Validate¶

Status: Validation gates are written; representative accuracy remains unvalidated

Question¶

What does Validate receive, do, produce, and refuse to claim?

Short answer¶

Validate measures Drawing Lab results against human-reviewed truth. Software tests verify behavior. Software tests do not validate drawing accuracy.

Receives¶

Understood objects and incomplete evidence that remains visible
Append-only human review records
Evaluation metrics from representative sheets
Owner acceptance decisions

Does¶

Separates verified behavior from validated accuracy
Measures table region quality, structure quality, and cell-text quality when truth exists
Measures dimension component recall, complete-dimension recall, false candidates, attachment accuracy, and parsing accuracy when truth exists
Records cold and warm runtime separately before speed claims
Keeps review proxies such as accepted, adjusted, rejected, and manually added counts labelled as proxies

Produces¶

Validated claims only when representative human-reviewed truth supports them
Accepted product boundaries after owner decision
Explicit non-claims when evidence is incomplete

Does not claim¶

That a preferred provider choice is a production accuracy score
That local timing on one machine is a product SLA
That review-rail counts are formal precision or recall
That Detected Sheet completeness equals accuracy

Current contract gates¶

Tables require region precision and recall, false positives and misses per sheet, boundary quality, structure accuracy, and cell-text accuracy. Dimensions require component and complete-dimension recall, false candidates per sheet, feature-attachment accuracy, parsing accuracy, and controlled cold and warm runtime. Fine-tuning stays deferred until roughly 30-50 representative sheets are fully reviewed and failure families justify it.

Next stage receives¶

Reviewed evidence and truth feed product claims, later experiments, and accepted decisions.

Open Questions¶

Which first sheet corpus will open formal table and dimension validation?
