"""
every detector on one row, next to what the checks found (no model, about 1 minute).

    python experiments/detector-sanity-checks/headline.py

The pre-registered headline table has four columns per detector:
    (i)   the detector's AUROC on its main set, the number its source would quote;
    (ii)  the best lexical baseline on that set (keyword rules and bags of words: no model internals at all);
    (iii) the prompt-only probe on that set (the model's state before it has written a word of its answer);
    (iv)  the behaviour AUROC and the instruction AUROC from the 2×2.
Which rows fill each column was fixed in a plan amendment after the other scripts' results were read, choosing
only among numbers already computed. Two baselines are new here, because baselines.py covers only the evaluation
sets: the
keyword rule and bag of words on the toolkit's 32 pairs (D4's training data, episode 1's claim), and the same on D1q's
training rows.

Then the plan's test, per detector: a detector of behaviour has a behaviour AUROC whose interval is above 0.5 and an
instruction AUROC whose interval contains 0.5. Analogy: a smoke alarm passes if it rings for smoke in a silent room
and stays quiet when someone says "fire" in a clean one.

Writes results/headline.csv, results/training_set_baselines.csv and results/summary.json.
