Intercept judge: closed-question mode, fail-closed to ask
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.
