-// Paste this into a NEW Scrypted Script (Scripts UI → New). Save + Run.
-// The console output tells us exactly which names the Scrypted-eval
-// sandbox is exposing on this Scrypted/core version, which guides what
-// the real `scrypted-viewport.ts` should reference.
-//
-// `declare const ...: any` lines below exist only to keep the editor's

-// look up whatever the runtime injects (or undefined if it doesn't).
+// Paste into the diagnostic / probe Scrypted script. Save + Run.
+// Tells us which Node/mDNS modules the scriptedEval sandbox lets us
+// require() — drives whether the auto-discovery feature can use a
+// proper library or has to fall back to raw multicast UDP.
