## Results

```json
{
  "next_question": "Use existingpost-Flood rowreconstructions to explain the cumulativeMT–LXX910 translation at its source positions, then join itsShem/Flood–Exodus/Babylon path to the presentinverse graph.",
  "held_rules": [
    "currentnativeLXX inputs",
    "acceptedSPFall",
    "currentKeyanchors",
    "singledecimalreversal"
  ],
  "purpose": "compress source-generation andcross-familyplacement together",
  "not_new_holdout": "existingsourcefamily; reuse andclarification"
}
```

## Finding

The next useful synthesis is the source anatomy of the910-year MT–LXX cumulative translation, using existing row reconstructions rather than reopening theinverse rules.

## Reassessment

Finish the readable-record checks, then reread thefullStrategy atC1582.
