 Hey @dugwood, Welcome to Trac, and thanks for bringing this up.

 == Reproduction Report
 === Description
 This report validates that the issue can be reproduced.

 === Environment
 - WordPress: 6.7.1
 - PHP: 8.2.25
 - Server: nginx/1.27.2
 - Database: mysqli (Server: 8.0.40 / Client: mysqlnd 8.2.25)
 - Browser: Chrome 131.0.0.0
 - OS: macOS
 - Theme: Twenty Twenty-Five 1.0


 === Actual Results
 A fatal occurs because `wp_cache_get()` is undefined, as `cache.php` is
 not loaded during maintenance mode.

 {{{

 }}}

 === Additional Notes

 This issue occurs specifically during WordPress maintenance mode (e.g.,
 during upgrades)
