# C1004 — Complete mixed-calendar assignment field

## Question

Does matched calendar measurement preserve volume for every fixed Key assignment?

## Inputs

```json
{
  "source_parts": [
    299,
    161
  ],
  "status": "conditional scalar realization; assignments not automatically chronological routes"
}
```

## Sources

```json
[
  "File60",
  "File12",
  "C988"
]
```

## Results

```json
{
  "field": {
    "path": "model/mixed_calendar_complete_field.json",
    "sha256": "1993eb0c0c6c76278b093d3a22fc54de18eb67c6e7e42c6f39a57be05fdcbdd2",
    "bytes": 2280
  },
  "common_volume": 168000
}
```

## Finding

All nine predetermined assignments preserve168000 when each output carries its matching calendar measure. This is one componentwise identity, not nine independent confirmations.

## Reassessment

Use the source mixedJ/E example to expose what unit labels contribute.

## Checks

```json
{
  "complete_nine": true,
  "all_volumes": true,
  "common": true
}
```
