The kernel decides the order at boot time. You probably do not have
years of uptime.
It tends to decide on a steady state, but I do for example have systems
with 8 drives in of different kinds and between the Debian 13 installer
and the Debian 13 installed kernel on first boot they re-ordered
themselves completely. Which was fine because Debian these days is
installed to cope with that sort of thing.
The various directories under /dev/disk/by-* will give you various kinds
of stable identifiers.
Red Hat has a pretty good article about stable names for disks [1].
Debian's page is not as good [2].

Thank you!
Reading them should at least get me asking good questions.
