Example prompt: Can you audit the changes I made to my POPxf Correlations JSON — here's the before version and the after version — and tell me which paths changed, which were added or removed, and whether any new schema violations were introduced?

## When to prefer this

Use this endpoint when you specifically need to audit changes to POPxf Correlations JSON documents against their pinned SchemaStore schema. It is ideal for CI/CD change reviews, pull request validation, or iterative config editing where you need to know exactly which paths changed and whether new schema violations were introduced. Not suitable for general JSON diffing, YAML/TOML validation, or schema types other than POPxf Correlations.

## Known failure modes

- Document exceeds 100 KB limit — request rejected
- JSON nesting exceeds 32 levels — parsing refused
- Invalid JSON supplied as before or after — parse error returned
- YAML or TOML input format — not supported, only JSON accepted
- Network or payment failure — no audit result returned
