AMR v0.1.5

AMR (Antigravity Manager Rust) v0.1.5

Release Highlights & What's Changed

• Antigravity 2.29.1 Client Emulation: Updated upstream hub version and CL metadata (antigravity/hub/2.29.1, CL 1015941558) to match latest Antigravity desktop release (44.5.1).

• Upstream Image, STT, & TTS Protocol Fixes: Switched /v1/images/generations, /v1/audio/transcriptions, and /v1/audio/speech to non-streaming v1internal:generateContent (Accept: application/json) with automatic OAuth token refresh, aspect ratio support, PCM-to-WAV wrapping, and authentic voice mapping.

• Web Search (POST /v1/search & googleSearch Grounding): Reverse-engineered Antigravity GetWebSearchResults (requestType: "web_search", googleSearch tool, groundingMetadata sources) and exposed POST /v1/search, the web-search catalog model, and OpenAI web_search tool mapping in /v1/chat/completions.

• Personalized UI Test Modals & Modality Badges: Added distinct model badges (Image Gen, Audio STT, Audio TTS, Web Search) and tailored interactive Test Dialogs for image preview/saving, STT audio file browsing/transcription, TTS voice synthesis/playback, and manual web search with sources.

• Metadata-Driven Version Placeholders & Packaging: Synchronized Cargo.toml (0.1.5), Slint UI version, metainfo XML/desktop stamping in build_appimage.sh / build_deb.sh / build_rpm.sh, README.md placeholders, and dynamic changelog extraction in .github/workflows/release.yml.

• v0.1.4:

• Window & Tray Integration: Fixed window minimize-to-tray lifecycle on Linux/Windows and preserved dynamic tray context actions.

• Prompt Caching & Telemetry: Integrated real prompt caching ratios, request latency counters, and token tracking.

• UI / Model Explorer: Added model ID copy chip, grey thinking badges, and sanitized upstream headers.

• Windows Dependencies: Added Win32_System_ProcessStatus and Win32_System_Threading features to windows-sys.

• v0.1.3:

• Protocol Alignment: Eliminated problematic upstream endpoints causing synthetic 429 errors and aligned request schemas to native Pa API parameters.

• v0.1.2:

• Windows Subsystem: Configured #![windows_subsystem = "windows"] to suppress unwanted background console windows.

• OAuth & State: Fixed URL escaping and token keeper persistence across application reboots.

• UI Quota: Fixed rendering when quota reaches 0%.

• v0.1.1:

• Packaging: Streamlined AppImage, DEB, RPM, and EXE build scripts with cross-distro compatibility.

• v0.1.0:

• Multi-Architecture CI: Introduced standalone 64-bit ARM (aarch64 Linux & arm64 Windows) build matrix.

• v0.0.4:

• Antifraud & Identity: Implemented randomized jitter refresh (±15%), hardware fingerprint generators, and comprehensive trilingual i18n (EN, RU, ZH).

• v0.0.3:

• Security & Storage: Added persistent SQLite token cache, device isolation, and per-account proxy support.

• v0.0.2:

• Models: Enriched /v1/models broadcast with reasoning capabilities and reasoning clone toggle.

• v0.0.1:

• Core: Initial release of pure Rust AI API proxy and protocol emulator under MIT License.

Core Philosophy & Design Principles

1. Zero Bloat & Zero Telemetry:

• No analytics, tracking, ads, or phone-home requests are allowed under any circumstances.
• Do NOT introduce WebViews, Chromium, Electron, or Node.js dependencies.

2. License Compliance:

• The project is licensed under MIT License.
• Preserves standard permissive open-source usage with attribution retained.

3. Lock-Free Concurrency:

• Never hold standard blocking locks across async .await boundaries.
• Use tokio::sync, atomic counters (AtomicU64, AtomicBool), or parking_lot::RwLock for synchronous operations only.

4. Thinking Stream Resilience:

• All SSE streams must maintain heartbeat/ping frames (: ping\n\n) when reasoning models (Claude 3.7, o1, o3, Gemini 2.5) take extended time before first token arrival.
• Always map and recover reasoning tokens (reasoning_content in OpenAI chunks; thinking blocks in Claude).

5. Dual-Mode Reasoning:

• Both suffix-based clones ((low), (medium), (high), (no-thinking)) and native protocol parameters (reasoning_effort, thinking) are parsed via the declarative REASONING_SUFFIXES table in src/proxy/router.rs.

6. Strict Internationalization (i18n):

• Every single user-visible string in the UI, system tray, notifications, test runner, and status indicators must be declared in i18n/{en,ru,zh}.json and mirrored in src/i18n.rs (TranslationBundle) and ui/app.slint (I18nData).
• Hardcoded English UI strings are prohibited.

7. Cleanliness & Linter Standard:

• Zero clippy warnings (cargo clippy --message-format=short).
• All 15+ router, mapper, balancer, and model tests must pass at all times (cargo test).

Release Packaging & Artifacts

The release workflow (.github/workflows/release.yml) builds standalone release packages in 4 architecture pairs (x86_64 & arm64):

• Linux AppImage: AMR-*-x86_64.AppImage & AMR-*-aarch64.AppImage
