…e's floor
推迟 `provides = ["mcpp:compiler-runtime=…"]` 的注释把判据写成了
「本包的 floor 移到 2026.8.24.2」。判据不是这个 —— 读这份文件的人
手上有什么,由**索引服务哪个版本**决定,和本包声明的 floor 无关。
2026-08-24 实测,依赖各声明一个键,构建工具取索引 `latest` 指向的版本:
requires = ["mcpp:compiler=llvm"] 2026.8.24.1 exit 0,静默忽略
provides = ["mcpp:compiler-runtime=…"] 2026.8.24.1 exit 2,整份拒绝
⭐ 于是两个键的答案是分开的:`requires` 今天就能发,层声明不能。
而 24.2 引入的那份宽容对现实中的任何用户都还不存在 —— **24.2 从未进索引**,
索引的 latest 停在 24.1。「新版本支持了」和「用户拿得到」是两件事。
开门条件改写为:索引的 `latest` 到达 2026.8.24.2 或以上。

mcpp:compiler-runtime声明的注释把判据写成了本包的 floor。判据应当是索引服务哪个版本——那才是读这份文件的人手上有的东西。2026-08-24 实测(依赖各声明一个键,构建工具取索引
latest指向的版本):requires = ["mcpp:compiler=llvm"]provides = ["mcpp:compiler-runtime=…"]两个键的答案是分开的。另外:24.2 引入的宽容对任何真实用户都还不存在,因为 24.2 从未进索引。开门条件改为索引 latest ≥ 2026.8.24.2。
