Agentic lead-gen Flywheel snapshot — the growth loop read end-to- end as one funnel: discovery → agent acquisition → agent activation → pull-through → listener conversion → retention → monetization, with the headline flywheel coefficient (partner surfaces created ÷ new listeners) on top.

Fan-reads the (already-cached) Distribution & Discovery snapshot for the agent / listener / subscription / discovery-source stages, then layers on the flywheel-specific reads:

• cross-embedder embedder_revenue_events rollup folded into the clicks→signups→deposits→sales ladder + a house-vs-attributed split (our first-party surface vs real partner embedders);
• new-vs-returning MCP callers (first-seen vs repeat);
• the pull-through stage (plays + subs carrying an embedder attribution) — instrumented: false until the additive source_embedder_slug / referred_by_embedder_slug columns land, then it lights up automatically (runtime column probe).
