    Type Alias Probe

    Parsed Criteria or Projection key.

    Structural representation of a Projection or Criteria key, decomposing the encoded string form into its target, transform pipeline, and property path components. Projection and constraint probes share a single shape: a decoded probe is read as a binding or as a constraint according to whether isIdentifier accepts its target, which otherwise carries an Operator.

    // Projection: "vendorName=vendor.name"
    { target: "vendorName", pipe: [], path: ["vendor", "name"] }

    // Constraint: ">=year:releaseDate"
    { target: ">=", pipe: ["year"], path: ["releaseDate"] }
    type Probe = {
        target: Identifier | Operator;
        pipe: readonly Transform[];
        path: readonly Identifier[];
    }

    Properties

    target: Identifier | Operator

    Projection binding identifier or constraint operator symbol.

    For projections, the Identifier portion of a Binding: the name before =. For constraints, the constraint Operator prefix.

    pipe: readonly Transform[]

    Transform pipeline.

    Ordered list of Transform names applied to the path-resolved value, in application order (right-to-left in source notation, left-to-right in this array).

    path: readonly Identifier[]

    Property path.

    Ordered list of Identifier steps navigating to the target value within a resource. An empty path denotes an aggregate over the root value.
