# C914 — Build the complete family-to-operation map

## Question

Which part of the common construction changes from family to family?

## Inputs

```json
{}
```

## Sources

```json
[
  "C831 integrated synthesis",
  "C910–913"
]
```

## Results

```json
{
  "map": {
    "path": "model/family_operation_map.json",
    "sha256": "ea3b4f0350e648e927fd3a69be7f503ed2e0e4e8a1b33b015056f4ac3681e517",
    "bytes": 2070
  },
  "families": 9
}
```

## Finding

Nine family rows now connect directly to shared structures, measures and constructions. Their remaining differences are explicit source choices; the map does not require a new universal date transformation.

## Reassessment

Identify the unresolved source choices that deserve future research priority.

## Checks

```json
{
  "nine": true,
  "complete_columns": true
}
```
