**Interpretive Reconstruction — Not Source Evidence.** Viewpoint A visualizes a compact craft partly obscured by one coherent refractive envelope. Its dark lobes are a model for sensor-visible field coupling, not resolved hull fragments.

The source is [PR107 - Unresolved UAP Report, Eastern United States, 2020](/?open=Release_4%2FDOD_111830041.mp4). The primary annotated state is [16.947s](/?open=Release_4%2FDOD_111830041.mp4&t=16.947&preset=normal&zoom=2.4242917482282365&contrast=1.15&brightness=1&centerX=0.44698057359651433&centerY=0.4554885154153804).

This Guide builds on [C92 - PR107 Eastern US 2020 Reticle-Crossing Contrast Sequence](/?open=Release_4%2FAnalysis%2FC92-PR107-Eastern-US-2020-Reticle-Crossing-Contrast-Sequence.md). That report preserves the wider sequence, raw observations, enhancement limits, and the earlier disc/bubble retest. This Guide isolates a narrower interpretive fork: whether the broken silhouette deserves a field-effect test lane rather than being dismissed as a camera defect.

The raw review aids are evidence references. The three photorealistic images in this Guide are reconstructions and must not be used as proof.
