Tool profile

Stimulsoft Reports

Stimulsoft Reports 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

How Stimulsoft Reports shows up in HTPBE? corpus

Stimulsoft Reports is one of the PDF-handling tools surfaced in the HTPBE? corpus. Stimulsoft Reports splits its occurrences between Creator (67%) and Producer (33%) roles, meaning it sometimes originates documents and sometimes re-emits them after another tool created them.

In the HTPBE? corpus the contextual signal we look for is a producer/creator mismatch: when Stimulsoft Reports 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 Stimulsoft Reports acts as Creator, 50% 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 Stimulsoft Reports or its users.

Role in the workflow

How Stimulsoft Reports shows up in metadata

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.

How to read this

The Creator slot typically reflects where a document started life. The Producer slot reflects whatever wrote the bytes — and is the field that gets overwritten when a PDF is opened, edited, and saved by a downstream tool.

A higher modification rate as Producer than as Creator usually means the tool is acting as a re-saver on documents that originated elsewhere. A higher rate as Creator points to fragile workflows around the original authoring app.

Why variants matter

The same tool publishes itself under 3 different metadata strings — version bumps, locale tags, build IDs. We canonicalize them so the corpus reflects one identity, not noise.

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