The V23 rating runs from 1 to 9, with 5 the middle of this body of work. It is the engine's reading, and the reference the archive is measured against.

How the number was made

Read by the Visual Analysis Engine, version 23.8, on 2026.10.17: measured by code, then read 5 times by Claude Opus 5.5 against three reference paintings (R1 to R3), each read independent of the others. How the engine works.

WHAT THE CODE SEES

Three views of one sheet.

Left, the photograph. Centre, the tone stretch the model is shown beside it: the darkest 45% of tones spread over the whole range, so flat black, banding and stains show. Right, every pixel as the measuring code classes it: cyan black ink, deep teal translucent grey, stone the palest ink, near black bare paper.

TONAL STEPS

3 families of tone.

Every inked pixel's brightness in 64 bins, smoothed; each circled peak holds at least 4% of the ink. Life inside the black: 0.035 (under 0.045 reads as flat).

READ 1, IN ITS OWN WORDS

“Two fans built like R3's, but heavier and with flat black interiors. The banding shows only at the rims, the sheet is crowded and the surface is sound. The red drops are deliberate colour. An ordinary sheet overall.”

Form · BUILT

Two quarter-arc fans with walls that hold and edges that follow the sweep, but both bodies are bulky filled slabs rather than travelled strokes.

WEAKEST Right fan's dense, slab-like dark body

STRONGEST Left fan's curved inner notch and arc edge

Tonal depth · THIN

Measured dark modulation 0.035 is flat. Tone steps only at the fan rims; the large black interiors read as uniform surface in the colour view.

WEAKEST Flat black interior of right fan

STRONGEST Stepped grey bands at outer arc edges

Layering · LEGIBLE

Two or three passes legible as concentric grey bands at the rims and the grey wash at bottom left; inside, later black simply covers the earlier ones.

WEAKEST Dark core covers earlier passes entirely

STRONGEST Translucent outer grey rings around both fans

Composition · WORKING

Paired fans around a central slit and opening make a clear structure, but 83% coverage leaves the empty paper as cramped margins; the arrangement is static.

WEAKEST Crowded, near-symmetric masses filling the sheet

STRONGEST Narrow vertical gap leading into the central white

Material and surface · SOUND

Ink is controlled, red drops at the bottom are deliberate colour, and the edges are clean; small spatter dots at left and a faintly cloudy wash at bottom left are minor.

WEAKEST Cloudy grey wash at bottom left

STRONGEST Dry-brush grain at right fan's lower edge

FLAWS

3 distinct places, 0 major.

Each read must name every flaw and where it is, in a ninth of the sheet. Here the reads named flaws in 3 distinct places, 10 mentions in all across 5 reads; the number in each ninth is how many times a flaw was named there. Reads agreeing on a place strengthen the evidence for one flaw; they do not multiply it.

RULE 1Two tonal steps or fewer

Tonal depth held at rung 1.

3 steps: not applied
RULE 2A major flaw

Material held at rung 1. Mild waves in the unmounted paper are never a flaw.

none named
RULE 3Any quality below 0.5

The rating cannot exceed 4.

lowest 1.0
RULE 4At least two valid reads

A read that breaks the reply format is discarded.

THE ARITHMETIC

V23 rating 5.0.

Engine v23.8, 5 reads. Fixed arithmetic, the same for every painting; the constants were set on 24 randomly chosen paintings so the median sheet scores 5. The scale is relative to this archive, not to painting in general, and a difference of less than half a point between two paintings is noise.
