Make the acceptance harness's GitHub file-list cross-check exclude the discovery directory, so a pull request that touches discovery prose is not reported as a range mismatch.
Meta
The range the distiller recomputes already excludes the discovery directory alongside the queue, in the git-diff based helpers. The harness's own cross-check filters GitHub's file list by string prefix instead, and it still strips only the queue path. An acceptance run against a pull request that touches discovery prose therefore reports a file-set mismatch that is not a real mismatch. The check is advisory today, so the failure is a misleading report rather than a wrong result.
