Architecture Blueprint¶
Services → design
Turn domain knowledge into a system you can own.
The Blueprint phase converts scattered expertise into durable semantics, enforceable constraints, and a reference architecture. The goal is straightforward: make reliability a property of the system, not a hope inside prompts.
Outputs
Domain model
Concepts + relations that describe what exists, what happens, and what matters in decisions.
Constraint model
Rules the system must enforce: what must never happen, what must be proven, what must be escalated.
Ingestion strategy
How facts and sources enter: provenance, versioning, extraction methods, and validation gates.
Reference architecture
Components and responsibilities: retrieval, traversal, constraint gate, trace store, evaluation, monitoring.

Because it reduces vendor lock-in.
You own the semantics and constraints even when models change.

The Blueprint becomes the build plan for a glass-box implementation: enforceable gates, traces, monitoring, and a team-ready handover.
