# T03: All 4 pipeline stages now use per-stage model/modality config with INFO logging

**All 4 pipeline stages now use per-stage model/modality config with INFO logging**

## What Happened

Updated all 4 pipeline stages (2-5) to call _get_stage_config and pass modality + model_override to llm.complete(). Each stage now logs which model/modality it's using at INFO level. Updated _safe_parse_llm_response to pass modality/model_override through to the retry call.

## Verification

_get_stage_config imports and returns correct defaults

## Verification Evidence

| # | Command | Exit Code | Verdict | Duration |
|---|---------|-----------|---------|----------|
| 1 | `cd backend && python3 -c "from pipeline.stages import _get_stage_config; m, mod = _get_stage_config(2); print(f'model={m}, modality={mod}')"` | 0 | ✅ pass — model=None, modality=chat | 300ms |
