# C1022 — NT placement as an alternative basis

## Question

Can the two supplied co-registrations recover both hinge and unit?

## Inputs

```json
{
  "slot_indices": [
    55,
    20
  ],
  "BC_coordinates": [
    3856,
    1406
  ]
}
```

## Sources

```json
[
  "File54",
  "C1021"
]
```

## Results

```json
{
  "determinant": -35,
  "hinge_and_unit": [
    6,
    70
  ],
  "ceiling": "already constructed source co-registrations; consistency basis, not independent origin proof"
}
```

## Finding

The co-registrations recover the6BC hinge and70-year unit. Since those positions belong to the existing schematic display, this is an equivalent parameterization, not a new historical derivation or Nativity revision.

## Reassessment

Test how Toledot grouping changes the measured object itself.

## Checks

```json
{
  "unique": true,
  "source_basis": true
}
```
