# C781 — Separate the secondary cumulative block translation

## Question

Does the source Rounded cumulative+60 block come from raw MT Terah repartition?

## Inputs

```json
{
  "source_blocks": [
    [
      14011,
      14006
    ],
    [
      14071,
      14066
    ]
  ]
}
```

## Sources

```json
[
  "File51a §23.7; C779–780"
]
```

## Results

```json
{
  "raw_lifespan_change": 0,
  "secondary_block_change": [
    60,
    60
  ],
  "scope": "source-admitted displayed macro block; no unlicensed full-genealogy extension"
}
```

## Finding

Both operations are legitimate in their stated domains, but their outputs differ: raw lifespan-preserving Terah change gives0 cumulative shift; the secondary display block explicitly moves60. Their provenance must accompany the variant name.

## Reassessment

Compare Cainan support across regular and cumulative representations.

## Checks

```json
{
  "different_operations": true
}
```
