# C1017 — Festival scale and anchor identification

## Question

Which source constraints determine the fitted walk’s scale and placement?

## Inputs

```json
{
  "counts": [
    30,
    29,
    28,
    27,
    26,
    25,
    24,
    10
  ],
  "fixed_landings": {
    "step2": 1446,
    "step7": 536
  }
}
```

## Sources

```json
[
  "File58 festival walk",
  "C1016"
]
```

## Results

```json
{
  "scale": 7,
  "anchor": 1859,
  "all_landings": [
    1859,
    1649,
    1446,
    1250,
    1061,
    879,
    704,
    536,
    466
  ],
  "status": "conditional reconstruction of an already fitted source family"
}
```

## Finding

The two fixed role positions recover scale7 and anchor1859, after which all supplied boundaries follow. This replaces two parameters with two equivalent constraints, not two new predictions.

## Reassessment

Hold those role positions and test a controlled order change.

## Checks

```json
{
  "scale_anchor": true,
  "complete_landings": true
}
```
