## Results

```json

  "artifact": {
    "path": "draft/technical_02_rounding.md",
    "sha256": "364c6a7f09422e227c38e3407199b62c4c8e8ed086d065f8dc7f46ec49878c65",

## Finding

The rounding companion gives exact recovery, composition and ambiguity domains, with the Moses path as its concrete application.

## Reassessment

Write the cap information-loss supplement.

## Checks

```json
{
  "nonempty": true,
