• 🔴 (23:20) User specified a pending architecture requirement: “Replace local ownership with durable multi-node ownership when clustered.”
• 🔴 (23:20) User specified that processes which never serve the HTTP API—specifically CLI and scripts—should not pay the associated cost at module load.
• 🔴 (23:20) Supplied session-execution code documents that exactly one llm.stream(request) provider turn is streamed and defines continueAfterCompaction = (step: number) => new TurnTransitionError({ _tag: "ContinueAfterCompaction", step }).
• 🔴 (23:20) Supplied session-execution code states that declining a user prompt halts the loop rather than becoming model-facing tool output.
• 🔴 (23:20) Supplied session-execution code uses publisher.failUnsettledTools("Tool execution outcome unknown after interruption") for unsettled tool calls after interruption.
• 🔴 (23:20) packages/core/src/session/compaction.ts defines exact defaults: DEFAULT_BUFFER = 20_000, DEFAULT_KEEP_TOKENS = 8_000, TOOL_OUTPUT_MAX_CHARS = 2_000, and SUMMARY_OUTPUT_TOKENS = 4_096.
• 🔴 (23:20) packages/core/src/session/compaction.ts defines SUMMARY_TEMPLATE with sections in this exact order: ## Objective, ## Important Details, ## Work State (including ### Completed), and ## Next Move; instructions require preserving the section order, omitting the <template> tags, using terse bullets rather than prose paragraphs, and moving completed work from “Active” to “Completed.”
• 🔴 (23:20) packages/core/src/session/compaction.ts serializes shell messages as [Shell]: ${message.command}\n${truncate(message.output)} and completed tool output using [Tool result]: ${truncate(serializeToolContent(part.state.content))}.
• 🔴 (23:20) packages/core/src/session/compaction.ts collects summary text only when LLMEvent.is.textDelta(event) is true, appending event.text to chunks.
• 🔴 (23:20) packages/core/src/session/compaction.ts computes available context using context - Math.max(output, config.buffer).
• 🔴 (23:20) packages/server/src/routes.ts imports SessionExecution from @opencode-ai/core/session/execution and SessionExecutionLocal from @opencode-ai/core/session/execution/local; its service layer is built with AppNodeBuilder.build(applicationServices, [[SessionExecution.node, SessionExecutionLocal.node]]).
• 🔴 (23:20) packages/server/src/routes.ts also wires core services including Database, EventV2, Credential, PermissionSaved, PtyTicket, SessionV2, SessionRecovery, ToolOutputStore, and LocationServiceMap.node.
• 🔴 (23:20) packages/opencode/src/server/routes/instance/httpapi/server.ts contains lazy server-related module behavior so non-serving processes such as CLI and scripts avoid module-load cost; visible route composition includes rootApiRoutes, instanceApiRoutes, instanceRoutes, workspaceRoutingLayer, and authorizationRouterMiddleware.
