# T_360

[The work as shown](https://peteryuill.art/works/T_360). Every value below comes from vae.db, the master database of the Crucible Year.

## Recorded

- **Date:** 2026.07.28, day 212
- **Size:** 97 × 180 cm
- **Paper:** S14, Half-Cooked Red Star Mo She 6-Foot Bark Xuan Paper
- **Inks:** MB6, MB7, MB8
- **Phase:** P3 The Floor Rises

- **Shown on the site:** yes (V23 rating of 5.0 or higher)

- **Early storage triage:** SHP: save, has potential (Peter's early system, since retired)

## Measured · V23 (v23.8)

- **V23 rating:** 6.7
- **Form:** 2.25
- **Tonal depth:** 2
- **Layering:** 2.75
- **Composition:** 2
- **Material and surface:** 2
- **Ink cover:** 70%
- **Dark share:** 62%
- **Tonal steps:** 4

- **Flaws named by the reads:** other 6, dead ink 1

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.

## Older engine

- **V10C:** 9

From an earlier engine (V10C). Its scale differs from V23's, so it is only ever compared with other readings by the same engine.

## How the number was made

Read by the Visual Analysis Engine, version 23.8, on 2026.10.06: measured by code, then read 4 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.

70% of the sheet carries ink

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: 0.028 (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

“This concentric spiral is close to R3 in idea and has good translucent layering. But the central black fan is flat and bulky, the bottom right is crowded, and stray drops mark the right paper.”

Form · BUILT

Inner arcs and thin rings follow the brush's curve fluently. The big black fan and the peripheral rectangular blocks are bulky and stamp-like.

WEAKEST Bulky central black fan, slab-like and filled

STRONGEST Thin concentric arcs around the white centre

Tonal depth · MODELLED

Four tonal steps with real greys across the outer rings. The main black fan is flat inside (modulation 0.028); only faint brush grain shows in the stretched view.

WEAKEST Interior of large central black fan

STRONGEST Translucent grey outer blocks with stepped density

Layering · ORDERED

Several translucent passes stack outward in a clear order. The grey blocks stay readable under the black arcs, similar to R3's layered rings.

WEAKEST Bottom-right overlaps get dense and harder to read

STRONGEST Overlapping translucent grey blocks around left periphery

Composition · WORKING

The spiral leads the eye inward and the empty paper at top right is shaped. The bottom-right band jams against the edge and the right edge feels crowded.

WEAKEST Crowded, cropped bottom-right band of blocks

STRONGEST Spiral pull toward the white eye

Material and surface · SOUND

Ink is controlled and the edges are clean. Scattered ink drops sit on the paper at right, away from the principal masses, and faint creases show at left.

WEAKEST Stray drip dots on the right paper

STRONGEST Dry-brush edges on the outer grey blocks

FLAWS

## 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, 7 mentions in all across 4 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.

GEOMETRY

## Measured from the 16-bit master.

The previous engine (V22) measured this sheet's master file: 1 principal ink mass traced (cyan), 4 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 15 edge segments, 80% crisp, 13% soft or bloomed, 7% broken.

RULE 1 Two tonal steps or fewer

Tonal depth held at rung 1. 4 steps: not 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. 4 of 5 valid

THE ARITHMETIC

## V23 rating 6.7.

Engine v23.8, 4 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.

MEAN RUNG 2.20 (2.3 + 2.0 + 2.8 + 2.0 + 2.0) ÷ 5
→

RAW 5.40 1 + 2 × 2.20
→

RATING 6.7 5 + 2.086 × (5.40 − 4.60)
