Healthy is an import-time observation
During a catalog import, AdiosTV records whether an HTTPS address responded and whether the HLS manifest could be inspected from the import environment. The displayed timestamp belongs to that snapshot. There is no continuous multi-region monitoring in the current public product.
Degraded is useful, not vague
Degraded can mean a partial response, timeout or another import-time warning. Specific labels such as CORS blocked, mixed content, geo-blocked, unsupported codec and DRM explain why an otherwise reachable source may still be unsuitable for a browser session.
Your result can differ
An import check cannot reproduce every network, device or region, and public links can change after the snapshot is created. If your result differs, use the browser error shown by the player and never publish a signed URL, token or account credential.
