What

After the model hits the same Artifact error reason several times in a session, it is told not to repeat the call: either make the specific change the error describes, or stop calling Artifact and tell you what happened.

Details
  • Two variants share a common prefix: one pushes for the corrective change, the other ends the attempts and reports back to the user.
  • Triggered by a count of same-reason rejections within one session.
Evidence

Do not send the same call again: either make the specific change the error describes

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