Layer01
Languages and frameworks
Typed end to end where the language allows it. TypeScript on the web, Python where the models are.

Layer02
Models and retrieval
Retrieval pipelines, agent workflows and the prompt plumbing between a model and the data it should answer from.

Layer03
Services and APIs
Boundaries that hold when one part of the product grows faster than the rest.
11
Layer04
Data and storage
Relational schemas designed once and queried millions of times, with the indexes to match.
10
Layer05
Infrastructure and delivery
Releases that repeat without a person watching, and pages measured in the field.
