ELI5

When Codex asks several questions at once, the chat showed them in a scrambled order. Now every structured chat row sits where the chat's own record put it, so the questions read in the order Codex asked them.

What Changed

Before: in a structured Codex chat, answering the first of three questions moved the "Awaiting user input: 2 questions" row above the answered first question. Once all three were answered they read newest first, and a cancelled ask came out in yet another order.

After: the answered, cancelled and still-waiting rows of one ask always read in the order Codex asked them, at the ask's place in the transcript.

Mechanism: a structured chat is backed by a journal on the host. Each journal write gets a sequence number, and the journal's contract is that the sequence orders the timeline; the timestamp is the provider's clock and can run backwards. The desktop list ignored that and sorted rows by timestamp, breaking ties by row id. Codex writes every question of one ask in a single write, so they shared a timestamp and were ordered alphabetically by the question ids the model made up (for example scope, priority, deadline).

Rows projected from the journal now carry their journal position: the sequence of the write that created the item, then the item's place within that write. The host records that place when it folds a batch, keeps it when a later write revises the item (as it already did for the sequence), and sends it with each item as a new optional field. The desktop list and the host's conversation outline sort journal rows by that position and nothing else.

Rows that are not in the journal keep their existing rules. The streaming preview and the pending/launch rows are still separated by rank. A send still waiting in the outbox sorts after every journal row, since it was made after everything the journal holds, and sends among themselves sort by time. A send the host journalled and then refused is still drawn from the outbox (it waits there for Retry), but it keeps the place the journal recorded for it, so it does not drop below what the agent wrote afterwards; its Retry bar stays next to the composer as before. That covers a send whose agent could not be started: the host records the message first and only then starts the agent, so the "could not restart" line is written after the message and is drawn below it. Terminal-backed chats have no journal, so they keep exactly the old time-then-id order.

Why

Ordering by time was the bug class, not only the tie-break. Besides same-write ties, a row the host journals while recovering from a crash carries the provider's earlier clock at a later sequence, so the time sort drew it above rows that were written before it. The host's own snapshot already orders by sequence and has a test for that case; only the client re-sorted by time. Ordering by position removes both cases for every row kind (questions, approvals, messages, tool rows) instead of patching the tie-break.

The place within a write is recorded explicitly rather than read from array order. Keeping the order the rows arrived in happens to give the right answer today, but only because every step between the journal and the list preserves array order; the client's reducer, paging and batch merge now sort by the same explicit position, so no step can reorder it.

An outbox send sorts after journal rows instead of by its local timestamp. It has not reached the journal, so when it is sent it will land after everything the journal holds; drawing it there now means it does not jump when it lands, and a composer clock that trails the host's (for example on an SSH host) can no longer draw an unsent message above the agent's newer rows. Comparing an unsent message to journal rows by time instead would mix two orders that can disagree, so the list would have no single consistent order. When a send needs Orca to restart the agent and the restart fails, the order is: the message, then the "could not restart" line, then the Retry bar by the composer. The host records the message before it tries the restart, so the failure is always written after the message.

The alternative was to show one row per Codex ask, listing its questions with their answers. That also fixes the order for questions, but only because one ask would no longer produce several rows, and it leaves time-based ordering in place for everything else. It is a presentation change worth considering on its own.

Not changed here: the "Awaiting user input" list still folds after each answer, because the waiting group is keyed by its first unanswered question, which changes when that question is answered.

Linked Issue

None. Found during live QA of #23451.

Visual Proof

Checked live against real Codex (0.157) in a background dev build on a Mac with an isolated profile. A default structured Codex chat cannot ask questions (Codex offers its question tool only in Plan mode), so each run started Codex with its own default_mode_request_user_input feature on, through a wrapper for that run only. In both runs, Codex listed its three questions in an order that differs from the alphabetical order of their ids, so an id sort shows up.

Before (main): answered questions came out newest first (Q3, Q2, Q1), and after answering Q1 the waiting row sat above it:

After: answering Q1 leaves it above the waiting row for Q2 and Q3:

After: all three answered read Q1, Q2, Q3, and stay that way after a reload:

After: a cancelled ask reads Q1, Q2, Q3 (checked twice, and after reloads):

A follow-up sent while Codex is still working appears once and never moves (sampled every 150 ms), both while pending and after Codex accepts it:

Testing

• src/main/codex/codex-structured-question-order.test.ts drives a real Codex three-question ask through the real host journal, the answer and cancel paths, the client session reducer and the transcript projection. It reproduces all three live orders on main (waiting group above the answered question; answered rows newest first; cancelled rows second, first, third) and passes with the fix.

• New structured-agent-session-transcript-order.test.ts: a row recovered after a crash, with an earlier timestamp than the rows journalled before it, sorts by sequence in both the desktop list and the host outline; the three answered questions of one write sort by their place in it even when handed over shuffled and with ids that sort differently; an outbox send sorts after journal rows even when its timestamp is older; a send the provider refused stays at its journal place above the agent's later reply, while a newer unsent message still sorts last.

• Restart failure order, through the real host, journal and chat projection: a start the host could not make (structured-agent-session-accept-then-deliver.test.ts, "draws the messages it failed above the error row, since they were accepted first") and a restarted agent that exits before it finishes starting (structured-agent-session-send-restarts-failed-start.test.ts) both draw the accepted message above the failure line. With the refused send's journal place removed, both fail with the failure line drawn above the message.

• Worker transcript bounds: a structured worker's journal rows come back from worker-read and the saved worker archive without the list position.

• Host reducer: a batch's items record their place in the write, and a later revision keeps it. Client reducer: a history page and a live batch with one write's items shuffled come out in position order.

• The outline parity test's recovered row now sits where it was journalled (it previously asserted the time order).

• Ablation, one change reverted at a time with the tests kept: time-based list sort (end-to-end and new transcript tests fail), place-in-write not recorded or not kept on revision (host reducer test fails), client reducer sorting by sequence only (client reducer test fails), outbox rows sorted by time (outbox test fails), a refused send without its journal place (refused-send test fails), worker reads keeping the position (worker bound test fails). Keeping arrival order for rows that share a timestamp, this PR's earlier approach, still passes the end-to-end test but fails the recovered-row and shuffled-write tests. Each passes again when restored.

• On the branch merged with current main: native-chat renderer, src/shared, native-chat main (journal and agent-session wire), Codex and worker transcript suites pass, plus mobile session tests and mobile typecheck, pnpm tc, check:code-quality:changed, check:react-doctor:changed and oxlint on the touched files.

• config/tsconfig.node.json lists the two renderer question-projection files the main-side end-to-end test imports.

Notes

Wire: the host adds one optional field to each journal item (its place within the write, omitted when zero). Older clients ignore it and keep sorting by time. A newer client paired with an older host reads the field as absent, so rows of one write tie on position and keep the order the host sent them, which is journal order; it still fixes the crash-recovery case, since the sequence is already on the wire. The position on a transcript row is set by the structured projection. The desktop and mobile lists and the host outline use it; the structured worker read and the saved worker archive run the same projection, so the worker transcript bound drops it and neither returns nor stores it. Terminal-backed chat messages never carry it. Nothing persisted changes: the place in a write is re-derived from the stored batch on every replay.

The host's conversation outline (the message rail's list of older user messages) now orders by journal position too. An older client showing a newer host's outline gets the journal order for the not-yet-loaded part while its loaded rows still sort by time, so the two could disagree only for a crash-recovered user message; the loaded rows replace the outline entries as they load. Mobile draws journal items in the order the shared client reducer keeps them, which now uses the same position, and does not re-sort by time; it already drew one row per question in journal order, so it looks the same. No platform-specific code.

• Tie-preserving transcript projection — projectNativeChatTranscriptMessages now defaults to the new time-only compareNativeChatMessageTimes, so rows that share a timestamp keep the order their source supplied instead of falling back to row id (src/shared/native-chat-transcript-projection.ts:12).
• List uses the tie-preserving comparator — the message list projection passes compareMessageTimes (rank, then time) rather than the id-breaking compareMessages (native-chat-message-list-projection.ts:28).
• Total order kept for unordered sources — compareMessages is rebuilt as compareMessageTimes || compareNativeChatMessagesByTime, preserving the previous rank → time → id total order for the terminal-backed merge and orderNativeChatMessages (native-chat-session-assembler.ts:120).
• Host-journal integration test — a real Codex three-question ask is driven through the host journal, answer and cancel paths, the client reducer and the list projection, reproducing all three live orderings (src/main/codex/codex-structured-question-order.test.ts).
• List-projection tie test and tsconfig include — a new equal-timestamp ordering case, plus the two renderer files the new main-side test imports added to the node tsconfig.

I re-ran the three touched test files, the adjacent grouping/question/outline suites, pnpm tc:node and oxlint on the changed files — all pass. Reverting the comparator changes makes the four new ordering assertions fail, so the tests genuinely pin the behavior. agent-session-conversation-outline.ts is the only default-comparator caller and passes journal order, and mobile doesn't consume either changed projection, so the shared default change is safe.

• Rename only since the prior review — cf8ecbc renames the time-then-id total order from compareNativeChatMessagesByTime to compareNativeChatMessagesByTimeThenId, so it no longer reads as if it compared time alone (src/shared/native-chat-transcript-projection.ts:19).
• Call sites updated — compareMessages in the session assembler now calls compareNativeChatMessagesByTimeThenId; no references to the old name remain (native-chat-session-assembler.ts:121).
• The functional fix from c577f02 (time-only default comparator, list uses compareMessageTimes, host-journal integration test, tsconfig includes) is unchanged.

Verified at the new head: no remaining references to the old symbol, pnpm tc:node passes, and the codex question-order, list-projection, message-grouping and rail-outline-parity suites all pass.

Review status: ready for review

Head: cf8ecbc53c. CI: 27 passed, 12 skipped, 0 failed.

What this fixes. When Codex asked several questions at once in a structured chat, the rows came out scrambled:

• answered questions newest first (Q3, Q2, Q1)
• cancelled ones in another order (Q2, Q1, Q3)
• after answering Q1, the waiting row for the rest sat above it

Codex writes all questions of one ask in a single journal write, so they share a timestamp. The chat list sorted by time and broke ties by message id. Those ids end in question ids the model makes up, so the rows came out in alphabetical id order. The list and the host's conversation outline now keep the journal's order on ties. Terminal-backed chats keep their id tie-break, because their sources have no shared order. Nothing persisted changes shape.

Review loops. Converged in two loops.

• The start readiness check found two small items:
  • Confusing comparator names: loop 1 renamed the one that breaks ties by id.
  • A stale comment: it's in a module only tests use, so it's left as a dead-code follow-up.
• Loop 2 was clean. It corrected the PR body's wording about the conversation outline, which the host publishes: the order of two user messages sent in the same millisecond can differ between old and new versions.

Readiness checks. Start and end both passed; the end check found no issues.

Tests. A new end-to-end test drives a real three-question Codex ask through:

• the real host journal on disk
• the answer and cancel paths
• the client reducer
• the projections

On main it reproduces all three wrong orders. Every new test fails with the fix removed.

Live QA against real Codex in a background dev build with an isolated profile. The Codex question tool was switched on for the run only. The question ids sorted differently from the asked order, so an id sort would have shown up. The rows read Q1, Q2, Q3:

• while pending
• after answering one at a time
• when fully answered
• when cancelled (twice)
• after two reloads and a full app restart

Normal Codex and Claude chats showed no rows moving while replies streamed. Before and after screenshots are in the PR body.

Known, not caused by this PR:

• The waiting list folds after each answer. The waiting group is keyed to its first unanswered question, which changes after each answer. Showing one row per ask would fix that as a separate change.
• Codex can't ask here by default. A default structured Codex chat can't ask questions at all today: Codex offers its question tool only in Plan mode, and /plan is refused in chat sessions.
• One-off Claude scroll. In one Claude chat during QA, the view stopped at the new message with "Jump to latest" showing instead of following the reply. It was not checked on main.

• Reworked ordering onto an explicit journal position — 458f7f8 drops the tie-preserving comparator from cf8ecbc and instead gives every journal row a journalPosition ({ sequence, index }), so ordering no longer reads the provider clock at all (src/shared/agent-session-journal-position.ts).
• Host records and preserves the place within a write — the reducer now iterates row.mutations.entries() and passes the index into journalRenderItem, which emits sequenceIndex only when non-zero; upsertItem pins the creating write's sequence, sequenceIndex and observedAt across revisions, so an answer or cancel moves content but not the bubble (journal-reducer.ts, journal-render-item.ts).
• One comparator for host and client — renderJournalState, projectJournalBatch, replacePage and mergeItems all sort by compareAgentJournalItems; projectNativeChatTranscriptMessages defaults to the new compareNativeChatTranscriptMessages, which ranks positioned rows by position and leaves outbox/streaming/terminal rows on the old time-then-id order (structured-agent-session-reducer.ts, agent-session-journal-batch.ts, native-chat-transcript-projection.ts).
• Structured projections carry the position — both the message and pending-question projections build rows through agentJournalItemRowOrigin(item), and NativeChatMessage gains the optional journalPosition field (structured-agent-session-projection.ts, structured-agent-question-projection.ts, native-chat-types.ts).
• Tests pin the new semantics — a crash-recovered row sorts by journal position despite an earlier clock, a shuffled single write sorts by place, and an outbox send sorts below every journal row (structured-agent-session-transcript-order.test.ts, journal-reducer.test.ts, structured-agent-session-reducer.test.ts, rail-outline-parity).

I read the incremental range and the full diff, traced the host reducer → wire → client reducer → transcript projection path, and confirmed mobile renders the shared reducer's order without re-sorting. The five ordering suites pass (61 tests) and pnpm tc:node passes.

• Refused sends keep their journal place — projectStructuredAgentSessionMessages now collects rejected journal items into a refused map and hands a matching outbox entry that item's journal position, so a send the host journalled before the provider refused it no longer drops below everything the agent wrote after it (src/shared/structured-agent-session-message-projection.ts:24).
• Worker reads and archives drop the list-only field — boundMessage destructures journalPosition out, so worker-read --source transcript, its remote variant, and boundStructuredJournalTail never carry a field that only orders a live list; NativeChatMessage.journalPosition's doc says so (src/main/runtime/orchestration/worker-transcript-payload.ts:111).
• Position helper extracted — agentJournalItemPosition is pulled out of agentJournalItemRowOrigin so the refused-send path reuses the exact { sequence, sequenceIndex ?? 0 } construction instead of re-spelling it (src/shared/agent-session-journal-position.ts:23).
• Tests — a refused, still-in-the-outbox send is pinned to ['ask', refused, 'reply', next], and a structured worker's rows are asserted to lose the position (with an anti-vacuous check that the projection adds it) (structured-agent-session-transcript-order.test.ts, worker-transcript-payload.test.ts).

I traced the refused path end to end: the rejected item is excluded from visibleItems, so its key is absent from journalled, the outbox entry flows through optimistic, and reconcileStructuredAgentSessionOutbox keeps a rejected entry unless its reason is DISPATCH_REJECTED_CANCELLED; the worker bound is the single chokepoint for every worker read and archive. pnpm vitest run on the three touched suites passes (21 tests) and oxlint on the four prod files is clean.

Review status (reworked): ready for review

Head: 2d676c7ce3. CI: 31 passed, 11 skipped, 0 failed.

What changed since the last status. Rows were ordered by timestamp with a fix for ties. They are now ordered by the journal's own position: the sequence of the write, then the item's place within that write. The journal already defines this order, and it is the order the agent produced the items in.

• Place within a write: the host records each item's place within its write, works it out again when replaying, and keeps it when an item is revised. Nothing new is stored on disk.
• One comparator: the host snapshot, live batches, client reducer, desktop list and host conversation outline all use it.
• Fallback: rows that are not in the journal (unsent messages, streaming rows) come after journal rows. Only among themselves are they ordered by time.
• Terminal-backed chats keep their previous order.
• Crash recovery: this also fixes rows recovered after a crash. Their timestamp can be earlier than rows written before them, so ordering by time put them in the wrong place.

Review. Treated as a fresh review because the mechanism changed.

• Start readiness check: passed, with two small findings.
  • The row position was leaking into agent-transcript reads and their saved archive. Fixed.
  • A main-process test imports renderer code. Left as is: it follows an existing precedent.
• Loop 1: also found and fixed a send that the agent refused losing its place and dropping below later rows. It now keeps the place it was recorded at.
• Loop 2: clean.
• End readiness check: passed, with no findings.
• Tests: every new test fails with its change removed. Mobile typecheck and its session tests pass.

Live QA used real Codex, in a background dev build with an isolated profile. Codex's question feature was switched on for that run only. In every ask, an id sort would have produced Q2, Q1, Q3.

• Question order: the rows read Q1, Q2, Q3 while pending, after answering one at a time, when fully answered, and when cancelled (twice). The order held after reloads.
• Follow-ups sent while Codex was working: they appeared once and never moved.
• Regression check: normal Codex and Claude chats showed no ordering problems.
• Your Codex config: ~/.codex was byte-identical after the run.

Screenshots are in the PR body.

Behaviour worth a decision, not a defect:

• Failed restart: if a send asks Orca to restart the agent and the restart fails before the host records the message, the "could not restart" line now sits just above the unsent message and its Retry. Before, it sat just below. Keeping it below would need a special link between the two rows.

Other observations:

• Early follow-ups: a follow-up sent before the agent's first words shows where the user sent it. Codex's own log records it after that reply, because Codex read it later. Showing it where it was sent matches the journal, which records it at send time.
• Claude chat scrolling: in the Claude chat, the view stopped following new replies and showed "Jump to latest", as in the first QA run. This was not checked on main.
• The waiting list: the "Awaiting user input" list still folds after each answer. Fixing that would mean showing one row per Codex ask, as a separate change.

• Failed-restart ordering pinned through the chat projection — a new end-to-end test drives a start the host could not make and asserts the error row draws below both accepted messages ([first, second, errorRow]), and a second host test asserts the same relative order when a restarted child exits before proving its start (structured-agent-session-accept-then-deliver.test.ts, structured-agent-session-send-restarts-failed-start.test.ts).
• Shared test helper — hostTestDrawnRowIds builds the composer's outbox and runs it through the real projectStructuredAgentSessionMessages → projectNativeChatTranscriptMessages path, so the assertions read what a chat actually draws (structured-agent-session-host-test-data.ts).
• Mechanical reducer fold — the batch-item write is collapsed onto locals ({ revision, body }, producer, item) to stay under the file's line limit after the origin/main merge; semantics are unchanged (journal-reducer.ts).
• Merge of current main — 040288e brought main's structured-agent-session-* changes in; the sequenceIndex logic and upsertItem's position-pinning survived intact.

I re-ran the two changed host suites, the journal and client reducer suites, pnpm tc:node, and oxlint on the four changed files — all pass. Ablating the refused-send journalPosition in structured-agent-session-message-projection.ts makes both new tests fail (the message drops below the error/cause row), so the tests are not vacuous.

This run covers 8c94a44, a merge of origin/main (5219b8a) into the branch. The merge had two conflicts, both resolved without losing either side's work:

• Journal position and main's projection changes coexist — in src/shared/structured-agent-session-projection.ts the resolution keeps the PR's agentJournalItemRowOrigin(item) import and the row-origin spread in projectStructuredItemToNativeChat, while taking main's removal of the now-unused readAgentJournalTurnOutcome import.
• Both new failed-start tests retained — in structured-agent-session-accept-then-deliver.test.ts the resolution keeps the PR's draws the messages it failed above the error row, since they were accepted first test and main's notifies failed once for the queued messages one start failure refused test, merging the import list to add AgentSessionTurnCompletionEvent.

I confirmed git diff 5219b8a..8c94a44 over the PR's own files introduces only the PR's changes — no hunk reverts a line main added, so the merge genuinely preserved both sides rather than favoring one. I then re-ran the eight touched suites (136 tests, including both conflict files and main's structured-agent-session-projection.test.ts), pnpm tc:node, and oxlint on the conflict files — all pass.

Update: now on current main (head 8c94a44649). CI is green and the PR is mergeable.

• Current main merged in, as merge commits with no rebase or force-push. That brings in fix(native-chat): a message is accepted, then delivered #22821, where a message is accepted before it is delivered, and fix(native-chat): a request that failed reads as failed #22944, where a failed request reads as failed. The fix(native-chat): a request that failed reads as failed #22944 merge only conflicted in an import block. Neither change adds rows or sorts that bypass journal-position ordering.
• Failed restart order is settled. Since fix(native-chat): a message is accepted, then delivered #22821, the host records a message before it restarts the agent. So when a restart fails, the order is the message, then the "could not restart" line, then Retry by the composer. That is the same order as reference chat apps that save the message before starting the turn. This PR's refused-send fix keeps the rejected message at its recorded place. Two host-path tests drive a real failed start; with that fix removed, both fail with the old wrong order.
• A focused review of the first merge was clean.
• CI: one shard failed on structured-agent-session-refusal-retry.test.ts, when the test's temp folder cleanup hit ENOTEMPTY. This PR doesn't touch that file, and the same flake shows up locally under load. It passed when the failed job was re-run.
