… fail on '(empty)' sentinel Two related bugs caused subagent delegation to silently return empty summaries with 0 tokens when the user configured delegation.provider=bedrock alongside delegation.base_url=https://bedrock-runtime.<region>.amazonaws.com. Root cause #1 — misrouting in _resolve_delegation_credentials(): The configured_base_url branch unconditionally forced provider='custom' and api_mode='chat_completions', only specializing for chatgpt.com, anthropic, and kimi hosts. Bedrock (and other native-SDK providers) fell through as 'custom' + chat_completions, which then POSTed OpenAI-shaped JSON at Bedrock's native API. Bedrock rejected the payload and returned nothing, which looked like an empty LLM response to the child agent. Fix: when provider is one of {bedrock, vertex, google, google-genai}, skip the base_url short-circuit and fall through to resolve_runtime_provider(), which knows how to construct the proper SDK client. base_url can still be forwarded through that path for regional overrides. Root cause #2 — '(empty)' sentinel accepted as success: After N retries of empty LLM responses, run_agent.py emits the literal string '(empty)' as final_response. _run_single_child then hit `elif summary:` — '(empty)' is truthy, so status became 'completed' and the parent surfaced a blank result with no error. Users saw api_calls=4, tokens=0, duration~0.4s, status=completed. Fix: treat final_response.strip() == '(empty)' as a failure so the parent surfaces it instead of silently accepting zero-content 'success'. Both paths were reproduced in a live Hermes TUI session on us-west-2 Bedrock (provider=bedrock, model=us.anthropic.claude-sonnet-4-6) and are covered by new tests in tests/tools/test_delegate.py.
