Hands-on practice

Build the architecture

Open-ended assignments for practicing architectural judgment.

How labs work

Choose the local architecture path or build with your own tools. Nothing is uploaded.

Marking a lab complete records your progress. It isn't a grade.

  1. 01
    decision.md

    State the requirement, chosen pattern, rejected alternatives, and the reason for the tradeoff.

  2. 02
    implementation/

    Keep the smallest working example, configuration, diagram, or synthetic-trace analysis.

  3. 03
    evidence.md

    Record test cases, observed results, failure behavior, limitations, and evidence locations.

  4. 04
    review.md

    Explain what must be deterministic, what may remain model-directed, and where a human is required.

Create a folder for the lab, use fake data, and start with these files. The architecture path doesn't require an API account.
