Full R0-R13 calculation engine with: - Guided data collection (N bolts, per-bolt load, DA_prime, thermal dT) - Auto-sizing script (M4->M39 iteration across strength classes) - fm_table A1 lookup for fast MA/FM queries without full R0-R13 - Warnings for stainless steel galling, ESV insert threads (Helicoil/Ensat) - Bolt circle load distribution formula (FA + MB + MT) - 7 evals covering static, fatigue, ESV aluminium, pressure seal, thermal steel-aluminium, and combined FA+FQ cases Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
