# C900 — Integrate the complete carrier network

## Question

Which added information makes the whole carrier family reconstructible?

## Inputs

```json
{}
```

## Sources

```json
[
  "C892–899"
]
```

## Opened utc

2026-09-28T02:53:31.323685+00:00

## Results

```json
{
  "module": {
    "path": "model/carrier_module_summary.json",
    "sha256": "695f2584682366ab20d84fa38c95e1a3cc51b1fed9c4aeb0da838b61b9dccda9",
    "bytes": 649
  }
}
```

## Finding

The complete carrier family requires the source pair and the treatment of internal boundaries. One anchored rule explains the six heads and their changes; retained biographies require an explicitly different interior construction.

## Reassessment

Join interpolation and extrapolation in one reversible endpoint-coordinate description.

## Checks

```json
{
  "retention_named": true,
  "premises": true
}
```
