What

A session that pins a specific revision used to be refused outright. The revision is now mapped to a branch, defaulting to staging when none is given and warm for the warm branch, and anything else is refused with the offending reference echoed back, cut off at 80 characters.

Evidence

session named a revision the standby does not prefetch

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
