Type Alias ValueExpr

ValueExpr:
    | { type: "literal"; value: unknown }
    | {
        field: string;
        path?: string;
        scope?: "workflow" | "stage";
        type: "fieldRead";
    }
    | { param: string; type: "param" }
    | { type: "actor" }
    | { type: "now" }
    | { type: "self" }
    | { type: "stage" }
    | {
        fields: Record<
            string,
            | { type: "literal"; value: unknown }
            | {
                field: string;
                path?: string;
                scope?: "workflow" | "stage";
                type: "fieldRead";
            }
            | { param: string; type: "param" }
            | { type: "actor" }
            | { type: "now" }
            | { type: "self" }
            | { type: "stage" }
            | ({ type: "object"; fields: Record<string, ValueExprInternal>; }),
        >;
        type: "object";
    }

An operation's write value, resolved when the operation applies. param reads a caller-supplied action argument; actor records the acting identity. now supplies the operation's ISO timestamp, self its instance's GDR URI, and stage the current stage name. object resolves its fields recursively.

A fieldRead with no scope searches activity, stage, then workflow fields. An explicit scope searches only that scope. A pathless read from a subject or doc.ref into another subject or doc.ref preserves the stored reference. Other reads use the referenced snapshot document, or only its _id and _type when it is not loaded. No additional documents are fetched. Initialization uses FieldSource, whose field-read scope rules differ.
