# C1438 — Reconstruct MT convergence at component level

## Question

What compensates when MT switches from Regular to Cumulative source measurement?

## Sources

```json
[
  "File52c §3.3–3.4"
]
```

## Results

```json
{
  "source_mode_gap": 9900,
  "reversed_component_differences": [
    -1580,
    1580
  ],
  "head_gap": 0,
  "gain_regular": 7920,
  "gain_cumulative": -1980
}
```

## Finding

MT switches between source measurements differing9900, but its reversed component changes−1580 and+1580 cancel.

## Reassessment

Test whether the LXX divergence has the same local compensation structure.

## Checks

```json
{
  "exact_compensation": true
}
```
