# Description of Changes This PR replaces the legacy, fragile PDF/A validation logic (which relied on manual regex parsing and PDFBox Preflight) with the robust **VeraPDF** integration. Additionally, it introduces a new check for **SEC/EDGAR compliance** and refactors the frontend report view to display detailed verification results. ### Key Changes **Backend (`GetInfoOnPDF.java`):** * **VeraPDF Integration:** Replaced the custom `checkForStandard` and `validatePdfAWithPreflight` methods with `VeraPDFService.validatePDF()`. This aligns validation with industry standards. * **Code Cleanup:** Removed approximately ~200 lines of technical debt, including raw XML regex parsing and file-locking prone `PreflightParser` logic. * **SEC Compliance:** Added `isSECCompliant()` logic to validate documents against typical EDGAR requirements: * No Encryption. * No Active Content (JavaScript). * No External Links. * No Embedded Files. * No AcroForms. **Frontend (`GetPdfInfo`):** * **New Component:** Created `ComplianceSection.tsx` to handle the complexity of compliance reporting. * **Enhanced UI:** * Added visual badges (Passed/Failed/Not Detected) using `CheckIcon`/`CloseIcon`. * Added support for displaying the detailed VeraPDF summary alongside legacy boolean flags. * Improved handling of "Not PDF/A" states. ### Motivation The previous validation logic was prone to false positives/negatives and memory issues with large files (due to Preflight). Moving to VeraPDF provides accurate, profile-based validation (e.g., PDF/A-1b, 2b, etc.). The SEC check satisfies a growing need for users validating documents for financial filings. <!-- Please provide a summary of the changes, including: - What was changed - Why the change was made - Any challenges encountered Closes #(issue_number) --> --- ## Checklist ### General - [X] I have read the [Contribution Guidelines](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/CONTRIBUTING.md) - [X] I have read the [Stirling-PDF Developer Guide](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/devGuide/DeveloperGuide.md) (if applicable) - [ ] I have read the [How to add new languages to Stirling-PDF](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/devGuide/HowToAddNewLanguage.md) (if applicable) - [X] I have performed a self-review of my own code - [X] My changes generate no new warnings ### Documentation - [ ] I have updated relevant docs on [Stirling-PDF's doc repo](https://github.com/Stirling-Tools/Stirling-Tools.github.io/blob/main/docs/) (if functionality has heavily changed) - [ ] I have read the section [Add New Translation Tags](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/devGuide/HowToAddNewLanguage.md#add-new-translation-tags) (for new translation tags only) ### Translations (if applicable) - [ ] I ran [`scripts/counter_translation.py`](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/docs/counter_translation.md) ### UI Changes (if applicable) - [X] Screenshots or videos demonstrating the UI changes are attached (e.g., as comments or direct attachments in the PR) ### Testing (if applicable) - [X] I have tested my changes locally.
