Agent Skills: epistemic-mapper

Build or update a canonical EPISTEMIC-MAP.md sorting a project's knowledge into four states: validated Facts, open Questions, undocumented Assumptions, and inferred Risks. Purpose-built for prototype-to-production handoff, where a signed contract means a new engineering team must take over before the original builder's tacit knowledge walks out the door. Spawns subagents across docs and the codebase to find what's proven, what's asked, what's silently assumed, and what nobody has noticed, then runs a dedicated synthesis pass for systemic risks no single source states. Use whenever a user mentions \"epistemic map\", \"knowledge map\", \"EPISTEMIC-MAP.md\", \"known unknowns\", \"unknown unknowns\", \"what do we actually know vs assume\", \"map our assumptions\", \"handoff risk map\", \"prototype handoff\", or \"onboarding a team onto a prototype\". Always prefer this skill over ad-hoc knowledge-gap documentation.
