# C1188 — Distinguish insertion from redistribution at the named boundary

## Question

Can the same head change conceal different internal birth paths?

## Inputs

```json
{}
```

## Sources

```json
[
  "C1187",
  "C1167"
]
```

## Results

```json
{
  "witness": {
    "path": "model/insertion_redistribution_witness.json",
    "sha256": "d11e0e5d562cd187b3e4c49bff508fa3f70b2630d3d9df40c68ece1782c086b0",
    "bytes": 495
  },
  "equal_terminal_total": 395
}
```

## Finding

An added130 can be hidden in a neighbouring interval if only the total is observed. The new Cainan-labelled boundary and its incidence recover the structural distinction.

## Reassessment

Summarize the whole-genealogy row grammar before moving to Rounded information loss.

## Checks

```json
{
  "same_terminal": true,
  "different_internal_fields": true,
  "extra_vertex": true
}
