fix: install scripts trap unbound variable on exit (s0.18) - #59
Merged
Conversation
Move tmp variable from local scope in main() to module-scope TMP_DIR with a cleanup() function. The EXIT trap now references a variable that is always in scope, fixing the "variable sin asignar" error under set -u. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
