全行综合账单系统 appears on both legitimate first-generation output and downstream re-save flows — context (the other tool on the same document) is what flips the signal.

Corpus profile
全行综合账单系统 is one of the PDF-handling tools surfaced in the HTPBE? corpus. 全行综合账单系统 appears predominantly as the original Creator (100% of its occurrences) — i.e. on documents that started life inside 全行综合账单系统 rather than passing through it as a downstream re-saver.
In the HTPBE? corpus the contextual signal we look for is a producer/creator mismatch: when 全行综合账单系统 appears as the latest Producer on a document whose Creator was an institutional source (e.g. Adobe PDF Library, Microsoft Word, a banking back-end), the document was rebuilt or re-saved after its original creation. That mismatch is the marker — never the tool itself.
On documents where 全行综合账单系统 acts as Creator, 4% carry modification markers; on documents where it acts as Producer, 0% do. These are observed rates inside the HTPBE? corpus and should be read as base-rates, not as accusations against 全行综合账单系统 or its users.
Role in the workflow
Every PDF carries a Creator (the application that produced the original document) and a Producer (the engine that wrote the PDF). The same tool can appear in either slot, with very different modification profiles.
