A front that authenticates every push knows who is pushing; the store knows which branch a pushed check-in resolves to. The front sends only the rule -- X-Zit-Protect, a glob list -- and zit serve --fronted refuses the whole round when a check-in would join one of those branches or a tag would move a held check-in in or out of one. Same error card as a content-policy refusal, so a stock fossil client reads it.

Without --fronted the header is ignored and the server is unchanged. Nothing new on the wire or in the repository. Resolution is crosslink's own, through the fast-read image, which maintain keeps warm between connections. A parent not yet held is admitted: it is judged on arrival. Resolver faults fail closed.
