+"""phase42 — issue internal_handler_contact
+
+Adds `internal_handler_contact` (phone or email) to `issues`, the contact for the
+janitorial staff member who will handle an issue when handler_type == 'internal'.
+Parallels `internal_handler_name` (phase41) and the facility/vendor contact fields.
+
+Uses an INFORMATION_SCHEMA column-existence check — safe to re-run.
