Most cache misconfiguration is not carelessness, it's a missing handshake.

The build encodes assumptions. Hashed filenames mean the URL changes whenever the content changes. The web server has to know that, or the assumption stays unused.

If the config doesn't reflect what the build produces, the framework's work gets quietly undone at the last layer of the chain.
