# T_305

[The work as shown](https://peteryuill.art/works/T_305). Every value below comes from vae.db, the master database of the Crucible Year.

## Recorded

- **Date:** 2026.05.14, day 137
- **Size:** 70 × 180 cm
- **Paper:** S3, Tanxi Jing Pi, raw
- **Inks:** MB4, MB5, MB6
- **Phase:** P2 The Switch

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

- **Early storage triage:** SA: save, archive (Peter's early system, since retired)

## Measured · V23 (v23.8)

- **V23 rating:** 5
- **Form:** 2
- **Tonal depth:** 1
- **Layering:** 2.2
- **Composition:** 2
- **Material and surface:** 1.8
- **Ink cover:** 79%
- **Dark share:** 35%
- **Tonal steps:** 2

- **Flaws named by the reads:** water stain 5, other 5, tide line 2

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

- **V7:** 8

From an earlier engine (V7). 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 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_305, tone-stretched]

![T_305, classed by brightness]

79% 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: 0.050 (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

“A quarter-arc study in the manner of R3: legible layered passes and banded arcs, but crowded, blocky in the centre-right, tonally narrow, and with milky patches inside the central grey mass.”

Form · BUILT

Left arcs bend fluently with the brush travel; centre-right passes end in squared, slab-like blocks with stiff, stacked terminations.

WEAKEST Stacked rectangular slab passes, centre-right, blunt and blocky

STRONGEST Large upper arc stroke following the brush's turn

Tonal depth · MODELLED

Arcs carry bristle banding and grain; tonal_steps 2 and modulation 0.0495, just above flat; the mid-grey rectangles read as one even tone.

WEAKEST Centre grey slabs, nearly uniform inside

STRONGEST Banded dry-brush striations through the upper arc

Layering · ORDERED

Several translucent passes: pale under-arc, darker arcs and stepped grey blocks overlapping to the right. The order reads clearly across most of the sheet.

WEAKEST Dense overlaps centre-right become hard to separate

STRONGEST Translucent stepped rectangles overlapping the arcs, centre

Composition · WORKING

The arc sweep gives direction from top-left to the right-hand ends, but ink covers 79% of the sheet; the mass is heavy and the right margin is only partly shaped.

WEAKEST Crowded centre mass; right paper strip leftover

STRONGEST Sweeping arc carrying eye from top to right

Material and surface · FLAWED

Dry-brush edges are well used, but pale milky patches and a curved scrape mark sit inside the central grey mass, visible in colour; crease lines cross the sheet.

WEAKEST Milky cloudy patches inside centre grey slabs

STRONGEST Dry-brush grain at stroke ends, right

FLAWS

## 3 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 3 distinct places, 12 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.

GEOMETRY

## Measured from the 16-bit master.

The previous engine (V22) measured this sheet's master file: 2 principal ink masses traced (cyan), 4 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 17 edge segments, 59% crisp, 24% soft or bloomed, 18% broken.

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. 1 major flaw: applied

RULE 3 Any quality below 0.5

The rating cannot exceed 4. lowest 1.8

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_305","cap_no":1,"read_no":1,"cap_text":"sample 1: T 2->1: tonal_steps=2 (<=2)"}; {"run_id":"T_305","cap_no":2,"read_no":2,"cap_text":"sample 2: T 2->1: tonal_steps=2 (<=2)"}; {"run_id":"T_305","cap_no":3,"read_no":3,"cap_text":"sample 3: T 2->1: tonal_steps=2 (<=2)"}; {"run_id":"T_305","cap_no":4,"read_no":4,"cap_text":"sample 4: T 2->1: tonal_steps=2 (<=2)"}; {"run_id":"T_305","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.

MEAN RUNG 2.00 (2.0 + 2.0 + 2.2 + 2.0 + 1.8) ÷ 5
→

RAW 5.00 1 + 2 × 2.00
→

RATING 5.8 5 + 2.086 × (5.00 − 4.60)
