# C872 — Freeze the complete operator-domain packet

## Question

Which grids and whole source fields will test the Keys?

## Inputs

```json
{}
```

## Sources

```json
[
  "Strategy §§5C,5E,5F",
  "File12",
  "File46",
  "File51a",
  "File63"
]
```

## Results

```json
{
  "packet": {
    "path": "model/operator_inputs.json",
    "sha256": "fbed103853494c21cb6fa7e37ef4e47e21d9de8d9b4348cea817505001fff8e3",
    "bytes": 22303
  },
  "sources": 7,
  "quarter_rows": 5
}
```

## Finding

The finite test uses integer, Rounded five-year and exact quarter-year grids, the complete File46 head field and the complete File63 multiplier ladder. Formal diagnostic compositions remain distinguished from source-authorized routes.

## Reassessment

Derive the one-Key theorem for any declared lattice.

## Checks

```json
{
  "sources": true,
  "complete_quarter": true
}
```
