Only the selected viewer requests its backend. A sleeping free service may take about a minute to start. Opening this version index does not wake every service or trigger a deployment.
Viewer files are retained with checksums. Remote data, external libraries and live services can still become unavailable. Historical pages preserve their original text; they do not certify current backend availability or promise a service-level agreement.
The stable v0.5.0 local demo is available now. Historical hosted services retain their original versions; separate version-pinned v0.5.0 hosted lanes are not yet advertised. Existing links remain available.
