# C732 — Select the ordered cross-tradition family

## Question

Can one row-to-boundary rule explain the full MT/LXX/SP displacement fields and their rounded residuals?

## Inputs

```json
{
  "source_manifest_sha256": "60159f91fa858a5651da5b097c2e7b5523835ded3757374fed59943b67f4727f",
  "predecessor": "C731",
  "comparison": "whole ordered boundary fields; not repeated endpoint totals"
}
```

## Sources

## Results

```json
{
  "selection": {
    "path": "model/RESEARCH_SELECTION.json",
    "sha256": "f839f7769dfae2e351c0a66baeadae3b71bee524b05302bb3a933706e12b8bbc",

}
```

## Finding

The new cycle will test ordered support and operation compatibility across entire source families. Previous aggregate sums are retained as baseline evidence; the new target is reconstruction of every intermediate boundary and residual.

## Reassessment

Freeze the shared source-row alignment and choose the first complete displacement field.
