 ## Channel

+- Harness-native cross-session messaging (Claude Code's SendMessage and
+  ListAgents, or any equivalent built into a harness) is not a Mosaic
+  channel. Jason, 2026-09-12: Mosaic Stack develops and uses its own

 - `tools/tmux/agent-send.sh` is the only send path. It prepends the preamble,
  submits reliably (bracketed paste, Enter flush, draft detection), and ships
  itself over ssh for remote targets. Never raw `tmux send-keys`; that is how
