Phase 1, Tasks T1.2 + T1.4 of the startup_speedup_20260606 track.
NEW: scripts/audit_main_thread_imports.py
Static CI gate that AST-walks the import graph reachable from
sloppy.py and fails (exit 1) if any heavy module is imported at the
top of a main-thread-reachable file. Walks into if/elif/else and
try/except branches (which run at import time) but skips function
bodies (which only run when called). Allowlist: stdlib + the lean
gui_2 skeleton (imgui_bundle, defer, src.imgui_scopes, src.theme_2,
src.theme_models, src.paths, src.models, src.events).
NEW: scripts/audit_gui2_imports.py
Read-only analysis tool that lists every top-level and function-level
import in src/gui_2.py, classified by location. Used in Phase 5D to
identify which imports to remove.
NEW: tests/test_audit_main_thread_imports.py
9 tests covering: --help exits 0, clean stdlib-only passes, heavy
third-party fails, google.genai fails, transitive walks, function-
body imports ignored, if-branch imports flagged, try-block imports
flagged, file:line reported. All 9 pass.
NEW: docs/reports/startup_baseline_20260606.txt
3-run median cold-start benchmark. Worst offenders: src.gui_2
(1770ms), simulation.user_agent (1517ms), google.genai (1001ms),
openai (482ms), anthropic (441ms), imgui_bundle (255ms),
src.theme_nerv* (485ms combined), src.markdown_table (243ms),
src.command_palette (242ms).
NEW: docs/reports/startup_audit_20260606.txt
Audit output on the CURRENT codebase. Reports 67 violations across
the main-thread import graph (incl. numpy in src/gui_2.py:9,
tomli_w in src/gui_2.py:18, fastapi + requests in src/app_controller,
tree_sitter_* in src/file_cache, pydantic in src/models, plus all
the src.* subsystem imports that drag in heavy transitive deps).
Phase 3-5 of the track will resolve these one by one.
After Phase 3-5, this audit must exit 0 (no violations).
Co-located reports in docs/reports/ per project convention; the other
agent finished their work in docs/superpowers/ and is unrelated.
The AI client decoupling was never properly implemented and added
unnecessary complexity. The actual startup bottleneck was RAG initialization
which is now handled via async initialization.
