Advanced Python - Concurrent Event DAG Correlation
Mission
events.jsonl interleaves randomly ordered events from many services and traces. Starting from the marked auth.failed event, follow the parent-linked causal DAG and concatenate reachable worker.decrypt fragments by logical clock.
Hints
Hint 1 Show
Build a parent-to-children graph rather than trusting line order or trace name alone
Hint 2 Show
Collect only worker.decrypt events reachable from auth.failed with marker=causal-root
Hint 3 Show
Concatenate parts by clock and verify against the reachable digest.commit SHA-256
