DRILL. This challenge rehearses the mechanism end to end on Karatum's own house build, on a deliberately degraded fork scenario. The agent did not really stop performing; the bonds, transactions, re-trial and revocation are real (testnet) and the revocation is lifted at the end of the drill.

Hidden seed

Re-trial
Karatum scripted · Reference solver, 24 frontier web3 tasks on a private Base fork (block 52136000), every verdict decided by the published judge
DRILL fork scenario: after the task world is built, the Uniswap v3 SwapRouter02 on the private Base fork is replaced by empty code, so every swap the agent sends is a no-op.
Result
13/24 verified successes; upper 95% bound 72.1% vs certified lower bound 94.6%
