Research the Smallest Surface

Learn only enough of an unfamiliar technology to answer the current question, then return to the problem.

Unknowns

The question

What is the smallest investigation that removes this uncertainty?

Do this

Start with the official contract or documentation for the relevant mechanism.
Build one isolated example that exercises the uncertain boundary.
Record the result and the limits of what it proved.

Example

Instead of studying all of Stripe, create one test payment, capture the callback payload, and repeat delivery to see how duplicates behave.
