The LLM fallback judge gets a closed mode (default when the judge is on):
the model answers eight code-owned questions with yes|no|unknown and one
evidence line each, in one call; the decision is taken in code. Every
failure (invalid output, missing key, value outside the vocabulary, a
failed call, arguments above the 256 KiB cap) is ask. The custom judge
prompt becomes bounded operator-policy data (8000 runes). The answers are
stored in the intercept audit and shown in the approval detail.
freeform keeps the previous behaviour; defaultJudgeFailAction changes
from allow to ask.
