TCPDF reads as a downstream re-saver — it surfaces disproportionately on documents whose original Creator was a different, often institutional, application.

Corpus profile
TCPDF is a PHP PDF library used for both legitimate server-side document generation and ad-hoc PHP-stack PDF utilities.
TCPDF often is the original generator. Contextual signal: producer/creator mismatch on otherwise institutional documents.
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 TCPDF in the wild. All are merged into the same canonical profile.
Why variants matter
The same tool publishes itself under 9 different metadata strings — version bumps, locale tags, build IDs. We canonicalize them so the corpus reflects one identity, not noise.
Distributions
The PDF versions TCPDF writes when acting as Producer, and the other tools that appear in the same documents.
Related profiles
Other tools that frequently share metadata with TCPDF in the same documents. Each card links to its own forensic profile.
Long tail
Smaller cuts of the TCPDF corpus — useful context, but treat each row as a single data point rather than a strong signal.
