# C1068 — File52c interface dependency ledger

## Question

Which interface claims are identities, finite-domain constraints or source-support results?

## Inputs

```json
{}
```

## Sources

```json
[
  "C1058–C1067"
]
```

## Results

```json
{
  "ledger": {
    "path": "model/completed_path_interface_ledger.json",
    "sha256": "5fbd42388730d6d43109a71fa4a68049df61de8723981515ea087d9010d4adfa",
    "bytes": 1179
  }
}
```

## Finding

The interfaces explain how decimal, chronological and Key constructions fit without multiplying independent confirmations. Their exact domains and retained source roles are now explicit.

## Reassessment

Assemble a common operation-and-information map across all investigated families.

## Checks

```json
{
  "eight_classifications": true,
  "no_new_target_measure": true
}
```
