We Cancelled a 45-Minute Architecture Review. A KCP Query Answered It in 1.2 Seconds.

Last week someone asked the question that usually triggers a meeting: "If we change the payment service API contract, what else breaks?" In any enterprise system older than a few years, nobody has the full picture. The payment service team knows their side. The downstream consumers know theirs. The platform team knows the deployment topology. But the blast radius of a contract change lives in the intersection of what three or four people carry in their heads, and the only way to assemble that intersection has always been to put those people in a room.
We didn't put them in a room. We ran a query.
