Pisco: An Isolation Bug Case Reduction and Deduplication Framework

Summary: Pisco targets isolation-bug triage for DBMSs: deterministic reproduction via internal-state simulation of conflicting op order, then dependency-aware divide-and-conquer reduction of concurrent test cases. Adds a domain-knowledge, multi-agent deduplicator to identify unique bugs amid complex transaction interleavings. (summarized by gpt-5.4-mini on Apr 12 2026)
