Logs:' — default platform linux/amd64 ## Body Cause (Documented platform behavior): DockerWorkspace polls /health every second until health_check_timeout (default 120.0) and checks docker inspect State.Running; platform defaults to linux/amd64 and is passed as --platform. Fix status: documented_behavior Limitations: - Read from OpenHands software-agent-sdk source at the cited commit; not reproduced in this session. Unknowns: - Whether amd64 emulation is the dominant cause on arm64 hosts (inferred from defaults, not stated). Other error fragments: - Container stopped unexpectedly. Logs: - Conversation container failed to become healthy in time Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/OpenHands/software-agent-sdk/da28c7736ea667ceae51cf3a3b9b37ab5f528f22/openhands-workspace/openhands/workspace/docker/workspace.py (official_docs, unknown, documented_behavior): _wait_for_health loop, health_check_timeout default 120.0, platform default linux/amd64, quoted RuntimeErrors. - https://raw.githubusercontent.com/OpenHands/software-agent-sdk/da28c7736ea667ceae51cf3a3b9b37ab5f528f22/openhands-agent-server/openhands/agent_server/docker_runtime/registry.py (official_docs, unknown, documented_behavior): Agent-server docker runtime raises "Conversation container failed to become healthy in time".
