v4.0.0 is withdrawn, and the G3 v3.0.0 cohort of record is current again. Its best individual is hz4i013_g00995_d206e3c9: W_ERGOLIGHT_v1 draft d 80.55, 59.3 g print mesh. It is a computational design; it has not been built or tested, and several safety factors are below 1. The v4.0.0 release remains published, marked WITHDRAWN, with the reasons.

Why v4.0.0 is withdrawn (owner decision, 2026-10-27):

  • Not evolved. Every population, including the "Sobol" baseline, was seeded with a hand-authored genome, and hand-coded rules pushed named genes toward chosen values.
  • Not under the owner's loads. It used a 0.80 N·m tip twist instead of 1.82 N·m, judged the spine case on ultimate strength, and assumed HIP material.
  • Not computed as claimed. The lateral capacity is a stress clamp, the plate convergence study is synthesized, the tip safety factor at the RS-v3 load is 0.161, and the exported CAD was scaled to the scored mass.
  • Not reviewed. It was merged 60 s after the PR opened.

G3 errata and diagnostics. The receipt is unchanged. New diagnostics live in evidence/g3/v3.0.0/diagnostics/:

  • the yield sequence per load case is 2.74 / 5.06 / 0.52;
  • fatigue with the knock-down applied once is 1.06;
  • the solid tip with the raster offset removed is SF 0.55, and the point is blunt;
  • the plate capacities do not converge under mesh refinement (337 / 191 / 254 / 103 N);
  • the paper now gives four masses.

Wording corrected in the paper and README:

  • the tip load is a twist, not a pry;
  • the tip mesh study is non-monotone;
  • no genome was edited by hand, but the decoder, objective and rules are human-authored;
  • 1 % of E is worth 2.3 g of mass;
  • the process is L-PBF, not "printable";
  • niche centres are Halton points, not a CVT;
  • the FE run is a voxel FE check, not a certification.

The provenance of RS-karambit-v3 is recorded in docs/g3/provenance/. Attached: the G3 paper g3-v4.0.1.pdf. The CAD is on the v3.0.0 release and in cad/. Full notes are in docs/RELEASES.md.
