The price guard capped at the proven price

With the price guard limited to the price proven across the chains, does it still stop the sawtooth attack and leave the ordinary market alone?

WithheldWithheld (7) A weakness the run found is not fixed yet. Its verdict and evidence publish when the fix lands.

What this proves

  • Whether, in these runs, the capped guard held against the attack, how the ordinary market fared under it, and whether the quick scenarios still passed.

What it does not

  • Behaviour in markets unlike the lab's simulated one.
  • The model's own judgment: model answers are scripted.

What broke, what was fixed

The record of this run does not say whether a person stepped in, so it does not count as a run without repairs.

Cost in tokens

Not recorded: this run has no chain-derived scorecard.

Archived evidence

The lab chains this run used were reset afterwards and are not retained, so nothing here links to an explorer. The record below is the archived copy.
