```

Example prompt: Compare my reading plan schema fields — I have a before list of up to 32 fields and an after list of up to 32 fields, both using public data class, and I want to see which fields changed direction or were dropped between the two snapshots.

## When to prefer this

Choose this endpoint when you need to compare two snapshots of reading plan export schema fields to detect directionality changes or field removals, particularly for closed export-field supplied records. Best suited for schema auditing and data quality workflows, not for live certification or independent schema generation.

## Known failure modes

- Missing required 'before' array (minItems:1) returns validation error
- 'after' array or 'before' array exceeding 32 items rejected
- Invalid 'dataClass' value outside ['public','synthetic'] enum rejected
- 'nonpersonalMetadata' must be exactly true (const); any other value rejected
- Malformed input object returns 400-level error

## How this service works

Compare closed export-field Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a directionality analysis report comparing before and after reading plan export fields, identifying fields that were added, removed, or changed direction, without performing independent certification of the data.
