A message queued behind a running turn started in the thread's modes at the moment the queue reached it, not the modes it was sent with. Clients set the thread's runtime and interaction modes before every send, including sends that only queue. So with Follow-up behavior set to "Queue", queuing A in Plan mode and then B in Default mode ran A in Default mode. The runtime (permission) mode took the same path, so a message queued under approval-required could run with full access.
message.dispatch creates records the runtimeMode and interactionMode of its send: immediate, deferred while a worktree is prepared, queued, and fork/merge-back. A steering restart records the restarting send's modes. Both fields are optional on OrchestrationV2Run and stored in the existing run payload, so no migration is needed and older rows fall back to the thread's modes.ProviderTurnStartService) resolves the provider runtime policy from the run's modes. Wakes that follow the current conversation (monitor notifications, delegated completions) keep the thread's current modes, as they already do for model selection.runModes. MCP caller limits and delegation defaults come from the caller's active run. Steering, restarting, promoting into, or answering requests for an active run is checked against that run's modes. Editing, starting, or resuming queued runs is checked against the queued run's modes.Fixes pingdotgg/t3code#31290

c97bd48Resolved by Julius Marmingec97bd48Resolved by Julius MarmingeVerdict: Needs Human Approval
Macroscope's review found this PR requires human approval — Queued messages now retain their send-time modes, including potentially higher permissions than the thread currently shows. Human confirmation is needed that lowering a thread’s mode should leave previously queued work authorized to execute with those earlier permissions.

Runs now record the runtime and interaction modes active when sent. Queued execution, provider-session restarts, dispatch-limit checks, and MCP caller limits use run-specific modes, with thread modes as a fallback for older records.

Explanation
The title names the primary change: queued messages now run in the runtime and interaction modes they were sent with. It follows the conventional commit form and is specific. The raw summary and objectives both center on this behavior, so the title is related to the main change.
Explanation
The description follows the template. It has Problem, Change, Scope and approval, and Verification sections. The Problem section gives the bug, reproduction steps, and expected behavior. The Change section explains the fix across the server components. The Scope section links issue #31290 and says it was triaged. The Verification section lists focused tests, a before/after runtime transcript, and items not checked. The template's requirement for a maintainer-approval link is only partly met. The description cites an automated triage flow and a GitCafe issue, not an explicit maintainer approval comment. The template also asks for the model and harness used, and the author states the work was AI-assisted but does not name the model or harness. These gaps are minor. The description is mostly complete.
Explanation
Issue [#31290] requires each queued message to run with the runtime and interaction modes used when it was sent. The PR records both modes on immediate, deferred, queued, fork, and restarted runs. ProviderTurnStartService resolves runtime policy from the run modes. Queued runs do not change the thread modes. The PR adds tests for the reported Plan/Default queue sequence, provider session restarts, steering, and mode-limit checks. The reported Claude transcript also shows queued A running in Plan mode and B running in Default mode.
Explanation
The changes remain connected to [#31290]. Contract fields persist send-time modes. Orchestration changes apply those modes during turn startup and provider session selection. runModes and callerModes update authorization for queued and active runs so mode limits match the modes being executed. MCP changes and the added tests support this behavior. Test fixtures and tracer updates support the changed run-record lookup. No unrelated client or product-area changes are reported.

@coderabbitai On the outside-diff finding for ProviderTurnStartService.ts:703-713: partly addressed in b11007250b. An agent's MCP limits are now the stricter of its run's recorded modes and the thread's current modes, so lowering the thread during a run lowers them right away (test: "lowers a running caller's modes when its thread is lowered mid-run" in threadAccess.test.ts, fails on a15cdb87fa). The side-chat part is unchanged: main already authorizes a first side-chat turn from the thread's full-access mode while provider startup forces approval-required, so aligning the two is a separate fix.
Tip
For best results, initiate chat on the files or code changes.

@juliusmarminge Agreed. I verified the source at b11007250b.
callerModes selects the stricter runtime and interaction modes from the run and the current thread. The named regression test covers a lowered thread with a full-access/default run. This addresses the mid-run MCP limit concern. I inspected the test but did not run it.approval-required for the first side-chat provider turn. That mismatch predates this PR. I agree that aligning those policies is a separate fix, not a blocker introduced here.Would you like me to open a follow-up issue for the side-chat mismatch?

Leaving this for a follow-up rather than this PR. It is not a regression against main: there, a background subagent whose run has ended also takes the thread's current modes, and so did the run itself. This PR makes the run stricter and leaves the subagent where main has it. Closing the gap means recording which run owns each background task. Background tasks don't record that today, and the shell's latestRunId can point at an unheld queued run. The alternative is reading the thread's run history on every MCP call from such a caller. Either way it's new persisted state or a new hot-path read, beyond this fix.
