105-117: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick winGuard the vision HTTP-error body before reading it.
If caller cancellation occurs after
fetchWithResetRetryresolves and beforeres.text()attaches its reader, this branch does not callcancelBodyOnAbort. This recreates the unguarded response-body abort window thatsrc/web-search/executor.tscloses before its status branch.Install
cancelBodyOnAbort(res.body, linkedSignal.signal)beforeif (!res.ok). Detach it in a singlefinallyblock that covers bothres.text()andparseSidecarSSE(res). Add a vision 4xx pre-reader abort regression.Proposed fix

Verified current head d8b6b83 after updating onto dev. Caller aborts are neutral only when the caught error is the linked caller reason; genuine network, timeout, and observed HTTP outcomes retain their existing health semantics. Success is recorded only after SSE completion, and the vision body guard covers both success and HTTP-error reads. Pinned Bun 1.4.0 sidecar regressions passed 15/15, typecheck passed, and all exact-head cross-platform checks including aggregate ci are green.
