Merge Risk: 🟡 Moderate · up to Opencode Go cancellation and timeout behavior remains incomplete for Responses requests and model lookup. Affected requests may ignore configured timeouts, delay cancellation, or return the wrong error type, so these issues should be fixed before merge. 🚥 Pre-merge checks | ✅ 5 | ❌ 2❌ Failed checks (2 warnings)

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.

- 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

finally around each stream-consumption loop; in

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).

This OpenAI-path catch checks abort before wrapping. The Responses-path catch at line 887 wraps without that check — if { signal: options?.abortSignal } triggers an APIUserAbortError, does it normalize to createAbortError or surface as "Opencode Go completion error: ..."?

The anthropic path (line 267) and openai path (line 323) both have a catch that normalises APIUserAbortError to createAbortError. If the external signal fires mid-stream on this responses path, does APIUserAbortError propagate unchanged to the caller?

This streamAnthropicMessage pre-stream catch guards abort before wrapping. streamResponsesMessage at line ~465 has a similar pre-stream catch — does it have the same guard, or would an early abort surface as a wrapped error?

fetchModel() at line 136 completes before this bridge is wired. If the external signal fires during model resolution, is the abort silently dropped? opencode-go races this step via rejectOnAbort and has a mid-resolution test at opencode-go.spec.ts:523.

fetchModel() at line 62 runs before this bridge is established. If the signal fires during model resolution, is the cancellation handled?

Same question as UnboundHandler and VercelAiGatewayHandler: fetchModel() at line 187 runs before this bridge. Is a mid-resolution abort handled here?

None of the four providers call throwIfAborted at line 46 — they each inline createAbortError(providerName) directly. Is throwIfAborted here for a planned follow-up, or can it be removed?

The three sibling providers (vercel-ai-gateway.ts:164, zoo-gateway.ts:293, opencode-go.ts:366) check only controller.signal.aborted here. Should these providers align on the wider condition (safer), or is there a reason unbound needs the extra instanceof checks?

The opencode-go equivalent (lines 690–697) captures the exact listener reference from spy.mock.calls and asserts the same reference in both addEventListener and removeEventListener. expect.any(Function) here would pass even if a different function is removed — should this use the same reference-identity pattern?
