# C662 — Resolve phase at the cumulative Jacob junction

## Question

Which macro properties survive replacing the displayed1936 with exact1936.5?

## Inputs

```json
{
  "outer": [
    5436,
    536
  ],
  "display": 1936,
  "exact": "3873/2"
}
```

## Sources

```json
[
  "File70 §§5.8,9.1A; exact-phase caution"
]
```

## Results

```json
{
  "display_arms": [
    3500,
    1400
  ],
  "exact_arms": [
    "6999/2",
    "2801/2"
  ],
  "change": [
    "-1/2",
    "1/2"
  ]
}
```

## Finding

The half-year phase transfers0.5 from the upper arm to the lower arm. The4900 body survives, but its20|8 split in175 units belongs to the whole-year display. A conserved total does not authorize discarding phase.
