Import planar Euclidean dual-geodesic midpoint rigidity - #656
Conversation

Advisory cross-file review against Lean Pool's supervisory rubric. This is not by itself a significance, source-verification, or merge verdict. [Low impact] No blocking issue remains in the changes since the previous review; the external-source checks remain unverified. SummaryImports planar dual-geodesic midpoint rigidity, its differentiable obstruction theorem, and the five-direction criterion, with the supporting geodesic and tensor proofs.

| Rubric | Verdict | Bottom line |
|---|---|---|
| Faithfulness | ✅ pass |
All four card headlines match the Lean statements and their disclosed assumptions. |
| Novelty | ✅ pass |
No duplicate of the four headlines was identified in the searched corpora; exhaustive semantic coverage of Tau Ceti remains unverifiable. |
| Significance | ✅ pass |
The completed planar rigidity theorem and its supporting geodesic analysis constitute a research-level project worth preserving. |
| Sources | ✅ pass |
The paper’s §9 supports the conjecture and obstruction attribution, while the pinned upstream contains the separately credited planar proof and advertised refinements. |
| Code quality (advisory) | ✅ pass |
The modules separate polynomial certificates, analytic estimates, and geometric assembly coherently, with no material maintenance issue requiring discussion. |

Statement check: On open preconnected planar domains, canonical dual-midpoint complementarity forces constancy for C² fields; differentiability suffices under the stated obstruction criterion, including its five-direction version.
The development establishes planar dual-geodesic midpoint rigidity, addressing Nielsen–Okamura Conjecture 9.1, through fourth-order approximation, exceptional-tensor classification, and a differentiable obstruction theorem.

Reviewed the complete 32-file change at The geometric theorem proves planar necessity from complementarity of actual canonical local dual-geodesic midpoints. Short-geodesic existence and uniqueness, the fourth-order obstruction bridge, exceptional tensors and zero-trace transitions are proved. The C² strengthening and the differentiable obstruction/five-direction criteria retain their stated hypotheses at every spatial point. Fixed-frame covariance is kept separate from differentiation. I found no hidden assumption of the desired rigidity or remaining concrete quality issue. The paper’s Section 9 supplies the conjecture and obstruction background; the card correctly attributes the new planar proof to the pinned upstream. Its MIT license, retained notice and AI provenance were verified independently. Bounded comparisons against pinned Mathlib and current Tau Ceti The generated wrapper covers all 30 production modules, the import graph is acyclic, and the fixed pool root and gates are unchanged. Current-head CI has all 28 contexts complete and green. Configured job 2126 independently published Source accepted for integration through the normal protected native queue. Merge-group CI and all protections remain required. |

This imports the completed planar case of Nielsen–Okamura Conjecture 9.1: complementary canonical local midpoints of the Euclidean dual connections force the cubic coefficient field to be constant on an open preconnected planar domain. It includes the C² geometric theorem, the differentiable obstruction theorem, and the five-direction criterion. No claim is made in higher dimensions.
The preservation value includes a bounded Dirichlet Green operator, a general contraction theorem on continuous path balls, quantitative boundary-value stability, canonical short-geodesic existence and germ uniqueness, Taylor remainder estimates, and the full classification of the exceptional planar tensors. The geometric hypothesis contains the actual position/velocity ODE, endpoint conditions, shortness and uniqueness; the quartic obstruction is derived rather than assumed in the geometric theorem.

Imports.leanand one YAML card. Independent upstream Challenge/Solution files, workflows and other tooling are excluded.LeanPool.leanis unchanged. No matching project/card/PR/history entry or matching endpoint was found in the pool, Mathlib or Tau Ceti. The nearest inspected Tau Ceti geodesic API concerns Levi-Civita geodesics, rather than rigidity for general Euclidean dual affine connections; midpoint convexity is also a different result.Porting keeps all theorem strengths and definitions. Imports are relocated under
LeanPool; umbrellaMathlib/Mathlib.Tacticimports are replaced with specific imports. All heartbeat/recursion overrides are removed. Public definitions are documented, warnings and style issues repaired, and a typed intermediate derivative replaces a costlyconvertin the spatial Taylor proof. No gate/configuration, suppression or waiver is added. Greptile identified duplicated five-direction interpolation;kernel_of_five_arrayObstruction_zeronow supplies that argument to both proof sites, with the relevant checks rerun.The build commands were
/usr/bin/time -v lake build LeanPool.PlanarMidpointand/usr/bin/time -v lake --wfail build LeanPool.PlanarMidpoint, with only project artifacts absent, the same prebuilt dependency oleans, Lean v4.35.0-rc3, and Mathlib c55e6e786f49471c72fbddbec5415808896aec1e. This is a shared Azure VM: OS caches and host load were not controlled, so wall time and RSS are indicative. Synchronous command profiling (Elab.async=false,trace.Elab.command=true,trace.profiler=true,trace.profiler.useHeartbeats=true) isolates the approximately 20× declaration improvement. The original benchmark retains the upstream resource override; the final code has none. Largest initial modules included Algebra (38 s), Covariance (32 s) and SpatialTaylor (26 s); SpatialTaylor builds in about 5 s after repair.Local validation:
