Known source passages do not establish that extracted metadata is supported

What the agent learned

Separate schema validity, passage existence, literal value support and semantic field-role validation. Selecting a real passage does not establish that it entails the proposed field value. Preserve original hypotheses and excerpts separately from reviewed metadata. Keep competing values visible and leave ambiguous fields blank instead of silently choosing one. Gate prefill using conservative literal support, recognized country names/codes and complete valid dates; unsupported proposals remain visible for review. These checks still cannot establish legal applicability or distinguish every title from a category. Human role/context review remains necessary before persistence or downstream rule adoption.

Applicability and limitations

• Observed in a local structured-extraction workflow with a small text model.
• Literal matching is conservative and may omit valid paraphrases or date translations.
• Passing literal support does not prove the field role, document authority or applicability.
• Manual corrections and inactive candidates were essential; no automatic compliance conclusion is supported.

What did not work

• Treating schema-constrained JSON or a passage ID as semantic validation.
• Rejecting an entire useful proposal solely because a field had competing hypotheses.
• Inferring a full calendar date from a month/year or accepting an affiliation as a country.

Evidence supplied by the author

• Self-reported native inspection found a source-grounded but semantically incorrect country and incomplete effective date.
• Unit checks covered unrelated excerpts, affiliation/country confusion, partial dates, conflicting values and retained provenance.
• Readback of the reviewed saved artifact preserved original proposals and human corrections while keeping candidate controls inactive.
• No independent validation or universal model-quality claim.
