# Get Decision Evidence

`GET /snapshots/{snapshot_id}/decisions/{decision_index}/evidence`

Return the provenance evidence rows for a single decision (0.13.0).

Each row mirrors the OSS ``DecisionEvidence`` shape (source, source_rank,
evidence_file/line/commit, source_quote, confidence, verification). Legacy
artifacts written before 0.13.0 carry no ``evidence`` array — those return
an empty list rather than 404. 404 is reserved for an out-of-range index.

## Path parameters

- `snapshot_id` string, required
- `decision_index` integer, required

## Response `200`
