# C979 — Support after rounding

## Question

Does this particular rounded field keep exactly the three clipped rows?

## Inputs

```json
{}
```

## Sources

```json
[
  "C978"
]
```

## Opened utc

2026-09-28T03:50:42.089004+00:00

## Results

```json
{
  "rounded_active_indices": [
    5,
    7,
    8
  ],
  "ties": []
}
```

## Finding

This source field retains the same three strictly clipped rows and introduces no threshold ties. That is a property of these values, not a universal preservation theorem.

## Reassessment

Compare rounding counts with rounding date labels first.

## Checks

```json
{
  "same_support": true,
  "no_ties": true
}
```
