Opening a changed file from a session-origin Source Control sends
files.openDiff, which needs a renderer notifier. The e2e pairs against
`orca serve --mobile-pairing`, which has none, so the host answers
renderer_unavailable on native and hybrid alike. The journey asserted the diff
tab unconditionally and could never pass.
The native baseline now probes the same session-origin path and records what
the paired host answered. The hosted journey takes whichever arrives first, the
diff route or the bridge error, and pins it against the native result, so the
claim is "hybrid matches native on this host" rather than "hybrid fails". On a
full desktop the diff route wins and reviewOpen.headless records false.
Kept as evidence, not fixed: the hybrid banner reads "Source control action
failed" where native names renderer_unavailable.
