jschoubben 311f7f1fdb gitea: the package team may read code, and its units are reconciled
The builder's first credentialed clone of a private repository answered
'not found': the packages team named only repo.packages in its
units_map, which is exhaustive — so members had no code unit at all, and
gitea hides what a user cannot read. One credential answering npm and
git alike was the whole design of the builder's grant; the team now says
so.

And found teams are patched, not just returned: a team is configuration
the reconcile loop owns, the same as a user's password, so a unit this
code gains reaches the team that already exists rather than only the
next mesh raised from scratch.
