what works.

OmniLab is a computational instrument for perturbation-based learning. Start from working code. Predict what one change does. Run it. Reflect on the divergence.

The method · four moves, infinite worlds

Most platforms ask you to memorize.
We ask you to perturb, predict,
and reconcile the difference.

  1. 01 / PREDICT

    State a hypothesis

    Read the original. Predict the output before you run it. Commit the prediction in writing.

  2. 02 / MUTATE

    Mutate one variable

    Change a single operator, line, or parameter. The instrument tracks the divergence character by character.

  3. 03 / DIVERGE

    Observe both worlds

    Run in Pyodide. The system shows two outputs side by side, plus the precise Δ between them.

  4. 04 / RECONCILE

    Reconcile with theory

    The Socratic Coach asks why — not what. You write the explanation. Mastery is earned.
