# C1463 — Distinguish anchor change from whole-pair translation

## Question

Does moving only4106 to4116 close the ten-year two-Key discrepancy?

## Sources

```json
[
  "Two-Key nearby route"
]
```

## Results

```json
{
  "original": 14106,
  "anchor_only": "324418/23",
  "both_input_and_anchor": 14116,
  "anchor_only_change": "-20/23",
  "required_pair_translation": 10
}
```

## Finding

Changing only the held anchor adds−20/23, not+10; translating source and anchor together adds10. The source states cannot be exchanged silently.

## Reassessment

Use a genuinely shared pair of source-appointed anchors to understand the LXX386 convergence.

## Checks

```json
{
  "anchor_change_exact": true,
  "whole_pair_exact": true
}
```
