build-glibc.sh 在源码、打包名及配方多个位置依赖 x86_64/lib64。 +需要参数化，而不是只给 archs 加 aarch64。保留其 loader 默认搜索路径、 +ld.so.cache、ld.so.preload、安装前缀 relocation 与 locale/gconv 修补。 +2.44.3 是索引包版本；其上游源码版本、修订与补丁集合分别记录。 + +推荐 aarch64 布局为 `lib/ld-linux-aarch64.so.1`、`lib/*.so*`、 +`include/`，runtime export 为 `abi = linux-aarch64-glibc`， +`loader = lib/ld-linux-aarch64.so.1`，明确 `libdirs = {lib}`。 +这是本方案指定的布局，构建与包验收必须使其成立，不能当作上游归档布局。 +x86_64 的 lib64 布局继续有效。loader 文件名、核心库清单、配置/检查中的 +libdir、辅助程序启动路径均来自同一架构描述。 + +### 4.4 架构路由与兼容性 + +每个配方必须同时核对：archs、版本可用集合、每架构 URL/sha256、 +依赖坐标、解包目录、runtime exports、sysroot 配置与测试。单独扩大 +archs 会让旧版本也被误报可安装；20.1.7/22.1.8 的 aarch64 缺席应继续 +是具名不可用，而不是尝试下载不存在的旧 ARM64 资产。 + +优先复用现有 libxpkg 的实际架构注入和资源解析契约。在加载 package +表的时刻是否能可靠读取目标架构，需要在发布版 xlings、mcpp vendored +xlings 两个入口上实测。历史文档曾记录 os.arch stub；本地较新 +libxpkg 已有 `__xpkg_arch__` 注入，这只提供检查方向，不证明已发布 +客户端具有同样能力。涉及 arch 选择的 loader/ABI metadata 不能延迟到 +install 回调后才修改，因为 resolver 可能已读取 exports。 + +若现有客户端不足，优先使用现有按架构资源契约或明确架构包坐标， +保持公开 `llvm@23.1.3` 在解析层可达；需要客户端能力时声明最小版本。 +此处设为兼容性门，未验证前不假定两仓库改动足够，也不先开新的协议。 + +### 4.5 发布内容不可变 + +新增 ARM64 资产可以挂既有 23.1.3 release；不能重写已发布的 x86_64 +同名文件。新资源有三方相同 sha256：carve、GLOBAL 重下载、CN 重下载。 +每架构每格式各自钉摘要，不共用 x86 哈希。错误资产需要具名 revision +与新文件名；不依赖 GitCode 覆盖同名文件。 + +## 5. mcpp：宿主默认、目标能力与构建链 + +### 5.1 只为 aarch64 增加默认分支 + +新增 `kFirstRunLinuxAarch64 = llvm@23.1.3`，在 +`pins::host_default_toolchain` 中显式区分 x86_64、aarch64、其他 Linux。 +保留 `kFirstRunLinuxOther`，避免 riscv64 等没有载荷的宿主被改成 LLVM。 +首次安装、self env、建议安装消息与默认值文档读取同一钉点。 + +新的默认产生 aarch64-linux-gnu，不能从此前 musl 的持久 target 或 GCC +解析惯例继承而出现 `LLVM 默认 + musl target` 的隐式组合。冷 home 的 +双轴断言是验收门；已有记录不强迁，显式用户选择仍保持优先级。 + +### 5.2 将 native GNU 行从 planned 转为实测支持 + +在原生 ARM64 Linux 完成编译、链接和运行门后，把 +`aarch64-linux-gnu` 提升为 verified；推荐该行 pin 为 `llvm@23.1.3`， +其语义是原生 glibc 工具链约定，不是禁止其他可服务编译器的能力锁。 +sysroot 来源按现有 runtime binding 机制接入受管 glibc 与 UAPI 头。 +若增加 sysroot 坐标，必须确认该字段确实被现有 hosted GNU 路径消费， +不能只在表上填值就宣称引擎已支持。 + +验证 `host_can_serve`、planned gate、toolchain list、why、matrix 扫描 +和实际 build 一致。原生 host 能用的 GNU 行不意味着 x86_64 Linux、 +macOS、Windows 已有 aarch64 glibc cross sysroot；这些组合仍给明确 +的 refusal 或 graph-supplied 支持，不升级为 payload-served。 + +### 5.3 按宿主与版本公布可用性 + +移除 `available_toolchain_indexes` 对 Linux aarch64 的 LLVM 全族隐藏， +但仍隐藏没有载荷的其他架构。允许列出 LLVM 族后，旧发行版列表必须 +按实际平台资源过滤，不把 20.1.7/22.1.8 也当作 ARM64 可装版本。 +替换 `check_aarch64_llvm_deferral.sh` 的历史否定门为正向安装门： +当前 line 的资源存在、架构正确、可安装且可启动。其他 deferred 组合 +保留各自的理由，不删掉所有保护分支。 + +### 5.4 mcpp 自举与宿主工具跟随新默认 + +根 mcpp.toml 的 `[toolchain] default = gcc@16.1.0` 不会因 first-run +默认变化自行变成 LLVM。推荐使用已有 +`[target.aarch64-linux-gnu] toolchain = llvm@23.1.3`；当前实现会在无 +`--target` 时应用 host row，CLI 指定仍优先。不引入未经实现的 +`[toolchain.linux-aarch64]` 拼法。对 native build 实测匹配到 GNU host +row；专用 CI 另显式传入工具链与目标，记录两种入口的结果。 + +build.mcpp、path host tool、import std/std.compat 和单测均用这套宿主 +运行链验证；musl 静态发布继续走显式 aarch64-linux-musl。bootstrap +可以仍是静态发布二进制，不要求发布程序本身依赖新 glibc 才能启动。 + +### 5.5 ABI 与系统库边界 + +glibc C ABI 可用于链接 C 系统库；这不等于 libc++ 可直接消费所有 +libstdc++ C++ ABI 的预制包。继续使用现有 ABI tag 与 prebuilt 校验， +GCC → LLVM 后旧 BMI、标准库模块与链接产物必须失效。 +测试 C ABI 依赖、共享库、pack 后运行、异常跨模块与线程；不默认允许 +跨标准库传递 std::string/std::vector。 + +## 6. 把 #781 review 缺口纳入交付 + +| Review 问题 | Part 2 的具体处理 | 完成判据 | +|---|---|---| +| xcode-27 缺第

+### 14.3 跨仓库任务依赖与原生证明 + +1. xim-pkgindex 完成 ARM64 LLVM 工具、受管宿主 glibc 与配套依赖 + 的安装准入；这是编译器及宿主构建程序运行的前置条件。 +2. mcpp 的 ARM64 原生门验证 openkal-linux/musl/C++ runtime 从图 + 构建并实际运行，报告 kernel-abi、c-abi、c++-abi

项的交叉路径以 `nlohmann.json@3.12.0` 为代表库。 +现有托管线程应用增加真实 `nlohmann.json` 模块依赖，验证 JSON 的 +序列化、解析、字面量及 ordered_json 键序。模块由实际 mcpp-index +配方和经哈希核对的上游源码生成，未以测试内的模拟模块替代。 + +四宿主构建分别记录 mcpp-index 提交，并在目标运行门比较来源； +应用仍按三个目标构建且由对应系统运行。原生 ARM64 与发布后的 +CN SubOS 使用实际索引 checkout 供应同一依赖。库行为与 TLS/ +线程行为各有独立成功行，目标门要求两者均出现。 + +原生 GNU 门中的 cjson、sqlite3、fmtlib.fmt、nlohmann.json 四成员 +继续保留。其结果不扩展为四库均可在所有 openkal 目标运行；本轮
