no-magic ships 47 single-file AI algorithms

This is less a repo than a full AI textbook disguised as code, and the constraint system is the real product: one file, stdlib only, and commentary that explains the math instead of hiding it.

• –The single-file rule removes framework noise, so readers can see the algorithmic mechanics without jumping across helpers or dependencies.
• –The coverage is unusually broad, spanning foundations, alignment, systems, and agents, which makes it useful as a map of the modern AI stack, not just a grab bag of demos.
• –The learning layer matters: 7 paths, 182 flashcards, challenge prompts, EPUB export, and translations turn the repo into something you can actually teach from.
• –The tradeoff is maintenance at scale; 47 hand-rolled implementations plus docs and translations will only stay trustworthy if the repo keeps getting careful review.
