Filter declared chain firings by date range, chain (parent rail / template name), completion status, and (cascading) metadata key + value. One row per parent transfer firing; completion_status reads 'Completed' when every Required child declared for the parent fired against this transfer_id, 'Incomplete' if any required child is missing, 'No Required Children' when only optional / XOR-group children are declared.
One row per parent transfer firing. completion_status reads 'Completed' iff every Required child declared for the parent fired against this transfer_id; 'Incomplete' if any required child is missing. With no Metadata Key picked, every firing in the date window appears.
