Stage 1, live: run the detector on your own code

Paste a Python file. FALSEWORK scans it (no model, nothing executed) and returns its findings and grade. Limited to 30 scans per hour per visitor.

This is the exact forged-token sample from the recorded runs: verify_token says valid: True for any non-empty signature. FALSEWORK flags line 15 as unconditional_verdict. Now replace the last line with return {"valid": hmac.compare_digest(sign(message), signature)} and scan again: the finding goes away. (Checked live on 2026-11-02.)

The demo samples

The four planted-defect samples KEYSTONE ships with, each with its own reference test.

Stages 2 to 4 (model fix, sandbox proof, signing) are not live on the public site right now: live fixing is switched off. The evidence page shows the runs that were actually performed. We do not show a simulated run.
