26 rewrites cloud_backup from async to synchronous AND deletes get_dataset_recursive(), which SNAPSHOT_BLOCK called out of the host module's namespace. Either is a broken backup found at restore time. The nested module is now one synchronous implementation talking to middlewared via call_sync, behind two thin wrappers. apply.sh reads which flavour the installed middleware declares and injects the matching one: <= 25.10 reaches it through 'await middleware.run_in_thread(...)', 26 is already in a worker thread and calls it directly. The snapshot/bind-mount/failure logic exists once -- an async twin would mean every future fix had to land twice. A middleware whose three wrapped functions disagree about asyncness is refused, not guessed at. get_dataset_recursive is vendored, removing the dependency on both versions rather than asserting it. master stays BROKEN on purpose: iX are still renaming middleware->context, cloud_backup->entry and adding a required credentials param there. Chasing a branch that moves daily is how you ship a patch nobody tested.
