Month: 2026-01 This period delivered cross-repo reliability improvements through CI/CD enhancements and a critical type-safety fix. In tracel-ai/burn, macOS CI was enabled and moved into the normal CI pipeline, and Metal backend tests were activated in CI. These changes included dependency updates and documentation of disabled tests with explicit issue links to guide follow-up work, improving test visibility and maintainability. In tracel-ai/cubecl, a type-safety fix for the Remainder implementation prevents float-to-int narrowing, reducing the risk of runtime errors. The combined work strengthens cross-platform validation, accelerates feedback loops, and improves overall code quality for macOS/Metal environments and numerical safety in core math paths. Key achievements: - Enabled macOS CI in burn's normal CI pipeline, ensuring macOS builds/tests run after code quality checks (commit 6f53c9036b514fe25bf9c5311568cb6a87d226b7). - Enabled Metal backend tests in burn CI, with issue-linked documentation and dependencies updates (commit c45428c6cc21efb8791ec6def7b506657f8ba3c5). - Documented disabled tests and tracked issues for follow-up (part of burn CI changes). - Fixed float-to-int narrowing in cubecl's Remainder implementation, improving type safety and runtime stability (commit a3987c60e410d77b6b38e99d1c2a6bc0979d38ba).
