## Finding

Final prose now names input-domain intersections correctly, identifies trailing-zero cases precisely, and states the official SP Terah145 condition beside the inherited cumulative field. No numerical model changed.

## Reassessment

Obtain the final text disposition and complete the reproducibility guide.

## Checks

```json
{
  "input_domain": true,
  "zero_wording": true,
  "SP_state": true,
  "old_phrase_removed": true
