Build comprehensive malware analysis knowledge base from 3 sources: - SANS FOR610 course: 120 tools, 47 labs, 15 workflows, 27 recipes - REMnux salt-states: 340 packages parsed from GitHub - REMnux docs: 280+ tools scraped from docs.remnux.org Master inventory merges all sources into 447 tools with help tiers (rich/standard/basic). Pipeline generates: tools.db (397 entries), 397 cheatsheets with multi-tool recipes, 15 workflow guides, 224 TLDR pages, and coverage reports.
