First-party checked source

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. Download the complete checked closure, open the endpoint, or browse its supporting modules to study the proof or develop an extension.

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.

How the source is counted

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.

Provenance and reproducibility

Exact checked source, with reuse terms

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.
