# C841 — Resolve all shared boundaries of the two festival orders

## Question

Which overlaps follow from the complete prefix sets?

## Inputs

```json
{}
```

## Sources

```json
[
  "C839–840"

## Results

```json
{
  "shared_boundaries": [
    {
      "count": 0,
      "years": 0,
      "BC": 1859,
      "forward_step": 0,
      "reverse_step": 0
    },
    {
      "count": 59,
      "years": 413,
      "BC": 1446,
      "forward_step": 2,
      "reverse_step": 3
    },
    {
      "count": 140,
      "years": 980,
      "BC": 879,
      "forward_step": 5,
      "reverse_step": 6
    },
    {
      "count": 199,
      "years": 1393,
      "BC": 466,
      "forward_step": 8,
      "reverse_step": 8
    }
  ],
  "status": "complete dependent comparison of the two declared orders; no alternative-order search"
}
```

## Finding

The two paths share only counts0,59,140,199, producing1859,1446,879,466. Their common internal boundaries occur at different step indices, so endpoint agreement does not identify the ordered paths.

## Reassessment

Test scaling and order as separate linear operations.

## Checks

```json
{
  "exact_set": true,
  "internal_indices_differ": true
}
```
