhar snippet via URL).
-- Pool de sandboxes pré-aquecido para latência < 100ms.
-- Modo passo-a-passo (debugger).
+## Segurança — 9 Camadas de Isolamento
+
+
+
+| # | Camada | Mecanismo | Ameaça Mitigada |
+|---|---|---|---|
+| 1 | Container descartável | `docker run --rm` | Persistência de malware |
+| 2 | Isolamento de rede | `--network=none` | Exfiltração de dados |
+| 3 | Filesystem imutável | `--read-only` + `tmpfs:/tmp,size=8m` | Escrita maliciosa |
+| 4 | Limite de memória | `--memory=128m --memory-swap=128m` | Consumo de recursos |
+| 5 | Limite de CPU | `--cpus=0.5` (cgroups v2) | CPU exhaustion |
+| 6 | Limite de processos | `--pids-limit=64` | Fork bomb |
+| 7 | Usuário não-root | `--user=65534:65534` (nobody) | Escalação de privilégio |
+| 8 | Sem capabilities | `--cap-drop=ALL` | Syscalls privilegiadas |
+| 9 | Seccomp | Perfil padrão Docker | Syscalls perigosas |
+
+
+
+### Timeouts em Cascata
+
+```
+Compile timeout (15s) → Wall-clock (10s) → SIGTERM (1s) → SIGKILL → Hard limit Docker (12s)
+```
+
+---
+
+## Resultados
+
+
+
+| Métrica | Valor |
+|---|---|
+| **Issues concluídas** | 45/47 (96%) — #48 e #49 pendentes (Oracle Cloud) |
+| **PRs mergeados** | 30+ |
+| **Testes backend** | 110+ passando (pytest) |
+| **Módulos testados** | 9 (auth, compiler, routes, ws_handler, sandbox, execution, validation, errors, config) |
+| **Sprints concluídos** | 5/6 (Sprint 6 parcial) |
+| **Cobertura do PRD** | ~90% funcionalidades implementadas |
+| **Documentação** | ~3500 linhas (README, PRD, SPRINTS, guias, apresentação) |
+| **Linhas de código** | ~8000 (frontend + backend + testes + infra) |
+
+### Pendências
+
+| Item | Status | Bloqueio |
+|---|---|---|
+| Deploy Oracle Cloud (#48) | ⚠️ IaC pronta | Credenciais OCI |
+| Domínio próprio TLS (#49) | ⚠️ Bloqueado | Depende de #48 |
+| Testes E2E Playwright | 🔄 Parcial | Em andamento |
+| Cobertura ≥ 70% backend | 🔄 ~60% | Mais testes necessários |
+
+
+
+---
+
+## Lições Aprendidas
+
+
+
+### ✅ O que deu certo
+
+1. **PRD como contrato** — 1630 linhas antes do código = alinhamento total
+2. **Docker Compose funcional** — 3 containers em < 30s de startup
+3. **Sandbox com 9 camadas** — auditado: fork bomb, escrita, rede → tudo bloqueado
+4. **Tokenizer Monarch** — 27 keywords coloridas deram credibilidade imediata
+5. **Agentes autônomos (Hermes)** — 45 issues em ~4 dias, aceleração 10x
+
+### ❌ O que faríamos diferente
+
+1. **MVP vertical na semana 2** — login → editor → compilar → ver NASM
+2. **1 PR bootstrap de frontend** — evitar 10 PRs recriando scaffold
+3. **Deploy contínuo desde Sprint 2** — staging, não só local
+4. **Testes desde Sprint 1** — começamos tarde (Sprint 5-6)
+5. **Agentes desde o início** — uso revolucionário na fase final
+
+### 📊 Distribuição
+
+| Integrante | Foco |
+|---|---|
+| **Carlos Barboa** | Arquitetura, PRD, backend, DevOps, segurança, orquestração |
+| **Luan Dias** | Documentação, infraestrutura, testes de cobertura |
+| **Kauan Simão** | Docker, simplesc, frontend, testes E2E |
+

+## 0. Auditoria de Segurança do Sandbox
+
+> **Data da auditoria**: 2026-06-17
+> **Escopo**: Verificação das 9 camadas de isolamento Docker, 3 camadas de timeout,
+> threat model e checklist de segurança conforme PRD §11.2 e §11.6.
+> **Arquivos auditados**:
+> - `backend/app/execution.py` (PtyExecutionStrategy)
+> - `backend/app/sandbox.py` (SandboxFactory)
+> - `backend/app/config.py` (Config / timeout defaults)
+> - `backend/app/limits.py` (Rate limiting)
+> - `backend/app/compiler.py` (CompilerService — compile timeout)
+> - `backend/app/validation.py` (Input validation)
+> - `backend/app/ws_handler.py` (WebSocket handler)
+> - `backend/sandbox_config.py` (TimeoutConfig dataclass)
+
+### 0.1 9 Camadas de Isolamento
+
+Cada camada foi verificada no código-fonte do `PtyExecutionStrategy.execute()`
+(`backend/app/execution.py`, linhas 80–97) e na `SandboxFactory.create_container()`
+(`backend/app/sandbox.py`, linhas 68–85).
+
+| # | Camada | Parâmetro Docker | Valor | Arquivo (linha) | Status |
+|---|--------|-----------------|-------|-----------------|--------|
+| 1 | **Container descartável** | `container.remove(force=True)` | Remoção forçada no `finally` | `execution.py:206-210` | ✅ Equivalente a `--rm` |
+| 2 | **Network isolation** | `network_mode` | `"none"` | `execution.py:84` | ✅ |
+| 3 | **Filesystem read-only** | `read_only` | `True` | `execution.py:89` | ✅ |
+| 3a | **tmpfs limitado** | `tmpfs` | `{"/tmp": "size=8m"}` | `execution.py:90` | ✅ |
+| 4 | **Memory limit** | `mem_limit` | `"128m"` | `execution.py:85` | ✅ |
+| 4a | **Memory swap limit** | `memswap_limit` | `"128m"` | `execution.py:86` | ✅ |
+| 5 | **CPU quota** | `cpu_quota` | `50000` (0.5 CPU) | `execution.py:87` | ✅ |
+| 6 | **PIDs limit** | `pids_limit` | `64` | `execution.py:88` | ✅ |
+| 7 | **Usuário não-root** | `user` | `"65534:65534"` (nobody) | `execution.py:91` | ✅ |
+| 8 | **Capabilities drop** | `cap_drop` | `["ALL"]` | `execution.py:92` | ✅ |
+| 9 | **Seccomp profile** | (Docker default) | Perfil padrão do Docker | Implícito — não desabilitado | ✅ |
+
+**Nota sobre camada 1**: O código não passa `auto_remove=True` (equivalente ao flag
+`--rm` do CLI). Em vez disso, o container é removido explicitamente no bloco `finally`
+com `container.remove(force=True)`. O efeito é o mesmo: containers não persistem após
+a execução, mesmo em caso de erro ou timeout.
+
+**Verificação adicional — SandboxFactory**: O `SandboxFactory.create_default_config()`
+(`sandbox.py:60-62`) e `SandboxFactory.create_container()` (`sandbox.py:64-88`)
+espelham exatamente os mesmos parâmetros de segurança, garantindo consistência
+por toda a aplicação. O `SandboxConfig` dataclass (`sandbox.py:20-43`) define os
+valores padrão (`network_mode="none"`, `mem_limit="128m"`, etc.) com defaults
+idênticos aos usados no `PtyExecutionStrategy`.
+
+### 0.2 3 Camadas de Timeout (Defense in Depth)
+
+Conforme PRD §11.3 e `backend/sandbox_config.py`, as três camadas operam em
+sequência para garantir que nenhuma execução ultrapasse os limites:
+
+| # | Camada | Mecanismo | Valor | Arquivo (linha) | Status |
+|---|--------|----------|-------|-----------------|--------|
+| 1 | **Compile timeout** | `subprocess.run(timeout=)` | **15s** | `compiler.py:136,161,174` | ✅ |
+| 2 | **Wall-clock timeout** | `asyncio.wait_for(timeout=)` | **10s** | `execution.py:163` | ✅ |
+| 3 | **Docker hard stop** | `stop_timeout=` | **12s** | `execution.py:96` | ✅ |
+
+**Detalhamento**:
+
+**Camada 1 — Compile timeout (15s)**:
+- Aplica-se a cada estágio individualmente: `simplesc`, `nasm`, `ld`
+- Todos usam `subprocess.run(..., timeout=config.compile_timeout_s)` com lista de args
+- `compiler.py:132-137` — `_run_simplesc()`: timeout na compilação SIMPLES→NASM
+- `compiler.py:157-163` — `_run_nasm()`: timeout na montagem NASM→ELF32
+- `compiler.py:170-176` — `_run_ld()`: timeout na linkagem ELF32→binário
+- O `TimeoutExpired` é capturado em `compiler.py:97-104` e retornado como
+ `CompileResult(success=False, error_message="Compilation timed out...")`
+
+**Camada 2 — Wall-clock timeout (10s)**:
+- Aplica-se ao tempo total de execução do binário no sandbox
+- Implementado via `asyncio.wait_for()` em `execution.py:162-164`
+- Timeout vem de `config.exec_timeout_s` (default: 10, env: `EXEC_TIMEOUT_S`)
+- Ao expirar: SIGTERM → sleep(1) → SIGKILL (`execution.py:166-172`)
+- O `SIGTERM_GRACE_S = 1` (definido em `sandbox_config.py:24`) é respeitado
+
+**Camada 3 — Docker hard stop (12s)**:
+- Rede de segurança: se as camadas 1 e 2 falharem, o Docker força SIGKILL
+- `stop_timeout=12` em `execution.py:96`
+- `DOCKER_STOP_TIMEOUT_S = 12` em `sandbox_config.py:21`
+- Invariante validada: `exec_timeout_s + sigterm_grace_s < docker_stop_timeout_s`
+ (10 + 1 = 11 < 12 ✅) — `sandbox_config.py:72-84`
+
+**Validação de invariante**: A função `validate_timeouts()` em `sandbox_config.py:72-84`
+garante que o soft timeout (10s) + grace period (1s) é estritamente menor que o
+Docker hard stop (12s). Isso evita que o Docker mate o container com SIGKILL antes
+que a aplicação tente o graceful shutdown com SIGTERM.
+
+### 0.3 Threat Model
+
+Cada ameaça identificada no PRD §11.6 foi verificada contra as mitigações
+implementadas no código.
+
+| # | Ameaça | Mitigação(ões) | Implementação | Status |
+|---|--------|---------------|---------------|--------|
+| 1 | **Loop infinito** | Wall-clock timeout 10s + Docker stop_timeout 12s | `execution.py:162-172` (asyncio.wait_for + SIGTERM/SIGKILL) | ✅ |
+| 2 | **Fork bomb** | `pids_limit=64` | `execution.py:88` | ✅ |
+| 3 | **Memória ilimitada** | `mem_limit=128m` + `memswap_limit=128m` | `execution.py:85-86` | ✅ |
+| 4 | **Exfiltração via rede** | `network_mode="none"` | `execution.py:84` | ✅ |
+| 5 | **Escape do container** | user=65534:65534 + cap_drop=ALL + seccomp default + read_only fs | `execution.py:89,91,92` | ✅ |
+| 6 | **Abuso de execuções** | Rate limit 30/min (user) + 120/min (IP) | `limits.py:33-44` (Flask-Limiter) | ✅ |
+| 7 | **JWT roubado** | Expiração curta (Supabase padrão 1h) + validação `sub`/`exp` | `ws_handler.py:172-173` (verify_jwt + extract_user_id) | ✅ |
+| 8 | **Code injection** | `subprocess.run` com lista de args, nunca `shell=True` | `compiler.py:132-136,157-162,170-175` | ✅ |
+
+**Mitigações adicionais verificadas**:
+
+| Medida | Descrição | Local |
+|--------|----------|-------|
+| Validação de entrada | Código limitado a 64 KB, apenas caracteres imprimíveis + ASCII estendido | `validation.py:19-52` |
+| Validação de stdin | Dados stdin limitados a 4096 bytes | `validation.py:54-68` |
+| Rate limit duplo | Limiter por user_id + limiter separado por IP | `limits.py:33-44` |
+| Container cleanup | `container.remove(force=True)` no finally, mesmo em exceções | `execution.py:206-210` |
+| Workdir cleanup | `shutil.rmtree()` no cleanup da conexão | `compiler.py:180-185` |
+| Auth obrigatória | JWT verificado em todo WebSocket connect | `ws_handler.py:153-174` |
+
+### 0.4 Checklist de Verificação
+
+Itens verificados nesta auditoria (2026-06-17):
+
+- [x] **Isolamento**: Todos os 9 parâmetros de segurança do Docker conferidos no `PtyExecutionStrategy.execute()`
+- [x] **Isolamento**: `SandboxFactory` espelha os mesmos parâmetros (consistência via Factory pattern)
+- [x] **Timeout 1**: `subprocess.run(timeout=15)` em todos os 3 estágios de compilação (simplesc, nasm, ld)
+- [x] **Timeout 2**: `asyncio.wait_for(timeout=10)` no executor com sequência SIGTERM → SIGKILL
+- [x] **Timeout 3**: `stop_timeout=12` no container Docker
+- [x] **Invariante**: `exec_timeout_s + sigterm_grace_s < docker_stop_timeout_s` (11 < 12 ✅)
+- [x] **Network**: `network_mode="none"` — sem interface de rede no container
+- [x] **Filesystem**: `read_only=True` + `tmpfs` limitado a 8 MB
+- [x] **Usuário**: `nobody:nobody` (UID 65534, GID 65534)
+- [x] **Capabilities**: `cap_drop=["ALL"]` — todas as capabilities Linux removidas
+- [x] **Seccomp**: Perfil padrão do Docker ativo (não desabilitado no código)
+- [x] **Rate limit**: Flask-Limiter configurado para 30 req/min (user) + 120 req/min (IP)
+- [x] **Code injection**: Nenhuma ocorrência de `shell=True` — todas as chamadas usam lista de args
+- [x] **Validação**: Código validado (tamanho + charset) antes da compilação
+- [x] **Validação**: Stdin validado (tamanho) antes do envio ao container
+- [x] **JWT**: Autenticação obrigatória no WebSocket, verificação de `sub` e `exp`
+- [x] **Cleanup**: Container removido no `finally`, workdir limpo na desconexão
+- [x] **Docker client**: Inicialização lazy (`docker.from_env()`) — não cria conexão até necessário
+
+### 0.5 Recomendações (não bloqueantes)
+
+As seguintes medidas aumentariam a segurança mas não são requeridas para v1:
+
+1. **`--security-opt=no-new-privileges`**: Impedir que processos no container
+ adquiram novos privilégios via setuid/setgid. Não implementado atualmente.
+2. **`--security-opt=seccomp=`**: Perfil seccomp customizado mais
+ restritivo que o default do Docker (ex: bloquear `ptrace`, `mount`).
+3. **`auto_remove=True`**: Usar remoção automática do Docker em vez de remoção
+ manual no `finally` — mais idiomático e reduz chance de leak se o processo
+ Python for morto antes do `finally`.
+4. **gVisor / Firecracker**: Para isolamento mais forte (v2), considerar runtime
+ com kernel em userspace (`runsc`) ou micro-VM (`firecracker-containerd`).
+5. **Rate limit no Nginx**: Adicionar camada de rate limiting no reverse proxy
+ (pré-backend) para proteção adicional contra DDoS.
+6. **Monitoramento**: Adicionar métrica `simples_active_sandboxes` com alerta se
+ > 50 containers simultâneos.
