Scope clarification: 2026-09-17 exact-head reconciliation: Reviewed Changes requested by automated review — independently reviewed The unconditional 0.6934 upper bound is independently significant progress on Besicovitch's 1/2-problem. sigmaOne_plane_le_barS has no Gram-certificate premise: weightedGeometricBound_gram and six-point transfer discharge it. Primary upstream supports this improved bound; Apache-2.0 and AI provenance verified. No matching pool entry. Registry still uses status draft and nonexistent Besicovitch.* names instead of actual LeanPool.Besicovitch declarations. Repair deprecated Basic/if_pos/if_neg and other warning failures, correct status to verified and registered declaration names/card, then obtain complete exact-head warning-free quality/trust CI. These are concrete author actions; draft is not the blocker. Existing change-request comment updated in place. Advisory project build 439.07 s; serial profile 1,375.06 s, dominated by certificates and endpoint geometry. This run’s build at 3493526 logged 166 Lean-warning entries across 32 files and failed the zero-warning gate. The final main refresh changes no Besicovitch files; its new CI is pending. Final-head reconciliation: the main refresh contains the already-reviewed Komlós import/Burkholder refactor and generated metadata. This PR’s own proof/tooling files are unchanged by that refresh. Fresh checks on refreshed heads remain the required gate; earlier successful runs are historical evidence, not an approval of pending CI. Repository auto-merge remains disabled. The linked disposition is the final action; no protection or workflow setting was changed. |

Changes requested by automated reviewReviewed head
Review coverage: complete changed-file inventory and full diff retained; 100 changed project files, 27,149 lines, import reachability and executable trust-token scan; advertised endpoints and supporting definitions examined with bounded implementation sampling and existing review findings reconciled. Potential reusable value: Quantitative geometric certificate and disk-covering estimates. Source/provenance and prior-art evidence were considered separately from CI; these findings do not assert that every proof line was manually read. Earlier automated scores are advisory and are not approval of this failing head. |

Reviewed current head 8e07d9829ffed437e678bd35bfb40b240a7fd94d. Recommendation: approve, subject to fresh required CI.
The headline is the unconditional bound sigmaOne_plane_le_barS : sigmaOne (EuclideanSpace ℝ (Fin 2)) ≤ 6934 / 10000. The finite-configuration certificate and measure/rectifiability arguments are supplied within the development. This is a substantial quantitative result; it does not claim to settle the 1/2 conjecture.
The concrete maintenance findings are repaired: BPC/Defs modules now have full names; the unused duplicate RationalExpression syntax/evaluator/enclosure proof is removed while the rational interval primitives and richer radical certificates remain; RootEdge reuses the three existing norm/endpoint estimates. All headline statements are unchanged. The latest main merge preserves every current main registry card and adds only this project's card.
Validation: the repaired project build completed successfully (3,261 build jobs); the scoped quality and compiled trust audit checked 100 files and 1,046 public declarations without errors. After recovery, the project-only linter, style checker, generated-index check, and downstream public-import/headline check all passed under a 20 GiB aggregate memory cap and timeout. The umbrella transitively imports all 99 project modules, so its scoped linter covers the complete project import closure. Full-pool CI is pending on this pushed head; no check or waiver was changed.

Reviewed current integration head 4f34a72a527b903e0dd1197a25fa6100ddf5e70c. The project's Lean source is byte-identical to the previously reviewed 8e07d9829ffed437e678bd35bfb40b240a7fd94d; the existing mathematical assessment and fixes carry forward. The merge retains all 218 current-main project cards and this project's complete card, including their original text. The actual pinned mk_all --module --check command passes.
Recommendation: accept once fresh required CI passes. This review covers the lossless main integration; it does not claim another full local rebuild.

Imports Yongxi Lin’s Besicovitch formalization into
LeanPool.Besicovitch. The unconditional headline issigmaOne_plane_le_barS : sigmaOne (EuclideanSpace ℝ (Fin 2)) ≤ 6934 / 10000, supported by the finite-configuration certificates and measure/rectifiability arguments. This does not settle the 1/2 conjecture.17c9597b2a901bf386d5bb8382d0a74d2069f25b.The import contains 99 project modules and its entry module. Porting and maintenance repairs are complete: imports and finite instances follow the pinned APIs; resource-limit overrides are removed; modules have full names; unused interval-expression scaffolding is removed; and norm, packing and matrix-certificate proofs reuse shared implementations. The numerical certificates and headline statements are preserved. The complete acceptance review and latest matrix-consolidation review recommend approval subject to required CI.
Validation at the earlier repaired head
8e07d982included a successful 3,261-job build, scoped quality and compiled trust checks over 100 files and 1,046 public declarations, plus project lint, style, generated-index and public-import/headline checks. The subsequent matrix consolidation received source review; no fresh local compilation is claimed for that review.Current head
9dbd9e5aintegrates only a generated README update from main; all 100 project source files, the registry and index remain unchanged. All three required checks have passed at this head: Lean CI, documentation preflight and content separation. The current CI run also passed compilation, challenge/solution builds, declaration lint, text style and repository quality checks. No checks or waivers were changed.
