Month 1: fire with ferro rod AND bow-drill attempt; assemble water storage; bucket-toilet dry run. Month 2: cook a full day on the rocket stove; camp one night in the garden with go-bags only. Month 3: first-aid course; can something; start sprouts + compost. Month 4: 48-h "grid-down weekend" — mains water and power off, live the plan, log every failure into the app. Repeat quarterly. Every failure found in practice is a failure that doesn't happen for real.
