Architecture
Architecture pages answer the question a design review actually asks: not “how does this work” but “what happens when it doesn’t.” Each one covers a single recurring problem — an AI gateway, a RAG pipeline, a model-serving layer — end to end, from requirements through cost.
Required structure
Section titled “Required structure”Every architecture page carries these sections. scripts/lint-content-structure.ts fails CI if
one is missing.
- Problem — what this architecture exists to solve.
- Requirements — the functional and non-functional requirements driving the design.
- Constraints — what’s fixed: budget, latency, compliance, existing infrastructure.
- Request Flow — a single request’s path through every component, with a diagram.
- Failure Modes — what breaks, and what happens when it does.
- Scaling — what changes at 10x and 100x load.
- Security — the attack surface and how it’s closed.
- Trade-offs — what this design gives up, and why that’s acceptable.
- Cost — where the money goes, and the levers to reduce it.
- Observability — what you’d instrument to know this is healthy.
- Production Deployment — rollout, rollback, and operational ownership.
- Interview Questions — the questions this architecture actually answers.

Every one of the thirteen labs has a design review here, and every page here has a running implementation behind it. The Build section documents the same systems from a run-it-and-verify-it angle; these pages take the design-review angle — what the problem actually is, what breaks, and what you would have to defend in a review.
