chore(release): prepare Firelink 1.0.0

Add aria2 control epochs so delayed resume workers cannot unpause a transfer after a newer pause, remove, or reconfigure command wins.

Thread captured cookies into yt-dlp media runs, sanitize yt-dlp config values, reject malformed media headers, and preserve resumable media artifacts across transient retry backoff.

Cover the new queue epoch and media helper behavior with focused regression tests.

 # Changelog
 
-All notable changes to this project will be documented in this file.
+All notable changes to Firelink will be documented in this file.
 
 The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
 and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
 
+## [1.0.0] - 2026-07-04
+
+### Highlights
+- Firelink is now a cross-platform desktop download manager built with Rust, Tauri, React, and TypeScript.
+- macOS, Windows, and Linux release builds are prepared through native GitHub Actions runners.
+- The older macOS-only Swift app has been removed from the active product and replaced by the new desktop app.
+
+### New
+- Add full browser-to-desktop integration through Firelink Companion, including signed local requests, desktop identity checks, and automatic-capture protection.
+- Add a complete Add window for links captured from the browser, pasted manually, or extracted from media pages.
+- Add segmented direct downloads, media downloads, queue controls, scheduling, speed limits, and duplicate handling.
+- Add persistent downloads, categories, save-location settings, site logins, and safe redownload behavior.
+- Add native tray controls, notifications, completion sounds, sleep prevention, file reveal/open/trash actions, and OS keychain support where available.
+- Add built-in diagnostics for media engines, app logs, packaged-engine validation, and release smoke checks.
+
+### Improved
+- Rework the main window, settings, logs, Add window, download list, toasts, context menus, and table interactions for the new desktop interface.
+- Improve media extraction with better YouTube metadata loading, format filtering, size estimates, output names, progress, retries, and cleanup.
+- Improve download reliability on rate-limited servers, servers with broken range support, interrupted app sessions, and queue-concurrency changes.
+- Improve extension captures so browser downloads are resumed unless Firelink confirms the handoff.
+- Improve cross-platform packaging by bundling target-specific aria2, yt-dlp, FFmpeg, and Deno payloads.
+- Improve privacy by avoiding startup keychain prompts, redacting secrets from local persistence, and narrowing when browser cookies are forwarded.
+
+### Fixed
+- Fix stuck queued/downloading/completed states, stale aria2 dispatches, queue shrink behavior, retry caps, scheduler actions, and post-queue system actions.
+- Fix many Windows, Linux, and macOS packaging issues, including hidden helper consoles, AppImage engine handling, installer validation, and smoke-test timing.
+- Fix media child-process cleanup so paused, canceled, failed, or removed downloads do not leave stray processes or partial files behind.
+- Fix UI hangs, overflow, sorting, selection, animation, and contrast issues across the main list, Add window, settings, and log viewer.
+- Fix security issues around local server authentication, request signing, replay protection, private IP metadata checks, path ownership, header sanitization, and command execution boundaries.
+
+### Notes
+- This is a major release from `0.7.3`. Older Firelink Companion builds are not compatible with every 1.0 capture path; update the extension together with the desktop app.
+- macOS builds are unsigned and not notarized. Windows builds are unsigned. See [RELEASE.md](RELEASE.md) for distribution details.
+
+## [0.7.3] - 2026-06-11
+
+### New Features & Improvements
+- Add Deno to about credits and engines list.
+- Enhance speed and ETA display logic during pause and drop.
+- Accumulate track sizes to present a unified overall progress bar.
+
+### Fixes
+- Resolve unknown speed flickering and ultra-wide high-resolution detection.
+- Emit distinct status messages for individual tracks during download.
+- Pad overall progress total for first track to prevent 100% snapback.
+
+## [0.7.2] - 2026-06-11
+
+### Fixed
+- Prevented yt-dlp and JavaScript child processes from keeping metadata fetches or canceled downloads alive indefinitely.
+- Replaced the repeatedly extracted one-file yt-dlp build with a stable prewarmed runtime cache.
+- Bundled Deno so YouTube JavaScript challenges and formats above 720p do not depend on system-installed tools.
+- Stopped masking empty-format extraction failures and removed brittle forced YouTube client selection.
+
+### Changed
+- Pinned and checksum-verified yt-dlp, Deno, FFmpeg, aria2, and aria2's libraries for matching local and GitHub Actions builds.
+- Removed aria2's runtime dependency on Homebrew and configured its bundled CA certificate for direct and yt-dlp-delegated HTTPS downloads.
+- Added bounded network retries and optional aria2c acceleration for large direct media downloads.
+
+## [0.7.1] - 2026-06-11
+
+### Fixes
+- Increased the `yt-dlp` metadata extraction timeout to 120 seconds to properly handle YouTube's new JavaScript Proof-of-Work bot protection challenges.
+- Improved the `AddDownloadsView` UI to display the exact underlying error message during extraction failures rather than a generic masked string.
+
+### Security Fixes
+- Addressed multiple vulnerabilities identified in the v0.7.0 security audit.
+- Moved `yt-dlp` credential passing from CLI arguments to secure temporary configuration files to prevent process list leakage.
+- Enforced strict `0o600` POSIX permissions on `aria2c` temporary configuration files to protect generated RPC secrets.
+- Replaced the unauthenticated local connection protocol with a secure HMAC-SHA256 signature validation.
+- Excluded sensitive properties like `rpcSecret` and `rpcPort` from `DownloadItem` serialization so they are never saved to disk in plaintext.
+- Mitigated SSRF (Server-Side Request Forgery) by strictly validating metadata fetch requests against private IP addresses and loopback ranges.
+- Prevented potential path traversal vulnerabilities by validating destination file URLs during duplicate resolution.
+- Sanitized custom HTTP headers to prevent CR/LF injection vectors.
+- Re-architected `aria2c` port-finding with POSIX sockets to eliminate a known race-condition window.
+- Applied rate-limiting and text length bounds to the custom `firelink://` scheme to mitigate DoS and injection attempts.
+
+### Fixes
+- Fixed a metadata extraction timeout when downloading from YouTube by preventing child processes from holding process pipes open.
+- Resolved an issue to correctly assign filenames for auto-captured downloads.
+- Restored the UUID fallback for token generation to prevent silent failures if secure random byte generation fails.
+- Hardened local API security by immediately rejecting requests if the expected pairing token is completely empty.
+- Implemented a thread-safe cleanup mechanism for temporary directories to resolve a concurrency race condition during engine cancellation.
+
+## [0.7.0] - 2026-06-11
+
+### New Features & Improvements
+- Complete UI modernization for the context menu, toolbar, download list, and sidebar to adhere strictly to Apple's Human Interface Guidelines (HIG).
+- Overhaul of the Settings panes including Site Logins, Engine, About, Locations, and Downloads for a unified, cleaner look.
+- Introduce an "Ask where to save" global configuration option for manual location picking per download.
+- Add "Stop Time" option to the Scheduler and unit picker for the global Speed Limiter.
+- Enhance the Integration pane with a visible step counter and an up-to-date status icon.
+- Optimize `yt-dlp` execution for noticeably faster media extraction speeds.
+- Defer Keychain access prompts and track executable modification dates for a more secure "priming" mechanism.
+
+### Fixes
+- Fix issues regarding proxy environment propagation into media download processes.
+- Resolve multiple critical bugs related to configuration storage and download stability.
+- Address multiple underlying issues identified during comprehensive code reviews to improve overall resilience.
+
+## [0.6.6] - 2026-06-10
+
+### New Features
+- Add cascading media format pickers with inline loading states during metadata extraction.
+- Redesign the Integration settings pane for a more modern experience.
+- Overhaul the built-in update checker UI to integrate seamlessly into the settings.
+
+### Improvements
+- Implement keychain permission priming to defer secure access until explicitly granted, preventing unexpected macOS prompts.
+- Optimize core UI components to significantly improve rendering performance and overall app stability.
+
+### Fixes
+- Fix layout and dynamic sizing bugs in the Add Downloads window.
+- Fix formatting inconsistencies in media options selection.
+- Fix toast notification rendering glitches.

+## Why Firelink
 
----
+Firelink is built for people who want a real desktop download manager again: fast segmented transfers, browser capture, media extraction, scheduling, recovery, and clear control over where files land. Version 1.0.0 completes the move from the earlier macOS-only Swift app to a modern Rust/Tauri application with a React and TypeScript interface.
 
-## ✨ Features
+The app keeps the heavy work native. Downloads are coordinated by a Rust backend, accelerated with aria2, enriched with yt-dlp and FFmpeg for media workflows, and persisted locally with SQLite so queues survive restarts and app updates.
 
-- ⚡ **Multi-Segmented Engine:** Ultra-fast parallel downloading powered by `aria2c`.
-- 🪄 **Media Downloader:** Instantly extract high-quality audio and video formats (4K, 1080p, MP3) from sites like YouTube and Twitter, backed by bundled `yt-dlp` and `ffmpeg` engines.
-- 🎨 **Premium Native UI:** Responsive, frosted-glass SwiftUI design tailor-made for Apple Silicon.
-- 🌐 **Seamless Integration:** Send links directly from your browser with the Firelink Companion extension.
-- 🎯 **Visual Chunk Map:** Monitor active segment connections and download progress in real time.
-- 🗂️ **Smart Organization:** Auto-categorizes files into `Musics`, `Movies`, `Compressed`, and more.
-- 🛡️ **Reliable & Secure:** Deep Keychain integration for authenticated downloads, zero-configuration setup, and automatic recovery.
-- 🔄 **Native Updater:** Built-in seamless GitHub release checking for lightweight and transparent app updates without third-party frameworks.
+## Features
 
----
+- **Fast segmented downloads** powered by aria2 with configurable connections, retries, and speed limits.
+- **Media extraction** with yt-dlp, FFmpeg, and Deno for video/audio links and richer format selection.
+- **A real Add window** for manual, extension-captured, and media downloads, including metadata, duplicate handling, and save-location choices before downloads start.
+- **Persistent queue management** with safe concurrency limits, pause/resume, retry, redownload, sorting, multi-select, and bulk controls.
+- **Download scheduling** with start/stop windows, speed-limiter tools, and optional post-queue actions.
+- **Smart organization** through categories, default folders, per-download overrides, and open/reveal/trash actions.
+- **Private browser handoff** through authenticated local pairing with replay protection and desktop-server proof checks.
+- **Native desktop integration** including tray controls, notifications, completion sounds, sleep prevention, and OS keychain support where available.
+- **Diagnostics built in** with engine health checks, structured logs, and packaged-engine verification.
 
-## 🧩 Browser Integration
+## Installation
 
-We are live! Send downloads directly from your browser to the Firelink app with zero friction.
+Download the latest desktop build from [GitHub Releases](https://github.com/nimbold/Firelink/releases).
 
-<a href="https://addons.mozilla.org/en-US/firefox/addon/firelink-companion/"><img src="https://img.shields.io/badge/Install%20on%20Firefox-FF7139?logo=firefox-browser&logoColor=white&style=for-the-badge" alt="Install on Firefox" /></a>
+| Platform | Package | Notes |
+| --- | --- | --- |
+| **macOS Apple silicon** | `.dmg` | Unsigned and not notarized. Open through Finder or approve once in **System Settings -> Privacy & Security**. |
+| **Windows x64** | NSIS `.exe` installer | Unsigned. Windows SmartScreen may warn until code signing is added. |
+| **Linux x64** | `.AppImage` | Make executable before launching if your desktop environment does not do that automatically. |
 
-*(Check out the [Firelink-Extension source code](https://github.com/nimbold/Firelink-Extension) to contribute or learn more.)*
+Production bundles include the required media engines for the target platform. Users do not need to install aria2, yt-dlp, FFmpeg, Deno, Python, Homebrew, or a package manager for normal app usage.
 
----
+## Browser Extension
 
-## 🛠️ Quick Start
+<div align="center">
+  <a href="https://addons.mozilla.org/en-US/firefox/addon/firelink-companion/"><img src="https://img.shields.io/badge/Install%20Firelink%20Companion-Firefox-FF7139?style=for-the-badge&logo=firefox-browser&logoColor=white" alt="Install Firelink Companion on Firefox" /></a>
+</div>
 
-**OS Support:** macOS 14.0 or newer (Apple Silicon natively).
+Firelink Companion connects your browser to the desktop app so links and browser downloads can open in Firelink instead of disappearing into the browser's default download shelf.
 
-Run the application directly:
-```bash
-swift run Firelink
+What it adds:
+
+- **Automatic capture** for normal browser downloads, while still routing every captured link through Firelink's Add window.
+- **Context-menu actions** for "Download with Firelink" and selected links.
+- **Signed local requests** using the pairing token from **Settings -> Integrations**.
+- **Server identity checks** so the extension only trusts the real local Firelink app.
+- **Offline-safe behavior** that resumes browser downloads when Firelink is closed or rejects a handoff.
+- **Protocol-aware compatibility** so older desktop builds are rejected before automatic capture can cancel a browser download.
+
+Install the extension, open Firelink, then pair it from **Settings -> Integrations**. The Firefox add-on is maintained in the [Firelink-Extension](https://github.com/nimbold/Firelink-Extension) repository and is also vendored here as the `Extensions/Firefox` submodule.
+
+## Platforms
+
+| Target | Status |
+| --- | --- |
+| **macOS arm64** | Supported. Automated native build, engine validation, packaged launch smoke test, and unsigned DMG packaging. |
+| **Windows x64** | Supported. Native GitHub Actions build, engine validation, silent installer smoke test, and NSIS packaging. |
+| **Linux x64** | Supported. Native GitHub Actions build, engine validation, AppImage repackaging, and xvfb launch smoke test. |
+

+# Firelink Release Process
+
+Targets:
+
+- macOS arm64 DMG
+- Windows x64 NSIS installer
+- Linux x64 AppImage
+
+## Distribution policy
+
+Firelink does not use an Apple Developer account. macOS releases are unsigned and not notarized. Users must explicitly approve the downloaded app through Finder or macOS Privacy & Security. Release copy must never describe these builds as signed, notarized, or Gatekeeper-approved.
+
+Windows releases are currently unsigned. SmartScreen may warn until code signing is added.
+
+## Engine supply chain
+
+Firelink never falls back to system-installed media tools.
+
+- `engines.lock.json` pins current committed macOS payload hashes.
+- `engine-sources.lock.json` pins Windows/Linux source archives and checksums.
+- `scripts/provision-engines.js` downloads and verifies target archives.
+- `scripts/stage-engines.js` creates one target-specific bundle payload.
+- `scripts/verify-binaries.js` runs architecture, packaging, version, and RPC checks.
+
+yt-dlp must remain its official PyInstaller **onedir** distribution: launcher plus adjacent `_internal` runtime. Onefile builds are rejected because repeated extraction caused roughly 17-second startup latency.
+
+## Version update
+
+Keep versions aligned:
+
+- `package.json`
+- `src-tauri/Cargo.toml`
+- `src-tauri/tauri.conf.json`
+
+## Local macOS build
+
+```bash
+npm ci
+node scripts/stage-engines.js --target aarch64-apple-darwin
+node scripts/verify-binaries.js --staged --target aarch64-apple-darwin
+npm test -- --run
+npm run build
+cd src-tauri && cargo test --all-targets
+cd ..
+npm run tauri build -- --target aarch64-apple-darwin --bundles dmg
+```
+
+Verify packaged resources, then launch outside repository working directory:
+
+```bash
+APP="src-tauri/target/aarch64-apple-darwin/release/bundle/macos/Firelink.app"
+node scripts/verify-binaries.js --search-root "$APP" --target aarch64-apple-darwin
+node scripts/smoke-packaged-app.js --executable "$APP/Contents/MacOS/firelink"
+```
+
+GitHub release publication is intentionally manual. Tag pushes build and upload
+artifacts, but the `publish` job only runs from a `workflow_dispatch` on a `v*`
+tag when both release-certification inputs are checked after Windows, Linux,
+and macOS clean-machine QA.
+
+## Automated release builds
+
+Push a version tag to build and verify native artifacts:
+
+```bash
+git tag v<version>
+git push origin v<version>
+```
+
+GitHub Actions builds all targets on native runners, verifies engines inside
+final package contents, performs packaged launch smoke where supported, and
+uploads artifacts. Publish the GitHub Release with a manual `workflow_dispatch`
+run on the same tag after clean-machine QA is complete.
+
+No target may silently skip missing engines, failed extraction, checksum mismatch, or missing package output.

+- Project: <https://aria2.github.io/>
+- Source: <https://github.com/aria2/aria2>
+- License: GNU General Public License version 2 or later
+
+Corresponding source for the distributed version is available from the source link and release tag listed in `engines.lock.json`. Firelink release notes must retain that source reference.
+
+Linux x64 uses a checksum-pinned musl static build produced from upstream aria2 by <https://github.com/abcfy2/aria2-static-build>. Builder source and upstream tag are recorded in `engine-sources.lock.json`.
+
+## FFmpeg

+- Project and source: <https://ffmpeg.org/>
+- License information: <https://ffmpeg.org/legal.html>
+
+Current macOS binary reports `--enable-gpl --enable-version3`; distribution therefore follows GNU GPL version 3 requirements. Exact build identity is recorded in `engines.lock.json`.

+Engine payloads may contain OpenSSL, SQLite, c-ares, libssh2, gettext/libintl, zstd, and other runtime libraries. Their copyright and license notices remain part of their source distributions and embedded package metadata.
+
+Release engineering must review each newly added target payload before adding its hashes to `engines.lock.json`. Missing provenance or license data blocks release.
