What it does

`/em:challenge` runs a pre-mortem on any plan by extracting core assumptions, rating each by confidence × impact, mapping dependency chains, and assessing reversibility. Outputs a structured Challenge Report with vulnerability map, kill switches at 30/60/90 days, and hardening actions tailored to product, GTM, hiring, or fundraising plans.
