    Interface ErrorEvent

    A recorder threw in a scope-channel hook (operation says which kind: a read, a write, or a commit hook). Delivered to every recorder on the scope channel, inline and deferred alike (recorder/hooks.ts · recorderFailureEvent).

    interface ErrorEvent {
        channel?: "scope";
        correlation?: RunCorrelation;
        error: StructuredErrorInfo;
        key?: string;
        operation: "commit" | "read" | "write";
        pipelineId: string;
        runtimeStageId: string;
        stageId: string;
        stageName: string;
        timestamp: number;
    }

    channel? correlation? error key? operation pipelineId runtimeStageId stageId stageName timestamp
    channel?: "scope"

    Explicit channel discriminant — 'scope' on every engine-dispatched event. isFlowEvent() checks it first (backlog B3); optional so consumer-fabricated events (tests, replays) remain type-valid and fall back to the legacy pipelineId-presence heuristic.

    correlation?: RunCorrelation

    The run's correlation (10.1) — the same frozen object as TraversalContext.correlation on the flow events and getSnapshot().correlation. Absent — no key — when the run's env gave none.

    error: StructuredErrorInfo

    What the recorder threw, in the structured form (9.39.0): message and name read as before; raw is the thrown value itself (an Error, a string, anything). One shape on every path — until 9.38.0 the inline paths passed the raw thrown value and the deferred tier a new Error(...).

    key?: string
    operation: "commit" | "read" | "write"
    pipelineId: string
    runtimeStageId: string

    Unique per-execution-step identifier. Format: [subflowPath/]stageId#executionIndex

    stageId: string

    Stable stage identifier (matches spec node id).

    stageName: string
    timestamp: number
