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.
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.
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: 0.034 (under 0.045 reads as flat).
Five reads, agreeing on 4 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
“A layered fan around an arch, in R3's mode but weaker. The layering is ordered and legible, but the dark masses are flat inside. The left slabs and bottom-left block are blunt and crowd the arrangement.”
The arc bands around the central arch are coherent and follow the stroke's travel. The left horizontal bars and the bottom-left block are blunt slabs of ink.
WEAKEST Bottom-left rectangular slab, bulky and blunt
STRONGEST Concentric arch bands following the brush's travel
Four tonal steps and a good range of greys in the outer arcs. The dark-interior modulation of 0.034 is flat, and the central black fan and bottom-left block are uniform inside.
WEAKEST Flat central dark fan and bottom-left block
STRONGEST Translucent grey arc bands with dry-brush grain
Several translucent passes overlap legibly across the fan. Their order is readable, and the stepped overlaps build depth toward the central arch.
WEAKEST Bottom-left block covers the lower passes
STRONGEST Overlapping translucent arc segments around the arch
The radiating arch gives a clear direction into the small white opening. The left bars and the heavy bottom-left block feel added on, and the lower-centre white is leftover.
WEAKEST Heavy bottom-left block crowding the lower edge
STRONGEST Radiating fan drawing the eye into the arch
The ink is controlled, with grain at the band edges. The bottom-left block has small mottled blotches, and the dark fan shows faint crease lines. These are minor at viewing distance.
WEAKEST Mottled blotches inside the bottom-left dark block
STRONGEST Dry-brush grain at the edges of the arc bands
4 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 4 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.
Measured from the 16-bit master.
The previous engine (V22) measured this sheet's master file: 11 principal ink masses traced (cyan), 5 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 45 edge segments, 49% crisp, 49% soft or bloomed, 2% broken.
Tonal depth held at rung 1.
4 steps: not appliedMaterial held at rung 1. Mild waves in the unmounted paper are never a flaw.

lowest 1.4A read that breaks the reply format is discarded.
5 of 5 validV23 rating 6.2.
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.
