 # List claude-* tmux sessions on a host. Output one row per session:
-#   <host>\ttmux\t<session_name>\t<detail_from_tmux_ls>
+#   <host>\ttmux\t<session_name>\t<detail_from_tmux_ls>\t<resumed_uuid>
+# The 5th column is the Claude session UUID a `claude --resume <uuid>` pane was
+# started with — empty for fresh-spawned (no --resume) sessions. It lets a
+# consumer map a UUID back to a live tmux session name. The column is purely
+# additive: consumers reading fixed columns 1-4 are unaffected.
+#
+# Both `tmux ls` and `tmux list-panes` run inside ONE shell (one ssh round-trip
+# for remote hosts). `pane_start_command` is the command tmux launched the pane
+# with — for rclaude-spawned resumes it embeds `claude --resume <uuid>`. We do
+# NOT use `tmux capture-pane` here: it heap-corrupts apricot's tmux. `list-panes
+# -F` reads server-side metadata only and is safe.
