Force N contrarian critique points against a target position. Each point carries a severity tag (BLOCKER / HIGH / MEDIUM / LOW) and a committed paragraph attacking from a distinct angle. Target is either inline (/devil 5: <claim>) or walked back to the latest substantive decision/claim in conversation. Manual sycophancy-breaker. Cheap alternative to /council (external) and /scrutinize (multi-phase). Single-shot per invocation. Default N=5, valid range 1-10. Honesty floor: stops early rather than fabricate weak points to hit N.
