CatQualia code-quality corpus — semantic smell classes with before/after fixes
39,383 rows · 25,541,792 bytes · JSON Lines, one object per line.
What this is
Real code smells paired with the fix: a smell_class that names the semantic problem (not just the syntax), the original lines, the corrected lines, the file and line it came from, and a rationale explaining why the original was wrong. Useful for code-review or repair training where the label has to say what is wrong rather than merely flagging a line.

The row count was measured with wc -l against the file staged here, not against a
source copy.
How it was produced
By the author's own generation pipeline: candidate rows are produced from seed material,
graded, and the survivors assembled. Several fields (notably grade and any
alien_or_typical judgement) are the pipeline's own assessment, not an external label.
The method is described at https://catqualia.com/forest.
Known limitations
- Synthetic and self-graded.
grade,alien_or_typicalandfailure_classcome from the generating pipeline. They are not human-annotated ground truth. - Generated at scale. Volume is not evidence of quality; a large fraction of rows may be unremarkable.
- English only.
- Provenance of individual rows varies and is recorded per row where the pipeline captured it.
- Not peer-reviewed, not independently evaluated.
