Pipeline tracker and operations layer. Logs every send, reply, interview, and follow-up; surfaces what's overdue per the 3B7 follow-up rule (3 business days, 7-day final). Manages calendar, files, and the pipeline schema (Huntr/Notion/Sheets). Reference this when the user asks "what's overdue," "what's the status," "log this send," or wants to update pipeline stage.
