• 🔴 (08:22) User stated protected paths must “never be watched.”
• 🟡 (08:22) User inspected /home/byk/Code/opencode/packages/core/test/session-runner.test.ts lines 1600-1849. Tests cover: durable provider reasoning metadata replay (anthropic.signature, openai.itemId, openai.reasoningEncryptedContent); inline replay of provider-executed web_search tool calls/results; eager parallel execution of 5 recorded local echo tools with maxActiveToolExecutions exactly 5 while blocking provider continuation until settlement; repeated provider-local tool-call ID tool_0 settling against the correct owning assistant messages before and after replaySessionProjection(sessionID); and joining concurrent resume calls into one active provider run.
• 🟡 (08:22) In test "starts recorded local tools eagerly and awaits settlement before continuing" at /home/byk/Code/opencode/packages/core/test/session-runner.test.ts:1687, 5 calls named call-echo-0 through call-echo-4 are started concurrently; context shows all 5 as status: "running", requests remains length 1 after the provider finishes, and becomes length 2 only after toolExecutionGate settles.
• 🟡 (08:22) In test "settles repeated provider-local tool call IDs against their owning assistant messages" at /home/byk/Code/opencode/packages/core/test/session-runner.test.ts:1748, two sequential echo executions reuse ID tool_0 with inputs/results "first" and "second"; execution order is ["first", "second"], exactly 3 provider requests occur, and both completed results remain attached to their respective assistant messages after projection replay.
• 🟡 (08:22) User’s broad search found exactly 75 matches involving scanning, wakeups, startup, pending session inputs, and execution coordination. Key files included /home/byk/Code/opencode/packages/core/src/session/run-coordinator.ts, /home/byk/Code/opencode/packages/core/src/session/execution.ts, /home/byk/Code/opencode/packages/core/src/session/execution/local.ts, /home/byk/Code/opencode/packages/core/src/session/runner/llm.ts, /home/byk/Code/opencode/packages/core/src/event.ts, /home/byk/Code/opencode/packages/core/src/session/input.ts, and /home/byk/Code/opencode/packages/core/src/filesystem/protected.ts.
• 🟡 (08:22) /home/byk/Code/opencode/packages/core/src/session/execution.ts documents wake(sessionID) as registering newly recorded work and allowing repeated wakeups to coalesce; /home/byk/Code/opencode/packages/core/src/session/runner/llm.ts documents one local active drain per session, explicit resumes joining, and prompt wakeups coalescing.
• 🟡 (08:22) User traced SessionExecutionLocal integration: /home/byk/Code/opencode/packages/opencode/src/session/session.ts:14 imports @opencode-ai/core/session/execution/local; /home/byk/Code/opencode/packages/opencode/src/server/routes/instance/httpapi/server.ts:301 wires [SessionExecution.node, SessionExecutionLocal.node]; and /home/byk/Code/opencode/packages/server/src/routes.ts:52 supplies the same service-to-local-layer pairing through AppNodeBuilder.build(...).
• 🟡 (08:22) User inspected /home/byk/Code/opencode/packages/opencode/src/session/session.ts: cancelBackgroundJobs() cancels all running jobs whose job.id, metadata.sessionId, or metadata.parentSessionId matches the session, with unbounded concurrency; listByProject() filters by project/workspace/path/directory/root/start/search, orders by SessionTable.time_updated descending, and defaults to a limit of exactly 100; the exported node depends on BackgroundJob.node, RuntimeFlags.node, Database.node, and EventV2Bridge.node.
• 🟡 (08:23) User inspected durable-event ownership schema in /home/byk/Code/opencode/packages/core/src/event/sql.ts: EventSequenceTable stores aggregate_id as primary key, seq, and nullable owner_id; EventTable stores durable events with cascade deletion from EventSequenceTable, unique index event_aggregate_seq_idx on (aggregate_id, seq), and index event_aggregate_type_seq_idx on (aggregate_id, type, seq).
• 🟡 (08:23) User traced event ownership logic in /home/byk/Code/opencode/packages/core/src/event.ts: replay APIs accept ownerID and strictOwner; strict replay can fail with Replay owner mismatch for aggregate ...; ownership may be populated when currently null; claim(aggregateID, ownerID) updates EventSequenceTable.owner_id.
• 🟡 (08:23) User inspected durable event streaming in /home/byk/Code/opencode/packages/core/src/event.ts:541-604: readAfter(aggregateID, after) reads events where seq > after in ascending sequence; subscribeDurable() creates a sliding PubSub<void>(1) wake channel registered per aggregate and removes/shuts it down on scope release; durable() starts at after ?? -1, emits historical events, updates its cursor from the last durable sequence, and then rereads/streams events after each wake.
