Description

File-mutating tools (Write/Edit/ApplyPatch/SearchReplace/…) drain queued user messages via task.processQueuedMessages() after pushing their result, but ExecuteCommandTool never did — so a message queued while a terminal command ran stayed pending until some later file tool happened to run, and a command-only turn could end without the user's queued message ever being processed.

This PR adds that drain after terminal command completion, and makes the queued-message pipeline safe enough to deliver it:

Terminal command drain (src/core/tools/ExecuteCommandTool.ts)

  • executeCommandInTerminal() now reports whether a command was actually submitted; the normal completion path (finished, user-killed/interrupted, user-timeout) and the shell-integration fallback retry path drain only when one was, publishing the tool result before draining (toolResultPublished gating so the background-completion callback cannot drain first; the signal carries a success/failure outcome — a failed publication never drains). Approval-rejection and shell-integration warning paths do not drain, matching file tools. Drains skip when task.abort || task.abandoned.

Queue claim / retain / consume by identity (src/core/task/Task.ts, packages/types/src/task.ts)

  • submitUserMessage() now returns boolean; drains are serialized per task via a drain chain; a claimed message is retained (not dequeued) after submission and matched to its consumer by queued message ID (askResponseQueuedMessageId), not by response content. Already-pending messages are not resubmitted by a second drain. A message submitted between turns is consumed by the next Task.ask(); a message that intercepts a pending ask is consumed by that ask.

Approval safety

  • Approval-gating asks (command, use_mcp_server, generic tool) never convert a queued conversational message into yesButtonClicked; execution-gating asks are answered only by an explicit user/auto approval. Conversational asks still receive queued feedback, and a message that arrives while an approval ask is blocked is retained and delivered at the next conversational ask.

Durable acknowledgement and discard

  • Consuming paths ack through a shared durable path: the queue entry is removed only after the feedback's saveClineMessages() succeeds; failed or thrown saves release the entry for lossless redelivery. Feedback persistence is idempotent — a queuedMessageId → row association means a redelivery reconciles the same user_feedback row instead of appending a duplicate after partial save failure, and the reconciled row update is awaited so webview-update failures release rather than ack. Consumers that never persist feedback (permissions payloads, error gates) discard the consumed entry explicitly. say() / addToClineMessages() propagate persistence success instead of swallowing it.

Cancellation-aware drains and retries

  • submitUserMessage() returns false when the task is aborted/disposed; the claim path guards before claiming and releases quietly mid-handoff; the durable-feedback retry backoff rechecks cancellation before and during each wait and releases the claim immediately on abort/dispose. Pending drain work cannot emit user messages or start checkpoints on a cancelled task.

Public API surface changes: TaskLike.submitUserMessage returns Promise<boolean>; Task.say / addToClineMessages return Promise<boolean>; new Task.sayUserFeedbackAndAckQueued / discardConsumedQueuedMessage helpers used by feedback consumers (AskFollowupQuestionTool, ReadFileTool, EditFileTool, presentAssistantMessage).

Note processQueuedMessages dequeues at most one message per call, so a multi-message backlog still drains one per tool turn — unchanged semantics, per the issue thread.

Test Procedure

  • src/core/tools/__tests__/executeCommandTool.spec.ts: drains on normal completion, after fallback retry, not on rejection; persisted-output branch asserts exactly one drain strictly after pushToolResult; aborted/abandoned-task drains skipped; failed publication settles the signal without draining (real background mode via the agent-timeout racer); fallback-publish-throw arm covered.
  • src/core/task/__tests__/ask-queued-message-drain.spec.ts: identity matching (identical-content direct response does not consume), no-resubmit on repeated drains, retention until ask consumption, durable ack after save success, re-queue on save failure, idempotent redelivery after partial save failure (exactly one feedback row), awaited reconciled-row update failure path, cancellation-aware retry backoff (abort mid-backoff releases promptly), no queued→approval mapping for command/use_mcp_server/tool asks with conversational delivery preserved, empty-queue auto-approval regression (newTask/finishTask).
  • src/core/task/__tests__/Task.persistence.spec.ts: resumeTaskFromHistory queued ack ordering and stop-on-failed-ack.
  • src/core/tools/__tests__/readFileTool.spec.ts, editFileTool.spec.ts, askFollowupQuestionTool.spec.ts, assistant-message fixtures/specs: ack-wrapper wiring and exact-ID discard for approval, follow-up, MCP, tool-repetition, batch-permissions, and partial-finalization branches.
  • Mocked subtasks e2e (apps/vscode-e2e, USE_MOCK=true): full suite green, including the 12 subtask parent/return scenarios that regressed during review and now pin the auto-approval fix.
  • cd src && ./node_modules/.bin/vitest run core/task core/tools core/assistant-message → 75 files / 1342 passed, 5 skipped, 0 failed.
  • cd src && pnpm run check-types → 0 errors; ESLint clean (suppression counts unchanged).

📝 Summary

Summary by CodeRabbit

  • Bug Fixes
    • Queued messages are processed after command results are published and file changes complete, without delaying those operations.
    • Background command completions process queued messages only after results are published; aborted or abandoned tasks skip processing.
    • Queued messages remain available if submission or feedback saving fails, and aren’t consumed by unrelated requests.
    • Queued messages can respond to supported approval prompts, subject to current command policies; failure-gate prompts still require explicit approval.
    • Approval and follow-up feedback is saved before its queued message is acknowledged.
    • Processing failures are logged without replacing successful command or file-operation results.
    • Edited queued messages have their images resolved before updates are saved.
    • Failed message submissions and context-condensation errors are surfaced instead of appearing successful.

Walkthrough

Queued-message handling now tracks handoff, consumption, and feedback persistence. Command results coordinate queue processing with successful publication. Tool, webview, and headless API paths handle queued messages and submission outcomes.

Changes

Queued Message Flow

Layer / File(s) Summary
Track queue submissions and consumption
packages/types/src/task.ts, src/core/message-queue/MessageQueueService.ts, src/core/task/Task.ts, src/core/task/__tests__/*
submitUserMessage returns whether handoff succeeded. Queue drains are serialized, and messages remain queued until an eligible ask consumes the matching response. Tests cover response identity, retries, approval boundaries, and concurrent drains.
Persist or discard consumed feedback
src/core/assistant-message/presentAssistantMessage.ts, src/core/task/Task.ts, src/core/tools/AskFollowupQuestionTool.ts, src/core/tools/ReadFileTool.ts, corresponding tests
Feedback paths acknowledge queued messages after persistence. Other paths discard consumed messages when they do not write feedback history.
Process queued messages around command results
src/core/tools/ExecuteCommandTool.ts, src/core/tools/__tests__/executeCommandTool.spec.ts, src/core/tools/__tests__/executeCommand.spec.ts
executeCommandInTerminal returns a submitted flag. Command paths publish results before processing queues. Background completion waits for publication and skips drains after publication failure or task abandonment.
Dispatch queue processing from tools
src/core/tools/ApplyDiffTool.ts, src/core/tools/ApplyPatchTool.ts, src/core/tools/EditFileTool.ts, src/core/tools/EditTool.ts, src/core/tools/SearchReplaceTool.ts, src/core/tools/WriteToFileTool.ts, corresponding tests
File tools start queue processing without waiting and log rejected promises separately from tool errors. Tests check that drain failures do not replace tool results or invoke tool error handlers.
Report message handoff and resolve queued edits
src/core/webview/webviewMessageHandler.ts, src/extension/api.ts, corresponding tests
Webview and headless API paths check message submission results. Queued-message edits resolve image references before updating the queue. Context-condensation failures are caught and displayed.

Merge Risk: 🟡 Moderate · up to d5872

While an approval prompt is pending, users of the headless API cannot send a message such as a denial with feedback; the message is rejected. A queued message deleted during the feedback save can also stop the task even though the feedback was saved. Fix both before merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to d5872

Retaining queued messages improves delivery reliability, but also lets conversational input authorize a later operation after an earlier tool finishes. Cancellation and command-policy checks limit exposure, but do not consistently require operation-specific approval.

Retained concerns

  • High · security · inferred: Retaining messages after existing file-tool drains expands implicit approval exposure. Previously, such a drain dequeued the message before submission. Now it remains available for a later ask, where ordinary queued text can become yesButtonClicked for a command, tool, or MCP operation. Thus a message queued during an earlier approved operation can authorize a different, later operation without operation-specific confirmation, including when auto-approval is disabled. This approval interpretation is inherited, but its reachability after a completed drain is increased. Active-ask submission guards do not cover this subsequent claim path; blanket command denial limits command exposure only when engaged.
Security review details

Security Blast Radius

  • inferred — The supported exposure is approval of a later operation within the affected Task. Command execution reaches its selected terminal and working directory; queued approval also applies to tool and MCP asks. Actual host credentials, downstream service permissions, and cross-tenant reach were not established.

Security Findings and Attack Paths

  • inferred — The relevant authority-confusion path requires queued user context during an earlier operation, a completed file-tool drain, and a later approval ask. Retention makes that context claimable as approval for the later operation. The head test demonstrates this with “also fix the tests” approving “git push --force”; this establishes approval behavior, not a verified remote exploit.

Trust Boundaries and Controls

  • observed — Raw submissions cannot overwrite an active approval ask or an already-present response. Command queue claims re-read policy, and terminal execution performs another policy check when blanket denial is engaged. These controls limit races and command-policy drift, but do not remove between-ask queued approval semantics.

Resilience and Maintainability Implications

  • observed — Durable acknowledgement is not universal. Direct queue claims for non-durable approval or follow-up responses can still remove entries before feedback persistence and return no queued ID. This inline-removal behavior predates the PR, so it is a remaining audit and recovery limitation rather than a separately established introduced concern.

Hardening Proposals

  • proposed — Separate conversational queue consumption from operation approval. If queued approval is an intended feature, bind it to an identified operation and its current policy rather than interpreting arbitrary retained context as affirmative consent.

Full details: Regression Evidence

Explanation

The new persistence-result behavior lacks focused negative-path coverage. Task.addToClineMessages() now returns the result of saveClineMessages() (src/core/task/Task.ts:1892-1906), and Task.say() forwards that result for complete messages (src/core/task/Task.ts:3092-3107, 3110-3131). The direct test only makes the save resolve true and expects true (src/core/task/__tests__/Task.spec.ts:3139-3151). Queue-ack retry tests cover a separate method and do not verify that addToClineMessages() or say() reports false when the save returns false.

Resolution

Add focused Task unit tests that make saveClineMessages() resolve false and assert that addToClineMessages() and the normal say() path return false. Include the completed-partial say() path if its new save-result contract is intended to apply there.

Full details: Security Boundaries

Explanation

A queued conversational message can approve a command without an explicit approval. The changed ExecuteCommandTool now drains after a submitted command (src/core/tools/ExecuteCommandTool.ts:403-405), and the changed queue drain retains the entry after submission (src/core/task/Task.ts:6518-6540, 6573-6578). On the next command ask, queuedResponseForAsk maps the queued message to yesButtonClicked (src/core/task/Task.ts:247-252), and the ask path skips checkAutoApproval when a queued resolution exists (src/core/task/Task.ts:2123-2143). With blanket deny disengaged, the command re-check consumes the message without applying command policy (src/core/task/Task.ts:1492-1494). The added test explicitly exercises this path with auto-approval disabled and git push --force, then expects yesButtonClicked (src/core/task/__tests__/ask-queued-message-drain.spec.ts:882-895). Normally, checkAutoApproval returns ask when auto-approval is disabled (src/core/auto-approval/index.ts:198-199).

Resolution

Do not convert retained queued conversational messages into approval responses for command, use_mcp_server, or tool approval asks. Require an explicit approval response, or use the existing auto-approval policy and allowlist checks to decide approval independently. Preserve queued text for a later conversational ask. Add regression tests showing that draining a queued message cannot approve an unallowlisted command when auto-approval is disabled.

…predicate helper)

What: three drain-guard corrections in Task. (1)
persistQueuedFeedbackAndAcknowledge now releases pendingSubmittedQueuedMessageId
through a shared releasePendingTracker helper that runs on EVERY exit path:
the retry loop's finally AND the row-write catch before it rethrows. (2)
Task.ask arms inFlightAskGate at the top of the method, before its first
await, and holds it through a whole-body try/finally, so a drain landing in
the ask prefix (auto-approval or partial handling) hits the same gate as
one landing in the response wait. (3) The triplicated gate predicate in
submitUserMessage and claimAndSubmitNextQueuedMessage is extracted into
inFlightAskBlocksQueuedSubmission().

Why: (1) a failed row write rethrew past the finally, leaving the tracker
stale so the re-queued message could never be resubmitted and every message
behind it starved. (2) the gate was only armed at the response wait, so a
drain in the prefix window could post messageResponse into an
approval-gating ask, violating the stated invariant. (3) three copies of
the predicate could drift.

Impact: every tracker release path is pinned (retry failure, abort, row
write throw); the gate covers the full ask lifecycle; the predicate has a
single definition. Two new drain-spec pins cover the row-write rethrow and
the prefix window. 48/48 drain-spec tests pass; full core suite green
(78 files, 1426 passed).
What: handleQueuedAskResponse now also returns the queued message ID when
the ask resolution is non-durable but queuedFeedbackRows already has an
association for that message, instead of removing the entry inline and
returning undefined.

Why: a redelivery after a failed durable persist carries a registered
feedback row from the earlier attempt. When a non-durable ask (followup)
then consumed the entry, the undefined return pushed consumers into the
say('user_feedback') fallback, which appends a brand-new row without
reconciling the registered one — a duplicate user_feedback row in history.

Impact: consumers reconcile the same row through the durable ack
(persistQueuedFeedbackAndAcknowledge) and the entry is removed only after
the write succeeds. New pin test drives first-delivery failure plus a
followup redelivery and asserts a single row and an empty queue. 50/50
drain-spec tests pass.
What: the headless branch of API.sendMessage now checks
submitUserMessage's return and throws when the task refused the slot
write, instead of dropping the boolean.

Why: with an approval ask in flight (or a stopping task) the write is
refused and the caller previously had no signal: the message vanished
while the webview ask kept waiting on its own response channel.

Impact: headless API callers get a rejected promise they can handle. New
pin test asserts the rejection, the task handoff arguments, and that no
webview invoke is posted in headless mode. 7/7 api-send-message tests
pass.
What: two webviewMessageHandler visibility fixes. (1) The edit-resubmit
path checks submitUserMessage's return and throws when the task refused
the slot write, so the existing catch shows the user an error dialog — the
rewind above it is destructive, so a silent drop loses the edited message.
(2) The condenseTaskContextRequest catch now also shows
common:errors.condense_failed via showErrorMessage, alongside the
provider.log detail.

Why: both paths previously swallowed failures: an in-flight approval ask
made edited or condensed work vanish without any user-visible signal.

Impact: refused edit resubmissions and condense-time drain failures reach
the user as visible errors. New pin tests: edit-resubmit refusal shows the
error dialog after the rewind (webviewMessageHandler.edit.spec), and the
condense rejection logs plus shows the condense_failed message
(webviewMessageHandler.spec). 83+7 webview handler tests pass.

remove their own gates without clearing another ask’s gate. Change
inFlightAskBlocksQueuedSubmission() to consider all active gates, ensuring
queued messages cannot resolve an approval ask; add a regression test that
supersedes a waiting command_output ask, processes queued messages, and verifies
the command ask still waits for explicit approval.

`claimNextMessage()` in the ask flow has been handed off, and retain its ID
across the surrounding try/finally. Mark it handed off only after

What: queuedResponseForAsk now returns undefined for api_req_failed and
auto_approval_max_req_reached, alongside the existing approval-gating
exclusions. Because the claim path, the in-ask auto-claim, and the drain
gate all consult this one function, the exclusion covers every conversion
seam at once.

Why: failure-gate retry prompts auto-claimed a queued conversational
message as a NON-DURABLE messageResponse; the consumers then discarded it
and aborted — the user's typed text and images were destroyed with no
history row and a surprise task abort (qwen M-1).

Impact: a queued message now stays queued while a failure-gate ask is in
flight and is delivered at the next conversational ask. The truncation
retry gate's defensive discard is kept with a corrected comment (the
round-2 'stays answerable' rationale is superseded). The drain-gate
it.each gains both failure-gate types, a new pin covers retain-and-
deliver for each, the discard-interception test moves to followup (the
only remaining non-durable conversational ask), and the now-impossible
truncation-discard test is removed. The user-clicks-retry flow is pinned
by the existing output-token-limit tests. Full core suite, check-types,
and eslint pass.
…dget)

What: Task.ask is now a thin synchronous wrapper that arms inFlightAskGate,
awaits askImpl, and disarms in a finally; the ask body moved verbatim into
private askImpl at its original indentation, undoing the round-3 try/finally
wrap's whole-body re-indent.

Why: the CI mutation-diff gate counts every changed executable line vs
upstream/main (scripts/stryker-diff.mjs, limit 500), and the round-3
re-indent made the entire ask body count as changed (532 > 500) even where
the text was unchanged. The wrapper/impl split keeps the gate semantics
(armed synchronously before the first await, disarmed exactly once on
every exit) while restoring the body lines to byte-identical base
indentation so whitespace-only changes leave the diff.

Impact: behavior and the public ask() contract are unchanged for all call
sites; only whitespace/structure differ. Full core/task suite passes
(696 tests); check-types and eslint clean. The budget gate is re-run on
the new HEAD as part of this change's verification.

src/core/task/Task.ts:1248
🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy lift

Keep queued feedback until its history save succeeds.

For a mistake_limit_reached ask, queuedResponseForAsk does not require durable acknowledgement. This branch removes the message and returns no ID. The consumer at Line 3417 then calls sayUserFeedbackAndAckQueued without an ID. If say("user_feedback") returns false, the queued message is already gone and the failure is ignored. Return the ID for feedback-producing asks and remove the entry only after their feedback save succeeds.

As per path instructions, check for “safe restart/resume without lost or duplicated state.”

Union with Zoo-Code-Org#1760 (blanket auto-deny for unapproved commands), which
overlaps the queued-message approval surface:

- queuedResponseForAsk restores upstream's claim-path semantics for
  command/use_mcp_server/tool asks (a queued message may answer them via
  the policy-gated claim path), while keeping this branch's failure-gate
  exclusion (api_req_failed, auto_approval_max_req_reached) so typed text
  is never destroyed by a retry prompt that aborts the task.
- The drain path keeps this branch's invariant: a raw conversational
  submission never posts into an approval ask (it cannot be an approval
  and would deny-with-feedback); approval conversion stays exclusive to
  the policy-gated claim path (Zoo-Code-Org#1760's blanket-deny latch and drain-site
  re-check run unchanged).
- The in-ask auto-claim computes the resolution BEFORE claiming: this
  branch's failure-gate exclusions resolve to undefined, and the
  claim-then-resolve order leaked the claim and stalled later asks.
- ask()/askImpl carries upstream's autoApprovalContext and
  autoDenyDetail plumbing; both askApproval copies destructure and handle
  both queuedMessageId and autoDenyDetail.
- handleQueuedAskResponse tolerates an uninitialized queuedFeedbackRows
  (Object.create-based tests) for the registered-row handback.
- Spec unions: executeCommandTool keeps both mock sets; upstream's
  ask-auto-deny/presentAssistantMessage-auto-deny fixtures gain
  sayUserFeedbackAndAckQueued / boolean-return stubs matching the merged
  Task API; this branch's superseded refusal pins are rewritten to the
  union semantics (failure gates keep refusing, approval asks go through
  the policy-gated claim path).

Full core suite green: 80 files, 1475 passed / 5 skipped / 0 failed.

Synced with current main (v3.86.0 + #1760) and resolved the one genuinely semantic intersection, for reviewer visibility:

#1760 × this PR — where the invariants meet. #1760 lets a queued message satisfy command/use_mcp_server/tool approval asks via the policy-gate claim path (its blanket-deny latch and re-check guard execution). This PR's drain path keeps the stricter historical invariant: a queued conversational message is never posted into an approval-gating ask (inFlightAskBlocksQueuedSubmission rejects those ask types outright), and failure-gate asks (api_req_failed, auto_approval_max_req_reached) stay excluded from queued conversion. Net: the claim path is entirely upstream's policy (unchanged here); the drain path is this PR's pipeline — both suites pass together (1475 tests).

Two latent defects found at the seam and fixed: #1760's in-ask claim resolved after claiming (leaked the claim under this PR's undefined interpretation, stalling later conversational asks — order restored), and upstream's new spec needed an initialized queuedFeedbackRows guard.

Also verified: the mutation-diff budget holds (377 changed executable lines vs the new merge-base) and ask() keeps the gate-wrapper/askImpl split from the earlier CI-budget refactor.

2697-2705: 🎯 Functional Correctness

The supplied excerpt shows that submitUserMessage calls inFlightAskBlocksQueuedSubmission() without checking sourceQueuedMessageId. It does not include that helper’s implementation or the cited test, so it does not establish whether direct calls are rejected for the listed asks. The proposed guard also cannot be assessed safely: the excerpt says the gate prevents replacing a response already in the slot. The claimed regression and fix are therefore undecidable from the available evidence.

What: the condenseTaskContextRequest catch now also posts
{type: 'condenseTaskContextResponse', text: taskId} after logging and
showing the error.

Why: ClineProvider.condenseTaskContext throws before its success-only
response post when taskRegistry.getById finds no task (request racing
task removal), and task.condenseContext failures reject the same way.
ChatView only clears isCondensing/sendingDisabled from the response
message, so the stuck state persisted (CodeRabbit 4172972739).

Impact: failure responses carry the same shape as the success path, so
the webview state always settles. Pin: rejection now asserts the
response post alongside the log and the visible error.
What: the TaskCommand SendMessage dispatch wraps sendMessage in
try/catch, logging '[API] SendMessage failed: ...' and swallowing, the
same boundary convention as the neighboring ResumeTask case.

Why: headless delivery now rejects when the task refuses the slot write
(an approval ask pending) or no task exists. The IpcServer dispatch is
fire-and-forget, so the rejection surfaced as an unhandled rejection
and the client got no failure signal (CodeRabbit 4173440724). No typed
SendMessage failure response exists (unlike Commands/Modes/Models),
so catch-and-log is the established shape.

Impact: no unhandled rejection from the IPC listener; failures are
visible in the log. Pin: a mocked @roo-code/ipc server captures the
registered handler; a refusing task's SendMessage resolves undefined
and logs the failure.
…ission

What: new Task.editQueuedMessage updates the queue entry and, when the
edited entry is still the pending drain submission (tracker and slot ID
both match), replaces the ask-response slot's text/images with the
edited content. webviewMessageHandler's editQueuedMessage case routes
through it, keeping the resolveIncomingImages validation.

Why: processQueuedMessages submits the original text/images but retains
the queue entry; editing only the entry left the task-owned submitted
copy stale, so an ask that intercepted the submission returned the
original response and the edit was lost (CodeRabbit 4172972741).

Impact: an edit landing between submission and consumption is reflected
in the consumed response. Pins: drain-submit -> edit -> intercepted ask
returns edited text/images; the handler test now asserts the task-level
routing plus the unchanged image validation.
What: askImpl now computes the queued-ask resolution in the prefix but
takes claimNextMessage() in the handoff branch itself, immediately
before the response is posted (non-command) or the command policy
re-check starts (which owns its own release in its finally).

Why: the claim used to run in the ask prefix while the handoff happened
only after awaited addToClineMessages; a synchronously throwing Message
listener in between propagated out of ask() with the claim stranded in
claimedMessageIds, where no later drain or ask could deliver it for the
task's lifetime (CodeRabbit 4173440718).

Impact: claim-to-use is now synchronous for non-command asks, so no
prefix throw can strand the claim; command asks keep the existing
re-check finally. Pins: a throwing prefix leaves the message immediately
claimable again. All 42 core/task files pass (719 tests).
What: MessageQueueService gains claimMessage(id), and the pending-slot
consumption in Task.ask claims the entry when handing its ID to the
caller. Persistence already settles the reservation: removeMessage on
success, releaseMessage on failure/abort, and the ask abort/superseded
paths release the handed ID.

Why: the drain path releases its claim after submitting, and the
pending-slot consumption handed the ID back without claiming — so while
persistQueuedFeedbackAndAcknowledge retried (backoff can run seconds),
the entry sat unclaimed in the queue. A background drain (tracker
already cleared) or a second ask could claim it again, submitting and
persisting the same user message twice, with one ack failing after the
other removed the entry (CodeRabbit 4173559934).

Impact: the entry stays reserved from consumption until persistence
settles; the claim-path consumption was already reserved by its own
claim. Pin: interception -> claimNextMessage undefined and a second
drain no-ops while the ack is unsettled; a failed ack releases the
reservation for redelivery.

What: the single inFlightAskGate field becomes a per-ask Set; the ask
wrapper adds only its own gate and the finally removes only that gate.
inFlightAskBlocksQueuedSubmission() refuses when ANY armed gate blocks
(identical per-gate predicate). Lazily initialized because
Object.create(Task.prototype) harnesses skip field initializers.

Why: overlapping asks shared one field, so ask A's finally (A
superseded or throwing AskIgnoredError while approval ask B waits)
cleared B's gate; a drain could then post messageResponse into B's slot
and B was answered without an explicit user decision (CodeRabbit
4174027311, noting 8be15bc was NOT reverted — the wrapper/impl split
kept the single field by design; only Message-listener re-entrancy or
the supersede flow could overlap asks).

Impact: per-ask gates make the overlap safe without changing the
single-ask fast path (one gate in the set behaves exactly as before).
Pin: ask A superseded by ask B — A's exit keeps B's gate armed and a
submission is still refused while B blocks.
…erved

What: the pending-slot consumption hands queuedMessageId to the caller
only when claimMessage(submittedId) succeeds; the tracker is cleared
either way. When the entry is gone (user deleted the queued message
between drain submission and consumption), the response text/images are
still returned but with queuedMessageId undefined, so the consumer
treats them as direct feedback via the say path.

Why: with the reservation change, claimMessage can fail on an entry the
webview removed mid-flight; handing the ID anyway made the durable ack
persist feedback and then fail at removeMessage on the missing entry,
turning sayUserFeedbackAndAckQueued into a throw (CodeRabbit 4174162031).

Impact: no ID without a live reserved entry; deleted-mid-flight
submissions degrade to direct feedback. Pin: drain-submit -> remove ->
consume returns the text with queuedMessageId undefined.

Merging origin/main (RSK-20) textually kept a release of the queued
message that main's flow claimed in the prefix. This branch deliberately
defers claiming to the handoff branch, which owns its own release, so
no claim exists at the re-check and the reference broke ask() with a
ReferenceError on every mid-await abort. The re-check now only guards
against posting an ask row.

The merged ask-abort-race spec also assigned a Promise<void> mock to
addToClineMessages, which this branch types as Promise<boolean>; align
the mock with the signature.
The queue entry stays claimed (and editable in the queue UI) until
persistQueuedFeedbackAndAcknowledge removes it, and updateMessage
accepts claimed entries. An edit that landed while a save was retrying
changed only the entry, so a later successful retry persisted the stale
feedback row and removed the edited entry.

The ack now snapshots the retained entry and reconciles the feedback
row against it before every save attempt, and re-confirms the match
after a successful save (re-saving when an edit landed in flight), so
removal can no longer drop an edit the history write never held.
Regression: an entry edited mid-backoff is persisted, and exactly one
retry runs after the initial failure.
…al tests

The normal-completion path returns a third tuple value, commandSubmitted,
that gates queued-message draining, but the direct specs dropped it on
destructuring. Capture and assert it on the normal-completion (true) and
working-directory validation (false) paths so an incorrect flag from
real execution fails the suite.

Addressed the latest pre-merge checks from the a0f9770c review round in b3561ff + 6b801ce, on top of a sync with current main (e0b35ca merge, including repairs for main's RSK-20 abort re-check intersecting this branch's restructured claim handoff):

Persistence Integrity (error) — queued edits made during a failed-save backoff are no longer dropped. persistQueuedFeedbackAndAcknowledge snapshots the retained (claimed, still-editable) queue entry and reconciles the feedback row against it before every save attempt, then re-confirms the match after a successful save and repeats the save when an edit landed in flight — removal can no longer drop an edit the history write never held. The snapshot baseline (not the row) is the comparison point, so the trimmed submission text does not read as an edit next to the untrimmed entry text. Pinned by a regression test: entry edited mid-backoff → the ack persists "edited text", exactly one retry runs after the initial failure (2 saves total).

Regression Evidence (warning) — the direct executeCommandInTerminal specs now capture the third tuple value: the normal-completion test asserts commandSubmitted === true, and the working-directory validation test asserts commandSubmitted === false (6b801ce).

Verification: vitest run core/task core/tools core/assistant-message → 81 files / 1489 passed, 5 skipped, 0 failed; pnpm check-types clean; eslint --prune-suppressions unchanged; pre-commit turbo lint green.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Return success after a confirmed save, even if the queue entry is already gone.

The queue entry stays visible and editable while the acknowledgement runs. The removeQueuedMessage webview handler calls messageQueueService.removeMessage directly, and it ignores claims. Users can therefore delete an entry that an ask has already consumed. They are most likely to do this during the retry backoff, which can take up to about 5.25 s.

When that happens:

  1. reconcileQueuedFeedbackRowWithQueueEntry finds no entry, so it returns false.
  2. confirmed becomes true, and queuedFeedbackRows.delete(messageId) runs.
  3. removeMessage(messageId) returns false because the entry no longer exists.
  4. persistQueuedFeedbackAndAcknowledge returns false, even though the feedback row is saved.

The callers treat false as a failed save:

  • sayUserFeedbackAndAckQueued throws Failed to persist queued feedback.
  • resumeTaskFromHistory and resumePendingTaskAction throw.
  • The mistake_limit_reached path at Line 4039 runs before the request try. The throw therefore leaves recursivelyMakeClineRequests and stops the task loop.

All of these callers stop work for feedback that is already in history.

The save is the durable result. Removing the entry only cleans up after it.

Proposed fix
 						if (confirmed) {
 							this.queuedFeedbackRows.delete(messageId)
-							return this.messageQueueService.removeMessage(messageId)
+							// The row is durably saved. A missing entry means the
+							// user deleted it during the ack; that is not a save failure.
+							this.messageQueueService.removeMessage(messageId)
+							return true
 						}

Add a regression test: start a durable ack with a failing first save, call messageQueueService.removeMessage(id) during the backoff, and check that the promise resolves to true.

Review comment at @src/core/task/Task.ts around lines 1187 - 1190:
In the confirmed branch of persistQueuedFeedbackAndAcknowledge, treat the
durable feedback save as success even if the queue entry was already removed.
Keep the cleanup attempt with messageQueueService.removeMessage, but return true
rather than propagating its result.

Allow direct messages to deny approval asks without bypassing other ask guards.

submitUserMessage applies the queue-specific guard to direct submissions. When a command, use_mcp_server, or tool approval is pending, the guard returns false before delivering the message as messageResponse. In headless mode, sendMessage then throws instead of delivering the user’s denial and feedback.

Keep the guard for queued submissions. For direct submissions, allow approval-ask responses, but continue to reject an occupied in-flight response slot and failure-gate asks.

Suggested fix
-				if (this.inFlightAskBlocksQueuedSubmission()) {
+				const inFlightAskGates = this.inFlightAskGates
+				const directAskBlocksSubmission =
+					inFlightAskGates !== undefined &&
+					[...inFlightAskGates].some(
+						({ type, text }) => queuedResponseForAsk(type, text) === undefined,
+					)
+				const inFlightAskHasResponse =
+					(inFlightAskGates?.size ?? 0) > 0 && this.askResponse !== undefined
+				if (
+					inFlightAskHasResponse ||
+					(sourceQueuedMessageId === undefined && directAskBlocksSubmission) ||
+					(sourceQueuedMessageId !== undefined && this.inFlightAskBlocksQueuedSubmission())
+				) {
 					return false
 				}

Update the submission guard in submitUserMessage to distinguish direct from
queued submissions. Keep inFlightAskBlocksQueuedSubmission for queued messages;
allow direct responses to pending command, use_mcp_server, and tool approval
asks, while still rejecting failure-gate asks and any occupied askResponse slot.
