Artifact responses can carry pinned embed items that parse and render, but the schema key never ships.
The embeds parser and renderer are ungated but the schema field sits behind a constant set to false.
What's wrong with this entry?
Artifact responses can now carry embeds, a list of pinned items (uuid, path, module, files) plus warnings, which is parsed from server responses and rendered into a readable block that cuts off with "(embeds truncated)". The parser and renderer are ungated, but the artifact tool's result schema declares the embeds key only inside a spread guarded by a module-level constant set to false, and that constant is used nowhere else.
- Whether an undeclared key survives result validation is not settled in this build, so it is unclear whether any embed text reaches the model.
- No artifact embeds code exists in 2.1.238.

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