"""Live integration tests for the spec-search subsystem.

These tests use REAL API calls (CloudEngine with Anthropic) and real
TraceStore data. They are gated on the ``cloud`` marker — skip them
with ``pytest -m "not cloud"``.

Requires:
- ANTHROPIC_API_KEY environment variable set
- TraceStore at ~/.openjarvis/traces.db with some traces
