Definitely not! There is zero MuPDF code, FFI, or transpilation in PaperPilot.

The core PDF parsing and AST manipulation is built on pure Rust libraries: lopdf (0.45), pdf-writer, hayro, and image. All of these are Apache 2.0 or MIT licensed.

Any mention of MuPDF in the documentation/planning notes was strictly part of an architectural trade-off analysis (evaluating existing Python/C extraction pipelines like PyMuPDF vs. pure Rust). The entire crate stack in paperpilot-pdf is 100% Apache 2.0 / MIT clean.
