# C1385 — Prepare the final primitive-data register

## Question

Can supplied and derived input roles be understood without reading the notebook?

## Inputs

```json
{}
```

## Sources

```json
[
  "deliverables/Primitive_Data_Register_C1293.json",
  "draft/Source_Cost_Summary.md"
]
```

## Results

```json
{
  "register": {
    "path": "deliverables/490d_Primitive_Data_Register_C1431.json",
    "sha256": "835256a979ce3144314519cf922937bb630f0fe3c37d1bf7cda923d31bf2151c",
    "bytes": 55533
  },
  "modules": 8
}
```

## Finding

The final primitive register retains all eight bound source modules and adds plain-language guidance about derived summaries and retained information.

## Reassessment

Prepare the final operation inventory.

## Checks

```json
{
  "eight": true,
  "module_hashes": true
}
```
