…utils Extend src/api/providers/utils/abort-signal.ts with the abort-signal series helpers used by the gateway providers: - isRequestAborted(error, signal): wider abort detection - an aborted signal, a DOM AbortError, the OpenAI/Anthropic SDK APIUserAbortError (name check), or the exact SDK abort message "Request was aborted." - trusting name/message only on real Error instances so a plain object that merely looks like an abort propagates unchanged - createAbortError(providerName): fresh error satisfying the Task.ts abort contract (name "AbortError", message ending in "aborted") - rejectOnAbort(pending, signal, providerName): settle a signal-less async phase (model discovery) on the provider AbortError when the signal fires first; the abort listener detaches when pending settles - resolveModelWithAbort(fetchModel, signal, providerName): run model resolution inside a cancellation scope - entry fast-fail for a pre-aborted signal, the rejectOnAbort race while the lookup is pending, and normalization of abort-flavored lookup failures; any other resolution failure propagates unchanged Includes direct unit tests for the resolveModelWithAbort cancellation scope (pre-aborted fast-fail, no-signal pass-through, mid-resolution race, abort normalization, non-abort propagation), the isRequestAborted instanceof tightening tests, and the settle-guard test utility. Unit 1/3 of the Zoo-Code-Org#1295 split (content source: 62f596c5d). Part of the abort-signal series (round 1). Builds on Zoo-Code-Org#674, Zoo-Code-Org#901, Zoo-Code-Org#1008. Addresses Zoo-Code-Org#404.

this.resolveModel()without the caller signal. Two gaps follow. A caller that aborts before or during the catalog fetch does not fail fast; the request still starts after resolution completes.

- createMessage: bridge metadata.abortSignal to a per-request AbortController (Bedrock pattern: pre-aborted guard, once-listener, detached on completion so a task-scoped signal does not accumulate listeners); model resolution runs inside the shared resolveModelWithAbort cancellation scope (pre-aborted fast-fail, mid-resolution race) - aborted/timeout requests normalize to the provider AbortError on all three wire formats (anthropic /v1/messages, responses /v1/responses, openai chat completions), both pre-stream and mid-stream; non-abort failures keep the wrapped "Opencode Go completion error:" identity - the OpenAI branch runs message conversion and request construction inside the same cleanup scope as the Anthropic and Responses branches, so a conversion failure (e.g. an unstringifiable tool input) still detaches the bridged abort listener (CodeRabbit fix on this PR) - completePrompt: forwards abortSignal/timeoutMs to all three SDK paths (timeoutMs <= 0 omits the SDK timeout option, since the SDK treats timeout: 0 as an immediate abort); aborted completions and APIConnectionTimeoutError/APITimeoutError normalize to the provider AbortError (series standard) The two inner pre-stream guard mutants (the abort-normalization condition and its provider-name literal) are documented as provably equivalent with mutator-specific Stryker directives: createMessage's outer catch applies the identical isRequestAborted check to the same controller signal and re-standardizes, so the inner layer's only unique behavior is the non-abort completion-error wrap (stays kill-tested). The cleanup-scope re-indentation made the gate instrument pre-existing request-construction lines for the first time; their previously unobservable mutants are kill-tested: R1 tool-result merge shape for preserveReasoning models and the plain shape for non-preserveReasoning models, the includeMaxTokens on/off branches with a ceiling-bounded model, and the parallel_tool_calls default/explicit-false. Unit 2/3 of the Zoo-Code-Org#1295 split (content source: 62f596c5d); stacks on the shared-util unit. Part of the abort-signal series (round 1). Builds on Zoo-Code-Org#674, Zoo-Code-Org#901, Zoo-Code-Org#1008. Addresses Zoo-Code-Org#404.

Wires the external abort signal and per-request timeout into the
completePrompt(non-streaming) andcreateMessage(streaming) paths of the Opencode Go provider. Stacks on the shared-util unit of this split (resolveModelWithAbortinutils/abort-signal.ts).completePrompt: forwardsoptions?.abortSignal/options?.timeoutMsto all three wire formats (Anthropic/v1/messages, OpenAIchat.completions, and the Responses/v1/responsespath);timeoutMs <= 0omits the SDK timeout option (the SDK treatstimeout: 0as an immediate abort); aborted completions and SDK connection/timeout errors normalize to the provider AbortError.createMessage: bridgesmetadata?.abortSignal(Bedrock pattern: pre-aborted guard,{ once: true }listener, detached on completion so a task-scoped signal does not accumulate listeners) into a per-requestAbortControllershared by all three streaming wire formats; model resolution runs inside the sharedresolveModelWithAbortcancellation scope (pre-aborted fast-fail, mid-resolution race).Tests:
completePromptpass-through tests (signal, timeoutMs incl. 0, and no-options backward compatibility) for all three wire formats, plus normalization/identity tests for aborted and timed-out completions.createMessagebridging tests: pre-aborted signal -> rejects with the standardized AbortError before any request work; abort mid-resolution -> settles on the standardized AbortError before the lookup is released; mid-stream abort on each wire format -> standardized AbortError; detach tests use the reference-identity pattern (the resolution race registers its own listener, so the bridge is the last "abort" registration).Series and unit
Unit 2/3 of the #1295 split (content source:
62f596c5d); stacks on the shared-util unit.Part of the abort-signal series (round 1). Builds on #674, #901, #1008. Addresses #404.
Review response (maintainer review of #1295)
completePromptcatch now has the same abort normalization as the OpenAI path (isRequestAborted(error, options?.abortSignal) || error instanceof APIConnectionTimeoutError-> provider AbortError), pinned by "preserves abort identity on the Responses completion path" and "surfaces Responses request timeouts as an AbortError in completePrompt".streamResponsesMessagehas the same pre-stream guard asstreamAnthropicMessage(aborted/timeout requests normalize instead of wrapping).resolveModelWithAbort, unit 1/3); opencode-go's pre-aborted fast-fail happens before any catalog/SDK work (pinned: catalog and SDK both uncalled).createMessagecatch uses the widerisRequestAbortedcondition (aborted signal, DOM AbortError, SDK APIUserAbortError, exact "Request was aborted." message; name/message checks require a realErrorinstance).Evidence
CodeRabbit fix (post-review)
CodeRabbit's finding on this PR (cleanup terminal paths): the OpenAI branch converted messages and built the request body before its
try/finally, so a conversion failure (e.g. an unstringifiable tool input) left the bridged abort listener attached. Fixed:includeMaxTokenson/off branches with a ceiling-bounded model, and theparallel_tool_callsdefault/explicit-false).Equivalence note (directive proofs)
Two of the directives cover provably-equivalent inner-guard mutants.
createMessagewraps theyield*of each streaming generator in an outercatchthat applies the identicalisRequestAbortedcheck to the same per-request controller signal and re-throws the standardized AbortError. Therefore:name === "AbortError", so the outer re-standardizes with the correct provider name and the inner literal is unobservable.The inner layer's unique, kill-tested behavior is the non-abort "Opencode Go completion error:" wrap.
