Validate deliverable file formats by running the artifact validator on a directory to enforce per-file checks, detecting misnamed files or HTML masquerading as other types. It generates a per-file pass/fail authenticity report suitable for QA gates.

Detect HTML masquerading as PPTX or XLSX through integrity checks that verify embedded content and enforce the presence of real formats. The validator inspects each file to ensure formats like PPTX contain slides and XLSX contain formulas.

Verify PDF and DOCX deliverables by running format validation checks that confirm real embedded content, such as text within a PDF. The validator enforces per-file authenticity across common deliverable types to prevent fake outputs from shipping.

Automate format authenticity reporting by providing the deliverables directory and an optional contract to the validator. It produces a per-file pass/fail report that guarantees format integrity and is suitable for client reviews and QA gates.

The deliverable validator works with multi-file directories containing mixed formats by applying per-file verification across common deliverable types. It enforces format integrity across the entire directory before generating a comprehensive pass/fail report.

Format validation fails for misnamed files because the integrity checks detect discrepancies between file extensions and actual embedded content. The validator enforces the presence of real formats, rejecting files that do not match their claimed type.
