One delegation implementation remains (src/agents/delegation.py).
Removed, after verifying zero live importers post-Phase-A/B:
- src/agents/coordination.py: CoordinationEngine, duplicate
delegate_to_librarian, AGENT_EXECUTORS/AGENT_STREAM_EXECUTORS
(only importer was its own test module)
- run_librarian_stream: documented-broken path (Ollama streaming +
tool call bug, PydanticAI #1292/#2256), only called by the deleted
coordination engine
- stream_delegate_to_* wrappers + STREAMING_DELEGATION_WRAPPERS and
the never-parsed __DELEGATION_RESULT__ marker in delegation.py
- HouseholdRegistry.get_streaming_delegation_tools() (no callers)
- tests/agents/test_coordination.py and the wrapper/stream tests
Note: the STREAMING_DELEGATION_WRAPPERS import in
src/responses/streaming.py was already removed by Phase A (7ce1c1a);
nothing to delete there.

- run_librarian / run_librarian_stream raise AgentError instead of
returning/yielding error text as normal output; detail stays in logs
- delegate_to_* wrappers now put a curated butler-toned sentence in
DelegationResult.output on failure and never expose str(e), so
streaming's error branch is reachable and honest
- _execute_single_delegation propagates success; direct delegation only
records delegate_to_* as called when the expert actually succeeded
- librarian tools return user-safe messages instead of
'Error searching: {e}' strings that leaked internal URLs into
synthesis; coordination stream errors are curated as well
- ruff cleanups (TYPE_CHECKING forward refs, B904, unused locals) in
the touched files to keep them lint-clean
