+# Integrações Nativas do Transcript Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Implementar as integrações que faltavam no MVP: gerenciador real do modelo GGUF, captura de áudio WAV, execução CrispASR, hotkey global e inserção/cópia com fallback cross-platform.
+
+**Architecture:** Manter cada integração atrás de um módulo pequeno. A UI chama comandos Tauri, os comandos consultam `ManagedAppState`, e integrações dependentes de SO retornam mensagens explícitas quando o ambiente limita a automação.
+
+**Tech Stack:** Tauri 2, Rust, CPAL, hound, reqwest, Tauri global-shortcut plugin, TypeScript.
+
+---
+
+## Task 1: Model manager real
+
+**Files:**
+- Modify: `src-tauri/src/models/mod.rs`
+- Modify: `src-tauri/src/ui_commands.rs`
+- Modify: `src-tauri/Cargo.toml`
+
+- [ ] Add URL de download do Hugging Face e resolução de diretório local.
+- [ ] Add validação por existência e tamanho mínimo/esperado.
+- [ ] Add comando `download_default_model` com escrita em arquivo temporário e rename atômico.
+- [ ] Testar status notInstalled/ready sem baixar o arquivo real.
+
+## Task 2: Captura real de áudio
+
+**Files:**
+- Modify: `src-tauri/src/audio/mod.rs`
+- Modify: `src-tauri/src/app_state.rs`
+- Modify: `src-tauri/src/ui_commands.rs`
+- Modify: `src-tauri/Cargo.toml`
+
+- [ ] Implementar gravador CPAL que escreve WAV via hound.
+- [ ] Guardar stream ativo no estado para manter gravação viva.
+- [ ] Stop finaliza WAV e retorna caminho.
+- [ ] Manter teste unitário de máquina de estados.
+
+## Task 3: Execução CrispASR
+
+**Files:**
+- Modify: `src-tauri/src/transcription/crispasr.rs`
+- Modify: `src-tauri/src/ui_commands.rs`
+- Modify: `src-tauri/tauri.conf.json`
+
+- [ ] Resolver binário via variável/env/config e depois sidecar empacotado.
+- [ ] Executar `crispasr -m <model> -f <audio>`.
+- [ ] Capturar stdout/stderr e retornar erro claro.
+- [ ] Parsear texto simples ou JSON quando disponível.
+
+## Task 4: Hotkey global
+
+**Files:**
+- Modify: `src-tauri/Cargo.toml`
+- Modify: `src-tauri/src/lib.rs`
+
+- [ ] Adicionar `tauri-plugin-global-shortcut`.
+- [ ] Registrar `Ctrl+Alt+Space` no setup.
+- [ ] Ao pressionar, mostrar/focar janela e emitir evento `hotkey-toggle-recording` para a UI.
+
+## Task 5: Inserção/cópia cross-platform
+
+**Files:**
+- Modify: `src-tauri/src/injection/mod.rs`
+- Modify: `src-tauri/src/ui_commands.rs`
+- Modify: `src-tauri/Cargo.toml`
+
+- [ ] Adicionar clipboard backend com `arboard`.
+- [ ] Implementar `request_insert_text` que sempre coloca o texto no clipboard.
+- [ ] Retornar mensagens por plataforma/display server.
+- [ ] Manter Wayland como parcial/manual.
+
+## Task 6: UI, CI e docs
+
+**Files:**
+- Modify: `src/app.ts`
+- Modify: `src/app.test.ts`
+- Modify: `.github/workflows/*.yml`
+- Modify: `README.md`
+
+- [ ] Mostrar status de modelo e botão de download.
+- [ ] Reagir ao evento de hotkey.
+- [ ] Atualizar CI Linux com `libasound2-dev`.
+- [ ] Rodar verificação final completa.
+
+## Verification
+
+Run:
+
+```bash
+npm run typecheck
+npm run test -- --run
+npm run build
+cargo test --manifest-path src-tauri/Cargo.toml
+npm run tauri:build
+```
+
+Expected: todos passam; build Windows gera MSI/NSIS no ambiente atual.
