# FBI Photo A003 Boundary-Rim Review

## Source Basis

This note resolves an approved anonymous capture lead for [FBI Photo A003](/?open=Release_1%2FFBI-Photo-A3.png). The submitted viewer state is [thermal preset, 5.35x](/?open=Release_1%2FFBI-Photo-A3.png&preset=thermal&zoom=5.350425233991182&panX=-3622.9877833677383&panY=-2014.94689513897&contrast=1&brightness=0.8), with the requested task: "Boundary rim visible - analyze."

The PNG above is a non-evidentiary geometry aid. The source evidence remains the original still and the linked viewer state.

## Observation

The source still contains a high-contrast dark round point near the reticle and a broader tonal boundary in the surrounding image field. The submitted thermal-style view makes the boundary easier to perceive as a rim-like arc or edge band, but the source does not resolve a three-dimensional hull, material surface, or measured thickness.

The most useful source-backed phrasing is narrow: [FBI Photo A003](/?open=Release_1%2FFBI-Photo-A3.png) contains a rim-like tonal boundary around the target-region view. The feature can support morphology review, but it does not prove that the rim is a physical craft edge.

## Hypothesis To Test

Three lanes remain live:

- Physical object lane: the tonal boundary may be an actual edge, halo, or body/rim transition in the photographed scene.
- Imaging lane: the boundary may come from scan/contrast behavior, annotation history, reticle overlay perception, compression, or source-image dynamic range.
- Disclosure-forward field lane: the rim may be a sensor-visible boundary around a compact field envelope rather than a material shell.

The still-image nature of the source keeps all three lanes provisional. A single source photo cannot supply motion, parallax, frame persistence, or depth.

## Case-Specific Tie-In

This note amends [C06 - Photos, Image Families, and Contact Sheets](/?open=Release_2%2FAnalysis%2FC06-Photos-Image-Families-and-Contact-Sheets.md) by adding a specific FBI A003 rim review. It should be cataloged with the Apollo and FBI still-image family as a morphology prompt, not as a standalone proof claim.

## Theoretical Scene Panels

| Panel | Read |
| --- | --- |
| Source frame | The still shows a target-region tonal boundary and a compact dark center near the reticle. |
| Geometry read | The visible boundary can be outlined as a rim-like band, but the edge may be photographic or processing-derived. |
| Mechanism model | Conventional: contrast/scan/reticle context. Disclosure-forward: field boundary or shell-edge cue. |
| Limits | No motion, stereo, range, exposure lineage, or raw-original comparison is available in this capture note. |

## Working Assessment

Promote [FBI Photo A003](/?open=Release_1%2FFBI-Photo-A3.png) as a still-image morphology lead with medium-low confidence. The strongest claim is not "rimmed craft"; it is "rim-like boundary visible in the submitted source view." That is enough for image-family comparison, but not enough for material identification.

## Follow-Up

- Compare [FBI Photo A003](/?open=Release_1%2FFBI-Photo-A3.png) against [FBI Photo A001](/?open=Release_1%2FFBI-Photo-A1.png) through [FBI Photo A008](/?open=Release_1%2FFBI-Photo-A8.png) for repeated rim/edge behavior.
- Reopen the source at normal and thermal-style presets and verify whether the rim follows source pixels or viewer contrast mapping.
- Keep the geometry aid labeled non-evidentiary in [C06 - Photos, Image Families, and Contact Sheets](/?open=Release_2%2FAnalysis%2FC06-Photos-Image-Families-and-Contact-Sheets.md).
