# C1238 — Separate cycle compatibility from selection of the downstream node

## Question

Does Adam130 alone force the sourceMoses2580 position?

## Inputs

```json
{}
```

## Sources

```json
[
  "C1237",
  "File51a §7A.2"
]
```

## Results

```json
{
  "bridge_dependency": {
    "path": "model/Moses_bridge_dependency.json",
    "sha256": "38c25a7954001979fe0b8819837abdf7f7f785548833206462452b50c89e59cc",
    "bytes": 691
  }
}
```

## Finding

Adam130 links the two specified target lengths but does not independently choose their downstream node. The full source path supplies2580; the bridge then explains its simultaneous430/490 description.

## Reassessment

Trace the post-Flood130|800 partition back through the unrounded source intervals.

## Checks

```json
{
  "bridge130": true,
  "not_sufficient": true,
  "same_p": true
}
```
