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.

What
If an artifact action arrives with internal approval fields that no completed permission check attached to that call, the action is denied and the permission classifier cannot approve it. The denial message points at hooks or SDK hosts injecting the fields. This check always runs.
Evidence
Artifact consent markers not minted by a completed permission check fail closed
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
