+`credit_note.sh` formats a credit note incorrectly:
+
+- It prints a debit label instead of a credit label.
+- It preserves the sign instead of always showing the credited amount as positive.
+
+Use the smallest correct fix, then run this exact verification command from the `repo/` directory:
+
+`sh tests/test_credit_note.sh`
+
+If you use `apply_patch`, the patch paths must still be relative to the sandbox workspace root. That means the file paths should be `repo/credit_note.sh` and `repo/tests/test_credit_note.sh`.
+
+Do not change the test expectations.
