# C852 — Reconstruct all existing paired-anchor endpoints

## Question

Does a single digit-register operation recover every original File52c endpoint?

## Inputs

```json
{}
```

## Sources

```json
[
  "model/inverse_inputs.json; latest File52c existing manifest"
]
```

## Results

```json
{
  "field": {
    "path": "model/inverse_paired_field.json",
    "sha256": "eea45a0802d05e2ada4ee33ae2685da893929e1995083b0df2ebcfa2f86f2ce9",
    "bytes": 19047
  },
  "source_rows": 32,
  "existing_endpoints": 64,
  "scope": "original durations only; no target enumeration"
}
```

## Finding

Every existing endpoint is reproduced by one digit-position evaluation with its original zero-placeholders. The whole paired field is now available for explanation without adding source or target states.

## Reassessment

Express anchor dependence as a gain field on original durations.

## Checks

```json
{
  "all64": true
}
```
