Comparing wrong source order
Place baseline in original and updated copy in modified panel.
Line-ending differences look noisy
Normalize line endings before comparison when possible.

Review both whitespace and token changes explicitly.
Large pasted blobs are hard to scan
Split comparison into focused sections for critical review.
Assuming visual diff equals full validation
Pair diff review with tests for runtime-impacting content.
Text Diff Checker should be treated as a repeatable validation step before merge, release, and handoff.
Can I compare long documents?
Yes, but splitting by section improves review quality.
Does it detect only line changes?
It highlights text-level edits within lines as well.
Why does whitespace generate many changes?
Whitespace differences are treated as edits by the diff engine.
Should I use this for config rollbacks?
Yes, it is useful for validating exact rollback delta.
Can this replace automated tests?
No, diff review complements but does not replace tests.
