PL-004 — Intelligence Platform

Status: Canonical
Owner: Intelligence Platform
Repository: zaixos-intelligence-platform
Last updated: 2026-07-05

---

Purpose

Learning and intelligence layer — version registry, recommendations, optimization, and enterprise intelligence services. Separated from runtime execution so learning never couples to live agent paths.

---

Responsibilities

Owns

Service	Role
EnterpriseVersionRegistryService	Canonical prompt/model/version records
RecommendationRegistryService	Recommendation lifecycle
Learning / optimization engines	Offline improvement loops
Intelligence signals processing	Feeds planners indirectly via registry

Does not own

• Live agent turn execution (PL-003)
• Product presentation (PRD-xxx)
• Benchmark execution infrastructure (PL-006 instruments)

Why PL-004 owns learning

Products and runtime must not embed learning logic — it creates untestable coupling and bypasses closed-loop governance.

See ADR/ADR-010-why-pl-004-owns-learning.md.

---

Contracts

Intelligence platform contracts consumed via product Integration adapters — never direct engine imports outside Integration module.

---

Known limitations

• Some subsystems use in-memory persistence (grandfathered — see certification reports)
• Registry registration pending full A0 in zaixos-registry
