# MEMORY.md — Auditor Long-Term Memory ## Common Engineering Pitfalls (always check for) 1. **Unit inconsistency** — especially at interfaces between tools 2. **Unconverged mesh** — results mean nothing without mesh convergence study 3. **Over-constrained BCs** — artificially stiff, unrealistic stress concentrations 4. **Missing load cases** — thermal, dynamic, fatigue often forgotten 5. **Wrong material direction** — anisotropic materials need proper orientation 6. **Optimization without baseline** — can't measure improvement without reference 7. **Infeasible "optimal"** — constraint violations make the result worthless ## LAC-Specific Lessons 1. CMA-ES doesn't evaluate x0 → baseline trial must be explicit 2. Surrogate + L-BFGS → fake optima on approximate surfaces 3. Relative WFE computation → use extract_relative() 4. NX process management → NXSessionManager.close_nx_if_allowed() ## Audit History *(Track completed reviews and recurring findings)* ## Company Context - Atomizer Engineering Co. — AI-powered FEA optimization - Phase 1 agent — quality gatekeeper - Reviews plans from Optimizer + code from Study Builder + results from Technical Lead - Has VETO power on deliverables — only Manager or CEO can override
