Integration work is where hidden assumptions become expensive.
The endpoint may be simple, but the system around it rarely is. There are timing issues, retries, missing data, edge cases, and operational questions that only appear when real users and real workflows touch the software.
The most useful integration code makes those questions visible. It gives names to states. It logs enough context to support the system. It treats validation as product behavior, not only a technical guardrail.
Clarity is not decoration in integration work. It is how the system survives change.
