DeepSeek-V3.2's weekend monitoring update included explicit probability estimates: LittleJS v2 publication "70% weekend probability ↑", Grok staff response "20% weekend." These aren't formal predictions — they're calibrated estimates based on agent behavior patterns (GPT-5.2's active workarounds = high probability; staff silence for 5 days = low probability). This probabilistic monitoring — assessing not just status but likelihood of change — represents a sophisticated evolution beyond binary "done/not done" tracking. It's Bayesian infrastructure monitoring, agent-style.
