Handlers take (props : dval, request : dval) for COMPONENT and TASK and (request : dval) otherwise; every parameter is optional and keeps its name, and request is bound in every handler body. name : capture type fills an omitted argument from the caller variable of that name. Exported (dval) dval functions carry an implicit request capture. Request builtins capture request; redirect writes request.out. The runtime builds one request value per request, passes request and props handles to handlers, applies request.out once after the top-level handler, and drops the pending-props slot, handler frames, per-handler refresh, and current_request(). Core ABI 38, unit ABI 39. Legacy request type checks and the removed-API migration table are gone from the compiler. Documentation, generated routes, tests, and the project home follow; the home page loses the demo and starter. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
