When auto compaction fired ("Compacting after being idle…"), Send now on a queued message did nothing. The server rejects steering into a /compact turn, and the client dropped the error silently.

Now Send now during a compaction stops the compaction and sends that message next. This includes a queued /goal. The /goal command already had a "stop the turn, run this next" path, and this reuses it. The button now also shows during a compaction when the provider can't steer. Its web tooltip says "Skip compaction and send this message". The context stays uncompacted when you skip.

A skipped compaction now shows one timeline row, "Context compaction stopped". Before, it also showed a generic "Run interrupted" row that only repeated it. Web and mobile both hide that row for compaction runs.

Compacting, message queuedAfter Send now
Compacting with Send nowOne row per skipped compaction

Proof:

  • Server: a new integration test fails on main with "Wait for context compaction to finish before steering the thread." and passes with the fix. It covers a plain message and /goal.
  • Client: a new client-runtime test, plus new web and mobile timeline tests that fail without the one-row change.
  • Real app: I ran the full flow in a dev server with Claude. A thread with 3 skipped compactions shows 3 "stopped" rows and no "Run interrupted" rows.
  • Mobile: covered by unit tests only.

Walkthrough

Queued-message promotion can stop an active compaction run and send the promoted message next. The client identifies this action, and the web and mobile timelines suppress the associated interrupt result.

Changes: Compaction-time queue promotion

Layer / File(s)Summary
Derive compaction-skip state
packages/client-runtime/src/state/threadWorkflows.ts, packages/client-runtime/src/state/threadWorkflows.test.ts, apps/web/src/components/chat/QueuedRunsControl.tsx
The workflow state identifies when promotion skips compaction and permits promotion in that state. The web tooltip displays “Skip compaction and send this message.”
Reorder and stop the target run
apps/server/src/orchestration-v2/Orchestrator.ts, apps/server/src/orchestration-v2/SteeringCompletion.integration.test.ts
The orchestrator moves the promoted run to position 1 and requests an interrupt for a live compaction run that has not already received a stop request. The shared stop helper accepts a caller-supplied reason. Integration tests check interruption and message order.
Filter compaction interrupt results
apps/web/src/components/chat/MessagesTimeline.logic.ts, apps/web/src/components/chat/MessagesTimeline.logic.test.ts, apps/mobile/src/lib/threadActivity.ts, apps/mobile/src/lib/threadActivity.test.ts
The web timeline and mobile feed omit interrupt results for compaction-command runs. Tests check the resulting timeline and activity group.

Wait for the promoted run before asserting its start.

After the test offers the compaction terminal event, worker.drain() can find no outbox work before the separate terminal-run listener processes that event. The assertions can then observe next still queued and only two started turns. Start a watcher for nextRun entering starting before offering the terminal event, join it, and then drain the worker.

Fixed in 1571e72, but not the way suggested. The queued run already starts in the drain right after the promote, so the fake provider terminal events were never needed. I removed them, which removes the race. Waiting for starting before draining makes the test hang, because the drain is what starts the run.

@t3dotgg You're right. My suggested wait put the dependency in the wrong order: worker.drain() starts the promoted run, so waiting for starting first would hang.

The updated test removes the redundant compaction terminal events and asserts after the promote drain. That removes the race I flagged. I withdraw the finding.

Derive “Send now” per queued command.

When /compact is active, compute the promotion decision for each queued message. Use the contracts package’s parseGoalCommand with that message and the current projection.thread.goal?.status. Return false for non-stopping goal commands, such as /goal show and /goal clear or /goal pause when the goal is not active. Preserve true for ordinary queued messages and goal commands that stop the active run.

Use this per-item decision for the web and mobile label, enablement, and promotion path. Do not use the shared active-message boolean for every queued row.

Declining. After 1571e72, every queued message promoted during a compaction stops the compaction and runs next, /goal commands included. So the shared promoteSkipsCompaction label is accurate for every row. Unsupported goal commands still fail validation before any state changes.

@t3dotgg Understood. My finding incorrectly applied the normal /goal stopping rules to compaction-time promotion. The compaction path stops compaction for every valid promoted message, so the shared promoteSkipsCompaction flag is appropriate. I withdraw the per-item recommendation.

Stop compaction for stop-capable promoted /goal commands.

When goalCommandStopsActiveRun(goalCommand, goal?.status ?? null) permits the promoted /goal to stop the active run, the goalCommand === null guard skips the compaction-stop branch. The goal branch then rejects the /compact target as native maintenance, so the queued command can wait for compaction to finish.

Preserve the native-maintenance guard for other goals:

Note

🤖 Claude Opus 5.5 responding on behalf of Theo

Fixed in 1571e72. Valid: a queued /goal promoted during a compaction only moved to the front. The compaction branch now handles goal commands too. It runs ensureGoalCommandSupported first, then stops the compaction like any other queued message. I took this route instead of the suggested goalCommandStopsActiveRun guard, so that "Send now" always means "skip the compaction". A /goal ship it case in SteeringCompletion.integration.test.ts fails without the change and passes with it.

@t3dotgg The supplied code addresses this finding. The compaction branch now handles promoted /goal commands and calls ensureGoalCommandSupported before reordering the queue or requesting an interrupt. This matches the intended “Send now” behavior without changing the native-maintenance guard for non-compaction targets.

Validate native goal support before changing the queue or requesting an interrupt. Do not gate this compaction-specific behavior on goalCommandStopsActiveRun; that policy still applies to non-compaction goal promotion. Retain the live-run and existing-stop checks before requesting an interrupt.

This suppresses the interruption result whenever the run has a /compact prompt, even if no compaction row exists. Stopping during preparation/provider startup takes Orchestrator.ts's providerTurn === undefined branch, which emits run_interrupt_result with "Run interrupted before provider start" without creating a compaction item. deriveThreadFeedPresentation only replaces the prompt when an actual compaction item exists, so this path now loses its only stopped/interrupted feedback.

Fixed in 6a835f70a2. Valid finding. Web and mobile now hide run_interrupt_result only when the run has both a /compact prompt and a compaction item. That compaction item is what renders "Context compaction stopped". A /compact run stopped before its provider started keeps its interrupted row. New web and mobile tests cover that case, and both fail on the previous head.

Keep the interrupt result when no compaction item exists.

If a /compact run stops before its provider turn starts, the orchestrator emits a run_interrupt_result without a compaction item. This filter removes the stopped event. Mobile then shows the /compact prompt without a stopped row. The web filter in apps/web/src/components/chat/MessagesTimeline.logic.ts at Line 1671 also removes the result and leaves a generic “Context compaction” divider. Suppress the result only when an interrupted compaction item provides the stopped row, or render an explicit stopped row on both surfaces. (raw.githubusercontent.com)

🤖 Claude Opus 5.5 responding on behalf of Theo

Already fixed in 6a835f7. This review ran on 22247f1. Both filters now also require a compaction item for the run, so a /compact run stopped before its provider started keeps its interrupted row. Web and mobile tests cover that case.

@t3dotgg Thanks for clarifying. The supplied mobile code confirms that suppression now requires a compaction item for the same run. Your fix in 6a835f7 addresses this finding.

5Learning: In the TypeScript orchestration code in apps/server/src/orchestration-v2/Orchestrator.ts, run.interrupt and thread.stop use interrupted for user-stopped runs, including runs stopped before provider start. queued-run.cancel instead marks a withdrawn queued run cancelled; an unsent queued run should not supersede restart continuation. The cancelledBeforeStart helper in apps/server/src/orchestration-v2/RestartBackgroundNote.ts does not match interrupted runs, so both restart-continuation precedence checks preserve user interruption.

Suppress the interrupt result only for a stopped compaction.

A completed compaction can be followed by an interrupt result before the provider turn settles. The current filters suppress that result even though the compaction row says “Context compacted.” A still-running compaction is finalized to a stopped status before the provider terminal event, so limit this condition to interrupted or cancelled compaction items in both filters.
