Source: Cubemuch, https://cubemuch.com/en/algs/fto/1lll/, retrieved 2026-10-29: case names and groups, and each case's algorithms: those credited to the community sheets it cites first, in its order, then those its search found, best-scored first (no votes or setups). The source's first six verified alternatives per case are retained; further generated variants are omitted to keep case pages and the client bundle bounded. Every algorithm shown was checked by the logic engine; rejected ones are listed in docs/db-exclusions.md.
