The laptop model's hardware module and a memory-pressure module for any machine (hq research 027/03, 026/05, to-be 42 phase 3). The predecessor's polling auto-profile and mem-guard user scripts become each module's own Go code launched by the node runtime (ADR 0198): a profile switcher woken by the kernel's power-supply uevents, and a guard that warns on RAM, swap or PSI before systemd-oomd acts, on the desktop over the account's bus and always as an event. supergfxctl and triggerhappy are kept as found (research 027 Q1).
