 # Plano de Implementação: Integração llama.cpp e Download Hugging Face
 ## Contexto Arquitetural
 O projeto atualmente usa Ollama como runtime de modelos via HTTP (`http://localhost:11434`). O chat streaming é feito através de `chat_stream` que chama `OllamaClient`. Modelos são baixados via `pull_model` que usa a API do Ollama. Existe suporte básico para instalar modelos GGUF locais via `install_gguf_model`.
 **Decisão arquitetural:** Implementar runtime dual (Ollama + llama.cpp nativo) com abstração no backend Rust para permitir alternância transparente no frontend.
 ## Estrutura de Armazenamento
 - **Modelos Ollama:** `~/.ollama/models` (Linux/Mac) ou `%USERPROFILE%\.ollama\models` (Windows)
 - **Modelos llama.cpp nativo:** Estrutura hierárquica em `{app_data_dir}/models/gguf/{repo_owner}/{repo_name}/{quantization}/model.gguf`
  - Exemplo: `~/.local/share/OllaHub/models/gguf/TheBloke/Mistral-7B-Instruct-v0.2-GGUF/Q4_K_M/mistral-7b-instruct-v0.2.Q4_K_M.gguf`
 - **Cache de metadados:** `{app_data_dir}/cache/huggingface_models.json`
 - **Cross-platform paths:**
  - Windows: `%APPDATA%\Roaming\com.ollahub.app\models\gguf`
  - Linux: `~/.local/share/com.ollahub.app/models/gguf`
  - macOS: `~/Library/Application Support/com.ollahub.app/models/gguf`
 ## Fase 1: Backend - Download Direto Hugging Face
 ### 1.1 Módulo de Download (`src-tauri/src/huggingface_download.rs`)
 **Contrato técnico:**
 ```rust
 pub struct HuggingFaceModel {
    pub id: String,
    pub filename: String,
    pub size: u64,
    pub quantization: String, // Q4_K_M, Q5_K_S, etc.
    pub sha256: Option<String>,
 }
 pub async fn download_gguf_model(
    app_handle: AppHandle,
    model_id: String,
    filename: String,
    quantization_filter: Option<String>,
    window: Option<Window>,
 ) -> Result<PathBuf, String>
 ```
 **Implementação:**
 - Usar `reqwest` com streaming (já presente no `Cargo.toml`)
 - API Hugging Face: `https://huggingface.co/api/models/{model_id}/tree/main`
 - Download direto: `https://huggingface.co/{model_id}/resolve/main/{filename}`
 - Emitir eventos `download-progress` (reutilizar estrutura existente de `pull_model_impl_window`)
 - **Validação SHA256 obrigatória** quando disponível no Hugging Face (usar `sha2` já presente)
 - Retry logic com backoff exponencial (3 tentativas)
 - **Rate limiting:** Tratar 429 Too Many Requests com `Retry-After` header
 - **Resume de download:** Verificar arquivo parcial e continuar de onde parou
 **Arquivos:**
 - Criar `src-tauri/src/huggingface_download.rs`
 - Adicionar comando `download_gguf_model` em `lib.rs`
 ### 1.2 Busca de Modelos (`list_huggingface_gguf_models`)
 **Contrato:**
 ```rust
 pub async fn list_huggingface_gguf_models(
    query: Option<String>,
    quantization: Option<String>,
 ) -> Result<Vec<HuggingFaceModel>, String>
 ```
 **Implementação:**
 - Usar API pública do Hugging Face: `https://huggingface.co/api/models?search={query}&filter=gguf`
 - Filtrar por arquivos `.gguf` no tree
 - Cache local com TTL de 1 hora (evitar requests repetidos)
 - **Extrair quantização do filename** (regex corrigido: `[._-](Q\d+_?[KM]?_?[MS]?|[FI]P?\d+)[._-]`)
  - Suporta: `Q4_K_M`, `Q5_0`, `F16`, `FP32`, etc.
 **Arquivos:**
 - Adicionar função em `huggingface_download.rs`
 - Comando `list_huggingface_gguf_models` em `lib.rs`
 ### 1.3 Cache de Metadados
 **Estrutura:**
 - Arquivo JSON em `{app_data_dir}/cache/huggingface_models.json`
 - Estrutura: `{ "models": [...], "last_updated": "ISO8601" }`
 - Atualizar cache apenas se `last_updated` > 1 hora
 ## Fase 2: Backend - Integração llama.cpp
 ### 2.1 Dependências (`Cargo.toml`)
 **Correção crítica:** Usar `llama_cpp` (edgenai) versão 0.4 em vez de `llama-cpp-rs` 0.2
 ```toml
 [features]
 default = ["llama-cpp"]
 llama-cpp = ["dep:llama_cpp"]
 dev-no-llama = []  # Skip llama.cpp em dev builds (builds 30-45 min podem ser lentos)
 [dependencies]
 llama_cpp = { version = "0.4", optional = true }
 # Features condicionais por OS (Metal/CUDA são mutuamente exclusivos)
 [target.'cfg(target_os = "macos")'.dependencies]
 llama_cpp = { version = "0.4", features = ["metal"], optional = true }
 [target.'cfg(all(unix, not(target_os = "macos")))'.dependencies]
 llama_cpp = { version = "0.4", features = ["cuda"], optional = true }
 [target.'cfg(target_os = "windows")'.dependencies]
 llama_cpp = { version = "0.4", features = ["cuda"], optional = true }
 # Dependência para parsing de metadados GGUF
 gguf = "0.1"
 lru = "0.12"  # Para LRU cache de modelos carregados
 ```
 **Build considerations:**
 - `llama_cpp` compila `llama.cpp` via build script
 - **Tempo de build:** 30-45 min em máquinas mais fracas (não 10-15 min)
 - Feature flag `dev-no-llama` permite builds rápidos em desenvolvimento
 - Requer CMake/Ninja instalados (documentar no README)
 ### 2.2 Gerenciamento de Estado (`AppState`)
 **Estrutura (com LRU cache para prevenir memory leaks):**
 ```rust
 use lru::LruCache;
 pub struct LlamaCppState {
    models: Arc<Mutex<LruCache<String, LlamaModel>>>,  // Limite de 3 modelos
    default_params: LlamaParams,
 }
 impl LlamaCppState {
    pub fn new() -> Self {
        Self {
            models: Arc::new(Mutex::new(LruCache::new(3.try_into().unwrap()))),
            default_params: LlamaParams::default(),
        }
    }
 }
 pub struct LlamaModel {
    path: PathBuf,
    context: Option<LlamaContext>, // Lazy loading
    metadata: ModelMetadata,
 }
 ```
 **Arquivos:**
 - Criar `src-tauri/src/llama_cpp_state.rs`
 - Registrar state em `main()` via `.manage()`
 ### 2.3 Comando de Chat Streaming (`chat_stream_native`)
 **Contrato:**
 ```rust
 #[command]
 async fn chat_stream_native(
    window: Window,
    app_handle: AppHandle,
    session_id: Option<String>,
    messages: Vec<Message>,
    model_path: String,
    system_prompt: Option<String>,
    params: Option<LlamaParams>,
 ) -> Result<String, String>
 ```
 **Implementação:**
 - Carregar modelo lazy (verificar se já está em `AppState`)
 - Usar `llama-cpp-rs` para streaming de tokens
 - Emitir eventos `chat-token` (mesmo formato que `chat_stream` atual)
 - Reutilizar lógica de salvamento em DB existente
 - Parâmetros: `n_gpu_layers`, `n_ctx`, `threads` (configuráveis via settings)
 **Arquivos:**
 - Criar `src-tauri/src/llama_cpp_chat.rs`
 - Comando em `lib.rs`
 - Integrar com `ProcessingState` existente
 ### 2.4 Configuração de Parâmetros
 **Settings store (frontend):**
 - Adicionar `llamaCppParams` em `settings-store.ts`:
  ```typescript
  llamaCppParams: {
    nGpuLayers: number;
    nCtx: number;
    threads: number;
  }
  ```
 **Backend:**
 - Struct `LlamaParams` serializável
 - Valores padrão: `n_gpu_layers: 0` (CPU), `n_ctx: 4096`, `threads: auto`
 ## Fase 3: Backend - Listagem Local
 ### 3.1 Scan de Arquivos GGUF (`list_local_gguf_models`)
 **Contrato:**
 ```rust
 #[command]
 fn list_local_gguf_models(app_handle: AppHandle) -> Result<Vec<LocalGgufModel>, String>
 ```
 **Implementação:**
 - Scan recursivo em `{app_data_dir}/models/gguf/` (estrutura hierárquica)
 - Usar `walkdir` (já presente)
 - **Parsing de metadados GGUF usando crate `gguf`:**
  ```rust
  use gguf::GGUFFile;
  pub fn extract_gguf_metadata(path: &Path) -> Result<GgufMetadata, String> {
      let file = std::fs::File::open(path).map_err(|e| e.to_string())?;
      let gguf = GGUFFile::parse(file).map_err(|e| e.to_string())?;
      Ok(GgufMetadata {
          architecture: gguf.header.metadata.get("general.architecture"),
          quantization: gguf.header.metadata.get("general.quantization_version"),
          parameter_count: gguf.header.metadata.get("general.parameter_count"),
      })
  }
  ```
 - Extrair metadados:
  - Tamanho do arquivo
  - Quantização do filename (regex corrigido)
  - **Arquitetura via parsing de header GGUF** (não inferir do filename)
 - Cache de metadados para evitar re-scan frequente
 **Estrutura de retorno:**
 ```rust
 pub struct LocalGgufModel {
    pub path: String,
    pub name: String,
    pub size: u64,
    pub quantization: Option<String>,
    pub architecture: Option<String>,
 }
 ```
 **Arquivos:**
 - Função em `lib.rs` ou módulo separado `src-tauri/src/local_models.rs`
 ### 3.2 Detecção Automática
 - Ao baixar modelo do Hugging Face, adicionar à lista local automaticamente
 - Verificar integridade (tamanho, extensão) antes de listar
 ## Fase 4: Frontend - UI Experimental
 ### 4.1 Settings Store - Runtime Selection
 **Modificações em `store/settings-store.ts`:**
 ```typescript
 runtime: 'ollama' | 'llama-cpp';
 llamaCppParams: { nGpuLayers: number; nCtx: number; threads: number };
 setRuntime: (runtime: 'ollama' | 'llama-cpp') => void;
 setLlamaCppParams: (params: Partial<LlamaCppParams>) => void;
 ```
 ### 4.2 Toggle de Runtime (`components/settings/`)
 **Componente:**
 - Toggle switch "Usar llama.cpp nativo"
 - **Indicador visual melhorado** com ícone + tooltip:
  ```tsx
  <Badge variant={runtime === 'ollama' ? 'default' : 'secondary'}>
    {runtime === 'ollama' ? (
      <>🦙 Ollama</>
    ) : (
      <>⚡ llama.cpp (nativo)</>
    )}
  </Badge>
  <Tooltip>
    <TooltipContent>
      {runtime === 'ollama' 
        ? 'Usando Ollama como runtime (requer servidor externo)'
        : 'Usando llama.cpp nativo (mais rápido, sem servidor externo)'}
    </TooltipContent>
  </Tooltip>
  ```
 - Desabilitar se nenhum modelo GGUF local disponível
 **Arquivos:**
 - Criar ou modificar `components/settings/runtime-settings-panel.tsx`
 ### 4.3 Seletor de Modelos Hugging Face
 **Componente:**
 - Input de busca
 - Lista de modelos com filtros de quantização (Q4, Q5, Q8)
 - Botão de download com progresso
 - Integrar com `DownloadContext` existente
 **Arquivos:**
 - Criar `components/chat/huggingface-model-selector.tsx`
 - Integrar em `components/chat/model-selector.tsx`
 ### 4.4 Página de Comparação
 **Componente experimental:**
 - Side-by-side: Ollama vs llama.cpp
 - Mesmo prompt, comparar latência e qualidade
 - Métricas: tokens/s, tempo total, uso de VRAM
 **Arquivos:**
 - Criar `app/benchmark/page.tsx` (opcional, pode ser feature flag)
 ### 4.5 Integração no Chat
 **Modificações em `hooks/use-chat.ts`:**
 - Verificar `runtime` do settings store
 - Chamar `chat_stream` ou `chat_stream_native` conforme runtime
 - Manter compatibilidade com código existente
 **Arquivos:**
 - Modificar `hooks/use-chat.ts`
 - Atualizar `app/chat/page.tsx` se necessário
 ## Decisões Técnicas
 ### Abordagem Ingênua vs Sênior
 | Aspecto | Ingênua | Sênior (Escolhida) |
 |---------|---------|-------------------|
 | Download | Polling de status | Streaming com eventos Tauri |
 | Estado de Modelos | Sem cache | **LRU cache com limite de 3 modelos** |
 | Integração Chat | Duplicar código | Abstração via enum Runtime |
 | Validação | Apenas tamanho | **SHA256 obrigatório quando disponível** + tamanho + **parsing header GGUF** |
 | Build llama.cpp | Sempre compilar | **Feature flags condicionais por OS + dev-no-llama** |
 | Rate Limiting | Sem tratamento | **Backoff + Retry-After header** |
 | Parsing Metadata | Inferir do filename | **Crate `gguf` para parsing correto** |
 ### Trade-offs
 - **Performance:** llama.cpp nativo pode ser 10-30% mais rápido que Ollama (sem overhead HTTP)
 - **Manutenção:** Duplicar lógica de chat aumenta complexidade; abstração Runtime reduz duplicação
 - **VRAM:** llama.cpp permite controle fino de `n_gpu_layers`; Ollama gerencia automaticamente
 ### Modos de Falha
 1. **Gargalo VRAM:** Modelos grandes podem não carregar; implementar fallback para CPU
   - **Solução:** Usar `sysinfo` crate para detectar VRAM disponível antes de carregar
 2. **Download interrompido:** Retry logic com resume (verificar se arquivo parcial existe)
 3. **Build llama.cpp falha:** Feature flag `dev-no-llama` para desabilitar em desenvolvimento
 4. **Latência de rede:** Cache agressivo de metadados do Hugging Face
 5. **Rate limiting Hugging Face:** Tratar 429 com `Retry-After` header
 6. **Concurrent downloads:** Limitar a 2 downloads paralelos com semáforo
 7. **Memory leaks:** LRU cache com limite de 3 modelos previne crescimento indefinido
 ### Antipadrões a Evitar
 - Não fazer polling de status de download (usar eventos)
 - Não carregar todos os modelos na inicialização (lazy loading)
 - Não duplicar lógica de streaming (abstrair Runtime)
 - Não hardcodar paths (usar `app_data_dir`)
 ## Ordem de Implementação (Reordenada)
 1. **Estrutura de diretórios e AppState** (fundação)
   - Criar `get_models_dir()` com paths cross-platform
   - Implementar `LlamaCppState` com LRU cache
 2. **Listagem local de GGUF** (valida estrutura)
   - `list_local_gguf_models()` com parsing via crate `gguf`
   - Cache de metadados
 3. **Download Hugging Face** (adiciona modelos)
   - `download_gguf_model()` com SHA256 obrigatório
   - Rate limiting e retry logic
 4. **Parsing de metadados GGUF** (enriquece listagem)
   - Integrar crate `gguf` para extrair arquitetura
 5. **Integração llama.cpp** (runtime)
   - `chat_stream_native()` com lazy loading
   - Detecção de VRAM via `sysinfo`
 6. **UI experimental** (camada final)
   - Toggle de runtime com indicador melhorado
   - Integração no `use-chat.ts`
 ## Validação
 **Comandos de teste (Windows PowerShell):**
 ```powershell
 # Verificar modelos baixados
 Get-ChildItem "$env:APPDATA\OllaHub\models\gguf" -Recurse -Filter "*.gguf"
 # Testar download (via Tauri command)
 # Usar DevTools do app para invocar: download_gguf_model
 ```
 **Comandos de teste (Linux Bash):**
 ```bash
 # Verificar modelos baixados
 find ~/.local/share/com.ollahub.app/models/gguf -name "*.gguf"
 # Testar build llama.cpp (com feature flag)
 cargo build --features llama-cpp  # Build completo
 cargo build --no-default-features --features dev-no-llama  # Build rápido (dev)
 # Verificar VRAM disponível (se NVIDIA)
 nvidia-smi --query-gpu=memory.free --format=csv
 ```
 ## Correções Críticas Aplicadas

-## 🌟 Why OllaHub?
+## What it is
-OllaHub is a powerful desktop application that orchestrates local Large Language Models (LLMs) through **Ollama**, providing a private, offline-capable workspace for research, analysis, and conversation. 
+OllaHub is a desktop chat app for the models you run with [Ollama](https://ollama.com). On first run it scans your hardware, recommends a model and downloads it. After that it chats with streaming, keeps history in a local SQLite database, and can add context from web search, MCP tools and scheduled tasks. The UI is Next.js inside a Tauri 2 window, and a Rust backend does the work.
-Unlike standard chat interfaces, OllaHub executes **complex research workflows** by decomposing queries, performing parallel web scraping, and synthesizing context from multiple sources before generating responses—all while keeping your data 100% local and private.
+OllaHub is a client, not a model runtime. It talks to the Ollama API (default `http://localhost:11434`, configurable in Settings), tries to start Ollama when it is installed but stopped, and can download the Ollama installer when it is missing.
---
+## Why use it
-## ✨ Key Features
+- **Local by default.** Prompts go to your own Ollama, and chats live in `ollahub.db` in the app data directory, with FTS5 full-text search. Besides downloads (models, the embedding model, updates), web search is what reaches the internet.
 - **Web answers ranked on your machine.** Headless Chrome scrapes Google, Bing, Yahoo, DuckDuckGo and Startpage (order configurable), then local embeddings (`all-MiniLM-L6-v2` on ONNX Runtime) rank and prune the pages, with a BM25-like fallback when the embedding model is unavailable. A deep-research mode runs planning → searching → aggregating → validating → formulating.
 - **More than a chat box.** MCP servers run as child processes configured in `mcp_config.json`, their tools can be called from the chat, and cron tasks (search and summarize, notification, custom prompt) keep running in the background.
-### 🔍 Deep Research Pipeline
+**When not to use it:** if you want a finished, tested product (version `0.1.0`, no test suite), a model runtime of its own, or a server you can run without a desktop.
 OllaHub doesn't just answer; it researches. Our multi-stage pipeline includes:
 1. **Query Decomposition:** Uses the LLM to break complex queries into 3-5 atomic, search-optimized sub-queries.
 2. **Parallel Scraping:** Executes concurrent searches using headless Chrome and the DuckDuckGo metadata API.
 3. **Knowledge Aggregation:** Collects, deduplicates, and cleans content from multiple sources.
 4. **Context Condensation:** Applies relevance scoring (ONNX embeddings) and summarization to fit context within token limits.
 5. **Validation:** Verifies knowledge base sufficiency before response generation, with safety fallbacks.
-### 🛡️ Local-First & Privacy-Focused
+## How it works
 * **Ollama Integration:** Direct subprocess management for seamless local model execution.
 * **Local Semantic Search:** Powered by ONNX Runtime (`all-MiniLM-L6-v2` 384-dimensional embeddings) with no external API calls.
 * **Hybrid Storage:** Blazing fast SQLite (FTS5 for full-text search) with JSON fallbacks for backward compatibility and data safety.
-### 🔌 MCP (Model Context Protocol) Integration
+- **Frontend** (`app/`, `components/`, `hooks/`, `lib/`, `store/`): Next.js 16 with `output: 'export'`, React 19, Tailwind 4, Radix UI and Zustand. It calls the backend through Tauri `invoke` and events.
-Extensible by design. Connect external tools via MCP servers:
+- **Backend** (`src-tauri/src/`): `lib.rs` holds the commands for chat (`chat_stream`), models, the Ollama lifecycle, sessions, MCP, search, tasks, export and the installer. `db.rs` handles SQLite, `web_scraper.rs` the search engines, `embeddings.rs` the ranking, and `scheduler.rs` the cron tasks stored in `tasks.json`.
-* **Tool Discovery:** Automatic enumeration of available tools from running servers.
+- **Models:** list, delete and pull with progress, install a local `.gguf` file, and get a recommendation for your hardware.
-* **Process Management:** Full lifecycle control (start, stop, restart) with health monitoring.
+- **System monitor:** CPU and RAM stats plus GPU VRAM, usage and temperature. GPU detection uses `wmic` and `nvidia-smi` on Windows and `lspci` on Linux.
-* **Tool Execution:** Runtime invocation of tools with direct result injection into the LLM context.
+- **Updates:** the Tauri updater checks automatically. Its endpoint in `src-tauri/tauri.conf.json` points to a GitHub Releases `latest.json`.
-### ⚡ Reactive & Customizable UI
+More notes: [`docs/updater-setup.md`](docs/updater-setup.md) (signing keys and updater) and [`docs/style-guide.md`](docs/style-guide.md) (UI spacing, radii, accessibility).
 Built with **React 19, Next.js 16, and Tailwind CSS**. Features smooth animations (Framer Motion), accessible primitives (Radix UI/Shadcn), resizable panels, and lightweight state management (Zustand).

+## Quick start
-## 🏗️ System Architecture
+No release is published on this repository yet, so build it locally. You need Node.js 20, pnpm 8, a stable Rust toolchain and the [Tauri 2 prerequisites](https://tauri.app/start/prerequisites/) (the versions come from the CI workflow). On Ubuntu the workflow also installs `libwebkit2gtk-4.1-dev libssl-dev libayatana-appindicator3-dev librsvg2-dev patchelf`. Ollama is needed at runtime.

 ## 🚀 Getting Started
 ### Prerequisites
 Before you begin, ensure you have the following installed:
 * **Node.js**: `v20.x` or later
 * **Rust**: `v1.77.2` or later
 * **pnpm**: Latest version (`npm install -g pnpm`)
 * **[Ollama](https://ollama.ai)**: Must be running locally on `http://localhost:11434`
 ### Installation & Development
 1. **Clone the repository:**
 ```bash
-git clone [https://github.com/evandrodevbr/OllaHub.git](https://github.com/evandrodevbr/OllaHub.git)
+git clone https://git.evandro.dev.br/evandro/OllaHub.git
 cd OllaHub
 ```
 2. **Install dependencies:**
 ```bash
 pnpm install
 pnpm tauri dev          # starts `pnpm dev` (Next.js on http://localhost:3000) inside the Tauri window
 pnpm tauri build        # runs `pnpm generate-changelog && pnpm build`, then bundles the installer
 pnpm lint               # ESLint
 pnpm bump-version       # patch | minor | major, optional --commit
 ```
 The workflow [`.github/workflows/release.yml`](.github/workflows/release.yml) builds `msi` (Windows), `dmg` (macOS, Apple Silicon and Intel) and `AppImage` (Linux) on pushes to `main`, `master` and `develop`, and publishes release `v<version>` on pushes to `main` or `master`.
-3. **Run in development mode:**
+> [!WARNING]
-```bash
+> **Two things the app does on its own.**
-pnpm tauri dev
+> 1. Opening the chat page pulls the small helper model **`qwen2.5:0.5b`** if it is not installed yet, used for automatic chat titles. Expect an extra download on first use.
 > 2. **Closing the window only hides it.** The close request is intercepted (`prevent_close`) so scheduled tasks keep running, but there is no tray icon to bring the window back yet; the tray step is still pending in [`IMPLEMENTATION_GUIDE.md`](IMPLEMENTATION_GUIDE.md).
-```
+## Project status
 Early: version `0.1.0`, 47 commits between 2025-10-27 and 2025-11-27, no automated tests (`package.json` defines `dev`, `build`, `start`, `lint`, `generate-changelog` and `bump-version`). Known limitations:
-*This starts the Next.js server (`localhost:3000`), builds the Rust backend, and launches the Tauri native window.*
+- **No tray icon yet:** closing the window hides it (see the warning above).
 - **"Start with the system" does nothing yet:** the setting only toggles a stored flag; the code has a `TODO` until `tauri-plugin-autostart` is configured.
 - **RAG inside `chat_stream` is not wired:** the `enable_rag` branch is commented out as `TODO`; the frontend assembles web context before the request.
 - **Embeddings outside Windows:** the ONNX Runtime library is downloaded automatically only on Windows. On macOS and Linux, provide it in the app data folder or on the system path, otherwise ranking falls back to BM25-like scoring.
 - **Unused leftovers:** `src-tauri/scripts/scraper.py` is not called by the Rust backend, and the 188 model files in `data/models/` are not referenced by the app code.
