• 🔴 (23:19) User stated the session-projection rule: “A newer turn supersedes stale incomplete rows; never resume an older assistant projection.” This exact comment appears at packages/core/src/session/projector.ts:142 and again in another visible concatenated source fragment at line 22.
• 🔴 (23:19) User supplied partially elided packages/core/src/session/projector.ts; visible imports include and, desc, eq, gt, or, and sql from drizzle-orm; DateTime, Effect, Layer, and Schema from effect; plus Database, EventV2, makeGlobalNode, SessionEvent, SessionV1, WorkspaceTable, SessionMessage, SessionMessageUpdater, SessionInput, WorkspaceV2, and DeepMutable.
• 🔴 (23:19) Visible packages/core/src/session/projector.ts SQL-table imports are MessageTable, PartTable, SessionInputTable, SessionMessageTable, SessionRecoveryTable, and SessionTable.
• 🔴 (23:19) The supplied source visibly registers a projection for SessionEvent.Compaction.Ended via events.project(SessionEvent.Compaction.Ended, (event) => run(db, event)).
• 🔴 (23:19) Visible source changes add delivery: event.data.delivery and a "session.next.step.interrupted": (event) => { ... } handler; surrounding implementations were elided, so complete behavior is not established by the supplied output.
