Problem

t3_queue_reorder rejected a queued correction placed before a delegated-task completion. With a completion backlog, the correction could only run after all earlier completions.

Change

Allow queued messages to be inserted before completion deliveries while retaining the completions’ relative order. An optional run marker records deliberate priority; unmarked legacy queues keep their existing completion-first behavior. Moving a message back clears its priority, and goal-command normalization preserves its existing ordering.

Scope and approval

Fixes #25646

Triaged bug via the automated issue flow; GitCafe mirror #25644.

GitCafe: https://git.cafe/pingdotgg/t3code/issues/25644

Verification

• Original runtime-layer regression fails before the fix with “Queued messages cannot be reordered ahead of automatic completion delivery” and passes afterward.
• Focused queue ordering, runtime lifecycle, steering, delegated completion, projection persistence/recovery, contracts, and goal tests pass. After merging main, queue ordering and runtime lifecycle passed again: 93 tests. The three production files are byte-identical to the audited evidence revision.
• vp run check:changed: passed format, lint, knip, typechecks for 30 packages, and 118 tests in 5 files.
• Independent GPT-6.1 Sol and Claude Opus 5.5 full-diff reviews; independent proof audit rebuilt the evidence and reproduced red/green exits 1/0.

Server runtime fixture	Observed result
Correction moved before C1; C3 arrives afterward	Actual promotions: correction → C1 → C2 → C3 → ordinary message
Attempt to move C2 before C1	Rejected; persisted run records and thread event sequence unchanged
Legacy positions U=1, C1=2, C2=3 with no marker	Actual promotions: C1 → C2 → U

Red original regression · Green original regression · Runtime transcript

Reproduction driver · Reproducible evidence bundle · Evidence report

Visual matrix is empty: no render paths change. Runtime proof uses the real orchestration layer and in-memory SQLite with a stub provider and injected terminal events. It proves queue promotion and persistence, including one starting run at a time, no skipped or duplicate promotions, and empty final queues. Real provider execution, process restart, and UI behavior were not exercised.

Models: GPT-6.1 Sol via Codex and Claude Opus 5.5 via Claude Agent in T3 Code.

Takeover

Taken over in land mode; the production change is unchanged from ad518480c9. origin/main is merged in (head 1d23f502f5). The PR's three tests were replaced with one runtime test that drives the real orchestrator: moves a queued message ahead of queued delegated completions and back. It covers the reorder ahead of a completion, a completion that arrives afterwards, the rejected move of a completion, and clearing priority when the message moves back. The two QueuedRunOrder unit tests were dropped: the legacy completion-first order is already covered by main's existing test in that file.

Evidence

Server-only change: web and mobile hide automatic completion runs from the queue (packages/client-runtime/src/state/threadWorkflows.ts), so no client render path changes and there are no captures. Agents reach the behaviour through the t3_queue MCP tool's reorder action.

Run	Revision	Result
Takeover runtime test, production fix reverted to main	39da8b2458 with Orchestrator.ts and QueuedRunOrder.ts from main	Fails: Queued messages cannot be reordered ahead of automatic completion delivery. (revert-all.log)
Same test, only the priority clear reverted	39da8b2458 with the flag left set on move-back	Fails at the move-back order check (revert-clear.log)
Same test with the fix	39da8b2458	Passes (with-fix.log)
Partial runtime transcript, after only	39da8b2458	Real t3_queue list/reorder/read; orders U,C1,C2,C3,V, C1,U,C2,V, W,V,U,C1,C2; completion moves rejected. Full promotion sequences not captured. (log, driver, index)

Environment: Linux x86_64, Node 26.12.1, Vitest 5.0.5, in-memory SQLite; real orchestrator, event sink and projection store with a stub provider; no real model execution. What else changed: nothing beyond queue ordering. The paired before/after transcript of the fixture matrix was not completed (rows R01–R07, R11–R19, R22 unverified as transcripts).

Verification log

• Review round 1: GPT-6.1 Sol (Codex) MERGE, Claude Opus 5.5 MERGE; no confirmed bugs. Both note that a queued /goal clears a prioritized message's flag, matching main's goal-first order.
• Tests: runtimeLayer.test.ts 1 → 1 (rewritten), QueuedRunOrder.test.ts 2 → 0 added; focused files 91/91 pass; server and contracts typecheck clean.
• vp run check:changed at 1d23f502f5: format, graphql, lint and knip 1/2 pass; the run did not finish on a heavily loaded VM. CI runs the full suite.
• Proof audit pass 1: 17 affected transcript rows; capture incomplete (infra: dependency install took 86 min under load).
• Models: Claude Opus 5.5 (lead, tests, implement, review B) and GPT-6.1 Sol (review A, proof audit, capture), via T3 Code.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — This is a focused server queue-ordering fix with an optional persisted priority field and integration coverage. An unresolved review comment identifies a concrete case where goal-command normalization may clear an existing priority and reverse delivery order, requiring human review.

Walkthrough

Queued messages can now be reordered ahead of automatic completion deliveries. Delivery ordering uses the recorded reorder state while preserving the order of completion deliveries.

Changes: Queued delivery order

Layer / File(s)	Summary
Record queued message reorder state packages/contracts/src/orchestrationV2.ts, apps/server/src/orchestration-v2/Orchestrator.ts	OrchestrationV2Run adds queuedAheadOfCompletions. Queue reordering sets the flag for ordinary runs placed ahead of completions. Goal-command positioning and promotion clear the flag when applicable.
Apply delivery priority and verify ordering apps/server/src/orchestration-v2/QueuedRunOrder.ts, apps/server/src/orchestration-v2/runtimeLayer.test.ts	Delivery ordering prioritizes automatic completions and runs marked queuedAheadOfCompletions. The runtime test checks that a message can move ahead of completions, that completion order is retained, and that completions cannot be directly reordered.

Explanation

Issue #25646 requires a queued message to move ahead of automatic completion deliveries while completion deliveries keep their relative order. The diff removes the rejection for a beforeRunId that names a completion. It preserves all queued runs during reorder, records queuedAheadOfCompletions, and uses that marker with completion priority in queuedRunsInDeliveryOrder. The runtime-layer test covers correction-before-completions, completion order, rejection of direct completion reorder, and moving the correction back. Unmarked legacy runs retain completion-first ordering.

Full details: Out of Scope Changes check

Explanation

The changed production code supports issue #25646. Orchestrator.ts changes reorder handling, marker clearing, and goal-command normalization. QueuedRunOrder.ts consumes the marker. orchestrationV2.ts stores the optional marker. The added runtime-layer test verifies the required behavior. No unrelated production feature or unrelated file appears in the reviewed diff.

Full details: Description check

Explanation

The description includes complete Problem, Change, Scope and approval, Verification, and agent disclosure sections. It provides detailed behavior, test results, limitations, and links to the related issue. However, the Scope and approval section does not include an explicit maintainer approval comment or explain why this focused fix qualifies for the approval exemption.

Resolution

Add the explicit maintainer approval comment and link, or state why this is an obvious, focused bug fix that qualifies without prior approval. Keep the existing issue and verification details unchanged.

Preserve priority when normalizing other messages for a goal command.

If a user reorders correction A ahead of completion C, stopRunForGoalCommand clears A’s flag when another message is promoted as a goal command. queuedRunsInDeliveryOrder then delivers C before A, although the user did not move A back. Keep A’s flag unless normalization actually places A after the completions. This also needs a regression case with an already-prioritized message. (raw.githubusercontent.com)
