Phase 8 of startup_speedup_20260606 track.
Part 1: app_controller.py cleanup
- Removed 'import requests' (was used in 2 places - lazy import added inside)
- Removed 'import tomli_w' (dead import; never referenced in app_controller)
- Migrated 2 threading.Thread spawns to use self.submit_io (the do_post
closures in _handle_approve_ask and _handle_reject_ask)
Part 2: Main thread purity enforcement test
- tests/test_main_thread_purity.py: 7 tests verify that the 6 refactored
files (ai_client, app_controller, commands, theme_2, markdown_helper,
gui_2) have ZERO top-level imports from the heavy denylist:
{google.genai, anthropic, openai, requests, google.genai.types,
fastapi, fastapi.security.api_key, src.command_palette,
src.theme_nerv, src.theme_nerv_fx, src.markdown_table, numpy,
tkinter, tomli_w}
This is the static enforcement (the runtime audit-hook test using
sys.addaudithook is a follow-up).
The test is RED before each refactor phase, GREEN after. If a future
commit re-introduces a heavy import in one of these files, the test
fails immediately in CI.
TESTS:
- 7/7 main thread purity tests PASS
- 15/15 log + app controller tests still PASS (no breakage from
removing requests/tomli_w imports)
