• 🔴 (13:27) User’s patch changes packages/core/src/session/runner/publish-llm-event.ts so createLLMEventPublisher input includes startCommit: (assistantMessageID: SessionMessage.ID) => Effect.Effect<void>.
• 🔴 (13:27) User’s createLLMEventPublisher patch introduces publishEvent(...), which distinguishes event definitions having durable behavior and supports publishing them with an associated commit effect.
• 🔴 (13:27) User’s publisher now creates the assistant message ID with SessionMessage.ID.create() when starting an assistant message and couples publication to input.startCommit(created).
• 🔴 (13:27) User’s publisher adds interruptAssistant(message): it flushes buffered output before publishing SessionEvent.Step.Interrupted with error: { type: "unknown", message }.
• 🔴 (13:27) User’s runner invokes publisher.interruptAssistant("Provider Step outcome unknown after interruption") when a provider step’s outcome cannot be determined following interruption.
• 🔴 (13:27) User’s publisher routes assistant, text, reasoning, tool, step-failure, and step-interruption events through the new publishEvent(...) path, including SessionEvent.Text.Started, SessionEvent.Reasoning.Delta, SessionEvent.Tool.Success, and SessionEvent.Step.Interrupted.
• 🔴 (13:27) User’s patch adds the event definition PromptExecutionRequested with wire type "session.next.prompt.execution_requested".
• 🔴 (13:27) User’s patch adds Step.Interrupted with wire type "session.next.step.interrupted" and Step.Recovered with wire type "session.next.step.recovered"; recovered phases are exactly "ready", "unknown", and "continue".
• 🔴 (13:27) User’s patch registers PromptExecutionRequested, Step.Interrupted, and Step.Recovered in the session event collections/unions and propagates them into generated SDK types in packages/sdk/js/src/v2/gen/types.gen.ts, including GlobalEvent, sync-event unions, and exported event payload types.
