The illustrative setup
This example uses sample records you may replace safely so the learning loop does not depend on production data.
Constraints to set before building
Define the endpoint, input validation, error response and a reset method before changing the VPS size.
A small application workflow
Run one request path, collect a small log, then reset or rebuild the sample data as part of the exercise.
What the builder reviews
Record the sample-data source, test command, expected result and the point at which a reset is safe.
What this scenario is not
This does not claim a public API, live benchmark or retained customer dataset.
