# C934 — Replace six dates by a reversible path-coordinate packet

## Question

Which numeric coordinates retain the entire paired source construction?

## Inputs

```json
{}
```

## Sources

```json
[
  "C933"
]
```

## Results

```json
{
  "path_coordinates": {
    "path": "model/junction_path_coordinates.json",
    "sha256": "29fbe2ce30c47b217936b1ca1fbaf3003a76af26a370fb7a46506be8848bfee8",
    "bytes": 395
  },
  "coordinates": {
    "anchor": 1406,
    "tail": 1400,
    "regular_legs": [
      1650,
      1050
    ],
    "cumulative_legs": [
      9170,
      3430
    ]
  }
}
```

## Finding

One shared anchor, four ordered legs and one tail exactly retain all six source dates. This is a change of coordinates, so it compresses notation but does not itself explain the source values.

## Reassessment

Remove common translation and identify which junction claims depend only on durations.

## Checks

```json
{
  "recovery": true,
  "six_coordinates": true
}
```
