Session detection already hands every backend the live session's env: WAYLAND_DISPLAY from a socket scan, XDG_RUNTIME_DIR from the uid, the session bus, XDG_CURRENT_DESKTOP, and Hyprland's instance signature. sway was the exception — SWAYSOCK had to be INHERITED from the login shell, so a systemd --user host that never saw one had no sway IPC at all: no output enumeration, no capture chooser, no wlroots backend (its is_available() keys off that very variable). It is derivable, and by identity rather than guess: sway names its socket sway-ipc.<uid>.<pid>.sock, and detection already knows the compositor PID. Ladder: a valid inherited value, then the exact PID's socket, then the newest one we own (a sway re-exec can leave the name pointing at a PID we didn't see). None on river — the other wlroots desktop ships no sway IPC, and saying so is what stops apply_session_env exporting a SWAYSOCK that points at nothing. Closes the session-env half of design/per-monitor-portal-capture.md §6 for a desktop-login host: nothing has to be exported for the host to find its session.
