Regenerates README statistics and NOTICE from the accepted project cards and attribution notes. No proof sources change.

Advisory cross-file review against Lean Pool's supervisory rubric. This is not by itself a significance, source-verification, or merge verdict.

[Low impact] This metadata-only PR appears safe to merge.

Summary

Refreshes generated metadata without changing proof sources.

• The README totals and MIT project list now include PlanarMidpoint.

Upstream license text was not independently verified. The formalization review dimensions do not apply because this PR changes no formalization.

Reviewed 587bff430ec05cc364d4a18b07fe871211c6f0c7. The two generated changes match accepted PR656: one project card and exactly 4,182 added Lean lines (4,144 production lines plus the 38-line import wrapper), together with the correct PlanarMidpoint upstream attribution. The statistics, attribution generator and metadata workflow blobs are unchanged. The existing absolute statistics baseline was inherited; the new increment was checked directly against all 31 accepted Lean files.

The metadata content is accepted. Current main 3c52e024 still has pending post-merge CI, so I disabled this PR’s existing auto-merge request to preserve the required green-main hold. Integration remains pending verified green current main, this exact head’s required checks, and the existing automated review. No branch, proof, workflow or gate change was made, and no duplicate review request is needed.

Verdict: ✅ approve

This refreshes the README totals and adds the existing PlanarMidpoint project to NOTICE. The 4,182-line increment matches its 31 Lean files, and the NOTICE entry matches its project card and generator format. Only these two metadata files change. The inherited absolute totals were not revalidated; no Lean build was run.

Aspect	Value
