Reading context
A short architecture article. The technical reference supports the topic; hypothetical scenarios and assessment proposals are editorial analysis, not accounts of personal implementations.
Original source ↗The architecture decision
An allowed operation may be inappropriate at the current process stage. Review states and transitions alongside route authorization.
Practical application
Editorial proposal: model a critical journey as a state machine. For a hypothetical order, record actions permitted before and after confirmation, including repetition and concurrency.
How to verify
Test out-of-order calls and verify consistent state. Record duplicate-request handling. Consumers should recover from failures without legitimate retries causing duplicate changes or unauthorized business transitions.
