WACS.ComponentModel.Async.SourceGen

Roslyn source generator that emits the CanonOpRegistry's static name set at build time. Scans Wacs.ComponentModel.Async.AsyncDispatcher for [CanonAsync(...)]-decorated methods and produces a partial class supplying the registry's BuildKnownNames() implementation. Replaces the Slice G1 reflection path, satisfying the WACS AOT-safety rule.
