First-party checked source

Source for Napoleon’s Theorem — Algebraic Core

This pinned Lean source formalizes the following mathematical result: Given three complex points and ω² − ω + 1 = 0, the centroids of consistently oriented equilateral constructions on their sides form an equilateral triple. Download the complete checked closure or open its single Lean endpoint 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 an agent continuation file. Mathlib and other third-party dependencies are not bundled; this is not a portable whole-repository release.

How counting works: 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; it is not a count of 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.
