High OCR scores can mask field mapping and structural failures that destroy table usability.
Silent field-relationship errors hide wrong entity assignments that pass basic validation checks.
Contracts and output validation catch schema changes that silent pipelines otherwise hide.
Vendor discipline on tooling and integration matters more than raw model accuracy.
Silent model updates break document pipelines without triggering alerts.
Missing table rows can pass validation while corrupting downstream analytics.
Silent field drops happen when document layout shifts break parser assumptions.
Proprietary parsing and schema lock teams into platforms faster than they realize.
