The monitor ran a resident asyncio task that sampled psutil/nvml every 0.5–2s and pushed the result over ComfyUI's WebSocket — whether or not any panel was open, whether or not the tab was even in the foreground. It is now a plain GET /kaytool/resources that the panel polls at the same adaptive rate while it is visible and the page is in the foreground. A 200ms cache dedupes concurrent tabs and keeps cpu_percent's "since last call" baseline sane. The RemBG loader stopped setting U2NET_HOME. rembg offers no other way to choose its model directory, and mutating the process environment reached every other rembg-based extension in the same ComfyUI. Models now live where rembg puts them by default; the changelog carries the migration note. Event listeners in gululu.js and nodealign.js use arrow functions instead of .bind(this). Together these remove every finding the registry's policy-v0.2 scanner raised against 0.71.0 except the translators' HTTP calls.
