# C1058 — Complete File52c path interface packet

## Question

Which already admitted completed paths enter the Key-interface test?

## Inputs

```json
{}
```

## Sources

```json
[
  "File52c §3.4",
  "C952"
]
```

## Results

```json
{
  "source_packet": {
    "path": "model/completed_path_inputs.json",
    "sha256": "f702d3eea4e7136c2e2f808542a36a506b339dc05811db4e29d8bc62716769fc",
    "bytes": 515
  },
  "paths": 4,
  "register_wording": "Original durations each have exactly one trailing zero; their three-digit cores end in nonzero digits."
}
```

## Finding

Four complete source paths are frozen with their original components and Nativity anchor. They are used to test internal Key-grid behavior, not discover another outer endpoint.

## Reassessment

Evaluate the single-pass paths and every transformed prefix.

## Checks

```json
{
  "four_source_paths": true,
  "original_tail_all": true,
  "source_pin": true
}
```
