- `epoch` is the channel's current epoch (`state.channels` carries it). A private
-  channel derives from its own key instead of `community_root`.
+- `epoch` is the **root** epoch for a public channel: its plane is
+  `channel_group_key(community_root, channel, root_epoch)`, so a Refounding moves
+  it along with the root. A private channel passes its own current channel epoch
+  (`state.channels` carries it) and derives from its own key instead of
+  `community_root`.
 - `timer` is `control.community.message_expiration`; pass `None` when it is off.
  The builder attaches the NIP-40 tag and `seal_rumor` mirrors it onto the wrap,
  so relays drop the ciphertext too.
