# C573 — Connect the two Actual/Rounded interfaces

## Question

Can the endpoint square and weighted bridge coexist without conflating their terminals?

## Inputs

```json
{
  "Creation_regular_Actual": 4114,
  "Creation_cumulative_Actual": 14004,
  "Creation_regular_Rounded": 4106,
  "Creation_cumulative_Rounded": 14006
}
```

## Sources

```json

  "C531 synthesis; File63 §9.7; latest File52c"
]
```

## Results

```json
{
  "weighted_anchors": [
    12026,
    12026
  ],
  "Creation_changes": [
    2,
    -8
  ],
  "weighted_change": 0,
  "interfaces": [
    "Creation/Exodus→Creation/Conquest",
    "Actual/rounded regular+cumulative Creation→12026"
  ]
}
```

## Finding

Both interfaces share the cumulative Creation change14004→14006. The regular Creation change4114→4106 cancels it in the weighted12026 bridge; the terminal change1446→1406 instead contributes to the42-year span gain. The maps meet at a node but do different work.

## Reassessment

Reconstruct the common integral Key lattice across the newly linked spans.

## Checks

```json
{
  "same_anchor": true,
  "cancellation": true
}
```
