The rejection message of a code-submission response: the executable's write
to the enter-code error slot — the adjacent-arg pair whose key is the slot
and whose value is the non-empty server message. Anchored on the semantic
slot key alone, never on an opcode name; the same read the registration
error detector uses for its own slots.
