WalkthroughProvider handlers now forward abort signals and positive timeouts, normalize SDK cancellation failures to ChangesProvider cancellation normalization
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to Some Opencode Go requests will not honor cancellation or timeouts consistently, while pre-aborted requests across several providers can still perform fallible setup and return the wrong error. These cancellation-contract regressions should be fixed before merge. Sequence Diagram(s)sequenceDiagram

- Around line 490-501: The completePrompt timeout handling must treat timeoutMs:
0 as no SDK timeout, excluding the timeout option from the OpenAI client request
while preserving normal positive-timeout behavior. Update the affected provider
tests, including the ZooGatewayHandler coverage, to verify zero is omitted and
all providers handle this consistently.
In `@src/api/providers/opencode-go.ts`:
- Around line 167-180: Remove bridged abort listeners after every request
completes: in src/api/providers/opencode-go.ts:167-180, update createMessage to
name the handler and remove it in finally around the remaining flow, including
streamAnthropicMessage; in src/api/providers/unbound.ts:152-165 and
src/api/providers/vercel-ai-gateway.ts:71-86, remove the named handler in
finally around each stream-consumption loop; in
src/api/providers/zoo-gateway.ts:220-233, add the cleanup to the existing
try/catch via finally. A shared bridgeAbortSignal helper may centralize this
behavior if it preserves each provider’s existing abort handling.

…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).

… unbound - opencode-go createMessage: fast-fail with the standardized AbortError when the external signal is already aborted, before model-catalog work starts - opencode-go createMessage: detach the bridged abort listener in the Responses-format path via try/finally (it leaked one listener per request) - unbound createMessage: normalize mid-stream cancellations (after stream start) to the standardized AbortError, matching the pre-create catch - specs: assert the exact bridged-listener reference on the OpenAI/Anthropic/Responses paths and cover the new normalization branches
…5.1 temperature spec
The upstream/main sync (v3.82.0) brought in the Fable 5.1 temperature spec with a single-argument create assertion written against the pre-PR call shape. This branch's abort-signal change calls chat.completions.create(body, { signal }), so the assertion was stale and failed platform-unit-test (ubuntu-latest). Add the expected second argument as objectContaining({ signal: expect.any(AbortSignal) }), matching the sibling Fable 5 test.

stream that yields one chunk and then throws a specific ordinary Error; assert
the exact same error is propagated and its name is not "AbortError". Keep the
existing non-Error test unchanged and cover the ordinary-error path through the
