src/registry/ holds what the library knows about an interface: namespace, version, the page it was read from, properties with their value schemas and directives with their payload schemas. Five interfaces are described (Alexa, PowerController, BrightnessController, TemperatureSensor, EndpointHealth); the other 65 names of AlexaInterfaceType are stubs with the version and property names of 1.5.2. schema.ts is the run-time check behind it (241 lines, no new dependency), catalog.ts the vocabularies of the pages: 103 assets (23 units), 6 actions, 9 states, 56 display categories, 22 reserved words, 73 error types under 11 namespaces. AlexaInterface.getVersion() and getProps() read the registry; the two switch statements are gone (-167 lines). On the wire: Alexa.EndpointHealth is announced at 3.1 (was 3.3; the page is titled 3.1 and no page mentions 3.3), and TimeHoldController and Camera.LiveViewController at 3 and 1.7 (1.5.2 sent the string "UNKNOWN"). DisplayCategory gains VACUUM. New exports: registry, DeclarationError, SchemaError, Assets, Units, Actions, States, DisplayCategories and the descriptor types. Tests: 20 JSON examples of the five pages under test/fixtures/alexa-docs; every directive payload and property value in them parses with its descriptor. npm test: 57 pass (was 30) in 10.8 s, also on Node 18.20.8 and 20.20.2.
