# C1007 — Key constraint and authorization ledger

## Question

Which new conclusions reduce complexity without enlarging the chronology?

## Inputs

```json
{}
```

## Sources

```json
[
  "C984–C1006"
]
```

## Results

```json
{
  "ledger": {
    "path": "model/key_constraint_ledger.json",
    "sha256": "3bd48f32224cc11b72fa175389b1c6625c0a1c26ad6effa31c77c949548410f0",
    "bytes": 854
  }
}
```

## Finding

The Key families fit one compact constraint language, but calendar units, source cuts and pivots remain indispensable. The next useful transfer is to complete count registers and literary grouping.

## Reassessment

Freeze the Esau/Tishri/NT/Toledot source packet before testing reconstruction and information loss.

## Checks

```json
{
  "scope_preserved": true,
  "new_vs_inherited_separate": true
}
```
