# C1046 — Retained biological rows complete identification

## Question

Do the source qI=1 and Isaac→Jacob60 remove the residual ambiguity?

## Inputs

```json
{}
```

## Sources

```json
[
  "C1045",
  "File60 §2"
]
```

## Results

```json
{
  "successive_ranks": [
    11,
    12,
    13
  ],
  "held_source_values": {
    "qI": 1,
    "Isaac_to_Jacob": 60
  }
}
```

## Finding

The two retained source rows restore full rank13. The familiar pattern relations therefore leave real explanatory work to the biological and event data.

## Reassessment

Eliminate the common-point variable to separate a generated coordinate from a cycle condition.

## Checks

```json
{
  "rank_closure": true,
  "source_roles_distinct": true
}
```
