Gateway/provider glitch: runaway tool-tag repetition loop in reasoning channel

Summary

Via vercel-ai-gateway serving deepseek/deepseek-v4.1-flash with thinking level high, the model sporadically enters a decoding loop while emitting tool-call markup inside the reasoning/thinking channel. After writing a normal <parameter>…</parameter> block it never closes the call, and instead emits a constant 23-byte cycle forever:

Unable to resolve module ./node_modules/expo-router/entry

I needed a zoomable image view in SwiftUI that allows user to pan and zoom the image with useful constraints like:

Error: Only plain objects, and a few built-ins, can be passed to Client Components from Server Components.
Classes or null prototypes are not supported.

// 3D Dom viewer, copy-paste this into your console to visualise the DOM as a stack of solid blocks.
// You can also minify and save it as a bookmarklet (https://www.freecodecamp.org/news/what-are-bookmarklets/)
