The original title is "Agent-Ready Commerce, Part 10: The Reference Architecture"

Short summary

Agent-ready commerce requires a unified decision spine that ensures every surface—storefronts, feeds, APIs, and agent interfaces—project the same commercial meaning. The reference architecture organizes logic through ten layers: source systems → commercial truth → eligibility → authority → checkout → generated claims → audit. Implementation as monolith or microservices matters less than maintaining clear semantic boundaries and preventing adapters from creating conflicting product readiness states.

• •Single decision spine prevents drift: all commerce surfaces must project consistent product readiness, policies, and state transitions
• •Ten-layer architecture (facts→eligibility→authority→checkout→audit) with clear ownership eliminates duplicate commercial meaning across channels
• •Semantic boundaries matter more than deployment topology; a monolith with clear domains beats microservices with duplicated rules
