 #### Sprint 31: End-to-End Quality Assurance (Week 5-8)
 
-- [ ] **E2E-01** — Create golden path test suite. Build `scripts/golden-path-test.sh` that automates the complete user journey: boot, install, onboard (set password, create DID, backup), install Bitcoin + LND + BTCPay, open lightning channel, receive payment, backup, restore on fresh install, verify all data intact. **Acceptance**: Golden path passes on fresh install.
