Action handlers now only see fields from the param table. Extra client
keys are still ignored. Garbage values on declared numbers fail instead
of becoming zero.
Make short TRACE captures independently explain OneBot action and event lifecycles from complete input through a truthful terminal conclusion. Preserve request correlation across asynchronous work while keeping disabled TRACE paths allocation-free and lazy.
Cover shutdown rejection, stream cancellation, event conversion and suppression, reporter invocation settlement, and HTTP delivery outcomes without changing established transport or observer behavior. Add focused regression coverage for lifecycle uniqueness, context reuse, disconnect handling, and quiesce ingress boundaries.
