- Manual participant entry for paper tests: name + correct answers →
register entry with source 'paper' (app runs are tagged 'app')
- Scan upload per register entry: marked paper sheets (image/PDF,
max 1 MB) stored locally as data URL and anchored with a SHA-256
checksum of the original file; view scan in-app, checksum shown
- Document verification: certificate and training register printouts
carry a SHA-256 checksum footer over the document content — a
presented printout can be re-verified against the tool; certificate
additionally references its register entry ID (evidence chain
certificate ↔ register ↔ scan)
- Register printout extended with source, evidence checksum and ID
columns; record deletion with confirmation warning
- UI labels in all nine languages; 73 tests green
