Vesuvius finite-thickness fusion pilot

This is the preregistered eight-cell handoff requested by Jinho Jeong in ScrollPrize/villa issue #191. It is designed to measure whether a frozen Vesuvius surface checkpoint keeps neighbouring finite-thickness sheets separated as their true air gap closes.

Fixed design

• —painter: `2c483dd`
• —checkpoint: scrollprize/surface_recto_059_redo, Model_epoch499.pth
• —papyrus level 90; noise sigma 6
• —fixed 150 µm sheets; 30 µm voxels; 12 columns; 8 mm Z window
• —pitches 300, 250, 200, and 160 µm
• —independent generation seeds 0 and 1
• —frozen 192³ tiled inference at 50% step, no test-time augmentation

Each NPZ contains exactly three arrays in ZYX order:

The preregistered downstream readout is fusion rate over neighbour-sheet sites and false-split rate over single-sheet controls at thresholds 0.4, 0.5, and 0.6. Recall and near-sheet AUC in manifest.json are secondary descriptive metrics, not the primary endpoint.

Integrity

manifest.json pins the painter, Villa revision, inference harness, checkpoint, generated input volumes, output arrays, and NPZ files by SHA-256. Its SHA-256 is:

The local independent validator reported ALL CHECKS PASSED: 156.

Scope

These are analytic synthetic volumes with exact instance labels. They support a controlled fusion-versus-gap measurement; they do not estimate accuracy on real scroll data and do not establish that any predicted sheet is scientifically correct.
