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 2026.10.06: 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

4 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: 0.036 (under 0.045 reads as flat).

FIVE READS

Five reads, agreeing on 3 of 5 qualities.

Each quality placed on its ladder by each read, and the mean the engine keeps. Where reads differ, they differ by one rung; close calls resolve down.

READ 1, IN ITS OWN WORDS

“An arc structure close to R3, with legible stepped passes, but the dark core is flat and heavy. The top-left blocks are stiff, and blots mar the right arc's grey band.”

Form · BUILT

Concentric arcs hold their walls and follow the brush's sweep; top-left blocks are bulky rectangles with stiff, clumsy joins to the main arc.

WEAKEST Slab-like rectangular blocks at top left

STRONGEST Separate right arc, clean curved walls

Tonal depth · MODELLED

Measured dark modulation 0.036 is flat; the central black mass is near-uniform. The outer grey bands and four tonal steps give graded tone around it.

WEAKEST Central black arc mass flat inside

STRONGEST Stepped grey bands at outer arc edges

Layering · ORDERED

Several translucent arc passes overlap in a readable order, especially at the lower-left and outer rim. The dark core hides some of the passes beneath.

WEAKEST Dark core covers earlier passes beneath it

STRONGEST Stepped translucent bands at left and lower arcs

Composition · WORKING

The main arc sweeps strongly and the right arc echoes it. The bottom-left void is shaped, but 82% coverage makes the centre heavy and crowded.

WEAKEST Crowded, heavy dark mass filling centre-right

STRONGEST Right arc echoing the main sweep

Material and surface · FLAWED

A teardrop blot and mottled wash sit inside the right arc's pale band, and drips are scattered at the top right, all visible in colour. Elsewhere the ink is controlled.

WEAKEST Teardrop blot inside right arc's grey band

STRONGEST Dry-brush stepped edges on lower arcs

FLAWS

4 distinct places, 1 major.

Each read must name every flaw and where it is, in a ninth of the sheet. Here the reads named flaws in 4 distinct places, 17 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. A major flaw holds Material and surface at rung 1.

RULE 2A major flaw

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

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.
