+# SYNOPSIS
+#   __fish_config_sync_logging
+#
+# DESCRIPTION
+#   Synchronises C5 logging state: creates or removes the Kitty sentinel
+#   file ($XDG_CONFIG_HOME/fish/.logging_disabled) and generates or removes
+#   the paru/yay AUR-helper log wrappers based on the combined value of
+#   __fish_config_opinionated (master) and __fish_config_op_logging (C5).
+#   Called by --on-variable event handlers whenever either variable changes.
+#   Safe to call at any time; wrapper removal only affects files bearing
+#   the generated version-marker comment.
+#
+# RETURNS
+#   0  Always
+#
+# EXAMPLE
+#   __fish_config_sync_logging
