# C1496 — Check the whole-span alternative

## Question

Would expanding all 12530 years by 70/69 reproduce the same total?

## Sources

```json
[
  "Strategy.md §5C"
]
```

## Opened utc

2026-09-29T02:27:50.284677+00:00

## Results

```json
{
  "whole_expansion": "877100/69",
  "excess_over12600": "7700/69",
  "extra_gain_on7700": "7700/69"
}
```

## Finding

Whole-span expansion exceeds 12600 by 7700/69; the successful relation is explicitly a local Key action.

## Reassessment

Read the source’s two 1260 decompositions before their tenfold placement.
