# C1228 — Distinguish common translation from a changed held anchor

## Question

Is equal gain automatic for another comparison anchor?

## Inputs

```json
{}

## Sources

## Results

```json
{
  "anchor_dependence": {
    "path": "model/SP_rectangle_anchor_dependence.json",
    "sha256": "79f6de07f587cb73249f1bc7555e484298cff70ca7200a7c88fb9f3c98ceba84",
    "bytes": 612
  },
  "conditional_anchor": 1446
}
```

## Finding

For these fixed source heads, equal gain selects1446 algebraically. Moving only the comparison anchor breaks the equality; translating the complete frame preserves it. The source’s Exodus identification is separate from the equation.

## Reassessment

Present the entire source-to-rectangle dependency chain with its explanatory limits.

## Checks

```json
{
  "anchor1446": true,
  "law_all": true
}
