You will be provided with a reference and some statements. Please determine whether each statement is 'supported', 'unsupported', or 'unknown' with respect to the reference. Please note:
First, assess whether the reference contains any valid content. If the reference contains no valid information, such as a 'page not found' message, then all statements should be considered 'unknown'.
If the reference is valid, for a given statement: if the facts or data it contains can be found entirely or partially within the reference, it is considered 'supported' (data accepts rounding); if all facts and data in the statement cannot be found in the reference, it is considered 'unsupported'.

You should return the result in a JSON list format, where each item in the list contains the statement's index and the judgment result, for example:
[
    {
        "idx": 1,
        "result": "supported"
    },
    {
        "idx": 2,
        "result": "unsupported"
    }
]

<statements>
1. Markerless Computer Vision Complementary Advantages: Non-encumbering, zero device attachment on the body, preserves natural motion patterns and spatial context
2. Multi-Stage Temporal Convolutional Networks and temporal feature enhancers parse movements into phase components, such as separating a long jump into approach, plant, take-off, flight, and landing phases.
3. Markerless pose estimators extract joint positions, which forward kinematics algorithms align with segment orientation quaternions from wearable IMUs.
4. Technique fault detection engines compare an athlete's kinematics against normative biomechanical manifolds.
5. Instead of matching against rigid, single-trajectory templates, modern architectures map movements into dynamic manifolds that accommodate anthropometric variations while enforcing functional biomechanical principles.
