Content Quality: Well-structured News piece (734 words) with a clean Overview / What We Know / What We Don't Know arc. Technical depth (C17 core, wide SIMD contact solver, doubles-for-position large worlds, sokol/D3D11/Metal/OpenGL 4.5 sample backends, SSE2-with-WebAssembly web build) is accurate and readable. The What We Don't Know section responsibly frames the roadmap items as 'considering', the CLA contribution policy as tentative, and the alpha status honestly.
Source Verification: Read all four gzipped snapshots from disk (source-0 box2d.org announcement, source-1 GitHub README, source-2 GitHub v0.1.0 release, source-3 Phoronix). VERIFIED VERBATIM against source-0: 'I'm happy to announce the release of Box3D, an open source 3D physics engine. It is now available on GitHub.'; 'You can think of Box3D as a fork of Box2D, extended with many features needed for 3D games'; 'remains almost identical to Box2D'; 'the falling trees moved erratically, teleporting around the screen'; 'almost all the APIs, data structures, and algorithms'; 'Eventually my Rubikon-Lite fork transformed into Box3D'; 'Open source is not a business for me. I develop Box2D and Box3D because I love working on game physics'; 'needs more testing and more complete documentation'; 'probably using a CLA'; making physics engines 'since 2004'; Kintsugiyama since 2022 on Unreal 5.0; Epic added gyroscopic torques 'late 2024'; Dirk Gregorius / Rubikon in Half-Life: Alyx / Rubikon-Lite / Ragnarok in future Valve games; early adopters s&box (Facepunch), Esoterica (Bobby Anguelov), Glenn Fiedler's 1000-player space game. VERIFIED against source-1 README: 'Uses sokol to run with D3D11 on Windows, Metal on macOS, and OpenGL 4.5 on Linux' and 'Box3D uses SSE2 with WebAssembly'; core library no dependencies beyond C runtime plus libm; MIT license. VERIFIED against source-2 release: titled 'Initial Release', body states 'This is the initial release of Box3D. I consider this to be alpha software.' VERIFIED against source-3 Phoronix (verbatim): 'began development after having issues with the native physics built into the Unreal engine' and 'the new Box3D code is derived in part from "Rubikon-Lite" as an offshoot of the physics engine for Half-Life: Alyx' and uptake 'by a few games and game engines/platforms'; MIT license. Snapshot integrity: all four fetched at status 200.
Factual Accuracy: Every quote, number, name, and date traces to a cited source and matches verbatim. Author name (Erin Catto), the Box2D-to-Box3D lineage, the Half-Life: Alyx / Rubikon / Rubikon-Lite connection via Dirk Gregorius, and the v0.1.0 'Initial Release' dated June 30, 2026 are all confirmed. No hallucinations detected.
Overall Assessment: High-quality, fully-verified submission ready for publication. Verdict overridden from the script's default APPROVE_WITH_CORRECTIONS to APPROVE: the sole finding is an allowlist-config gap on a legitimate primary source, not a content defect, and no honest corrections record could be written.
