# C1608 — Identify the selected700-year grid and its domain

## Question

Does the common refinement admit a compact integer coordinate description, and does the omitted LXX cumulative Flood share it?

## Sources

```json
[
  "three_MSS_12600_path.json",
  "three_cumulative_restoration.json"
]
```

## Results

```json
{
  "gcd_edges": 700,
  "relative_indices": [
    18,
    10,
    7,
    0
  ],
  "ordered_edge_indices": [
    8,
    3,
    7
  ],
  "LXX_cumulative_Flood_remainder700": 210,
  "scope": "selected LXX Regular head/MT-SP cumulative Flood path, not all six spines"
}
```

## Finding

The chosen path has relative indices18,10,7,0 in units700. LXX cumulative Flood8446 has remainder210 on that grid, though it remains on the finer70 grid.

## Reassessment

The700 grid is a property of this named subpath. Derive its5600 edge directly from the inverse source words.

## Checks
