## Results

```json
{
  "main_additions": [
    "source910=460+450 and SP120+1980=2100",
    "three cumulative restoration spans and51-unit common addition",
    "whole MT–LXX7000 packet",
    "three-placement4900 family with910 and600 transports",
    "12600=(8+3+7)×700 and its authorized2700-forward form",
    "brief source explanation of SP9800/11270 and LXX70-unit refinement"
  ],
  "support_only": [
    "complete36-span target table",
    "rank3 interval matrix",
    "full source row and cut-domain checks"
  ],
  "reason": "Named whole packets show how the families fit together without extending the mirror branch or overloading the main reader."
}
```

## Finding

The main addition will emphasize complete named paths, the source-generated910/2100 differences, and the600 translation linking restoration to AD65. Detailed residue tables remain in the companion.

## Reassessment

Draft the concise report integration and have its source roles and conventions independently reviewed.
