You are trying to time-travel to something before the introduction of
time-travel. Hence the unexpected behaviour, I guess.
Thanks for reporting that something is missing. The inferior should
stop and error out. It does not because ’cached-channel-instance’ is
currently called with the argument ’#:validate-channels’ set to the
default (const #t).
Currently, the verification is only done in
guix/scripts/time-machine.scm. Well, this issue seems being part of
bug#65788 [1].
