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).
