# Get File Detail

`GET /snapshots/{snapshot_id}/files/detail`

One-call canonical file page: wiki, health, git, coverage, graph,
symbols, function blame, governing decisions and dead code.

Every block degrades to None / [] when its layer is absent for the
snapshot, so the page renders on partial indexes.

## Path parameters

- `snapshot_id` string, required

## Query parameters

- `path` string, required — Source file path

## Response `200`
