2988 questions of the kind that actually get asked — in interviews, in architecture review boards, and by the person who has to run the thing at 3 AM. Every answer states the trade-off rather than the slogan, and says when the obvious choice is the wrong one.

A quick-commerce platform's architecture is bounded by things that are not software: store leases, courier supply, road conditions, and the physical time to pick items off a shelf. How should such constraints enter the design?

A retailer's website must show whether an item is available in a nearby store. Store systems are occasionally offline and physical counts drift from recorded counts. How should availability be modelled?

An observability platform lets customers attach arbitrary tags to metrics. One customer adds a tag containing a request identifier. What would you change about the system's constraints, and why is "tell the customer not to do that" an insufficient answer?
