 Observação sobre pnpm: a seção `overrides` do `pnpm-workspace.yaml` (fastify e undici com versão mínima de segurança) só é aplicada pelo pnpm 10 ou superior. Com pnpm 9 ela é ignorada.

+A sessão é identificada pelo header `x-session-id` (a interface guarda o id em `localStorage`). Erros observados: 400 para URL inválida (`{"error":"Invalid URL"}`), com protocolo que não seja http/https, apontando para endereço local ou privado, ou para download não pronto; 403 para task de outra sessão e 404 para task inexistente.

-## Verificação
+## Testes e desenvolvimento

-Não há testes automatizados neste repositório. O que existe de fato:
+```bash
+pnpm typecheck   # tsc nos dois pacotes
+pnpm lint        # eslint no web
+pnpm test        # vitest no server e no web
+pnpm build
+```

- `pnpm build` roda o `tsc` do server e `tsc -b && vite build` do web, e é o gate atual;
- `pnpm --filter web lint` roda o eslint (passa com 1 warning de `exhaustive-deps` em `SessionContext.tsx`);
- verificação manual executada em 14/09/2026 (Linux, Node 24.20.0, pnpm 12.4.1): `pnpm install` e `pnpm build` com exit 0; 13 checagens de API passando (`/health`, `/`, `/api/session`, `/api/queue` com URL inválida e válida, `/api/tasks`, `/api/download/:id`, 400/403/404 e `/stream` respondendo 410); download de 10 MB conferido por sha256 idêntico ao da origem; interface verificada em Chrome headless (sessão inicializada, task concluída e "Save to Disk" baixando o arquivo com o mesmo sha256).
-
-Adicionar testes automatizados é o próximo passo natural do projeto.
+Os testes do servidor cobrem a validação de URL e o bloqueio de IPs privados, o tratamento de redirects, a expiração de sessões (com remoção das tasks e dos arquivos) e a validação do id de sessão. Os do web cobrem os estados do componente `DownloadItem`. O mesmo conjunto roda no GitHub Actions (`.github/workflows/ci.yml`).

 ## Estado atual e limitações

 - Sessões e tasks ficam em memória: reiniciar o servidor perde a lista de tasks (os arquivos em disco são removidos pelo coletor depois de 1 hora).
- Sem autenticação: qualquer um que alcance o servidor pode enfileirar downloads. Coloque atrás de VPN, autenticação reversa ou firewall.
+- Sem autenticação: qualquer um que alcance o servidor pode enfileirar downloads (de destinos públicos). Coloque atrás de VPN, autenticação reversa ou firewall.
 - Não há retomada de download nem uso de `Range` no fluxo atual (o parâmetro `offset` do antigo `/stream` não existe mais).
 - Não há limite de tamanho, banda ou cota: um link muito grande ocupa o disco do servidor até a sessão expirar.
- URLs que não sejam http/https são aceitas na fila e falham depois com `status: "error"`.
- Sem CI configurada e sem arquivo de licença.
+- "Save to Disk" carrega o arquivo inteiro na memória do navegador (`blob()`) antes de salvar, o que pesa em arquivos muito grandes.
 - O diretório `.agent/` é scaffolding de ferramentas de IA e não é usado pela aplicação.

-## Documentação
-
-Não há documentação interna além deste README: `docs/PLAN.md` está vazio e `web/README.md` é o texto padrão do template do Vite.

-# React + TypeScript + Vite
-
-This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
-
-Currently, two official plugins are available:
-
- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Babel](https://babeljs.io/) (or [oxc](https://oxc.rs) when used in [rolldown-vite](https://vite.dev/guide/rolldown)) for Fast Refresh
- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
-
-## React Compiler
-
-The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
-
-## Expanding the ESLint configuration
-
-If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
-
-```js
-export default defineConfig([
-  globalIgnores(['dist']),
-  {
-    files: ['**/*.{ts,tsx}'],
-    extends: [
-      // Other configs...
-
-      // Remove tseslint.configs.recommended and replace with this
-      tseslint.configs.recommendedTypeChecked,
-      // Alternatively, use this for stricter rules
-      tseslint.configs.strictTypeChecked,
-      // Optionally, add this for stylistic rules
-      tseslint.configs.stylisticTypeChecked,
-
-      // Other configs...
-    ],
-    languageOptions: {
-      parserOptions: {
-        project: ['./tsconfig.node.json', './tsconfig.app.json'],
-        tsconfigRootDir: import.meta.dirname,
-      },
-      // other options...
-    },
-  },
-])
-```
-
-You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
-
-```js
-// eslint.config.js
-import reactX from 'eslint-plugin-react-x'
-import reactDom from 'eslint-plugin-react-dom'
-
-export default defineConfig([
-  globalIgnores(['dist']),
-  {
-    files: ['**/*.{ts,tsx}'],
-    extends: [
-      // Other configs...
-      // Enable lint rules for React
-      reactX.configs['recommended-typescript'],
-      // Enable lint rules for React DOM
-      reactDom.configs.recommended,
-    ],
-    languageOptions: {
-      parserOptions: {
-        project: ['./tsconfig.node.json', './tsconfig.app.json'],
-        tsconfigRootDir: import.meta.dirname,
-      },
-      // other options...
-    },
-  },
-])
-```

evandro	dee0771ac5	fix(server): bloqueia SSRF e path traversal na sessão e segue redirects - SSRF: /api/queue aceitava qualquer URL, inclusive localhost, rede privada e 169.254.169.254. Agora só http/https e, por padrão, nada de endereço local/privado (checagem na fila e no conector do undici, que cobre DNS rebinding e redirects). ALLOW_PRIVATE_NETWORK=true libera. - O header x-session-id virava nome de diretório sem validação; com ".." a expiração faria rmSync em server/. Agora só UUID é aceito. - Respostas 3xx eram salvas como se fossem o arquivo; agora segue até 5 redirects e trata 3xx restante como erro. - decodeURIComponent inválido no Content-Disposition derrubava o download. - web: useCallback em refreshTasks (corrige o warning exhaustive-deps).	2026-10-10 03:59:44 -03:00
evandro	bc9a43d6de	feat(web): exibe erros ao enfileirar e melhora acessibilidade e contraste - Mostra no formulário o erro devolvido pela API ao enfileirar (antes só ia ao console) e desabilita o botão durante o envio. - Adiciona aria-label no campo de URL, role=alert no erro e role=progressbar na barra. - Clareia a cor destructive (contraste do texto de erro sobre o fundo escuro ~2:1 para ~4,5:1). - Corrige o título da página (era 'web').	2026-10-10 03:56:37 -03:00
evandro	6fbc1222b4	perf(server): descarta as tasks de sessões expiradas e adiciona testes do servidor O Map de tasks em DownloadManager nunca removia entradas; em um servidor de longa duração ele crescia sem limite, mesmo com os arquivos da sessão já apagados. O SessionManager agora avisa quando destrói uma sessão e o DownloadManager descarta as tasks dela.	2026-10-10 03:56:15 -03:00
