Can you rebuild the first-request story?

Attempt first

1. A teammate says Spring Boot is “just a faster way to make controllers.” Correct that claim in two sentences, naming the responsibility it takes off your team and one responsibility it does not.
2. Put validation, a business rule, and database access into their likely layers. What coupling appears if the controller owns all three?
3. Predict the complete trip of GET /tasks/42 from a client typing the URL to the response body. Where would a wrong port fail differently from a wrong path?
4. A new endpoint returns 404 although the application starts. List the first three checks, in order, that distinguish a mapping error from a request error.
5. Transfer the model: why is injecting a service into a controller easier to change than constructing it with new?

Completion evidence

Write your request path from memory, then run one endpoint and annotate the actual status code and response. Mark Applied only after you can explain one mismatch you found.
