Technical patterns, industry perspectives, and research from the team building deterministic decision authority for consequential execution.

Why semantic similarity alone is not sufficient for production retrieval, and how a decision layer transforms RAG from a search problem into a decision problem.
In regulated healthcare environments, probabilistic outputs are not enough. How deterministic decision authority meets the bar for clinical decision support.
Evaluation scores model outputs after the fact. Governance enforces decisions before actions reach production. Why the distinction matters for enterprise AI.
The gap between pilot success and production reliability is not intelligence. It is authority. A breakdown of the five most common production failure modes.
When should autonomous behavior be deterministic and when can it be probabilistic? A framework for deciding where the decision plane belongs in your architecture.
How shadow mode lets you validate new rules against real production traffic without executing them. See what would have happened before you turn anything on.
Case Studies
Illustrative examples of how deterministic decision authority applies to real-world autonomous workflows.
Problem: A multi-step deal placement workflow produced inconsistent lender recommendations, with no way to trace why specific lenders were selected or excluded.
Approach: Memrail evaluated each step of the pipeline against business rules - filtering, weighting, fatigue management, and final recommendation - with decision traces at every checkpoint.
Results: Full decision reconstruction in seconds. Wrong decisions resolved before reaching production. Safe iteration via shadow mode before production deployment.
See the solution patternProblem: A clinical decision support agent could not guarantee escalation for high-risk patient states, and effective intervention strategies were lost between sessions due to LLM drift.
Approach: Deterministic escalation pathways, intervention eligibility rules, and context directives ensured the agent always acted within clinical policy boundaries.
Results: Guaranteed escalation for every high-risk state. FDA-grade traceability for every decision. Shadow mode validation before clinical deployment.
See the solution patternProblem: A knowledge advisory platform returned semantically similar content regardless of user context, source appropriateness, or whether the same sources had been surfaced repeatedly.
Approach: Pre-retrieval routing and post-retrieval filtering governed what content was appropriate to surface, with source fatigue management and persona-based eligibility rules.
Results: Content surfacing driven by policy, not just similarity. Explainable retrieval decisions. Source fatigue eliminated through cooldown rules.
