// Package acceptance provides AS-5: OTA update succeeds / rollback on bad firmware.
//
// Pass criteria:
// - spaxel-sim --scenario ota simulates successful OTA
// - Node firmware version increments after update
// - VERIFIED badge appears within 10 minutes
// - Rollback scenario: --scenario ota --ota-failure triggers rollback
// - Rollback firmware boots within 30 seconds
//
// Fail criteria:
// - Update fails or node gets stuck in FAILED state
// - Rollback doesn't trigger on boot failure
