Unified profiles for companies the user works with or researches. Each company gets one file named by slug (acme-corp.md). Contains: company name, user's relationship (customer, partner, employer, prospect, competitor), key contacts (link to knowledge/people/), research findings (overview, products, leadership, funding, news), and CRM data.

CREATE when company appears meaningfully across services or user researches them. UPDATE when new context emerges. Include research sections with findings, sources, and dates. This is the canonical company index including all research and relationship data.
