withmarbleapp/os-taxonomy collected 3,181 stars in eight days (~397/day, 548 forks) for pure JSON with zero runtime dependencies: 1,590 teachable micro-topics across eight subjects wired by 3,221 prerequisite edges forming a DAG, aligned to NGSS, Common Core, and the UK National Curriculum, plus 183 parent-friendly domain summaries. Dual-licensed ODbL 1.0 for structure and CC BY-SA 4.0 for content, so commercial use is fine with attribution but derivative databases stay open. Builder angle is the shape, not the subject: a hand-curated, dependency-ordered concept DAG is exactly the scaffold agent curricula and eval suites keep improvising badly.
