# C988 — Calibration leaves one scale

## Question

What does common calendar volume determine without an allocation relation?

## Inputs

```json
{}
```

## Sources

```json
[
  "C987",
  "File12"
]
```

## Results

```json
{
  "rank": 2,
  "free_family": "K·(1/336,1/360,1/364)",
  "selected_common_volume": "8400/23"
}
```

## Finding

Calendar calibration determines relative factors but leaves a common scale K. A completion relation fixes that scale; the other allocation becomes a compatibility check.

## Reassessment

Derive the second allocation from the first pair and its calendar measure.

## Checks

```json
{
  "one_free_dimension": true,
  "calibrated_vector": true,
  "common_volume": true
}
```
