- lean-toolchain: v4.21.0-rc3 -> v4.27.0 - lakefile.toml: pin mathlib to v4.27.0 - Delete lake-manifest.json (Lake regenerates) - cubical_sperner_prep: add import Mathlib.Tactic; close new implicit-arg side goals (hn1) in 5 places - cubical_sperner: close hn1 side goal; fix simp for Set.MapsTo - apply_cubical_sperner: annotate tendsto_one_div with (R : Real) for new ContinuousSMul typeclass - kakutani: same tendsto_one_div annotation - brouwer: replace removed EquivLike.inv_apply_eq_iff_eq_apply with explicit symm_apply_apply proof Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Replace ~37 verbose Nat/Fin arithmetic proofs with `omega` - Fix 3 deprecated names: Finset.filter_False -> filter_false, Function.Surjective.injective_of_fintype -> injective_of_finite, div_add_div_same -> add_div - Remove 13 unused simp arguments flagged by linter - Net -53 lines, zero warnings Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
cubical_sperner_prep and cubical_sperner imported SimpleGraph.DegreeSum and SimpleGraph.Clique but never used them. Removing saves 21 build jobs. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Replace 25-line affine span argument with 7-line proof using interior_pi_set and interior_Icc to show the unit cube has nonempty interior. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Fix proofs broken by v4.29 tactic regressions: - `rw` on Iff no longer matches in `convex_homeos`; use `.mpr` directly. - `rwa` with Finset-coe membership no longer unfolds in `cubical_sperner`; construct the membership explicitly via `Finset.mem_coe` + `Finset.mem_filter`.
