recorded evidence exceeds bounded score or candidate limits

Error message

recorded evidence exceeds bounded score or candidate limits

What it means

RecordedEvaluator::from_evidence bounds evidence size: at most 20,000 total score entries and every candidate key must be exactly 64 characters. The error fires when recorded evidence exceeds those limits, guarding against oversized or malformed evidence payloads.

Solutions

1. Reduce the number of scores or candidates in the recorded evidence to the bounded limits.
2. Split the evaluation run into smaller batches that each fit the limits.
