Core no longer fills a slot by name - it offers a contribution and the module
that owns the page says where each one goes (MODULE_API 1.6.0, amended). The
three slot names are unchanged and stay this module's own vocabulary; what is
new is the second argument saying which of core's three contributions belongs
in each place.
Nothing here worked differently before. The change is for every game that is
not this one: core used to fill the literal name uo.guild.detail, so a second
module declaring a place under its own id got an empty page and no error.
The registration fake gained the same validation core does, including the
contribution catalogue - written down rather than imported, since this suite
runs against the built chunk with no core in the process, which makes it a
claim about core that has to be re-read when core's list changes.
