# C1394 — Finalize the calendar comparison reference

## Question

Can the shared modeled volume be inspected independently of placement?

## Inputs

```json
{}
```

## Sources

```json
[
  "draft/Calendar_Measure_Reference.md"
]
```

## Opened utc

2026-09-28T06:47:24.327745+00:00

## Results

```json
{
  "reference": {
    "path": "deliverables/490d_Calendar_Measure_Reference_C1431.md",
    "sha256": "e4abfcbef3b9e2009cb9a73423b8d0a3c36c83b0b24ac870ea460e78eea56c97",
    "bytes": 655
  }
}
```

## Finding

The three-Key reference is finalized with exact factors, output year measures and one common modeled volume, while placement remains a separate input.

## Reassessment

Finalize the source-cost and claim-status notes.

## Checks

```json
{
  "all_keys": true,
  "calibration": true
}
```
