Documents the UI component primitives (Thread, Composer, Message, etc.) for building AI chat interfaces with the assistant-ui library.

Operator wrapper for ECC's research stack (`exa-search`, `deep-research`, `market-research`, `lead-intelligence`, `knowledge-ops`) that picks the lightest useful evidence path and separates sourced facts from user-supplied context, inference, and recommendation in every answer. Adds dates to freshness-sensitive outputs and flags recurring lookups that should graduate into a monitoring workflow instead of being re-asked.
