# C1170 — Include the baseline early-remainder relation

## Question

Does the MT Arphaxad/Shelah constraint reduce the complete family model rather than only a projection?

## Inputs

```json
{}
```

## Sources

```json
[
  "C1160",
  "C1169"
]
```

## Results

```json
{
  "restricted_native_model": {
    "path": "model/postflood_native_with_early_relation.json",
    "sha256": "e2d25c8794d995a9ca16bbcad5b65a9c753686c1ab310eeb5a36c6418897a732",
    "bytes": 427
  },
  "rank": 20
}
```

## Finding

Including the shared MT403 remainder as a relation reduces the declared whole-family dimension from21 to20. The reduction applies to all native outputs coherently; it does not make403 or the remaining baseline ages self-explanatory.

## Reassessment

Test another explicit repeated baseline value and keep its numerical role separate from shared operators.

## Checks

```json
{
  "constraint_holds": true,
  "rank20": true,
  "one_relation": true
}
```
