Architecture notes.
Not architecture for its own sake. The patterns, boundaries and design decisions that make technology useful, reliable and possible to evolve.
Start with the responsibility.
Then choose the technology.
Architecture is not a collection of boxes or a vendor diagram. These notes explore the decisions underneath: where state lives, who owns a business capability, how systems recover, what must be deterministic and where AI adds real value.
Agent-ready enterprise software.
A conceptual reference model, not a deployed architecture or an assertion that every system needs all three layers.
What matters in practice.
Make boundaries explicit.
Define business capabilities and ownership before debating where the intelligence should run.
Design for failure.
Recoverability, idempotency, observability and transaction controls aren't optional afterthoughts.
Prefer useful autonomy.
Keep judgment where it belongs and make automated execution safe, explainable and auditable.
