Stable delivery URLs

A ready variant returns an absolute URL shaped like:

https://images.steamcall.com/d/dlv_<binding>/v2/i/img_<image>/r1/128.avif

Use the exact returned URL. Do not construct or replace binding identifiers, append API keys, add arbitrary transformations, or assume an unready path exists. The binding namespace belongs to a Customer and Project; the media identity and recipe identify immutable bytes.

Ordinary Credential rotation preserves saved URLs. Binding rotation creates a new namespace with an explicit overlap deadline. Disabling or retiring a binding, losing commercial access, or disabling its workload can make its saved URLs unavailable. A new binding cannot repair the old namespace.

Stable means the published identity is not silently rewritten. It does not promise perpetual public access. Do not delete published variants merely because they are inactive or a subscription ends. Rights takedown or explicit withdrawal can remove availability separately from access revocation.
