Architecture Blueprint¶
Services β 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.
Trace schema
What gets stored for every decision: path, evidence, rules applied, and the exact reason for answer vs abstain.
Measurement & gates
Operational metrics and validation gates that make reliability measurable: regressions, drift, and policy violations become visible.

π¦ This diagram makes the Blueprint iterative and gated: each layer has a decision point (semantics sufficient? constraints sufficient? evidence replayable? gates + traces complete?). If not, we loop into focused modeling work instead of pretending weβre ready to build.
Why clients like this phase¶
Because it reduces vendor lock-in.
You own the semantics and constraints even when models change.

π This diagram is the anti-lock-in mechanism: you can swap models, but you keep π§© semantics and π constraints stable β so outputs remain β governed and comparable across model churn.
What happens next¶
The Blueprint becomes the build plan for a glass-box implementation: enforceable gates, traces, monitoring, and a team-ready handover.
