 | Date | Change | Summary |
 |---|---|---|
+| 2026-11-12 | minor | Tests (#6860): compare preset refusal roots after canonicalization and Windows display normalization; canonicalize the script fixture base before constructing `MAIN`. This keeps macOS `/var` → `/private/var` aliases from masking the case-sensitivity checks; no production-code change. |
 | 2026-11-06 | minor | Localisation: Hindi catalog, zero/one plurals, desktop and web font requirements; AI/MT draft, native review pending. |
 | 2026-10-31 | minor | Files opened while the app runs open in its window on Windows and Linux (#4892); `--new-instance` opts out. |
 | 2026-10-29 | minor | Linux clipboard: core Wayland protocol text fallback where arboard has neither data-control nor X11 (the Flatpak on GNOME).; its reads wait 2 s at most. |
