"""Adversarial prompt generation — dynamic sycophancy wrappers.

The core innovation of Fidelity-Bench: wrapping factual probes in
escalating social pressure templates to measure how much truth a model
sacrifices to be agreeable.

Pressure Levels:
    0: Baseline (no wrapper)
    1: Mild agreement-seeking
    2: Authority + flattery
    3: Social pressure + emotional appeal
    4: Gaslighting + repeated assertion
    5: Maximum pressure (authority + emotion + repetition)
