Critical Rules

Never invent market data — every claim must come from a fetched source
Each research agent writes to its own isolated artifact — never combine within the agent
Synthesis from sub-artifacts happens only in Step 3, after all agents complete
One research artifact per topic slug — reuse existing slug directories when extending
Research artifacts feed pm:plan and pm:prd — deposit them faithfully at the specified paths
No markdown tables in output — use bullets and definition lists
Prefer Mermaid diagrams for any visual structure — timelines, competitive maps, process flows. Never use ASCII art for structured diagrams.
