Explanation
The prior lifecycle failure remains. In changed Qwen paths,
createMessageandcompletePromptcallsettleOnAbort(this.ensureAuthenticated(), ...), butsettleOnAbortonly rejects the caller's wait.loadCachedQwenCredentialsstill awaits uncancellablefs.readFile(qwen-code.ts:93-103), anddoRefreshAccessTokenstill callsfetchwithout a signal (qwen-code.ts:124-142).credentialLoadandrefreshPromiseremain retained until those operations settle (qwen-code.ts:106-121, 188-205). A stop during a hung credential read or token refresh therefore leaves provider I/O running after the request has ended. The changed refresh path can also write credentials and updatethis.credentialsafter cancellation (qwen-code.ts:163-177). The added tests explicitly keep these operations pending after abort (qwen-code.spec.ts:406-428 and 749-795).Resolution
Give shared credential loads and token refreshes explicit ownership. Track active waiters and abort the underlying
fs.readFileand token-refreshfetchwhen the last waiter cancels, or enforce a bounded lifetime with cleanup. ClearcredentialLoadandrefreshPromisewhen an underlying operation is aborted, and prevent post-cancellation credential writes and retries.

…ess review
CI: platform-unit-test (ubuntu-latest) was failing on four LM Studio spec
assertions that still expected the pre-PR single-argument SDK call shape.
createMessage now calls chat.completions.create(params, { signal }) with the
request-local AbortSignal, and completePrompt passes no options when no
signal/timeout is configured. Update the two existing specs to the same
two-argument assertions used by the new qwen-code-native-tools.spec.ts
(expect.any(AbortSignal) for createMessage, undefined second argument for the
no-signal completePrompt case).
Review: (1) narrow isRequestAborted to an exact match on the OpenAI SDK abort
error text ("Request was aborted.") instead of a substring scan, so unrelated
errors that merely mention "abort" are no longer normalized as user
cancellations; (2) abort the request-local controller in the createMessage
finally block so early stream termination (break/return) cancels the
in-flight SDK request.

161-269: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick winCover abort during input token counting before merge.
The added cases cover pre-abort and in-flight cancellation, but they do not cover an abort while
countTokens()is pending. Insrc/api/providers/lm-studio.ts, the abort listener is registered only afterawait this.countTokens(...). If the caller aborts during that await, the request-local controller is not aborted, andchat.completions.createcan still start. Add a deferredcountTokens()regression test that aborts during the await and asserts that the completion call does not start. Move the signal bridge before the first await or add a post-count abort check so the test passes.As per coding guidelines, regressions should be tested at the lowest layer that would have failed.

…overage Codecov's patch report on the previous head flagged 5 partial-coverage lines in qwen-code.ts (lines 328, 338, 344, 398, 399): the defensive branches of the createMessage stream loop — a chunk with no choice (choices[0] ?? fallback), a delta that repeats the previous full content (empty after trimming), a think block that starts the text (empty leading split segment), and a zeroed usage payload (prompt_tokens || 0, completion_tokens || 0). Add one focused degenerate-stream-shapes test to qwen-code-native-tools spec covering all five branches in a single stream. Branch-level lcov cross-reference on the PR's added lines now reports zero partial-coverage added lines in both provider files, and line-level changed-line coverage stays 100% (lm-studio.ts 35/35, qwen-code.ts 65/65 executable added lines).
…o abort-signal utils The OpenAI-family provider PRs (Zoo-Code-Org#1309, Zoo-Code-Org#1311) carry per-provider copies of the same abort-detection helper (isRequestAborted) and the same abort-error constructor (createAbortError); only the provider name in the message differs. Per the CodeRabbit maintainability finding on Zoo-Code-Org#1309 (extract the shared abort helpers into utils/abort-signal.ts), these are now shared in the foundation utility: - isRequestAborted(error, signal?) - true when the caller signal fired, a native AbortError / OpenAI SDK APIUserAbortError was raised, or the message is exactly "Request was aborted." (exact match; a substring match would misclassify unrelated errors that merely mention aborting) - createAbortError(providerName) - fresh error with name === "AbortError" and message "The <providerName> request was aborted", satisfying the Task.ts abort contract - exported OpenAiRequestOptions type 7 new tests (isRequestAborted 4, createAbortError 3).

…oken counting CodeRabbit follow-ups on the abort-signal series: an abort landing while the qwen-code 401 retry request is in flight escaped callApiWithRetry as the raw SDK abort error instead of the normalized 'The Qwen Code request was aborted'; the retried apiCall now goes through the same isRequestAborted normalization. In lm-studio createMessage, an abort landing while input token counting is pending was silently dropped (a listener added to an already-aborted signal never fires), so the aborted state is bridged into the request-local controller and throwIfAborted fast-fails before the request is issued. Regression tests cover both paths.

- Around line 771-793: Update both 401 refresh abort tests for `createMessage`
to abort while the refresh is pending: have `fetchMock` return a promise that
never settles, call `stream.next()` before draining microtasks until `fetchMock`
is called, then abort the external signal. Preserve the assertions for
`AbortError` and exactly one `mockCreate` call.

capture the listener passed to `addEventListener` and assert that
`removeEventListener` receives that same function reference. Apply this to both
the request-local signal test and the stream-completion removal test; replace
`expect.any(Function)` checks without changing the production behavior.

441-455: 🎯 Functional CorrectnessThe finding depends on a repository consumer that changes behavior when
completePromptreports a timeout asAbortErrorinstead of aTimeoutError. The inspected evidence finds no such consumer, so no material consequence survives.
- The search for
completePrompt(calls that passtimeoutMsreturned no matches outside tests. The check therefore finds no caller that sets a per-call timeout on this path.- The search for
TimeoutErrorbranches returned onlysrc/core/checkpoints/index.ts:122, which checkserr.name === "TimeoutError"for checkpoint initialization. That branch is unrelated to Qwen Code.- The search for
name === "AbortError"branches undersrc/corereturned no match. The only abort-related branch wassrc/core/task/Task.ts:556, which suppresses errors whose message ends in "aborted". Nothing in this path distinguishes a timeout from a user stop.The claimed mechanism is only partly supported. The file change summary states that
callApiWithRetryconverts aborted requests toAbortError, which is consistent with the comment's description. However, I did not inspect thesettleOnAbortorisRequestAbortedimplementations, so the claim that a timeout reason is lost is not verified from source. The comment's remedy also depends on that unverified behavior and on a caller that does not appear to exist.Because no repository caller depends on the distinction, the comment's stated impact ("a per-call timeout silently looks like a cancellation" with a fallback skipped) is hypothetical. The comment also states that a pre-PR timeout surfaced as an SDK timeout error, but that baseline was not inspected.

… Qwen credential loads settleOnAbort's already-aborted early return handed the caller the abort error without attaching a rejection handler to the pending promise, exposing a rejecting pending promise as an unhandled rejection. A no-op rejection guard now runs before the early return (same shape as rejectOnAbort's existing guard). New test aborts with a rejecting pending promise and asserts no unhandledRejection fires while the abort error surfaces (negative control: removing the guard fails exactly that test). QwenCodeHandler duplicated credential loading after cancellation: createMessage/completePrompt race ensureAuthenticated() with settleOnAbort, so a cancelled first request left its load running and a second request started a fresh credential read. ensureAuthenticated now shares the in-flight load promise the same way refreshAccessToken shares its refresh, cleared in a finally once the load settles, so a failed load is retried by the next request. New tests: concurrent cancel+retry reuses one credential read; success and failure both clear the shared promise (negative control: breaking the reuse guard fails exactly the reuse test; the test releases the hung read in a finally so a failing run cannot leak the pending load into later tests). Review test-fidelity threads: the two qwen-code-native-tools 401 refresh tests now abort only after the refresh wait is established (fetch never settles; drain until the fetch starts) instead of aborting synchronously inside the fetch mock, which exercised only the already-aborted fast path; the two qwen-code listener tests now assert the exact registered listener reference is removed instead of expect.any(Function). Verification at this head: 128/128 green across abort-signal, qwen-code, qwen-code-native-tools and lm-studio specs; tsc --noEmit 0 errors; eslint --max-warnings=0 clean with suppression counts unchanged; prettier clean.

createMessage's finally block cancels the request-local SDK signal and detaches the external abort listener, but no test pinned the early consumer exit (break/return while the SDK stream is still pending): the existing coverage only exercised normal completion and external-signal aborts. New test consumes one chunk from a stream that then stays pending, calls stream.return(), and asserts the request-local SDK signal becomes aborted and the exact registered external listener is removed (by reference, per the established pattern). Negative control: removing the finally-block abort fails exactly this test (isolated run). Verification at this head: 27/27 green in lm-studio.spec.ts; tsc --noEmit 0 errors; eslint --max-warnings=0 clean with suppression counts unchanged; prettier clean.

The early-termination test only observed the request-local signal after stream.return(), so a premature abort (one landing while the consumer is still iterating) would also pass. The test now captures the SDK request options after the first chunk and asserts the request-local signal is still live (aborted === false) before the early return, retaining the post-return aborted assertion. Negative control: aborting the request-local controller right after the SDK create call fails exactly this test (isolated run: the new false assertion reddens).

Conflict resolution: keep the branch's abort wiring (lm-studio isRequestAborted catch classification in createMessage/ completePrompt, completePrompt fast-fail + merged request signal; qwen-code completePrompt fast-fail, merged signal and settleOnAbort-wrapped auth wait). Post-merge lint repair for the re-enabled unused-variable rule: drop the unused countSpy binding in lm-studio.spec.ts and rename two unread mock args to _opts in qwen-code-native-tools.spec.ts. Pre-existing well-formed Stryker directives in lm-studio.ts and qwen-code.ts are retained: the merged scripts/stryker-diff.mjs validates directive format as an advisory only, and their mutants are equivalent; removing them without maintainer gate-config exclusions would turn equivalent mutants into blocking Survived. Verification at this merge: 129/129 green across lm-studio, qwen-code, qwen-code-native-tools and abort-signal specs; tsc --noEmit 0 errors; eslint --max-warnings=0 clean (suppression entries for lm-studio-timeout.spec.ts and qwen-code.ts pruned as stale - both files lint clean without them); prettier clean.

…meout delays Port of the Zoo-Code-Org#1300 timeout guard finding (CodeRabbit): Node's AbortSignal.timeout throws ERR_OUT_OF_RANGE for non-integer delays (Infinity) and clamps delays above 2^31-1 ms to 1 ms, so a non-finite timeoutMs threw a RangeError instead of running the request, and an overflowing one aborted almost immediately. The helper now treats non-finite values as "no timeout" and caps finite delays at 2^31-1 ms. Regression tests added; negative controls (reverting the guard) fail exactly the two new tests.

CodeRabbit follow-up on the timeout guard: Node validates AbortSignal.timeout delays as uint32, so finite fractions (1500.5, 0.5) threw ERR_OUT_OF_RANGE just like Infinity did. The helper now rounds delays up (a positive fraction never becomes 0 ms) before capping at 2^31-1 ms. Regression test mergeAbortSignalAndTimeout (undefined, 1.5); negative control (reverting the rounding) fails exactly that test.
CodeRabbit: the fractional-timeout test only proved the call did not throw and eventually aborted - a round-down mutation (1.5 -> 1) would still pass. The test now spies AbortSignal.timeout and pins the received delay: 2 for 1.5 and 1 for 0.5 (never 0). Negative control: mutating Math.ceil to Math.floor fails exactly this test.

Description
Round 2 of the abort-signal series: wires the caller's abort signal through the request paths of two more providers, LM Studio and Qwen Code, so that a Stop pressed in the UI actually cancels the in-flight provider request and surfaces a normalized abort error (per the Task.ts contract: name = "AbortError", message ending in "aborted" — no trailing period).
RequestConfigBuilder is adopted from the start (generic RequestConfigBuilder only — no SDK-extended variant classes). The builder and utils/abort-signal.ts are untouched (foundation contract frozen).

Port of the #1300 CodeRabbit finding to the shared mergeAbortSignalAndTimeout helper: non-finite timeoutMs (Infinity) now means "no timeout" instead of throwing ERR_OUT_OF_RANGE from AbortSignal.timeout, and finite delays are capped at 2^31-1 ms (Node clamps larger delays to 1ms, which aborted requests almost immediately). Regression tests added; negative controls fail exactly the two new tests. Identical helper fix lands in every unit of the abort series (merge-order aware); canonical copy in #1293.
Fractional-timeout rounding wave
Follow-up CR round: Node validates AbortSignal.timeout delays as uint32, so finite fractions (1500.5, 0.5) threw ERR_OUT_OF_RANGE like Infinity did. mergeAbortSignalAndTimeout now rounds delays up (a positive fraction never becomes 0 ms) before capping at 2^31-1 ms; regression test mergeAbortSignalAndTimeout(undefined, 1.5). Identical helper patch in every unit of the series (merge-order aware, canonical in #1293).
Assertion strengthening (rounding wave follow-up)
The fractional-timeout test now spies AbortSignal.timeout and pins the received delay (2 for 1.5, 1 for 0.5, never 0) instead of only asserting no-throw plus eventual abort; a round-down mutation (Math.ceil -> Math.floor) fails exactly this test. Identical patch in every unit of the series (canonical in #1293).
