EntryPoint Error AA26 over verificationGasLimit
The account's validation (account creation, validateUserOp and the prefund payment) used more gas than the user operation's verificationGasLimit. This is the EntryPoint v0.7+ equivalent of AA40.
Increase verificationGasLimit. A common cause is estimating gas with a dummy signature that takes a cheaper validation path than the real signature, for example a passkey stub whose key ID is not registered on the account, or whose challenge does not match, so the validator exits before verifying the signature. Use a dummy signature that runs the same validation steps as the real one, or add a margin to the estimated verificationGasLimit.
