Make create fail when blackboard document already exists
save() treats expected_revision=None as an unconditional update by copying the current revision and writing anyway, so create() can overwrite an existing session document instead of failing. If two workers race through get_or_create on the same new session_id, the later create can clobber data written by the first request (resetting state back to initial_data) while still advancing the revision, which is a real state-corruption risk for concurrent workflows.
Useful? React with 👍 / 👎.
