# C1186 — Test head identification after shared-amplitude compression

## Question

Do two chronology heads identify the four-amplitude form?

## Inputs

```json
{}
```

## Sources

}
```

## Finding

Even the four-amplitude form leaves two directions hidden from the heads: the sixty-year allocation and the trade between Lamech’s correction and the paired early increments. Complete fields are needed to locate them.

## Reassessment

Restore native Cainan and distinguish insertion information from coefficient compression.
