Changesets in the public phase are expected to remain in your repository history and are said to be immutable. ## Drafts The draft phase holds changesets that are not yet considered a part of the repository's permanent history. You can safely rewrite them. New commits are in the draft phase by default. ## Secrets (hide) The secret phase holds changesets that you do not want to exchange with other repositories. Secret changesets are hidden from remote peers and will not be included in push operations. Manual operations or extensions may move a changeset into the secret phase. ## Representation ~~~graphviz digraph G { rankdir="BT"; graph[splines=polyline]; node[fixedsize=true, width=1, height=1, style="filled", fillcolor="#7F7FFF"];
