# C1027 — Formal closure reveals the missing source permission

## Question

What extra merge would make the section grouping stable under reflection?

## Inputs

```json
{}
```

## Sources

```json
[
  "C1025",
  "C1026"
]
```

## Results

```json
{
  "formal_blocks": [
    [
      1
    ],
    [
      2,
      3
    ],

    ],
    [
      9,
      10
    ],
    [
      11
    ]
  ],
  "extra_merge": [
    "Adam",
    "Noah"
  ],
  "status": "obstruction witness only; source does not authorize the extra merge"
}
```

## Finding

A formal stable closure would merge Adam and Noah as well as the two Esau occurrences. That shows the cost of forcing quotient symmetry; the source sections are retained unchanged.

## Reassessment

State a general descent criterion and test it against a legitimate chronological coarsening.

## Checks

```json
{
  "stable": true,
  "nine_classes": true,
  "extra_merge_required": true
}
```
