AFAICS in the docs, under the hood, 'load' calls for
'primitive-load', it's a wrapper for it and may take an additional
argument, the "reader" procedure.  It's a subject to play with :-)

Is there the file "generic-environment.scm" with the module
definition "(define-module (generic-environment) ...)" in the
'%load-path' visible within 'code.scm'?

Maybe, different settings wrt '%load-path' and such in some config
files?  Or maybe some additional modules are loaded when the REPL
starts?  Check what '%load-path' and '(module-uses
(current-module))' return in both cases. (Dunno, if
'%load-compiled-path' can affect something in such a case.)
