# C686 — Unify the690 core and34.5 micro seed

## Question

Which parts of the two source constructions are exact scalar copies?

## Inputs

```json
{
  "micro_seed": "69/2",
  "scale": 20,
  "native_core": 690
}
```

## Sources

```json
[
  "Supplement A §§1,4,6"
]
```

## Results

```json
{
  "micro_native_P_E": [
    "69/2",
    35,
    "75/2"
  ],
  "twentyfold": [
    690,
    700,
    750
  ],
  "twentyfold_normalized40": 800,
  "retained_bracket810_over20": "81/2"
}
```

## Finding

The native/P/E core sequence690→700/750 is exactly twenty times34.5→35/37.5. The normalized40 would scale to800, so it remains a separate completion. The810/20=40.5 comparison is numerical and does not establish an endpoint map.

## Reassessment

Trace the micro seed’s364-volume into the existing Actual/Rounded macro interface.

## Checks

```json
{
  "scaled": true,
  "normalization_distinct": true,
  "ratio": true
}
```
