Black Rainbow Labs Builds Software That Can Say “No Answer”

Field notes

The lab frames its software around Alexander's band, the dark interval between primary and secondary rainbows where no wavelength returns light. Its stated implementation constraints are unusually explicit: both projects are written in Rust, run in-process, and do not fetch at runtime; Unluminous bundles SQLite into a single-file, serverless setup. The method section also describes predeclared thresholds, paired statistical tests, and a documentation-drift check as part of deciding whether the work is finished.
