[v3-3-test] Clarify AssetPartitionDagRun provisional-run docstring (#69982)#70104
Merged
Conversation
…69982) The previous wording ("we should not allow more than one like this") did not state the actual invariant. Make explicit that rows are never deleted — so multiple records per target_dag_id/partition_key are expected — and that the constraint is specifically at most one row with a null created_dag_run_id, which the _lock_asset_model mutex enforces.
