Thumbnail skip telemetry and publish warnings exist but fire only behind a thumbnail flag that is off by default.
What
A failed or skipped thumbnail read during artifact publish is recorded as an event, and the reason is passed back to the caller as a publish warning. It fires only when the thumbnail feature flag is on, which it is not by default in this build.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
