Over 54 million Americans are aged 65+, with depression affecting 25-49% and anxiety exceeding 30% of assisted living residents. AI systems employing agentic orchestration exhibit 0.5-2% failure rates--unacceptable where a single missed crisis can be fatal. We designed and bench-evaluated Lilo Engine, a 5-layer deterministic therapeutic pipeline replacing a prior multi-agent orchestrator. Safety is enforced through structural invariants: a Guardian layer with 4-gate OR crisis detection runs unco...
