Merged origin/main into the branch with a merge commit. The only conflict was in ClaudeAdapterV2.ts: main's #34563 (d6e5f2e) added the same applySelectionLive helper this branch had added, differing only in a parameter name, so I kept main's version and the adapter has one copy. openQuery, main's new applyModelSelection (live effort-only changes; model changes still wait for the next turn) and this branch's steerTurn all use it. The paths do not overlap: a model change sent with a steer is still applied by steerTurn before its final active-turn check, with the orchestrator forwarding the user's selection on the steer effect. EffectOutbox, EffectWorker, Orchestrator, ProviderTurnControlService and ProviderAdapter merged without conflicts.

Fixes #34549

Reproduction on main

Commit 836b86a (origin/main). Started T3CODE_DEV_SEED=0 vp run dev in a fresh worktree, paired the web client in the preview browser, and used the real Claude provider. Run 3 started on Claude Sonnet 5.5 and ran a project script four times (about 25s each, about 2 min total). While it ran, I switched the composer model picker to Claude Haiku 5.5 and sent 'what is your exact model id right now?'. The send went in as a Steer, and the picker kept showing 'Haiku 5.5 Medium'. The agent replied 'My exact model id is claude-sonnet-5-5' and kept going on Sonnet. The steered message got no model-switch divider or note. Database: run 3 has modelSelection claude-sonnet-5-5 and finished on it. After run 3 completed, a plain follow-up started run 4 with the divider 'Sonnet 5.5 High → Haiku 5.5 Medium', and the agent replied 'claude-haiku-5-5'. So the new model applies on the next turn, and only then does the UI show the switch. I did not reproduce the reporter's cancelled, never-started runs (ordinals 2-7): my steer created no extra run.

Evidence

Started a running Claude turn, changed the composer from Model A to Model B, and sent “what is your exact model id right now?” using Steer. Base answered as Model A despite showing Model B; head answered as Model B.

Environment: real web app and Claude provider, light theme, 1280×800 viewport, separate fresh databases. Privacy redactions replace identifiers with Model A (initial) and Model B (requested). Recordings are sampled at 2 fps.

Not in this change

• A steered selection the live Claude process cannot apply (thinking toggled, effort cleared, or a model change after the session's starting permission mode changed) is still deferred to the next turn with no UI indication that the switch is pending.
• Codex also plans apply_on_next_turn and its turn/steer takes no model, so a Codex steer with a model change likely has the same mismatch; it was not changed here.
• The run's recorded modelSelection still shows the selection the turn started with after a steer switches the live model (executedModel comes from what Claude reports).
• A steered selection the live Claude process cannot apply (thinking toggled, effort cleared, or a model change after the session's starting permission mode changed) still waits for the next turn with no UI indication that the switch is pending.
• Codex also plans apply_on_next_turn and its turn/steer takes no model, so a Codex steer with a model change likely has the same mismatch; it was not changed.

After a model-changing steer, later messages use the turn-start prompt effort instead of the active selection's effort. applySelectionLive updates existing.selection, but a subsequent steer requesting that same selection leaves liveSteerSelection undefined, so this fallback recompiles currentTurn.input.modelSelection and can restore Ultrathink: after switching to ordinary effort.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — Claude now applies compatible model selections sent with a steer to the running turn. An unresolved review concern remains that later steers can restore the original effort instruction instead of preserving the active selection.

Walkthrough

Steer requests can carry a model selection through orchestration to ClaudeAdapterV2. The adapter applies eligible selections to a running turn before offering the steer. Tests cover model changes, reverted selections, and a turn ending during selection application.

Changes: Live steering selection

Layer / File(s)	Summary
Carry model selection through steering packages/provider-core/src/server/ProviderAdapter.ts, apps/server/src/orchestration-v2/EffectOutbox.ts, apps/server/src/orchestration-v2/Orchestrator.ts, apps/server/src/orchestration-v2/EffectWorker.ts, apps/server/src/orchestration-v2/ProviderTurnControlService.ts, apps/server/src/orchestration-v2/runtimeLayer.test.ts	Steer request types accept an optional modelSelection. Active steering forwards it through the effect worker and control service. Delegated completions and notifications do not carry the selection. The runtime-layer test checks that the active run’s selection is included.
Apply selection during a Claude steer apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.ts	ClaudeAdapterV2 applies eligible live selections through applySelectionLive. It selects the prompt-effort prefix from the eligible selection and checks that the turn and query remain active before offering the steer.
Validate live selection and turn-end behavior apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.test.ts, apps/server/src/orchestration-v2/SteeringCompletion.integration.test.ts	Adapter tests cover a model change and a turn ending during selection application. Integration tests verify selections passed across successive steers, including reverted selections.

Merge Risk: Low · up to ec23b

Live model switching for Claude steers works as intended. Two edge cases remain: a steer recovered after its turn completes can run on a later model selection, and context-usage figures can report the original model's capacity after a live switch. Neither blocks the primary fix, but both are worth addressing.

Full details: Title check

Explanation

The title names the main change: a model change sent with a Claude steer now applies to the running turn. The changeset adds modelSelection to the steer path and applies it live in ClaudeAdapterV2.steerTurn. The title uses a conventional commit prefix and plain language. It is 84 characters, which is longer than ideal but still clear.

Full details: Linked Issues check

Explanation

[#34549] The issue requires that a model change sent during a running Claude turn either applies to that turn, or the UI states it applies from the next turn. At head, ClaudeAdapterV2.steerTurn computes steerSelection from turnInput.modelSelection and sets liveSteerSelection when the query identity differs, canApplyClaudeSelectionLive passes, and either the API model is unchanged or the permission mode matches. It then calls applySelectionLive before the active-turn and query check. The PR description reports a live reproduction: on base the agent reported the old model while the picker showed the new one, and on head the steered answer reported the selected model during the same turn. The Orchestrator and EffectOutbox/EffectWorker/ProviderTurnControlService plumbing forwards the steer's selection. Limits: selections the live process cannot apply (thinking toggled, effort cleared, permission-mode change) still defer to the next turn with no UI indication. The issue's 'or the UI says so' branch is therefore not met for those cases. The PR states this gap. The core requirement is met for live-applicable selections.

Full details: Description check

Explanation

The description follows the repository template closely enough to pass. It has a clear problem statement with a linked issue (#34549), a detailed change explanation (merge resolution plus steerTurn model-selection handling), a substantial verification section with reproduction steps on main, before/after evidence, stated test results, and explicit limitations. The Scope and approval section is the weakest part: it links issue #34549 but does not explicitly show a triaged maintainer approval comment, which the template asks for. The description also repeats the 'Not in this change' bullets twice and the 'AI-assisted' line appears twice, which is a minor editorial issue. The template also asks for the model and harness used when an agent did the work; the description says 'AI-assisted' but does not name the model and harness. These gaps are non-critical, so the check passes.

Full details: Out of Scope Changes check

Explanation

The whole-PR diff (merge base 6464729 to head ec23b66) for ClaudeAdapterV2.ts contains hunks unrelated to the model-selection steer fix and not described in the PR. (1) In the Stop/interrupted path, a new block emits a 'system_notice' titled 'Steer delivery not confirmed' for each dropped steer whose liveQuery has promptEchoMode 'early' or 'result_only'. This changes user-visible steer-delivery reporting and is not part of the model-selection fix for #34549. (2) In the query message handler, a new call to completeProviderRetry runs on stream_event message_start. This changes provider retry handling and is not connected to model selection or steers. The PR description covers only the selection forwarding, live apply, and a test expectation update. The steersClosed flag and the pendingSteers record shape support the steer race ordering and are plausibly related. The two hunks above are not shown to serve #34549. The applyModelSelection method added to the adapter surface is a separate path (not a steer) and the PR does not explain it; it is also unconnected to the stated fix.

Resolution

Remove the unread-steer 'system_notice' block and the message_start completeProviderRetry call from ClaudeAdapterV2.ts, or move them to a separate PR with its own linked issue and tests. Explain in this PR, or remove, the applyModelSelection adapter method if it is not required for the steer path. Re-run apps/server tests for ClaudeAdapterV2 and runtimeLayer after the change.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Preserve the steer’s selection in the follow-up.

If a steer with selection B reaches an ended turn after a later steer has changed the thread selection to C, this fallback omits B. dispatchMessage then uses the thread’s current selection C, so the earlier message runs with the wrong model. Forward effect.request.modelSelection for ordinary steer follow-ups.

Steers after a live selection change can use the original effort prefix.

When a steer requests the selection that the live process already runs, liveSteerSelection is undefined. The prompt prefix then falls back to currentTurn.input.modelSelection, which is the original turn selection. If the effort prefix differs between the original and applied selections, the second steer can send the original effort instruction after the live effort has changed.

Derive the fallback from the selection applied to the live query, not from the original turn input. Extend the adapter regression test with a second steer that requests the same selection, and assert the effort prefix in that steer.

apps/server/src/orchestration-v2/EffectWorker.ts:316-318
Minor · Data Integrity & Integration · Quick win

Preserve the submitted selection when a completed steer is recovered.

Direct steer delivery forwards effect.request.modelSelection (EffectWorker.ts:260-262). The completed-turn fallback forwards a selection only for delegated messages (EffectWorker.ts:316-318). An ordinary recovered follow-up therefore dispatches without modelSelection. Orchestrator.ts:6290 then uses projection.thread.modelSelection. If a later steer already changed the thread selection, the recovered message runs on that later model rather than the one it was submitted with.

Forward the request's selection to the recovered ordinary message. Keep the delegated behavior unchanged.

Suggested fix

-                        ...(message.delegatedCompletion === undefined
-                          ? {}

Use the effective live selection for context-usage limits.

When a steer applies a model with a different context window, applySelectionLive updates only existing.selection. emitContextUsage still computes maxTokens from context.input.modelSelection. Later usage events for that turn can therefore report the original model's capacity. The compaction threshold, which claudeAutoCompactThreshold derives from maxTokens, uses the same capacity. context.autoCompactWindow is also resolved once from the original turnInput.modelSelection.

Record the applied steer selection on the active turn context when steerTurn applies it. Then derive maxTokens and the auto-compact window from that value in emitContextUsage. Keep the recorded run modelSelection unchanged. Extend the existing model-switch regression test to assert the context-usage event that follows the steer.
