The tab headers carried their file names as fixed text - "Additional personal details · EF_DG11" - so a Polish passport, which ships DG13 and no DG11, was told its details came from a file it does not carry. The ISSUER header claimed EF_DG12 on the same document, and SECURITY listed EF_DG15 whether or not it was there. personal_files, document_files and security_files report what each tab drew from, and the pages compose their header from those. They sit on the record rather than in the widgets so they can be tested without a display, which is how the rest of the suite is built. PERSONAL names EF_DG1 when the personal number came from the MRZ, that being the file which supplied it, rather than crediting DG11 for a value DG11 did not provide. With nothing read the header stays the bare description: the record is an empty PassportRecord at startup rather than None, and reporting an absence on a chip nobody read reads as a fault. "none present" rather than "nothing on this chip", since the app opens offline dumps too. The same document showed the other half of this: "Personal number (from DG13)" renders 203px against a dp(190) caption column, so it wrapped and left the source on a line of its own. Without the "from" it is 167px. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
