Detector half-life simulator
Ship a detector and start a clock — the other side begins routing around it the same day.

Synthetic
A synthetic model of an arms race — the shape shared by anti-cheat, fraud, and adversarial robustness. Not real traffic, and not a tool for evading anything.

What it proves
A static detector always loses eventually. Opacity buys time and retraining resets the clock, but neither wins the arms race — and the threshold can't chase forever without flagging legitimate traffic.
How it works
- Evasion is the fraction of adversarial samples that fall below the threshold — it crosses 50% exactly when the attacker's mean crosses below it.
- Opacity slows and adds noise to the attacker's estimate of where the boundary sits, lengthening the half-life without changing the outcome.
- Retraining re-fits the threshold below the attacker's new position, but a floor stops it short of the legitimate cluster to bound false positives.
