 - Select runtime behavior from `CoreRuntime.kind`, not `instanceof` adapter classes; NAPI maps to the native runtime kind and wasm maps to wasm.
 - Keep `CoreRuntime` SQL methods on the portable `RuntimeSql*` structs from `packages/rivetkit/src/registry/runtime.ts`; NAPI-only `Buffer` conversion belongs inside `NapiCoreRuntime`.
 - Keep `CoreRuntime` byte payloads on `RuntimeBytes`/`Uint8Array`; NAPI-only `Buffer` conversion belongs inside `NapiCoreRuntime`.
+- Shared actor glue in `packages/rivetkit/src/registry/native.ts` should construct `RuntimeBytes`/`Uint8Array`; leave `Buffer` creation to `NapiCoreRuntime`.
 - Wasm bindings for NAPI-supported runtime APIs should forward to `rivetkit-core`; avoid placeholder returns that break runtime parity.
 - Use public `sqlite` config for runtime SQLite backend selection; wasm defaults unset SQLite to remote and must reject local before runtime construction.
