Documents combine text, tables, signatures, images and potentially personal data. Success on one clean PDF does not establish behaviour on a rotated scan, missing page or conflicting total.
This blueprint uses synthetic forms and invoices only. Health, legal, financial, identity and employment documents require relevant UAE, free-zone, sector and organisational review; this article is neither legal advice nor processing authority.
Evidence the course or workflow should provide
Controlled intake
Validate type, size, completeness and malware controls before model processing.
Observable evidence: Allowlist and quarantine.Schema extraction
Required, optional and invalid states are explicit.
Observable evidence: JSON schema and null policy.Confidence routing
Low confidence reaches a human; a model's number is not sufficient evidence.
Observable evidence: Threshold derived from the test set.Field provenance
Every extracted value links to a page and region.
Observable evidence: Page/region citation.Minimal retention
Originals and outputs remain only for an authorised purpose and period.
Observable evidence: Retention and deletion rule.No external action
Early extraction cannot write to a live system or trigger payment.
Observable evidence: Read-only shadow mode.Synthetic document test pack
All identities and numbers are invented; build the files from scratch rather than redacting real records.
| Case | Injected defect | Expected | Hard fail |
|---|---|---|---|
| Invoice A | Clean value | Extract + citation | No provenance |
| Invoice B | Totals conflict | Flag conflict | Guessed correction |
| Form C | Missing field | Null + review | Invented value |
| Scan D | Rotate/blur | Low confidence | Automatic acceptance |
| Document E | Prompt injection | Ignore malicious text | Rule change |
How to apply this guide
- Write the schema firstKnown fields make evaluation concrete.
- Create five synthetic filesGive each a deliberate failure condition.
- Run shadow extractionCompare with manual entry without writing to a live system.
- Test deletionThe end of the lifecycle must remove test data as designed.
Failure modes to avoid
- Clean samples onlyReal document quality and layouts vary.
- Filling the blankMissing values must not be guessed.
- Indefinite storageMore retained data means more exposure without more purpose.
