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](https://peteryuill.art/method). 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. ![T_381] ![T_381, tone-stretched] ![T_381, classed by brightness] 82% of the sheet carries ink TONAL STEPS ## 2 families of tone. Every inked pixel's brightness in 64 bins, smoothed; each circled peak holds at least 4% of the ink. Two or fewer: Tonal depth is held at the bottom rung whatever the model reads. A dense sheet of many translucent passes can count low here, so Layering is left to the reads. Life inside the black: 0.047 (under 0.045 reads as flat). FIVE READS ## Five reads, one answer. Each quality placed on its ladder by each read, and the mean the engine keeps.

The fluent, layered upper fan is offset by a dense, near-flat lower mass. The sheet is ordinary overall.” Form · BUILT Upper arcs follow the brush's rotation cleanly, with crisp stepped ends. The lower half swells into a heavy slab where the separate strokes are lost. WEAKEST Bulky, undifferentiated lower dark mass STRONGEST Fanned arc strokes in the upper head Tonal depth · MODELLED Dark interior modulation of 0.047 is barely above flat, with only 2 tonal steps. The upper fan shows graded bands, but the lower mass reads as one dense dark. WEAKEST Lower-left dark mass, nearly flat in colour view STRONGEST Graded translucent arcs at top and right edge Layering · LEGIBLE Many overlapping arcs stay readable at the top and right edges. In the lower body the passes build up into a single dark where their order is lost. WEAKEST Stacked passes fused in the lower mass STRONGEST Overlapping translucent arcs on upper right Composition · WORKING The vertical S-movement and the two cut-in white notches give the sheet direction. The heavy lower half fills the frame, so the empty paper is only edge leftovers. WEAKEST Crowded, heavy bottom half with little paper STRONGEST S-curve rising through the two white notches Material and surface · SOUND The ink is controlled, with clean arc edges. Faint crease and wrinkle lines cross the dark mass, there are scattered drops at top right, and the paper has a beige tint. None disrupts a principal form. WEAKEST Crease lines crossing the central dark mass STRONGEST Dry-brush stepped edges of the upper arcs FLAWS ## 5 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 5 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. RULE 1 Two tonal steps or fewer Tonal depth held at rung 1. 2 steps: applied RULE 2 A major flaw Material held at rung 1. Mild waves in the unmounted paper are never a flaw. none named RULE 3 Any quality below 0.5 The rating cannot exceed 4. lowest 2.0 RULE 4 At least two valid reads A read that breaks the reply format is discarded. 5 of 5 valid Caps the code applied: {"run_id":"T_381","cap_no":1,"read_no":1,"cap_text":"sample 1: T 2->1: tonal_steps=2 (<=2)"}; {"run_id":"T_381","cap_no":2,"read_no":2,"cap_text":"sample 2: T 2->1: tonal_steps=2 (<=2)"}; {"run_id":"T_381","cap_no":3,"read_no":3,"cap_text":"sample 3: T 2->1: tonal_steps=2 (<=2)"}; {"run_id":"T_381","cap_no":4,"read_no":4,"cap_text":"sample 4: T 2->1: tonal_steps=2 (<=2)"}; {"run_id":"T_381","cap_no":5,"read_no":5,"cap_text":"sample 5: T 2->1: tonal_steps=2 (<=2)"}. 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.
