# C962 — Clipped support does not fix the cap

## Question

What interval of k preserves exactly the source clipped identities?

## Inputs

```json
{}
```

## Sources

```json
[
  "C953",
  "C954",
  "C956"
]
```

## Results

```json
{
  "row_thresholds": [
    224,
    336,
    434,
    529,
    584,
    716,
    181,
    850,
    725
  ],
  "support_interval": {
    "lower_inclusive": 584,
    "upper_exclusive": 716
  }
}
```

## Finding

Knowing only which three rows are strictly clipped allows584≤k<716. Exact source lives, not support alone, select601. This interval is a sensitivity result, not a statistical search.

## Reassessment

Test what the aggregate lifespan sum can identify within that support interval.

## Checks

```json
{
  "bounds": true,
  "source_inside": true
}
```
