# Reset a system setting to ENV / built-in default

`DELETE /system/admin/settings/{key}`

Removes the DB override for :key so the 3-tier resolver
falls back to the environment variable (when configured)
or the in-code default. Idempotent — resetting a key
that was never persisted returns 200.

## Path parameters

- `key` string, required

## Response `200`

Reset acknowledged

## Other responses

- `400` — Unknown key
- `500` — DB write failed
