# Vumarii 2019 upper-diagram geometry audit

## What this records

Raster-geometry catalog for the Vumarii 2019 upper diagram. It deliberately does not identify a constellation, a coordinate projection, a reading order, a bit stream, or plaintext.

## Input

- Source: `archive/gaps/tr1-00-files/vumarii-2019-imgur-7a4FZ6Q.png` (SHA-256 `bfbdd8b5847e8ae87cbfbdb4cb1894e69fd2a40a90894ab4db875d1c410160a4`)
- Crop: x=270..1099, y=147..738; 830 x 592 pixels.
- Threshold: `max(R,G,B) > 60`; retained ink: `29041` pixels.

## Measured geometry

- Eight-connected ink components: `183`; area range `20`-`680` pixels.
- Enclosed black regions: `36`; these include the centres of hollow circles and other closed shapes.
- Compact candidate hollow-circle centres: `36` under the explicit geometric rule in the JSON file.
- Overlay: `_evidence/vumarii-2019-upper-diagram-holes.png` (SHA-256 `b10252e1dc81505ac5de512fcac80929bd91c2104865e2b3e12c791e5163d673`).

## Interpretation boundary

This does **not** identify a constellation or a star map. No signed source selects an astronomical catalogue, projection, orientation, epoch, magnitude rule, or reading order. The extraction prevents future visual comparisons from silently changing the input, but it cannot turn a resemblance into a solve.
