It meant main. A phase branch is the board's own, and merging into it
is bookkeeping in the same family as committing a move — so the
absolute in AGENTS.md, and the same claim on the landing page, both
become "never merges into main". Nothing about the human gate changes;
the sentence just stops overstating it.
The rest is the section the runner needs: how a phase is started, why
the branch exists at all, what makes the beat stateless, what green
means and what halts, and who runs it when there are replicas.
