# C1229 — Write the Strategy rectangle from the row mechanisms

## Question

Can the larger relation now be explained as one connected construction?

## Inputs

```json
{}
```

## Sources

```json
[
  "C1223–C1228",
  "C1143",
  "C1154"
]
```

## Results

```json
{
  "explanation": {
    "path": "deliverables/Source_Rows_to_SP_Equal_Gain_Rectangle.md",
    "sha256": "26de2697e7a6c74c6b60fff95888ed90aa329d5e386cc19f8a425cf909036285",
    "bytes": 2058
  }
}
```

## Finding

The Strategy rectangle is now a connected source-row, cap, placement and Key construction. Its inherited numerical closure is explained alongside the remaining absolute and node-role premises.

## Reassessment

Review the second block’s net explanatory gain and choose the next complete source family.

## Checks

  "all_stages": true,
  "source_limits": true,
  "no_new_count": true
}
