2026-07-18 dev-box incident: on a warm relogin (user manager kept alive
by the tty1 greetd session — no linger involved) the previous logout's
graphical-session.target stop had been rejected as a destructive
transaction (easyeffects held a queued start job), so the target stayed
active across the logout. Its WantedBy services (cliphist, swaync,
xdg-desktop-portal-*, swayosd, …) crash-looped against the dead Wayland
socket into start-limit-hit, and the next login's plain
'start hyprland-session.target' was a no-op — every session service
stayed failed, doctor red, until a reboot.
Session bring-up (HM's systemd.extraCommands, rendered into the first
exec-once) now stops both hyprland-session.target and a possibly-stale
graphical-session.target, clears failed/start-limit state with
reset-failed, then starts fresh. All three commands are no-ops after a
clean logout or cold boot.
Verified V1: home generation built against this tree renders the new
command chain into hyprland.conf line 1 (nix build of
homeConfigurations.bernardo with the nomarchy input overridden).
V3 pending: warm relogin on hardware — queued in HARDWARE-QUEUE with
exact steps; BACKLOG #149 updated with the incident evidence (the
exec-once posture it watches is defending against a real race).
