Ln 650 Persistence Performance Auditor

This is an L2 coordinator that runs a full persistence and performance audit by delegating to four specialized workers: query efficiency, transaction correctness, runtime performance, and resource lifecycle. It enforces mandatory research before scoring, aggregates findings into a single deduplicated report with remediation plans, and cleans up temporary artifacts when done. The runtime contract walks through seven phases from config to self-check. You'd reach for this when you need a structured, evidence-based audit of your data layer rather than ad-hoc performance checks. The coordination overhead pays off if you want repeatable audits with proper research citations and actionable remediation steps.
