The gateway hardcoded "stop" on every terminating stream chunk, so tool-call rounds reported finish_reason=stop and length caps were invisible to clients. UnifiedChunk now carries finish_reason; adapters emit it (with empty-string finish reasons like sensenova treated as non-terminal), standardSSEChunk passes it through for un-adapted upstreams, [DONE] no longer emits a duplicate reason-less done chunk, and both streaming paths emit the real reason with "stop" as fallback. Also vendor sensenova/agentrouter adapters into the repo: they were WebUI-only uploads and a deploy sync silently removed them while live AUTO-chain slots still referenced them.
