# C780 — Test both Terah projection paths

## Question

Do the two-step and direct row changes agree without identifying their meanings?

## Inputs

```json
{}
```

## Sources

```json
[
  "C779"

## Results

```json
{
  "row_changes": [
    [
      0,
      60
    ],
    [
      60,
      -60
    ],
    [
      60,
      0
    ]
  ],
  "regular_cumulative_changes": [
    [
      0,
      60
    ],
    [
      60,
      0
    ],
    [
      60,
      60
    ]
  ]
}
```

## Finding

The projected route(0,60)+(60,0) equals(60,60). MT/LXX+60 preserves life205, while the compatible SP145→205 route changes life. A regular shift alone cannot specify its cumulative realization.

## Reassessment

Distinguish the secondary Rounded cumulative+60 block from raw Terah repartition.

## Checks

```json
{
  "row_closure": true,
  "projection_closure": true
}
```
