Automated dead code audit using vulture + coverage.py + ast-grep intersection, confirmed by Opus deep verification pass. Every symbol verified to have zero production callers (test imports excluded from reachability analysis). Removes ~1,534 lines of dead production code across 46 files and ~1,382 lines of stale test code. 3 entire files deleted (agent/builtin_memory_provider.py, hermes_cli/checklist.py, tests/hermes_cli/test_setup_model_selection.py).
