Distillation

• 🔴 (09:23) User directed that local ownership be replaced with durable multi-node ownership when clustered, recorded as an unchecked TODO in packages/core/src/session/runner/llm.ts.
• 🟡 (09:23) packages/core/src/session/runner/llm.ts was expanded from 439 to 624 lines and added import { and, eq } from "drizzle-orm" plus durable execution ownership logic involving SessionExecutionTable, executionID, ownerID, ownership claims, and owner-checked updates.
• 🟡 (09:23) RunTurn in packages/core/src/session/runner/llm.ts changed from (sessionID, promotion, step) to (sessionID, executionID, promotion, step, ownerID). Both transition paths preserve the same durable execution identity and owner: ContinueAfterOverflowCompaction calls runAfterOverflowCompaction(sessionID, executionID, undefined, defect.transition.step, ownerID), while other turn transitions recurse through runTurn(sessionID, executionID, undefined, defect.transition.step, ownerID).
• 🟡 (09:23) The revised LLM runner includes owner-guarded cancellation/failure handling: "Tool execution declined" invokes publisher.interruptAssistant(...), and database ownership checks combine execution identity with eq(SessionExecutionTable.owner_id, claim.ownerID).
• 🟡 (09:23) The revised LLM runner adds a post-compaction overflow invariant: a second overflow recovery attempt terminates with Effect.die("Post-compaction provider attempt cannot recover another overflow").
• 🟡 (09:24) Event-related files identified were: 1. packages/core/src/event.ts, 2. packages/core/src/public-event-manifest.ts, 3. packages/core/src/session/event.ts, 4. packages/core/src/session/runner/publish-llm-event.ts, 5. packages/core/src/database/migration/20260604172448_event_sourced_session_input.ts, and 6. packages/core/src/database/migration/20260323234822_events.ts.
• 🟡 (09:24) Search found 13 publication-related matches in packages/core/src/event.ts: publish API at line 127; owner-aware replay options at lines 140 and 144; wake publication at line 357; publishEvent at line 369; typed and global PubSub publication at lines 414-415; publish implementation at line 419; publishEvent invocation at line 427; owner-aware options at line 443; conditional publication at line 463; another owner-aware option signature at line 482; and returned publish service member at line 623.
• 🟡 (09:24) packages/core/src/event.ts exposes replay options shaped as { readonly publish?: boolean; readonly ownerID?: string; readonly strictOwner?: boolean }, enabling optional republishing and owner-sensitive replay behavior.
• 🟡 (09:24) packages/core/src/event.ts contains a TODO to bind durable projectors to exact event type+version before incompatible historical payloads are supported.
• 🟡 (09:24) Event publication in packages/core/src/event.ts distinguishes typed and global subscribers: when a typed PubSub exists it executes PubSub.publish(typed, event), then publishes the same event to pubsub.all.
