What
Cloud review failures on a checkout with no branches now return a dedicated no_merge_base error telling you to create a branch first, and the "shares no history with HEAD" message suggests passing the real base branch explicitly.
Details
detached-HEAD checkouts previously fell through to a generic bundling failure
the no-shared-history path now names the likely cause rather than only reporting it
Evidence
Your checkout has no branches (detached HEAD only), which cloud review can't bundle.
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
