        core request, audit, plan, workflow, execution and connector surfaces.


        It is one of THREE error SHAPES this document describes. See

        `CodedErrorResponse` and `TripletErrorResponse` for the other two, and

        the note on `components.responses` for why there is more than one.

        `LLMProviderAPIError` is a code-constrained refinement of the coded

        shape, not a fourth shape.


        This paragraph said "TWO" until issue #3941. `TripletErrorResponse` was

        added by the #3901 reconciliation and this sentence was not updated with

        it, so the document undercounted its own families — which is the same

        defect one level up as the operations that named the wrong one.
