What this tool does

Strict, bounded, local processing

Semantic comparison focuses on represented mappings, sequences, and scalars. Formatting, comments, and equivalent presentation choices are intentionally outside the result.

Parsing removes presentation noise

A line diff can mark an entire block after re-indentation even when its values are unchanged. Semantic comparison parses both sources, walks their values, and reports typed changes at the smallest supported path.

Mapping member order is not reported as a value change. Sequence order remains significant because moving an item changes its position in the represented sequence.

Comments require a source-oriented review

Comments and style can matter to maintainers even when an application ignores them. Use version-control review alongside this value comparison when source presentation is part of the approval contract.
