fix(server): allow queued messages ahead of completion deliveries - #25697
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.
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.
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 from @juliusmarminge's original. The reorder change and the optional queuedAheadOfCompletions marker are unchanged. origin/main is merged in (twice this round). Main's new compaction-skip branch of promote-to-steer interacted with the marker, and review found three ordering bugs there, now fixed:
A goal promoted into a compaction drops its own priority, like a goal promoted into an ordinary turn, so completions still go first.
A plain message sent into a compaction leaves other messages' priority alone. Only a goal resets it.
When a queued command goes first, completions are renumbered together with messages, so a prioritized message cannot tie with a completion on position and lose.
The PR's three original tests became one runtime test, moves a queued message ahead of queued delegated completions and back. Main's compaction test in SteeringCompletion.integration.test.ts now also covers a message moved ahead of a completion.
Evidence
Server-only change. Web and mobile hide automatic completion runs from the queue (packages/client-runtime/src/state/threadWorkflows.ts), so no render path changes and there are no screenshots. Agents reach the behaviour through the t3_queue MCP tool's reorder and promote_to_steer actions. The evidence is paired runtime transcripts: one driver, run before at 3d369d5596 (merge-base) and after at f6290eb6d3. It drives the real orchestrator, event sink, projection store and t3_queue handler. The final head adds only a test type fix and a main merge that does not touch queue code.
C = completion, U/V/W/S = messages, G = goal, A/P = active/earlier turn. Start order = order in which runs actually reached the provider.
The sheets hold the raw before/after transcripts, the zero-threshold diff -u (Diff0) and the unexpected-difference check (DiffT). Their after column was captured at a77de508c2, except R07, which has its own sheet at f6290eb6d3. The ef3571 rerun and f6290eb rerun (all 20 variants pass: log) update the after side: only R07 start orders change (R07-ordinary a77→ef3571, ef3571→f6290eb, where every delivery and start order is identical).
Environment: Linux x86_64, Node 26.13.0, Vitest 5.0.5, in-memory SQLite, frozen clock, fake Codex provider; no model execution, process restart or client. What else changed: persisted queuedAheadOfCompletions true/false on queued runs; completions get new queue positions when a queued command goes first (their order is unchanged); event and receipt sequence numbers shift with the extra run.updated events. Driver and scripts: driver at head, original driver, reproduce.sh, index, bundle.
Verification log
Review round 1 at 2c6faf415b: GPT-6.1 Sol FIX_FIRST: a goal promoted into a compaction kept its priority. Fixed in a77de508c2. Claude Opus 5.5 MERGE.
Review round 2 at a77de508c2: GPT-6.1 Sol FIX_FIRST: a plain message sent into a compaction demoted other prioritized messages. Fixed in ef3571a1e4. Claude Opus 5.5 MERGE. It also judged CodeRabbit's suggestion on Orchestrator.ts (keep flags on unmoved messages when no completion is queued) a false positive: keeping them would make later completions reverse the user's chosen order.
Review round 3 at ef3571a1e4: both reviewers found the same bug: completions kept stale positions while messages were renumbered, so a prioritized message could tie with a completion and lose. Fixed in f6290eb6d3; GPT-6.1 Sol's reproduction fails at ef3571a1e4 and passes at f6290eb6d3 (red, green). Three review rounds were run; the round-3 fix had no fourth review.
Tests: runtimeLayer.test.ts +1 (reorder ahead of completions and back; fails on main). The compaction-promote case in SteeringCompletion.integration.test.ts was extended, not added: it fails when any one of the three fixes above is reverted. Focused files 143/143. vp run check:changed at f6290eb6d3 plus the type fix: format, lint, knip, typecheck (36 packages), 7 test files. All pass.
Proof audit: pass 1 derived 9 rows and 20 variants. Pass 2 rebuilt all 40 before and after transcripts with a 0-byte delta, and found every row sufficient except R07's stale descriptions. Those were replaced with the head sheet above, and two re-checks rated R07 sufficient. Final verdict: SUFFICIENT.
CodeRabbit:
Compaction test (on a77de508c2): covered at head. The plain variant now asserts the completion starts after the reordered correction.
Completion renumbering: fixed in f6290eb6d3.
Keep flags when no completion is queued: answered under round 2.
CI: all 32 checks green on 8b13a4db8c.
Not exercised: real provider CLIs, process restart, web or mobile clients.
Models: Claude Opus 5.5 (lead, review B) and GPT-6.1 Sol (review A, proof audit, capture), via T3 Code.
Reordering a queued message before an automatic completion delivery was
rejected, and delivery order forced every completion first regardless of
queue position.
Delivery order now follows queuePosition, with completions winning ties.
A new completion takes the position of the last queued completion (or the
queue head), so by default it still runs before visible messages and after
earlier completions. The reorder handler treats completions like any other
queued run as a target while still refusing to move them.
Fixes#25644

… completions
Delivering by queuePosition alone silently reordered queues stored before the
upgrade: a completion queued behind visible messages (U@1 C@2) used to run
first and would now run last. Positions cannot tell that legacy shape apart
from a user reorder, and widening them past PositiveInt would break older
clients' decoding.
Delivery keeps the completions-first rule. A reorder that places a message
before a queued completion marks it queuedAheadOfCompletions, which puts it
in the completions' priority band by position. Goal normalization clears the
mark, and new completions keep their max+1 position, so they land after
earlier completions and after messages the user moved ahead.

Macroscope's review found this PR requires human approval — Queued messages can now be explicitly placed ahead of automatic completions. An unresolved concern remains over whether promoting another goal should erase that ordering, potentially delivering a completion before the user's correction.

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, apps/server/src/orchestration-v2/SteeringCompletion.integration.test.ts
Delivery ordering prioritizes automatic completions and runs marked queuedAheadOfCompletions. Tests check that a message can move ahead of completions, completion order is retained, and promotion during compaction preserves the expected run order.
During compaction, promoting another message can undo a deliberate queue ordering.

Explanation
Issue #25646 requires queued messages to move ahead of automatic completion deliveries without changing the deliveries’ relative order. Orchestrator.ts now accepts the reorder and marks non-completion runs placed before the last completion. QueuedRunOrder.ts uses that marker while retaining queue-position ordering, so completion order stays intact. Goal-command paths clear the marker. The runtime and compaction tests cover reordering, a later completion, rejected completion reordering, move-back, and goal behavior.

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)

…tions
Replace the PR's tests with the takeover's minimum: one runtime test that
drives the real orchestrator. A queued message reordered ahead of two queued
delegated completions runs first, the completions keep their order and a
later completion queues behind it; completion runs still cannot be
reordered; moving the message to the end clears its priority so a plain
follow-up runs before it. Legacy completion-first order stays covered by the
existing QueuedRunOrder unit test, so the PR's two unit tests are dropped.

Assert delegated completion survival and delivery after promotion.
In the promoted === "next" case, the current started assertion also passes if the delegated completion is dropped. The test does not inspect the queue after promotion or resume the queue after the promoted run completes. Add assertions that the completion remains queued and is subsequently started. No inspected related test covers this combined path.
