Not a port — a way to answer on real hardware the questions that decide what a port looks like, instead of guessing them from documentation. The one that matters is persistence. ScreenTinker's device identity (deviceId, deviceToken, paired, serverUrl) lives in localStorage, and on BrightSign that behaves like sessionStorage: without a durable store every panel re-pairs on every boot and spawns a new device row. The registry is the alternative, so the probe reports whether it resolves and whether either store survives a power cycle. It runs LOCALLY first on purpose. That establishes whether the @brightsign/* modules resolve at all, separately from whether a remotely-served page can reach them — the question that decides between reusing the hosted web player and building a local shim that owns the registry and passes identity to an iframe via postMessage. Without that split a failure is ambiguous: an origin restriction and nodejs_enabled not taking look identical. Once local works, changing one line points it at a hosted copy and the delta is the answer. Also reports the web-platform features the player leans on — service workers and the Cache API for content caching, h264 in <video>, CSS clamp() for the directory-search keyboard — plus model, OS and Chromium version, since Series 4 is pinned to Chromium 87 and would give a misleadingly pessimistic result. SD-card ready: FAT32, both files at the root, empty card. Remote devtools on :2999. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

' It opens the local probe page with Node.js enabled so the @brightsign/* modules are

' Deliberately local-first: the whole point of the probe is to establish the baseline
