# C860 — Recover the complete 78-row display

## Question

Does one civil index reconstruct every opening and closing boundary?

## Inputs

```json
{
  "civil": "BC b maps to 1−b; AD a maps to a"
}
```

## Sources

```json
[
  "File43 §3.4"
]
```

## Opened utc

## Results

```json
{
  "display": {
    "path": "model/NT_full_display.json",
    "sha256": "d2f7053688c4b16b3671bcf84e6ce0539652095cacaa7b13561b40df7527f591",
    "bytes": 8304
  },
  "primary_span": 5390,
  "extended_span": 5460,
  "crossing_row": {
    "r": 0,
    "open": -5,
    "close": 65,
    "Luke": "Jesus",
    "Matthew": "Jesus Christ"
  }
}
```

## Finding

One rule x(r)=−5−70r reconstructs all 78 displayed rows. The primary 77-row span is 5390; the final AD65–135 extension increases it to 5460.

## Reassessment

Separate named generations, intervals and carrier slots before comparison.

## Checks

```json
{
  "complete": true,
  "consecutive": true,
  "civil_crossing": true
}
```
