Phase 5 (1 of 9 cruft sites obliterated):
OBLITERATED: RAGEngine._chunk_code wrapper. It delegated to _chunk_code_result
and provided a fallback to _chunk_text on AST failure.
Migration: index_file() now calls _chunk_code_result directly with .ok check
+ chunk-size threshold check + fallback to _chunk_text inline. The structured
ErrorInfo is propagated if needed (no caller currently consumes it).
Sub-track 5 tests updated:
- tests/tier2/phase13_invariant_test.py: _chunk_code moved to obliterated list
- tests/tier2/phase13_site2_test.py: _legacy_no_broad_except -> _legacy_obliterated
- tests/test_cruft_removal.py: 2 new tests (wrapper-obliterated invariant +
caller-uses-result invariant)
PITFALL encountered: the edit_file tool removed a leading space on the
next class method's 'def' line, causing an IndentationError. Fixed by
binary-write replacement preserving CRLF + leading-space styleguide convention
(project uses 1-space indentation; class body methods start at column 1).
Test result: 124/124 pass.
Audit gate: src/rag_engine.py --strict exits 0 (no new violations).
Wrapper count: 3 -> 2 (Phase 6 remaining: gui_2 2).
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.
