# C1594 — Identify the complete shared inverse prefix

## Question

With Flood, Shem and Noah cuts retained, how far does the910 inverse translation extend?

## Sources

```json
[
  "C1558–C1564 source-prefix results",
  "lower_spine_map.json",
  "translation_cut_domain.json"
]

## Results

```json
{
  "paths": {
    "MT": [
      1406,
      4836,
      5436,
      6026
    ],
    "LXX": [

      6936
    ]
  },
  "node_differences": [

  ],
  "upper_original_legs": {
    "MT": 7620,
    "LXX": 7600
  },
  "upper_inverse_legs": {
    "MT": 2670,
    "LXX": 6700
  },
  "fully_cut_head_difference": 4940
}
```

## Finding

The Flood–Shem–Noah inverse prefixes translate by910 after the common Conquest root. The upper Creation legs then contribute4030 more, giving the inherited4940 head gap.

## Reassessment

Use the proven lower-prefix domain for the restoration comparison; do not extend910 to the full inverse trees.
