• 🟡 (08:58) /home/byk/Code/opencode/packages/core/src/session/event.ts re-exports all symbols from @opencode-ai/schema/session-event and exposes the namespace as SessionEvent.
• 🟡 (08:58) /home/byk/Code/opencode/packages/core/src/session/prompt.ts exports AgentAttachment, FileAttachment, Prompt, and Source from @opencode-ai/schema/prompt.
• 🟡 (08:58) /home/byk/Code/opencode/packages/core/src/session/input.ts implements durable prompt-input lifecycle operations: find, admit, projectAdmitted, projectPrompted, hasPending, equivalent, promoteSteers, and promoteNextQueued.
• 🟡 (08:58) SessionInput.admit is idempotent by SessionMessage.ID: it first calls find, publishes SessionEvent.PromptAdmitted only when absent, requires event.durable.seq as admittedSeq, and on a publication defect re-reads storage before rethrowing the defect.
• 🟡 (08:58) SessionInput.projectAdmitted rejects lifecycle collisions with SessionInput.LifecycleConflict: it dies if the same ID already exists in SessionMessageTable, inserts into SessionInputTable with .onConflictDoNothing(), and dies if no row was inserted.
• 🟡 (08:58) SessionInput.projectPrompted atomically sets promoted_seq only where the matching input has promoted_seq IS NULL; it validates sessionID, encoded prompt, delivery, and timeCreated via matchesProjection. If the admitted row is missing, it inserts one with both admitted_seq and promoted_seq equal to the supplied promotedSeq.
• 🟡 (08:58) Pending input selection in /home/byk/Code/opencode/packages/core/src/session/input.ts is delivery-specific: promoteSteers publishes every unpromoted "steer" with admitted_seq <= cutoff in ascending admitted_seq order, while promoteNextQueued publishes only the earliest unpromoted "queue" and returns false if none exists.
• 🟡 (08:58) SessionInput.publish emits SessionEvent.Prompted for each selected row and returns rows.length; a LifecycleConflict is tolerated only when a re-read shows that the input already has a promotedSeq.
• 🟡 (08:59) /home/byk/Code/opencode/packages/core/src/session/runner/index.ts defines SessionRunner.Interface.run({ sessionID, force }), returning Effect.Effect<void, RunError>; RunError includes LLMError, SessionRunnerModel.Error, MessageDecodeError, ContextSnapshotDecodeError, SystemContext.InitializationBlocked, and ToolOutputStore.Error.
• 🟡 (08:59) SessionRunner.Interface.run is documented as draining eligible durable work; an explicit run performs one provider attempt even when no work is eligible. /home/byk/Code/opencode/packages/core/src/session/execution/local.ts invokes it as runner.run({ sessionID, force }).
• 🔴 (08:59) User directed that clustered operation replace local ownership with durable multi-node ownership: “Replace local ownership with durable multi-node ownership when clustered.”
• 🟡 (08:59) The runner checklist in /home/byk/Code/opencode/packages/core/src/session/runner/llm.ts marks streaming exactly one llm.stream(request) provider turn as complete and retains TODOs to: bound provider retries and repeated identical tool calls; add scoped runtime context, progress updates, and attachment normalization; and update title, summaries, compaction state, and cleanup through bounded background work.
