Documents the original 17-agent organization with C-suite roles, Pai orchestrator, bot-wiki coordination, and per-agent knowledge bases.

Agent Ecosystem v1 — 17-Agent C-Suite Hierarchy

Documents the transition from 17 agents to 5, driven by lessons from Anthropic best practices, OWASP LLM Top 10, and practical experience.

Agent Ecosystem v2 — 5-Agent Flat Structure

Documents the addition of analyst and synthesizer agents, driven by Deep Research workflows and the need for structured research ingestion.

Agent Ecosystem v3 — 7-Agent Structure with Research Tools
