# P1: Improve retrieval fallback ordering

- Objective: Improve the look of the UI
- Release: 
- Risk: low
- Auto apply safe: True

## Problem
Low-confidence drafts still occur when release-filtered retrieval returns no hits.

## Change
Add deterministic fallback chain and expose retrieval diagnostics in API responses.

## Files
- `app.py`

## Tests
- Call /assistant/draft with missing release_name and verify non-empty sources fallback.
