+"""Unit tests for the friendly rookiepy error message formatter.
+
+``_handle_rookiepy_error`` is a pure helper: it classifies a rookiepy
+``OSError``/``RuntimeError`` into one of four user-facing message shapes
+(locked DB, permission denied, decryption failure, generic) and returns
+Rich-markup text. These tests pin each classification branch.
