When an architecture blends multiple judgment elements at runtime (model output, tool selection, history reference, prompt context), the post-hoc separability of contributions is foreclosed: failure modes cannot be redirected to the responsible party because no party owns a separable contribution. The gap is intrinsic to the Autonomous Agentic Loop Quadrant, not a maturity problem that better tooling will solve. Note the sense: this is an accountability-for-action gap, disjoint from the credit-for-source sense of attribution in the Authorship Strategy line.

No. The attribution gap concerns accountability for action (who answers for an agent failure); attribution diffusion concerns credit for source (who originated an idea). The two lines are vocabulary siblings with disjoint subject matter.
アーキテクチャが runtime で複数の判断要素 (model 出力、tool 選択、history 参照、prompt context) をブレンドするとき、寄与の事後分離可能性が閉ざされる: 分離可能な寄与を所有する party がいないため、失敗モードを責任ある party に redirect できない。Gap は Autonomous Agentic Loop Quadrant に本質的に内在し、tooling の改善で解消する成熟度問題ではない。注意: これは accountability for action の gap であり、Authorship Strategy ラインの credit for source の意味の attribution とは disjoint である。
