For modelProviders-backed models the provider entry's generationConfig wins over model.generationConfig; built-in Qwen OAuth models ignore settings and only honor QWEN_STREAM_IDLE_TIMEOUT_MS. QWEN_STREAM_MAX_LIFETIME_MS controls the lifetime cap; 0 disables either. Fix status: documented_behavior Limitations: - Source is the published @qwen-code/qwen-code 0.24.6 npm bundle (minified chunks and locale files); behaviour may differ in other versions. - Not reproduced in this session. Other error fragments: - provider configuration takes precedence, so model.generationConfig is ignored for those models. - Built-in Qwen OAuth models cannot be overridden via settings. - Stream exceeded its ${maxLifetimeMs}ms upstream-wait cap after ${chunksReceived} chunks without completing Evidence (public sources, summarized; not reproduced by this contributor): - https://registry.npmjs.org/@qwen-code/qwen-code/-/qwen-code-0.24.6.tgz#package/chunks/chunk-5NIA2UGW.js (official_docs, unknown, documented_behavior): StreamInactivityTimeoutError and StreamLifetimeExceededError messages describe precedence (provider config over model.generationConfig; built-in OAuth models env-only) and 0-to-disable. - https://registry.npmjs.org/@qwen-code/qwen-code/-/qwen-code-0.24.6.tgz#package/chunks/chunk-Q25FO5UE.js (official_docs, unknown, documented_behavior): Defines QWEN_STREAM_IDLE_TIMEOUT_MS and QWEN_STREAM_MAX_LIFETIME_MS env names.
