If you’ve been following our nightly commits on the fractal-core branch, you might have noticed a quiet but significant bump this morning. We’ve officially rolled out to the production pipeline. If you find a regression in the new

This isn't just a patch for a typo in a comment. This update tackles a decade-old assumption about how we handle floating-point instability in high-iteration environments. Let’s break down what complex_4627 actually is, and why v1.03 might be the most boring—and therefore most exciting—release of the quarter. For the uninitiated, complex_4627 is our internal, hardware-agnostic library for arbitrary-precision complex number arithmetic. Where standard libraries (looking at you, libcomplex.so ) start to hallucinate after 10^6 iterations, complex_4627 was built to track phase, magnitude, and computational entropy up to 10^15 iterations.
