[1.4.2] — 2026-08-28

🔴 The change / 這一版做的事

One defect, found by releasing v1.4.1: the file index was sorted by platform, not by name.
🔴 索引的排序取決於作業系統，⛔ 而不是檔名。

Fixed / 修正

• 🔴 tool_my_index.py sorted Path objects. ⚠️ WindowsPath comparison casefolds
  first; PosixPath does not — so PROJECT.md sorts before corpus/ on Linux and after it
  on Windows.
  ⛔ The index shipped with v1.4.1 was generated on Linux, so sensor_my_index.py reported
  MY_INDEX_STALE on the first run on a Windows machine.
  ⚠️ What it reported was ⛔ not "the index is stale" but "your operating system is not the
  one that generated it" — and it had already forced a manual workaround mid-release.
  🔴 A criterion that fires on a correct state teaches people to ignore it (R-19).
  The sort key is now the relative posix string. ⛔ Never the Path object.

Self-tests / 自測

78 → 79. ⚠️ The new sample is honest about its reach: it only lights up on a
case-insensitive filesystem (Windows, macOS). ⛔ On Linux the old and new code agree, so it
cannot fire there — it is kept because the release procedure runs the self-test on Windows.

⛔ This release does not claim / 本版不宣稱

• ⛔ That every generated artefact is now reproducible across platforms. ⚠️ Only this one
  was examined. The general shape — "sorted() on a type whose ordering is platform-dependent" —
  ⛔ has not been swept for.
