MalformedArgument(String)

The stored value is not JSON.

IncompatibleArgument(String)

The stored value does not fit the finalizer’s parameter type, as value as T would reject it.

Denied(Denial)

A runtime denial escaped the cleanup.

BudgetExhausted(Error)

Fuel, the deadline or memory ran out.

Failed(Error)

An initializer or the finalizer threw or trapped.
