Searchable PDF sample, checked 2026-10-11.

source.pdf is a self-authored, one-page digital image-only handout reused from the earlier reviewed OCR task. native-searchable.pdf is the unmodified native export using the option labelled 扫描 PDF 添加文本层. The TXT files were independently extracted using pypdf/PDFium; they are not clipboard captures. Source text is empty. Output text includes linearized formula and literal HTML table markup. The visible PDF image is retained, but this does not establish editable table cells, precise text selection alignment or universal copy order. See checks.json for measured search, structure, render, scope and browser limits. This ZIP was assembled locally.
