MasDrift is a benchmark of 600 benign productivity tasks across eight domains evaluating authorization preservation in multi-agent systems. It compares single-agent, centralized, and decentralized coordination. Centralized hierarchies achieve 93.9-98.6% task completion but 2.7-19.8% unauthorized actions, while peer networks show 85.7-87.0% completion and 0.6-0.8% unauthorized actions. Re-anchoring defenses outperform chain propagation.

Concrete tradeoff data for anyone building multi-agent systems. Centralized coordination finishes more tasks but leaks more authorization. Re-anchoring beats chain propagation as a defense. Measurable MAS design guidance.
