workflows

I have shipped Mastra across six TypeScript codebases over the full 1.x line — a market-intelligence API, an autonomous-CMO product, a crypto trading agent, a personal assistant. This is the comprehensive operator playbook: memory's four layers, tools and workflows, supervisors, MCP on both ends, RAG and evals, the free server and auth layers, observability, the whole 1.x migration history, and the production bugs that taught me the most.
