## Decision

Decision update: split Backend Runtime work into three implementation tickets.

1. 00001KVZKSV6C Backend RuntimeRegistryの基盤をworker-runtime向けに整理する
   - Registry identity/projection/error boundary only.
   - No embedded Runtime handle implementation.
   - No remote Runtime client implementation.
2. 00001KVZSGT0Q Backend RuntimeRegistryにembedded worker-runtimeを接続する
   - Direct lib-call integration for backend-internal Runtime.
3. 00001KVZSGT14 Backend RuntimeRegistryにremote worker-runtime processを接続する
   - HTTP/event-stream client integration for remote Runtime processes.

Companion Web Console depends on embedded integration, not remote integration.
