# C588 — Reject a universal affine carrier conversion

## Question

Can a role-preserving affine map send a70 Enoch cell to72 while keeping its110 rail?

## Inputs

```json
{
  "rail_before_after": [
    110,
    110
  ],
  "local_before_after": [
    70,
    72
  ]
}
```

## Sources

```json
[
  "File69 Appendix B.1–B.4; C587"
]
```

## Results

```json
{
  "required_rail_slope": 1,
  "required_local_slope": "36/35",
  "chronological_gap_patterns": [
    [
      70,
      40,
      70
    ],
    [
      72,
      38,
      72
    ]
  ]
}
```

## Finding

A single role-preserving affine map is impossible: the110 rail forces slope1, while70→72 requires36/35. The source rule changes one carrier parameter while retaining another; it cannot be replaced by global date scaling.

## Reassessment

Determine the ordinary-to-generation transformation within each schematic.

## Checks

```json
{
  "contradiction": true,
  "gap_totals": true
}
```
