parsing when the corresponding blocks never execute. Bug Fixes: • Ensure per-block system database sessions are closed for blocks that do not execute, including dry runs, install-only runs, and parsing failures. Enhancements: • Make block parsing explicitly track and clean up all sessions it creates, including sessions from incomplete block sets. Tests: • Add coverage verifying parser session cleanup for dry runs, plugin commands, extract-load blocks, and parse errors. meltano/meltano
