     - VC_no_configs_in_src: 0 .ini files in src/ (PASS via phase4_audit.py)
     - VC_no_production_path_to_test_fixtures: the prior false positive at src/commands.py:371 (the line removed in Phase 3 commit 3b966288) is gone. Remaining hits in src/gui_2.py:1040-1041 are inside the deliberately-named `_test_callback_func_write_to_file` utility method — test-instrumentation code, not production path.
 - [N/A] Task 4.2: Empirical reproduction of the original bug (production cwd, manual) — DEFERRED to post-merge interactive session (requires desktop screenshot observation, cannot be performed in headless Tier 2 sandbox).
