+Subject: [PATCH] Fix uninitialized wrapped script arrays causing shellcheck
+ failures
+
+When ARGBASH_WRAP is used, the code generator creates combined arrays
+that reference both _opt and _pos suffixed arrays for each wrapped
+script group:
+
+    _args_test_onlyopt=("${_args_test_onlyopt_opt[@]}" "${_args_test_onlyopt_pos[@]}")
+
+However, if a wrapped script only had positional arguments OR only
+optional arguments, one of these arrays would never be initialized,
+causing shellcheck SC2154 warnings ('variable referenced but not
+assigned') and test failures.
+
+This commit fixes the issue by:
+
+1. Initializing both _opt and _pos arrays as empty arrays for ALL
+   wrapped script groups during the defaults initialization phase.
+   This is done in both _MAKE_DEFAULTS_POSITIONAL and
+   _MAKE_DEFAULTS_OPTIONAL to ensure coverage regardless of which
+   argument types the script has.
+
+2. Adding a shellcheck disable directive (SC2154) in the generated
+   assign_positional_args function where wrapped positional arrays
+   reference variables like $_arg_pos_arg. These variables ARE
+   assigned via eval, but shellcheck cannot trace dynamic assignments:
+
+       eval "$_positional_name=\${1}"
+
+   The disable directive prevents false positive warnings while
+   keeping shellcheck validation for the rest of the generated code.
+
+Fixes shellcheck errors in scripts using ARGBASH_WRAP such as:
+- test-wrapping-second_level.sh
+- test-wrapping-excl.sh
