## Sources

## Results

```json
{
  "BC_nodes_then_civil_AD65": [

  "group_first_two_units70": 91,
  "interpretation": "LXX refines the first13 Jubilees on the70-year grid; it does not add another Jubilee boundary."
}
```

## Finding

SP11206→LXX5746→MT4836→1406→AD65 has(78+13+49+21)×70. The first two pieces recombine into13 Jubilees; the LXX cut exposes the shared70-year scale.

## Reassessment

Use the common MT4836 node to test a direct transport of the already-established4900 restoration interval.
