# Machine Reading V1 — 185 Ticket Scans

> Diagnostic computational output. Not catalogue completion or historical evidence.

- Corpus processed: **185 / 185** published, non-duplicate ticket scans
- Visual clusters selected by silhouette score: **5**
- OCR records returned: **185 / 185**
- Records containing recognised text: **184**
- Mean OCR confidence: **0.523**
- Visually unstable cluster assignments (negative sample silhouette): **34 / 185**

## Protocol boundary

The machine measures image properties, proposes OCR transcriptions and forms temporary visual groups. It does not establish provenance, circulation, authenticity, use, or historical meaning. Every OCR string and cluster assignment remains reviewable.

## Cluster selection diagnostics

- k=4: silhouette 0.1166
- k=5: silhouette 0.1292
- k=6: silhouette 0.1069
- k=7: silhouette 0.1134
- k=8: silhouette 0.1155
- k=9: silhouette 0.1208
- k=10: silhouette 0.1282

The best score is low, so these groups should be treated as inspection aids rather than a stable taxonomy.
