Executive summary
power-two-square-rays is the former location of a weekend visualization experiment. The current public repository is archived and contains one notice rather than an active implementation. That notice directs readers to p2-odd-rays-visual-math-toy, where the exploratory code and notes were retained. It appears in this catalog to account for the full public repository list and make the move clear. It is not a second implementation or an additional research result.
Evidence and boundaries
The reviewed default branch tracks only README.md, and GitHub's repository metadata marks it archived. The notice makes no performance, engineering, optimization, or production-readiness claim. No implementation or test metrics are attributed to this repository.
Where to continue
Open the related p2-odd-rays-visual-math-toy brief for the retained generators, images, construction, and limitations. There is nothing to build in the current archive-notice repository.
