# getRunDiff

> Gateway RPC for the final run-level diff.

* Method: `getRunDiff`
* Scope: `run:read`
* Transports: HTTP RPC, WebSocket RPC
* Request: `{ runId }`
* Response: `GetRunDiffResponse` (`DiffBundle` or an explicit `status: "oversized"` marker)

The bundle is computed from the run's base VCS revision to its terminal revision. Runs with no changed files return an honest empty `patches` array. Oversized results are never truncated and include `sizeBytes` and `maxBytes`.

Errors are versioned as `v1` and include `InvalidRequest`, `Unauthorized`, `Forbidden`, `RunNotFound`, `VcsError`, and `Internal`.
