Phase 3 (1 of 9 cruft sites obliterated):
The legacy wrapper _resolve_and_check(raw_path) returned tuple[Path|None, str],
dropping the structured ErrorInfo from _resolve_and_check_result. Callers in
dispatch_tool_call (py_remove_def, py_add_def, py_move_def, py_region_wrap) used
the pattern 'p, err = _resolve_and_check(path); if err: return err' which is
exactly the false drain the user wants obliterated.
Migration:
- DELETED: _resolve_and_check wrapper (lines 175-188 in src/mcp_client.py)
- UPDATED: 5 callers in dispatch_tool_call now call _resolve_and_check_result
directly with .ok check + NilPath check + structured error routing
- UPDATED: 4 test files that monkey-patched _resolve_and_check to mock the
Result helper instead:
- test_mcp_ts_integration.py (1 mock)
- test_ts_c_tools.py (2 mocks)
- test_ts_cpp_tools.py (8 mocks)
- test_cruft_removal.py (NEW; 4 tests including the wrapper-obliterated
invariant + the audit-script-finds-zero invariant + 2 dispatch tests)
Test result: 51/51 pass (31 baseline + 16 heuristic + 4 cruft).
Audit gate: src/mcp_client.py --strict exits 0 (no new violations introduced).
Baseline audit: --include-baseline --strict exits 1 only due to 4 pre-existing
non-baseline INTERNAL_RETHROW sites in outline_tool.py / warmup.py /
vendor_capabilities.py (out of scope per spec).
The wrapper IS DELETED. No pass-through. No backward compat. The dead code dies.
