-# Feature Request: Real-time Logging & UI Refinement
-
-## 1. Context & Objective
-Users currently experience download failures without sufficient context or error details, making troubleshooting difficult.
-The objective is to introduce a dedicated **Logs System** within the application to capture, display, and persist detailed execution logs from the `yt-dlp` process.
-Additionally, the application's sidebar layout requires balancing for better UX.
-
-## 2. Requirements
-
-### 2.1. Backend (Rust) - Logging Infrastructure
-*   **Stream Capture**: The `downloader` module must capture both `STDOUT` (progress) and `STDERR` (errors/warnings) from the `yt-dlp` process.
-*   **Event Emission**: Emit a new Tauri event `download-log` to the frontend in real-time.
-    *   Payload: `{ id: String, message: String, level: 'info' | 'error' | 'debug' }`
-*   **Persistence (Optional but Recommended)**: Ideally, write logs to a local file (e.g., `logs/{date}.log` or `logs/{task_id}.log`) for post-mortem analysis. *For this iteration, real-time event emission is priority.*
-
-### 2.2. Frontend - Logs View
-*   **New Route**: `/logs`
-*   **UI Layout**:
-    *   A dedicated **Logs Tab** in the main navigation.
-    *   A console-like view displaying a stream of log messages.
-    *   Filters: Filter by "Task ID" or "Level" (Error/Info).
-    *   **Real-time**: The view must update automatically as new log events arrive.
-    *   **Detail**: Failed downloads must show the specific error message returned by `yt-dlp` (e.g., "Sign in required", "Video unavailable").
-
-### 2.3. UI/UX - Sidebar Refactoring
-*   **Reordering**:
-    *   **Top Section**: Home (Downloader), History.
-    *   **Bottom Section**: Logs, Settings.
-*   **Removal**: Remove the "Version Number" text from the bottom of the sidebar (it can be moved to the Settings page if needed, or just removed as requested).
-
-## 3. Implementation Steps
-
-### Step 1: Rust Backend Updates
-*   Modify `src-tauri/src/downloader.rs`:
-    *   Update `download_video` to spawn the process with `Stdio::piped()` for both stdout and stderr.
-    *   Use `tokio::select!` or separate tasks to read both streams concurrently.
-    *   Emit `download-log` events for every line read.
-    *   Ensure the final error message (if exit code != 0) is explicitly captured and returned/logged.
-
-### Step 2: Frontend Store & Logic
-*   Create `src/stores/logs.ts`:
-    *   State: `logs: LogEntry[]`.
-    *   Action: `addLog(entry)`.
-    *   Listener: Listen for `download-log` events globally.
-
-### Step 3: Frontend UI
-*   Create `src/views/Logs.vue`:
-    *   Display logs in a scrollable container.
-    *   Style error logs in red, info in gray/white.
-*   Update `src/App.vue`:
-    *   Add the `FileText` (or similar) icon for Logs.
-    *   Refactor the sidebar Flexbox layout to push Logs and Settings to the bottom.
-    *   Remove the version footer.
-*   Update `src/router/index.ts` to include the new route.
-
-## 4. Success Criteria
-*   When a download fails, the user can go to the "Logs" tab and see the exact error output from `yt-dlp`.
-*   The sidebar looks balanced with navigation items split between top and bottom.

-# Project: StreamCapture (Tauri + Vue 3 YouTube Downloader)
-
-## 1. Context & Objective
-You are an expert Full-Stack Rust/TypeScript developer specializing in Tauri v2 application development.
-Your task is to build a cross-platform (Windows & macOS) desktop application named "StreamCapture" in the current directory.
-The app is a GUI wrapper for `yt-dlp`, but unlike standard sidecar implementations, it must manage the `yt-dlp` binary externally (in the user's AppData directory) to allow for frequent updates without rebuilding the app.
-
-**Tech Stack:**
-- **Core:** Tauri v2 (Rust)
-- **Frontend:** Vue 3 (Composition API, `<script setup>`)
-- **Build Tool:** Vite
-- **Styling:** Tailwind CSS (Mobile-first, Modern UI)
-- **State Management:** Pinia
-- **Icons:** Lucide-vue-next
-- **HTTP Client (Rust):** `reqwest` (for downloading yt-dlp)
-
----
-
-## 2. Core Architecture & Workflow
-
-### 2.1. External Binary Management (Crucial)
-Since `yt-dlp` updates frequently, we **do NOT** bundle it inside the binary.
-1.  **Location:** The app must utilize the system's local data directory (e.g., `%APPDATA%/StreamCapture/bin` on Windows, `~/Library/Application Support/StreamCapture/bin` on macOS).
-2.  **Initialization:** On app launch, the Rust backend must check if `yt-dlp` exists in that directory.
-3.  **Auto-Download:** If missing, download the correct binary from the official GitHub releases (`yt-dlp.exe` for Win, `yt-dlp_macos` for Mac).
-4.  **Permissions:** On macOS, apply `chmod +x` (0o755) to the downloaded binary immediately.
-5.  **Execution:** Use Rust's `std::process::Command` to execute this specific binary using its absolute path.
-
-### 2.2. Configuration Persistence
--   File: `settings.json` in the app data directory.
--   Fields:
-    -   `download_path`: string (Default: System Download Dir)
-    -   `theme`: 'light' | 'dark' | 'system' (Default: system)
-    -   `last_updated`: timestamp (for yt-dlp check)
-
-### 2.3. History Persistence
--   File: `history.json`.
--   Stores a list of completed or failed downloads (metadata, status, timestamp, file path).
-
----
-
-## 3. Rust Backend Specifications (`src-tauri/src/lib.rs` & Modules)
-
-Create specific commands to handle logic securely. Avoid exposing raw shell execution to the frontend.
-
-### Module: `ytdlp_manager`
--   **`init_ytdlp()`**: Checks existence. If missing, downloads it. Returns status.
--   **`update_ytdlp()`**: Runs `yt-dlp -U`.
--   **`get_version()`**: Returns current version string.
-
-### Module: `downloader`
--   **`fetch_metadata(url: String)`**:
-    -   Runs `yt-dlp --dump-single-json --flat-playlist [url]`.
-    -   **Logic:** If it's a playlist, return a list of video objects (id, title, thumbnail, duration). If single video, return one object.
-    -   **Important:** Do NOT download media yet.
--   **`download_video(url: String, options: DownloadOptions)`**:
-    -   **Options Struct:** `{ is_audio_only: bool, quality: String, output_path: String }`
-    -   **Process:** Spawns a command. Emits Tauri Events (`download-progress`) to frontend with percentage and speed.
-
-### Module: `storage`
--   Helper functions to read/write `settings.json` and `history.json`.
-
----
-
-## 4. Frontend Specifications (Vue 3 + Tailwind)
-
-### 4.1. UI Layout
--   **Sidebar:** Navigation (Home/Download, History, Settings).
--   **Header:** Theme toggle, App status (checking yt-dlp...).
--   **Main Content:** Dynamic view based on route.
-
-### 4.2. Views
-
-#### A. Home View (The Downloader)
-1.  **Input Area:** Large, modern input box for URL. "Analyze" button.
-2.  **Selection Area (Conditional):**
-    -   Appears after "Analyze" succeeds.
-    -   Shows thumbnail(s) and title(s).
-    -   If Playlist: Show list of items with checkboxes (Select All / Select None).
-3.  **Options Panel:**
-    -   **Format:** Dropdown (Best Video+Audio, 1080p, 720p, 480p).
-    -   **Mode:** Toggle Switch (Video / Audio Only).
-4.  **Action:** Big "Download" button.
-5.  **Progress:** Progress bars for active downloads.
-
-#### B. History View
--   Table/List of past downloads.
--   Columns: Thumbnail (small), Title, Date, Format, Status (Success/Fail).
--   Actions: "Open File Location", "Delete Record" (Icon), "Clear All" (Button at top).
-
-#### C. Settings View
--   **Download Path:** Input field + "Browse" button (use Tauri `dialog` API).
--   **Yt-dlp:** Show current version. Button "Check for Updates".
--   **Theme:** Radio buttons (Light/Dark/System).
-
-### 4.3. State Management (Pinia stores)
--   `useSettingsStore`: Loads/saves config. Handles theme applying (adding `.dark` class to `html`).
--   `useQueueStore`: Manages active downloads and progress events.
-
----
-
-## 5. Visual Design Guidelines (Tailwind)
--   **Theme:**
-    -   **Light Mode:** White/Gray-50 background, Zinc-900 text, Primary Blue-600.
-    -   **Dark Mode:** Zinc-950 background, Gray-100 text, Primary Blue-500.
--   **Components:**
-    -   Rounded corners (`rounded-xl`).
-    -   Subtle shadows (`shadow-sm`, `shadow-md`).
-    -   Input fields with focus rings.
-    -   Transitions for hover states and page switches.
-
----
-
-## 6. Implementation Steps for Gemini
-Please generate the code in the following order. **Ensure all files include `// filepath: ...` comments.**
-
-1.  **Rust Setup:**
-    -   `Cargo.toml` (dependencies: reqwest, serde, serde_json, tokio, etc.).
-    -   `src-tauri/src/lib.rs`: Main entry with command registration.
-    -   `src-tauri/src/ytdlp.rs`: The download/update logic.
-    -   `src-tauri/src/commands.rs`: The Tauri commands exposed to frontend.
-2.  **Frontend Setup:**
-    -   `package.json`: deps (pinia, vue-router, lucide-vue-next, tailwindcss, autoprefixer, postcss).
-    -   `src/style.css`: Tailwind directives.
-    -   `src/stores/...`: Pinia stores.
-    -   `src/components/...`: Reusable UI components (Input, Button, Card).
-    -   `src/views/...`: The main pages.
-    -   `src/App.vue`: Main layout.
-3.  **Configuration:**
-    -   `tailwind.config.js`: Dark mode config.
-    -   `src-tauri/capabilities/default.json`: **CRITICAL**. Configure permissions to allow accessing `app_data_dir` and the network scope.
-
-## 7. Testing Requirements
--   Create a basic Rust test in `src-tauri/src/ytdlp.rs` that verifies it can construct the correct path for the binary based on OS.
--   Ensure Vue components handle "Loading" states gracefully (skeletons or spinners).
-
----
-
-**IMPORTANT NOTE ON PERMISSIONS:**
-Since we are using `std::process::Command` directly in Rust, we do not need to configure the strict `shell` scope in `tauri.conf.json`, but we MUST ensure the App Data directory is writable.
-
-Start by generating the Rust backend logic first, as the frontend depends on these commands.

-# Feature Specification: QuickJS Runtime Integration for yt-dlp
-
-## 1. Context & Objective
-`yt-dlp` increasingly relies on a JavaScript runtime to execute complex decryption scripts (e.g., signature extraction) required by YouTube and other platforms. Without a JS runtime, downloads may fail or be throttled.
-The objective is to automatically manage the **QuickJS** runtime binary (download, update, store) alongside the existing `yt-dlp` binary and configure the download process to utilize it via environment variable injection.
-
-## 2. Technical Requirements
-
-### 2.1. Binary Management
-The application must manage the QuickJS binary lifecycle identically to how it currently handles `yt-dlp`.
-
-*   **Source Repository:** [https://github.com/quickjs-ng/quickjs](https://github.com/quickjs-ng/quickjs)
-*   **Storage Location:** The user's AppData `bin` directory (same as `yt-dlp`).
-    *   Windows: `%APPDATA%\StreamCapture\bin\`
-    *   macOS: `~/Library/Application Support/StreamCapture/bin/`
-*   **Unified Naming on Disk:**
-    Regardless of the source filename, the binary must be renamed upon saving to ensure consistent invocation:
-    *   **Windows:** `qjs.exe`
-    *   **macOS:** `qjs`
-
-### 2.2. Download & Update Logic
-*   **Check:** On app launch (or `init_ytdlp`), check if `qjs` exists.
-*   **Download:** If missing, fetch the appropriate asset from the latest GitHub release of `quickjs-ng/quickjs`.
-    *   *Note:* Logic must detect OS/Arch to pick the correct asset (e.g., `windows-x86_64`, `macos-x86_64/arm64`).
-*   **Permissions:** On macOS/Linux, ensure `chmod +x` is applied.
-*   **Update:** When `update_ytdlp` is triggered, also check/redownload the latest `qjs` binary.
-
-### 2.3. Execution & Environment Injection
-To enable `yt-dlp` to find the `qjs` binary without hardcoding absolute paths in the flags (which can be fragile), we will modify the **subprocess environment**.
-
-*   **Command Flag:** Always pass `--js-runtime qjs` to the `yt-dlp` command.
-*   **Environment Modification:**
-    Before spawning the `yt-dlp` child process in Rust, dynamically modify its `PATH` environment variable.
-    *   **Action:** Prepend the absolute path of the application's `bin` directory to the system `PATH`.
-    *   **Result:** When `yt-dlp` looks for `qjs`, it will find it in the injected `PATH`.
-
-## 3. Implementation Plan
-
-### Step 1: Refactor `src-tauri/src/ytdlp.rs`
-*   Rename file/module to `src-tauri/src/binary_manager.rs` (Optional, or just expand `ytdlp.rs`).
-*   Add constants/functions for QuickJS:
-    *   `get_qjs_binary_name()`
-    *   `download_qjs()`: Similar logic to `download_ytdlp` but parsing QuickJS release assets.
-
-### Step 2: Update `src-tauri/src/commands.rs`
-*   Update `init_ytdlp` to initialize **both** binaries.
-*   Update `update_ytdlp` to update **both** binaries.
-
-### Step 3: Update `src-tauri/src/downloader.rs`
-*   In `download_video` and `fetch_metadata`:
-    1.  Resolve the absolute path to the `bin` directory.
-    2.  Read the current system `PATH`.
-    3.  Construct a new `PATH` string: `bin_dir + delimiter + system_path`.
-    4.  Configure the `Command`:
-        ```rust
-        Command::new(...)
-            .env("PATH", new_path)
-            .arg("--js-runtime")
-            .arg("qjs")
-            ...
-        ```
-
-## 4. Acceptance Criteria
-1.  **File Existence:** `qjs.exe` (Win) or `qjs` (Mac) appears in the `bin` folder after app startup.
-2.  **Process Execution:** The logs show `yt-dlp` running successfully.
-3.  **Verification:** If a specific video requires JS interpretation (often indicated by slow downloads or errors without JS), it proceeds smoothly.
-4.  **Clean Logs:** No "PhantomJS not found" or "JS engine not found" warnings in the logs.

-# QuickJS Binary Source Update
-
-## 1. Context
-The current `quickjs-ng` runtime is proving too slow for our needs. We need to switch to the original QuickJS runtime provided by Bellard.
-
-## 2. Source Details
-*   **Base URL:** `https://bellard.org/quickjs/binary_releases/`
-*   **Versioning:** Use `LATEST.json` at the base URL to find the latest version and filename.
-    *   Format: `{"version":"2024-01-13","files":{"quickjs-win-x86_64.zip":"quickjs-win-x86_64-2024-01-13.zip", ...}}`
-*   **Target Files:**
-    *   **Windows:** Look for key `quickjs-win-x86_64.zip`.
-    *   **macOS:** Look for key `quickjs-cosmo-x86_64.zip` (Cosmo builds are generally portable). *Wait, need to confirm if macos specific builds exist or if cosmo is the intended one for unix-like.*
-    *   *Correction*: Bellard's page lists `quickjs-macos-x86_64.zip`? Let's check LATEST.json first. Assuming `quickjs-cosmo` might be Linux/Universal. Let's fetch `LATEST.json` to be sure.
-
-## 3. Implementation Changes
-*   **`src-tauri/src/binary_manager.rs`**:
-    *   Update `QJS_REPO_URL` to `https://bellard.org/quickjs/binary_releases`.
-    *   Add logic to fetch `LATEST.json` first.
-    *   Parse the JSON to get the actual filename for the current OS.
-    *   Download the ZIP file.
-    *   Extract the binary (`qjs.exe` or `qjs`) from the ZIP.
-    *   Rename it to our internal standard (`quickjs.exe` / `quickjs`).
-
-## 4. Verification
-*   Re-run tests.
-*   Ensure `update_quickjs` flows correctly with the new logic.

-# Feature Request: Advanced Playlist Parsing & Mix Handling
-
-## Context
-We are upgrading the **StreamCapture** application. Currently, the app only supports parsing standard single video URLs.
-We need to implement robust support for **Standard Playlists** and **YouTube Mixes (Radio)**, while solving performance issues and thumbnail loading errors.
-
-## Problem Statement
-1.  **Playlists (`/playlist?list=...`)**: Fails to parse entries or hangs because it attempts to resolve full metadata for every video. Thumbnails are missing.
-2.  **Mixes (`/watch?v=...&list=RD...`)**: Currently fails or behaves unpredictably.
-3.  **UI/UX**: Users need a specific choice when encountering a "Mix" link:
-    * **Option A (Default):** Treat it as a single video (ignore the list).
-    * **Option B:** Parse the Mix as a playlist (limit to top 20 items).
-
-## Technical Requirements
-
-### 1. Rust Backend Refactoring (`src-tauri/src/ytdlp.rs`)
-
-Refactor the `fetch_metadata` command to use a unified, efficient parsing strategy.
-
-#### A. Command Construction
-For **ALL** metadata fetching, use the `--flat-playlist` flag to prevent deep extraction (which causes the hang).
-
-**Base Command:**
-```bash
-yt-dlp --dump-single-json --flat-playlist --no-warnings [URL]
-```
-
-#### B. Handling Different URL Types
-1. Single Video:
-    - `yt-dlp` returns a single JSON object with `_type: "video"` (or no type).
-    - Action: Wrap it in a list of 1.
-
-2. Standard Playlist:
-    - `yt-dlp` returns `_type: "playlist"` with an `entries` array.
-    - Action: Map the `entries` to our `Video` struct.
-
-3. Mix / Radio (Infinite List):
-    - Condition: If the frontend flags this request as a "Mix Playlist scan".
-    - Modification: Add flag --playlist-end 20 to the command.
-    - Reason: Mixes are infinite; we must cap them.
-
-#### C. Data Normalization & Thumbnail Fallback
-
-When using `--flat-playlist`, the `entries` often lack full `thumbnail` URLs or return webp formats that might not render immediately.
-
-- Logic: If the `thumbnail` field is missing or empty in an entry, construct it manually using the ID:
-    - https://i.ytimg.com/vi/{video_id}/mqdefault.jpg
-
-### 2. Frontend Logic (`src/views/Home.vue` & Stores)
-
-#### A. URL Detection & User Choice
-
-Before sending the URL to Rust, analyze the string:
-
-1. Regex Check: Detect if the URL contains both `v=` AND `list=` (typical for Mixes).
-
-2. New UI Element:
-    - If a Mix link is detected, show a **Checkbox** or **Toggle** near the "Analyze" button.
-    - Label: "Scan Playlist (Max 20)"
-    - Default State: Unchecked (Off).
-
-3. Submission Logic:
-    - If Unchecked (Default): Strip the `&list=...` parameter from the URL string before calling Rust. Treat it as a pure single video.
-    - If Checked: Keep the full URL and pass a flag (e.g., `is_mix: true`) to the Rust backend (or handle the logic to request the top 20).
-
-#### B. Displaying Results
-
-- Ensure the "Selection Area" can render a list of cards whether it contains 1 video or 20 videos.
-- If it's a playlist, show a "Select All" / "Deselect All" control.
-
-## Implementation Plan
-
-### Step 1: Rust Structs Update
-
-Update the Serde structs in `ytdlp.rs` to handle the `flat-playlist` JSON structure.
-
-```rust
-// Example structure hint
-struct YtDlpResponse {
-    _type: Option<String>,
-    entries: Option<Vec<VideoEntry>>,
-    // ... fields for single video fallback
-    id: Option<String>,
-    title: Option<String>,
-}
-
-struct VideoEntry {
-    id: String,
-    title: String,
-    duration: Option<f64>,
-    thumbnail: Option<String>, // Might be missing
-}
-```
-
-### Step 2: Rust Logic Update
-
-Modify `command::fetch_metadata`.
-
-- Accept an optional argument `parse_mix_playlist: bool`.
-- If `true`, append `--playlist-end 20`.
-- Implement the thumbnail fallback logic (if `thumbnail` is None, use `i.ytimg.com`).
-
-### Step 3: Frontend Update
-
-- Add the "Mix Detected" logic in `Home.vue`.
-- Add the toggle UI.
-- Update the `analyze` function to handle URL stripping vs. passing through based on the toggle.
-
-## Deliverables
-
-Please rewrite the necessary parts of `src-tauri/src/ytdlp.rs`, `src-tauri/src/commands.rs`, and `src/views/Home.vue` to implement this logic.
