Wayfinder Education Engine

The only executable code in the Wayfinder platform. A unified sandbox for Math, Science, Finance, Reading, and Data analysis — every answer computed explicitly and verified, never hallucinated. A real bug was found in the self-test and fixed before this page was published.

PurposeProvide verified, non-hallucinated computation for any Wayfinder module — every operation returns (answer, verification, error_detection, remediation_path, channel_log).

A real bug, found and fixed before this went live

The self-test hardcoded a simulated student answer of '3/4' — which matches the actual correct answer computed the line above it — but also hardcoded is_correct=False. That contradiction made the progress summary report 0% accuracy on a correct answer, with a phantom error-taxonomy entry. Fixed to is_correct=True, matching what the code actually computed. Re-run and confirmed consistent below.

How this is meant to be used

Point your own AI assistant at this page and ask it to use this engine for real GED assignment generation — it can read the source below, run it, and call into MathSandbox, ScienceSandbox, ReadingSandbox, or DataSandbox directly for any calculation that needs to be verified rather than guessed. See the Math Sandbox Protocols and Prompt Templates for how the GED module specifically wires into it.

Independently checked by hand, not just trusted: 1/4+1/2=3/4 ✓, KE=½mv²=½(5)(10²)=250J ✓, $1000 at 5% monthly-compounded over 10 years = $1647.01 ✓, Pearson correlation of those two arrays = 0.853 ✓. The progress summary is now internally consistent — 1 correct attempt, 100% accuracy, no phantom error entries.
