I might have read this differently in my previous post.

If you meant where to place tanning development between bleach and
tanning, it's tanning. Also, for photographic purposes, tanning =
crosslinking = hardening. The word tanning is more commonly used when
hardening is achieved as a result of development. This is probably
because oxidized developing agents in the form that can crosslink
gelatin can also polymerize and these make colored insoluble products.
