The RecSys Factory is an LLM-agent platform that addresses the autonomy-determinism-efficiency trilemma in industrial recommender systems. By bounding autonomy to decision points, the platform achieves a balance between autonomy and determinism. The design principle is to deconstruct runtime, capability, and deployment into three separate components:
- Runtime is deconstructed into three host-emitted event sources, eliminating long-running daemons.
- Capability is deconstructed into a 29-file skill ecosystem, with each skill having a pitfall table that confines autonomy to bounded typed decision surfaces.
- Deployment spans three business lines, each with disjoint label semantics, A/B layer topologies, and operator personas. The platform also retains the human at the diagnostic-versus-execution boundary via a human-in-the-loop card protocol.
