The follow-up track's tool-loop refactor moved
'from src.openai_compatible import send_openai_compatible,
OpenAICompatibleRequest, NormalizedResponse' to MODULE level
in src/ai_client.py. This violates the startup_speedup_20260606
invariant: heavy SDKs must not be loaded at module level because
ai_client.py is on the main thread's import chain.
src/openai_compatible.py line 5 does 'from openai import
OpenAIError, ...', so any import from it triggers the openai SDK
to load. test_ai_client_does_not_import_openai_at_module_level
guards this invariant and was failing.
Fix: move the imports back to local scope inside the function
bodies that need them:
- _default_send closure inside run_with_tool_loop
(imports send_openai_compatible)
- _send_grok (imports OpenAICompatibleRequest)
- _send_minimax (imports OpenAICompatibleRequest)
- _send_llama (imports OpenAICompatibleRequest)
- _send_gemini_cli (imports OpenAICompatibleRequest + NormalizedResponse)
Test patches: tests that previously patched
'src.ai_client.send_openai_compatible' now patch
'src.openai_compatible.send_openai_compatible' (the actual
import source). _execute_tool_calls_concurrently patches
unchanged (it's defined in src/ai_client.py itself).
Green confirmed: 62 vendor + tool + import-isolation tests
pass. 0 regressions.
5 Red tests in tests/test_ai_client_tool_loop.py verify the planned
run_with_tool_loop contract (no-tool-call fast path, tool-call
dispatch, max-rounds safety, history append, error tolerance).
Deviation from plan: tests patch src.ai_client.send_openai_compatible
(plan's Task 1.1 had src.tool_loop.send_openai_compatible). The plan
predates the AGENTS.md HARD RULE on src/<thing>.py files; per the
follow-up track's Naming Convention section, run_with_tool_loop lives
IN src/ai_client.py. The function body imports send_openai_compatible
from src.openai_compatible, so src.ai_client.send_openai_compatible
is the correct patch path.
state.toml: current_phase 0 -> 1, phase_1 pending -> in_progress,
t1_1 pending -> in_progress, blocked_by status
phase_6_in_progress -> phase_6_complete (parent's Phase 6

Confirmed red: 5 ImportError against src.ai_client.run_with_tool_loop
at collection time.
