+# Plain `ssh ... tmux new-session -d` — mirrors the attached remote path
+# below (just `-d` instead of `-A`). A tmux server already survives ssh
+# disconnect by design (that is what tmux is for); no cgroup gymnastics
+# are needed. An earlier `systemd-run --user --scope --collect` wrapper
+# here was a regression — `--collect` reaped the scope (and the tmux
+# server inside its cgroup) the instant the spawning client exited, so
+# the session never materialized. Verified 2026-05-20: plain ssh+tmux
+# detached spawn survives; the systemd-run variant did not.
 # Mosh is interactive-only — always go through ssh for detached spawn.
