Bug: When the Govmap API returns the same polygon_id multiple times
(which can happen for addresses with multiple associated polygons),
the code was processing each duplicate separately, leading to:
- Duplicate API calls for street/neighborhood deals
- Wasted API quota and slower performance
- Confusing logs showing same polygon queried multiple times
Example from logs:
INFO: Querying polygon 53283601 (distance: 0m from search point)
INFO: Getting street deals for polygon: 53283601
INFO: Querying polygon 53283601 (distance: 0m from search point)
INFO: Getting street deals for polygon: 53283601
Root cause:
- nearby_polygons API response can contain duplicate polygon_ids
- Code was appending all polygons without deduplication
- Log message claimed "unique polygon IDs" but didn't enforce it
Solution:
- Use dict to deduplicate polygons by polygon_id (lines 612-643)
- When duplicates exist, keep the one with shortest distance
- Convert dict to list after deduplication
- Now truly have unique polygon IDs as the log claims
Impact:
- Reduces API calls (fewer duplicates = less load on Govmap API)
- Faster queries (less redundant processing)
- Clearer logs (no confusing duplicate entries)
- Better performance for addresses with many associated polygons
