Ten recipes: lamp, colour lamp, thermostat, blind, lock (deferred), contact sensor (ChangeReport), scene, doorbell (raise), typed errors, and a plug as an ES module. Each reads ALEX2MQTT_USERNAME, _PASSWORD and _ROOT_TOPIC and names the ones that are missing. The nine examples of 1.5.2 move to examples/legacy unchanged. test/examples.test.js starts every file with node, its broker connection sent to a broker on 127.0.0.1 (test/helpers/loopback.js), discovers the device, sends directives and checks the answers. A legacy file is started and its discovery compared with the answer the 1.5.2 build gave, recorded in test/fixtures/legacy-examples. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
