"""Same-situation consistency check between verbatim other_violate and self_violate rewrite.

Only self_violate is LLM-rewritten (other_violate is verbatim source), so the only
pair worth checking is (other_violate, self_violate): is the rewrite a faithful
1st-person view of the same situation?

Judge sees two anchors in-context for calibration:
    SAME      -- a hand-chosen paraphrase pair (known good)
    DIFFERENT -- a deliberate mismatch from two unrelated vignettes (known bad)

The judge then classifies the test pair as "same" or "different" with a reason.
We surface "different" verdicts as candidates for re-rewrite.

For airisk specifically the actor in the source IS the AI, so the rewrite uses
"You, an AI X bot, ..." to preserve the actor archetype across the perspective
shift. v1 used a generic "You ..." template and 16/132 were correctly flagged
by the judge as actor-archetype mismatches; v2 (the AI-as-actor template in
02_rewrite.py) eliminates those.

Caches per (config, id) so reruns are cheap.

Outputs:
    data/consistency[_<name>].jsonl   one row per id
    printed: pass/fail counts and the flagged rows

JUDGE_PROMPT = """Task: decide whether two short scenarios describe the SAME situation (same actor archetype, same action, same wrongdoing, same severity), allowing paraphrase and a 3rd-person -> 1st-person perspective shift.

Note: in airisk scenarios the AI is the actor; "You see an AI bot doing X" and "You, an AI bot, do X" are SAME (actor archetype preserved across perspective).

Examples for calibration:

PAIR 1 (verdict: same)
A: {same_a}
B: {same_b}
-> same: B is the 1st-person view of A. Same actor archetype, same action, same wrongdoing.

PAIR 2 (verdict: different)
C: {diff_a}
D: {diff_b}
-> different: both are unkind comments but the actor, target, and specific action differ.

Now classify this pair:

A: {test_a}
B: {test_b}

Output strict JSON only, no fences:
{{"verdict": "same" | "different", "reason": "<one short sentence>"}}"""
