# C1468 — State the reconstruction contract

## Question

What must remain attached to a spine so that its relations are reproducible?

## Sources

```json
[
  "Six source objects",
  "Partition law",
  "Anchor and Key comparisons"
]
```

## Results

```json
{
  "state_fields": [
    "manuscript",
    "Regular/Cumulative mode",
    "source frame",
    "Creation/Fall head",
    "named partition",
    "held anchor",
    "operation order"
  ],
  "algorithm": [
    "Read original coordinates in the selected source frame",
    "Form either Flood-only, Noah/Shem-only or both-node source intervals",
    "Reverse each original interval once with trailing-zero places retained",
    "Sum outward from the held anchor",
    "Add the declared original1400 leg only when constructing the completed path",
    "Apply any Key about its expressly named anchor to its declared object"
  ],
  "sufficient_inputs": {
    "source_pairs": 6,
    "named_offset": 600,
    "later_anchors": [
      1406,
      6
    ]
  },
  "failure_conditions": [
    "Erasing the partition changes some outputs",
    "Uniform manuscript translation fails across modes",
    "A head Key is not a complete node map"
  ]
}
```

## Finding

One operation applied to six source pairs and three named partitions reconstructs all eighteen paths; source identity, partition and anchor are essential inputs.

## Reassessment

Review the independently produced algebra and source controls before drafting the new explanation.

## Checks
