Problem

A steer returned to the durable queue can keep its user timeline item. The transcript then makes the input look delivered while the composer correctly lists its still-queued run.

Fixes https://git.cafe/pingdotgg/t3code/issues/23403.

Change

Hide queued user inputs consistently in shared visibility, SQL snapshots and inherited fork history, including local and inherited row counts. Forks still retain source history after rollback. Restore retained inputs when their run leaves the queue, accepting either startup event order from compatible servers. Before a queued startup fails, republish its retained input so a client whose bounded snapshot omitted it can display the failed prompt too.

The server, shared visibility and client reducer changes repair the same queue-to-transcript lifecycle. Count exclusions preserve upstream's batched shell reads and selected-thread filtering. Scheduling, provider delivery and stable item ordinals are unchanged.

After source rollback, inherited history also preserves cancellation using the run's unchanged attempt. This keeps a cancelled queued input hidden when rollback replaces its run status, while retaining delivered source history.

Scope and approval

This is a focused repair of an obvious state inconsistency: a waiting queued input must not look like a delivered turn. It uses the existing queue and timeline model, adds no configuration or product behavior, and qualifies for the focused obvious-bug exception in CONTRIBUTING.md. The cross-package changes preserve the prompt during startup, cancellation and failure, including bounded history and older compatible servers. The original report came from a personal fork; the regression is checked separately against upstream main.

Verification

• Before applying the production fix, the new client-runtime regression failed on upstream main 3b95e7831b: the queued transition retained item-steer in visibleTurnItems instead of showing only item-reply.
• After applying the fix, the focused shared/client test command passed all 28 tests. The lifecycle regression covers both startup event orders, cancellation and failed startup after a bounded snapshot omitted the queued item.
• On rebased head c7546134faa24f4e78b273dec361081ffefd54b9, vp run check:changed upstream/main passed formatting, lint, both knip stages, GraphQL generation checks, all 28 affected-package typechecks and all 121 selected tests. Server regressions cover completion racing delivery with fake Codex and Claude providers and retained-input republishing before queued startup failure. SQL coverage includes bounded snapshots, runless inputs and upstream's batched shell-count tests. An existing unused layerUnavailable warning and existing Effect suggestions remain outside this change.
• The inherited-history regression failed before its production fix with the held input in the fork prefix. It now passes for queued and cancelled inputs, before and after source rollback, covering projections, activity pages, inherited counts and filled-page row positions.
• The same regression checks source and fork shells through both shell APIs. Before the local count fix it failed with a shell count of two while the source projection contained one item. Both count exclusions are retained in upstream's new batched query structure after the rebase.
• The test-only follow-up on a51b33cfa5ea6a08bd493042ccf5cd38e46333c8 adds a completed queued_turn input to the inherited-history regression. It must remain visible and counted while queued/cancelled inputs stay hidden. vp run check:changed c7546134faa24f4e78b273dec361081ffefd54b9 passed formatting, lint, both Knip stages, GraphQL, both affected-package typechecks and all 37 ProjectionStore tests. Independent review found no actionable issues.
• All required upstream checks passed on a51b33cfa5ea6a08bd493042ccf5cd38e46333c8, and CodeRabbit completed with no actionable comments. The additional Labs run on this exact head was cancelled: Quality and server shards 2/3 passed, while another runner logged a shutdown. The documented Blacksmith retry was rejected by GitHub with HTTP 422, “Actions has been disabled for this repository.” No test failure was reported in that run. Full Labs checks passed on the preceding production head c7546134faa24f4e78b273dec361081ffefd54b9; the subsequent change is test-only.
• On current head 3ebddb5160f0e94ca7d94d09e911431ffb9a40e9, the rollback regression also cancels and rolls back the held run. It failed before the correction with the undelivered input in the fork. Afterward, vp run check:changed a51b33cfa5ea6a08bd493042ccf5cd38e46333c8 passed formatting, lint, both Knip stages, GraphQL, both affected-package typechecks and all 37 ProjectionStore tests. Independent review checked this correction clean, including attempt lifecycle, SQL null handling and indexes. Full fork checks passed on this exact commit, with the full source SHA verified in checkout logs. Required upstream checks passed, and CodeRabbit's requested review completed with no actionable comments on this head.
• Independent GPT-6.1 Sol review checked c7e3993fe9..c7546134fa and found no actionable findings, including the batch-query conflict resolutions. The initial contribution-triage dry run found this eligible for deeper review under the focused obvious-bug exception. This does not claim maintainer approval.

No new live desktop, browser or mobile reproduction was run. The proof is a logic/state regression with fake providers, shared visibility, SQL snapshots and the shared web/mobile reducer; no component layout is changed.

Explanation

Issue #23403 requires queued inputs to stay hidden from delivered timeline views, restoration when the run leaves the queue, and prompt visibility when queued startup fails. The shared visibility rule hides queued and cancelled queued-turn inputs. SQL snapshots, inherited history, and local and inherited counts apply the same exclusions. The client projection restores retained inputs for either startup event order and preserves bounded-snapshot behavior. The server republishes retained inputs before queued-start failure. Reported tests cover delivery, cancellation, startup failure, bounded history, fork rollback, counts, and completed queued-turn inputs.

Full details: Out of Scope Changes check

Explanation

The production changes implement the queued-input lifecycle in issue #23403. Inherited-history and count changes preserve the same visibility rule after fork creation and source rollback. Client, server, shared, SQL, and provider tests support this behavior. The completed queued-turn fixture verifies the required visible boundary. No unrelated configuration, scheduling, provider-delivery, or item-ordinal behavior is demonstrated.

Exclude queued items from forked history.

If a held queued run precedes a completed fork-source run, visibleTurnItemsThroughRun copies the queued run’s retained user item into the fork. This path checks for superseded interrupts but does not apply the queued-item visibility rule. readTimelineIndex repeats the omission at Line 5364, so fork timeline reads can also show the prompt as delivered. Apply the shared visibility rule when building both inherited prefixes; account for the same exclusion in inherited item counts.

Confirmed and fixed in 6632491. Both inherited prefixes now exclude queued and cancelled queued-turn inputs. The SQL window and inherited shell counts apply the same exclusion while preserving source history after rollback.

The new regression, "keeps undelivered queued input out of forks taken after a later run", failed before the production change with the held message in the inherited prefix. It passes after the fix and covers full projections, activity pages, both shell APIs and local row positions through the filled-page count path, for queued and cancelled inputs before and after source rollback.

Final vp run check:changed upstream/main passed formatting, lint, both knip stages, GraphQL, all 28 affected-package typechecks and all 119 selected tests, including all 35 ProjectionStore tests. Full fork checks are running on this exact commit: https://github.com/Alb11747/t3code/actions/runs/39748420426.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Exclude held queued-turn inputs from SQL shell counts.

The SQL item_count aggregation includes queued-turn user messages from queued or cancelled runs. The shared visibility predicate excludes those items. For non-fork SQL shells, row.item_count becomes state.itemCount, and visibleItemCountForShell returns that value. Both shell counts can therefore exceed the projection count by the held item.

Apply the same exclusion used for inherited run counts:

Fixed the local shell count discrepancy in 6503a7e. The SQL sum now subtracts queued-turn user items only for queued or cancelled runs, matching inherited counts while preserving the existing rollback and runless behavior.

The extended regression failed before the fix with a shell count of two versus one visible source item. It now checks both source and fork projections against both shell APIs, for queued and cancelled inputs before and after source rollback. vp run check:changed 6632491fc39c099589269806de7ac75de89eb9a1 passed formatting, lint, both knip stages, GraphQL, both affected-package typechecks and all 35 ProjectionStore tests.

Add a delivered queued_turn message to the answered run. The fixtures do not separate status filtering from intent filtering.

The only queued_turn item sits in the queued or cancelled run. The only item in the completed run uses turn_start. A filter on inputIntent === "queued_turn" alone would give the same result in every assertion. The SQL window, the shell counts, and the shared predicate all depend on the status check. A steer that was delivered keeps queued_turn in a completed run. It must stay visible and counted, but no assertion covers it.

Add a queued_turn user message to answeredRunId. Then expect it between answered and fork. The shell counts and the turn-limited window will cover the status condition as well.

🧪 Proposed fixture and assertion change

         yield* applyUserItem({
           threadId: sourceThreadId,
           runId: answeredRunId,
           ordinal: 200,
           text: "answered",
           inputIntent: "turn_start",
         });
+        // A delivered steer keeps `queued_turn` in a run that left the queue.
+        yield* applyUserItem({
+          threadId: sourceThreadId,
+          runId: answeredRunId,
+          ordinal: 201,
+          text: "delivered steer",
+          inputIntent: "queued_turn",
+        });

-              .slice(0, 2)
+              .slice(0, 3)
               .map((row) => (row.item.type === "user_message" ? row.item.text : row.item.type)),
-            ["answered", "fork"],
+            ["answered", "delivered steer", "fork"],

Based on learnings: a test for a filtered query must include a record that matches a similar but different condition and assert that it is preserved.

Added the completed-run queued-turn fixture in a51b33c. The regression now requires the delivered input to remain between the answered message and the fork marker, while still excluding queued and cancelled inputs. Its activity-page, source/fork shell-count and filled-page position assertions cover this distinction before and after source rollback.

vp run check:changed c7546134faa24f4e78b273dec361081ffefd54b9 passed formatting, lint, both Knip stages, GraphQL, both affected-package typechecks and all 37 ProjectionStore tests. Independent review found no actionable issues. This follow-up changes only the test.

[Alb11747]

Final review found one more inherited-history transition: rollback changes a cancelled run to rolled_back, which could reveal its previously hidden queued input in an existing fork. Fixed in 3ebddb5 by preserving the cancellation rule using the unchanged cancelled attempt in the inherited projection, SQL window and shell counts. Delivered source history still survives rollback.

The extended regression failed before the fix with the held input visible. It now passes after rolling back both the answered source run and the cancelled held run, covering projections, activity pages, both shell APIs and filled-page positions. Removing either SQL correction makes a distinct assertion fail. vp run check:changed a51b33cfa5ea6a08bd493042ccf5cd38e46333c8 passed formatting, lint, both Knip stages, GraphQL, both affected-package typechecks and all 37 ProjectionStore tests.

The Release Smoke job failed at node --test .github/scripts/relay-state-output.test.cjs: “rejects missing JSON” returns exit code 0 where the test expects failure. I reproduced this locally on commit 0912598 with Node 26.12.1. The test, its inline step in .github/workflows/release.yml, and scripts/release-smoke.ts are unchanged from upstream main (d2c2595); none is in this PR’s diff, so this failure is not caused by the queued-steer changes.

Evidence

Deliver the first prompt, then stage a distinct new steer through genuine native rejection and retain it in the queue. Remove its temporary provider through Settings, click Send now, wait for startup failure, reload, and wait for synchronization to finish. Both builds preserve the original delivered prompt and answer. The base hides the new failed prompt; the head shows it once immediately above its failure.

Environment for both sides: independent fresh server databases, Chromium 1280×800, DPR 2, light theme. Identical transcript crops exclude operational metadata. Each final still matched a second capture taken more than 500 ms apart with zero pixel differences.

The actual runtime transcript and structured responses show the queued steer leaking into base thread-read and bounded history, with shell counts 6 versus 5. A fork after a later completed turn leaks the still-undelivered steer on base, with inherited counts 10 versus 9. Head preserves both delivered exchanges. Successful starts display the new prompt once on both builds. Read-only database inspection confirms the held input remains pending with no provider turn or delivery timestamps. The head database installs migration 086's partial index and SQLite selects it for the queued-input predicate.

Reproduction artifacts: driver, transport relay, setup and capture procedure.
