Thrown while a chunked restore is still in flight, so no caller can execute PHP through a heap
that is the right length and the wrong bytes.
A named error rather than a boolean return because ensurePhp() has roughly a dozen call sites
and a flag only works if every one of them remembers to read it. LAZY_MOUNT spent its entire
life as unreachable code behind exactly that kind of unchecked condition.
