Adaptive Linux fan control. Continuously learns your machine in the background — opportunistic probing, per-channel coupling maps, marginal-benefit RLS, confidence-gated PI/predictive blend. Zero-config first boot, browser-only after, single static Go binary. AMD, NVIDIA, motherboard hwmon, IPMI, Corsair AIO. Any distro, any init, amd64 + arm64.

Community-curated hardware fingerprint → fan profile database consumed by the ventd daemon. One YAML file, LF-only, GPL-3.0.
