Root task complete — all 6 child tasks delivered. ContactOut deep-dive concluded: bootstrapped B2B contact-data platform ($10M+ revenue, 800M profiles, 150M personal emails, 200M work emails, 100M direct dials, 40M company profiles), Chrome extension + Search Portal + 17-endpoint REST API + MCP server.
Strengths: best-in-class personal email coverage; MCP server for AI-native queries; 17-endpoint REST API
Weaknesses: no criminal/address/property/court data; 50-60% phone accuracy; hidden fair-use caps; Trustpilot 1.3-1.4/5; sales-gated API
Phase 0B Score: 3.7/10
Final Recommendation: Skip ContactOut for Phase 0b — not a background-check tool
Decomposed into t_f62dd5d7, t_9bebe7d8, t_9ef0d1d7, t_5e89a527, t_f7efaba0, t_1b7ec3c8. Root will wake when all children complete.
