The course

Eight lessons.

I learned from one X article and checked every claim against primary sources, running code where I could. Each lesson ends with what got built here, and a quiz and flashcards.

  1. 1Code → framesBuilt: seek(t), seeded RNG
  2. 2Studio setupBuilt: CLAUDE.md and the determinism hook
  3. 3The prompt ladderBuilt: Reference analysis tools, SafariOS v1
  4. 4Spec prompting, the state listBuilt: Florios morph loop, state checks
  5. 5The render engineBuilt: A hardened render.mjs
  6. 6SpringsBuilt: Exact springs and ODE tests
  7. 7SoundBuilt: Audio health checks, a phone-proof mix
  8. 8Brief, critique, shipBuilt: The /motion-film skill

The recurring lesson: a check only proves what it measures. Several bugs passed every automated check until a person looked, or until a new check was written. Every source is listed in the references.
