+# rclaude <host> [dir]
+#
+# Remote, durable Claude Code session. Two layers of resilience stacked:
+#
+#   1. tmux on <host> survives transport drops (network, lid close, ssh kill)
+#   2. `claude --continue` resumes the per-directory session from disk after
+#      anything kills the host itself (reboot, crash, OOM)
+#
+# Re-running with the same <host> + <dir> always lands you back where you
+# were: tmux reattaches if alive, claude --continue picks up the conversation
+# from ~/.claude/projects/<encoded-cwd>/ otherwise.
+#
+# Permission mode: --dangerously-skip-permissions is on by default — these
+# are remote sessions on hosts you own. Override with RCLAUDE_PERMS=default
+# (or any other --permission-mode value) if you want prompts back.
+#
+# Usage:
+#   rclaude apricot                          # remote home dir
+#   rclaude apricot ~/Code/@projects/foo     # specific dir
+#   rclaude apricot @proj/lilith             # alias from project-paths.md
+#                                            # works if remote shell expands it
