arsura

Hunts for correctness, concurrency, and security bugs in clicko, a ClickHouse migration tool. Cross-references README.md (documented/expected behavior) and IMPROVEMENT.md (backlog of past review rounds, including declined/deferred items with reasons) so it never re-reports known or already-decided issues, then appends new findings to IMPROVEMENT.md in the repo's established round format. Use when asked to find bugs, do a bug hunt, run a review round, or update clicko's improvement backlog.
