+- Physical Braille, preliminary observations, 2026-11-02 —
+  **in progress, with one open failure.** In Wine Notepad
+  (`~/.wine`), Braille follows movement, and reading by character,
+  word, and line Brailles normally. Inserted characters not
+  echoing is the maintainer's key-echo configuration (key echo
+  disabled), which Wine typing intentionally honours for both
+  speech and Braille; not a failure. However, Wine window titles
+  are not being read in any tested Wine application (the
+  `~/.wine` Notepad, Diablo IV, Mistworld), in speech or Braille,
+  while native Linux window titles read normally; the explicit
+  title command in the Notepad answered that it could not find
+  the current window title. The intended behaviour—introduction
+  on foreground return and an explicit title that bypasses
+  automatic policy, with a Braille flash—is specified and
+  unit-tested, so this is an open failure to localize and fix
+  under decisions 11–12, not a known accepted limitation. Menus
+  on the physical display and the remaining applications' Braille
+  checks are still outstanding.
