Source for Strong Papadimitriou–Ratajczak Conjecture
This pinned Lean source formalizes the following mathematical result: A paper and pinned Lean package give a proof candidate that every finite simple 3-connected plane graph has a convex greedy straight-line drawing preserving its prescribed embedding and outer face.

Each ZIP contains the checked first-party local Lean import closure, exact statements and boundaries, license, notice, evidence, a source-footprint manifest, and continuation data. Mathlib and other third-party dependencies are not bundled; this is not a portable whole-repository release.
Line counts exclude blank lines; comments and documentation count. The total is the deduplicated, commit-pinned first-party Lean import closure; Mathlib and other third-party dependencies are excluded. Declaration count means names covered by the artifact's recorded evidence, not every declaration in the source. Source footprint is not a difficulty or proof-quality score.

Every listed file is read from the same pinned Git commit. File links open raw source in a new tab; use the ZIP download for the complete package. External Mathlib modules are dependency-locked but are not copied into this first-party source tree.
The endpoint and every listed local import come from the exact recorded Git commit, and the endpoint matches the stored source hash byte for byte. The locally authored package material is licensed under Apache-2.0 by Lech Mazur; Mathlib and cited third-party material remain under their own terms. Machine-readable checker evidence is included.
