How documents are verified

Public pages show verified study metadata and sanitized stored PDFs. Discovery provenance is kept privately for administrator auditing, duplicate detection and future maintenance.

What we verify

• The file has a valid PDF signature and opens successfully.
• Its size, page count and hashes are recorded when the file is collected and after sanitization.
• Interactive PDF links, JavaScript, launch actions and external actions are removed before publication.
• Question papers, marking schemes and evaluation reports remain distinctly labelled.

Independence

This is an independent educational resource and is not the official Department of Examinations website. When document authority is confidently verified, the public record may identify it as Department of Examinations, Sri Lanka.
