An interactive concept flow for distributed calls can fail halfway through, from its assumptions through the main operation and boundary checks.
trace / request.md
readyIn a distributed system, a caller may lose contact with a process that is still running, or receive no response after the remote side completed its work. A network partition, overloaded queue, crashed process, and slow dependency can look similar from the caller’s vantage point.
Use the stages in order to explain distributed calls can fail halfway through. Each stage makes one assumption visible: what the operation promises, what representation it uses, how state changes, which boundary can invalidate a shortcut, and what evidence confirms the result.
For a worked explanation, continue to the topic article and execution trace.
