把 M61 的「OKLCh 近似 CAM16 + gamut 硬裁」换成官方的 HCT 算法，与 material-color-utilities（Apache-2.0）逐角色对上：baseline 49 角色 × light/dark、8 个种子 × 12 个强调族角色 × 2 模式，**实测每通道误差 0** （判据写入测试：≤1）。 实现（逐函数对照官方 Java 重写为 Rust，f64 内部精度）： - color/cam16.rs + viewing_conditions.rs：CAM16 色相/彩度（D65、200 lux、 背景 L* 50），默认观察条件的中间量与 Java 实测逐位对齐 - color/hct_solver.rs + critical_planes.rs：官方 gamut 映射（Newton 迭代 + 色调平面上的色相二分，255 项关键平面表原样搬运），只压彩度不硬裁 - color/hct.rs：HCT 坐标（hue/chroma/tone），公开给工具与测试 - color/space.rs：官方 ColorUtils 的 sRGB↔线性↔XYZ↔L* 换算（矩阵、阈值、 取整口径一致） - color/palettes.rs：Tonal Spot 官方彩度常数 36/16/24/6/8，error 25°/84 - color/scheme.rs：tone 表换 ColorSpec2021（on-*container 10→30、 background 99/10→98/6） 两个旧缺陷关门： - primary-container 与 secondary-container 不再撞色（彩度 36 vs 16， tone 90 装得下，无需「共享基准压彩度」补丁）；reference_chroma / tone_scaled 随之删除 - 强调色色相不再被 gamut 硬裁（只压彩度，实测偏移 <1°） 对齐证据：tests/official_baseline.rs（98 项 + 12 个 HCT 探针）、 tests/official_accent.rs（192 项）。期望值是把官方 Java 实现本机编译运行 的输出抄本，并用 Flutter 的 ColorScheme.fromSeed 用例交叉验证 （#00FF00 → #406836、#000000 → #8C4A60、#FFFFFF → #006874 一致）。 诚实口径：只做 Tonal Spot 变体 + contrastLevel 0；对比度三档、其他变体、 壁纸多色取色、非默认观察条件都在模块文档的 gap 表里登记。 注：token_pins 的 tone 值变化来自官方算法（ColorSpec2021），不是为过测试而改。 NOTICE 增「Google Material Color Utilities」归属（Apache-2.0 要求， 含逐文件映射与对齐方法）。
Unlucky Launcher (ULL)
English · 简体中文
Official project home: https://github.com/AskaEth/Unlucky-Launcher
Unlucky Launcher (ULL) is a free, open-source Minecraft: Java Edition launcher written in Rust (Apache-2.0, non-commercial), with a Slint + Metro UI. It embeds an AI agent client (chat / configuration / crash diagnosis) and integrates with the broader agent tooling ecosystem via MCP. Minimum baseline: Windows 10.
- Runtime: a single native Rust binary — no JVM, no WebView, no external runtime
- UI: Slint (Royalty-Free 2.0; GL preferred, CPU software-rendering fallback so older machines without a usable GPU still get the full UI)
- License: Apache-2.0 © AskaEth (YeiJ)
Compliance statement
Authentication uses only official Microsoft/Mojang endpoints — Microsoft OAuth 2.0 device code flow, Xbox Live, XSTS, and api.minecraftservices.com — so players sign in with their own Microsoft account and launch the game they already own. Account tokens are stored only on the user's local machine and are never sent to any server operated by the project. ULL does not distribute, mirror, proxy or modify any Minecraft game files. Online play always requires a Microsoft account with valid entitlements. Local offline profiles never contact Microsoft or Mojang services and cannot join online-mode servers. Not affiliated with Mojang or Microsoft.
Status
The core engine is complete (workspace: 983+ tests passing):
- Microsoft sign-in: OAuth 2.0 device code flow → Xbox Live → XSTS → Minecraft Services, with entitlement verification
- Account credentials are stored only on the local machine — never uploaded, and inaccessible to the AI features
- Mod loaders: Forge / NeoForge / Fabric / Quilt, verified on real machines
- Java management: Temurin / Oracle / Microsoft / Zulu with a regional fallback chain
- Multi-source download engine; YAML rule-based crash diagnosis
- Usable as an MCP server for external agent tooling (
ull agent serve) - Local offline profiles: for local / isolated-network testing only; they perform no Microsoft authentication and cannot join servers with online-mode enabled
CLI (ull) is fully usable: install / launch / accounts / java / diagnose / agent.
GUI in development: crates/app is currently a Slint + Metro skeleton; the theme system and
the full interface ship with subsequent versions — use the CLI until then.

The eight modules of crates/core:
| Module | Responsibility |

download |
multi-source health scoring, mirrors, chunked downloads, hash-while-downloading |
game |
version / instance repository, snapshots and inheritance resolution |
launch |
10-stage launch pipeline, processes, JSONL event stream |
auth |
Microsoft sign-in / local offline profiles |
addon |
mod loader installation, modpacks, CurseForge / Modrinth |
diagnose |
five signal collectors, YAML rule engine, hs_err parsing |
platform |
OS abstraction: paths, processes, file locks, capability probing, runtime OS detection |
Building
Prerequisites:
- Rust stable (
rust-toolchain.tomlselects the toolchain automatically; componentsrustfmt/clippy) - Windows: MSVC toolchain (used by CI) or MinGW-w64 (
x86_64-pc-windows-gnu) - Linux:
libxkbcommon-dev libfontconfig1-dev libgl1-mesa-dev libegl1-mesa-dev libwayland-dev libxcb1-dev(Slint winit backend + femtovg build dependencies)
cargo fmt --all --check # formatting
cargo clippy --workspace --all-targets -- -D warnings # lints (zero-warning gate)
cargo test --workspace # tests
cargo build --release # artifact: target/release/unlucky-launcher[.exe]
Software-rendering switch (machines without a usable GPU / with broken drivers):
unlucky-launcher --software-renderer (equivalent to SLINT_BACKEND=winit-software).
Dependency license check (optional locally, required in CI):
cargo deny check licenses bans sources.
CI gates
| Workflow | Content |
|---|---|
.github/workflows/ci.yml |
fmt + clippy + test + build, Windows / Linux matrix |
.github/workflows/guards.yml |
zero-UI guard for core, 400-line-per-file guard, cargo-deny license guard |
Platform baseline
Minimum baseline: Windows 10. Windows 8.1 / 8 / 7 are not supported:
- Windows 10/11 builds use the standard toolchain (MSVC / GNU) — no custom target specs, no
-Zbuild-std, no import-table allowlists - Other platforms: macOS 12+ first class; Linux x64 with X11 preferred, Wayland as the long-term direction; Android Termux experimental, not committed
- UI fallback: Slint software rendering (fully usable on machines without a GPU or with broken drivers)
- Platform independence is expressed through separate test matrices, not separate artifact pipelines; capability differences use feature gates with runtime probing

Thanks to HMCL and PCL2 (both GPL-3.0) — these two launchers have accompanied the vast majority of Minecraft players for many years. ULL learned a great deal about design and implementation from them, and this project is dedicated to those two pioneers.
