"""Integration tests for /api/tool-calls/* router (Sprint 4.1).
Target routes (7):
- GET /api/tool-calls/{session_id}
- GET /api/tool-calls/{session_id}/{tool_call_id}
- POST /api/tool-calls/{session_id}/{tool_call_id}/offload
- POST /api/tool-calls/{session_id}/{tool_call_id}/cancel
- POST /api/tool-calls/{session_id}/{tool_call_id}/extend-deadline
- GET /api/tool-calls/{session_id}/{tool_call_id}/output
- GET /api/tool-calls/{session_id}/{tool_call_id}/stream
Coverage strategy:
1. Empty-session contract (list returns empty, all detail routes 404).
2. Body validation (extend-deadline requires seconds>0 or no_deadline).
3. Cross-session 404 guard using an unknown tool_call_id.
4. Governance ASK path smoke — set session-level approval_level
``always_ask`` through the console chat body and verify the pending
approval surfaces (tool_adapter.py:_ask_user_approval branch).
The tool_call entry is popped from ``coordinator._entries`` the moment
the tool finishes, so live inspection of an in-flight tool call is not
feasible with the built-in ``get_current_time`` (sub-millisecond). The
existing cron + security tests already exercise the runtime middleware
chain end-to-end (test_cron_execution::test_cron_agent_tool_call_execution
and test_security_real::test_tool_guard_blocks_dangerous_shell_via_agent_run);
here we focus on the HTTP router contract + governance approval branch.

Test purpose:
- Verify the frontend session-level approval override (PR #5685)
propagates through console → runtime → PolicyGuardedTool and
the ``is_disabled()`` branch at ``tool_adapter.py:207-211``
fires when ``approval_level=off``.
Test flow:
1. Register mock LLM provider (get_current_time tool_call).
2. Submit /console/chat/task with request_context.approval_level=off.
3. Poll task status until finished.
4. Verify the governance log records the ``approval_level=off``
short-circuit for at least one tool call in the session.
We use ``off`` (not ``always_ask``) because:
- ``always_ask`` is not a valid ``ToolExecutionLevel`` value
(enum: off/auto/smart/strict) — the ``from_config`` fallback
would coerce it to AUTO which yields tool-specific decisions.
- ``off`` guarantees the is_disabled() early return branch,
deterministically exercising the request_context plumbing.
- The alternative (``strict`` forces ASK on every tool) requires
a synchronous approval reply and depends on the ApprovalService
wiring, which is out of scope for Sprint 4.1.
