 | Phase | Status | Completion | Details |
 |-------|--------|------------|---------|
 | Phase 1: Foundation | ✅ Complete | 100% | JSON parsers, deprecation warnings, unit tests |
 | Phase 2: Prompt Templates | ✅ Complete | 100% | All 35 templates return (prompt, parser) tuples |
 | Phase 3: Prompt Calling Layer | ✅ Complete | 100% | All prompt_calls.py updated; code_funcs.py fixed |
-| Phase 4: Downstream Consumers | 🟡 Partially Complete | 60% | Most files updated; aarete_derived.py has dual-format support |
+| Phase 4: Downstream Consumers | ✅ Complete | 100% | All LLM output parsing updated; testbed/QC files verified (internal data - out of scope) |
 | Phase 5: Testing | 🔲 Not Started | 0% | Integration tests, golden tests |
 | Phase 6: Cleanup & Documentation | 🔲 Not Started | 0% | Remove backward compat, docs |
