Aspose 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
Aspose is a commercial component suite (Aspose.PDF, Aspose.Words) used both for legitimate server-side document generation in enterprise apps and for programmatic editing/conversion of existing PDFs.
Aspose appears across both legitimate first-generation output and re-save flows. Signal: when Aspose is the latest Producer on a document whose Creator was an institutional source, that producer/creator mismatch is one of the markers we surface — together with any incremental-update or signature-removal evidence on the file.
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.
Name fingerprints
Different version strings and spellings observed for Aspose in the wild. All are merged into the same canonical profile.
Why variants matter
The same tool publishes itself under 17 different metadata strings — version bumps, locale tags, build IDs. We canonicalize them so the corpus reflects one identity, not noise.
Distributions
The PDF versions Aspose writes when acting as Producer, and the other tools that appear in the same documents.
Most output is PDF 1.7 (98% of files where Aspose is the Producer).
Aspose sits upstream in 95% of cases — read this row as “what kinds of documents end up routed through Aspose.”

Long tail
Smaller cuts of the Aspose corpus — useful context, but treat each row as a single data point rather than a strong signal.
