• 🔴 (08:36) User directed that local session-execution ownership be replaced with durable multi-node ownership when clustered.
• 🟡 (08:36) packages/core/src/session/runner/index.ts is intended to remain orchestration over smaller collaborators rather than rebuilding the legacy implementation.
• 🟡 (08:36) packages/core/src/session/runner/index.ts starts each recorded local call eagerly and awaits all settlements before continuation.
• 🟡 (08:36) Durable continuation recovery in packages/core/src/session/runner/index.ts remains a future slice requiring an explicit retry policy.
• 🟡 (08:36) packages/core/src/session/runner/index.ts sends provider requests with the header "x-session-affinity": session.id.
• 🟡 (08:36) The runner captures a start snapshot via snapshots.capture() before executing the provider turn.
• 🟡 (08:36) The runner skips work when it is not recovering, input.force is false, and neither steer nor queued input exists; continuation processing then loops while needsContinuation is true.
• 🟡 (08:36) The LLM event publisher created by createLLMEventPublisher(events, input) tracks tool calls in a Map and enforces event-order invariants with defects including Tool input end before start: ${callID}, Tool input end before start: ${event.id}, and Tool input delta before start: ${event.id}.
