To fix a credit-note formatting bug, inspect repo/task.md, review credit_note.sh and tests/test_credit_note.sh, apply the smallest correct patch preserving the credit label and positive amount, then run sh tests/test_credit_note.sh to verify.

A credit-note test fails when the output label or amount formatting deviates from expected values. Inspecting the test script and applying a minimal patch to preserve the credit label and positive amount resolves the formatting mismatch.

The best way to apply a minimal patch is to inspect the targeted test file, identify the formatting discrepancy, modify the script to preserve the required label and positive amount, and execute sh tests/test_credit_note.sh from the repo directory to verify.

No external dependencies are required to run the credit-note test verification. The process relies on standard bash scripting, executing the sh tests/test_credit_note.sh command directly from the repository directory to validate the minimal patch.

You can use this minimal patch approach to debug shell script formatting issues by inspecting the task requirements, applying the smallest correct code change to preserve output formatting, and running the targeted test command to verify the fix.
