DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.
Artifacts always record their publish context now, not only behind a feature check.

What
Artifact metadata now carries its publish context whenever one exists, rather than only when a feature check passed. The template field is still behind its own check.
Evidence
publish_context
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
