## Root Cause
After Pydantic migration, get_deals_by_radius() was attempting to validate
API responses as Deal objects. However, this endpoint returns POLYGON METADATA
(with fields: dealscount, polygon_id, settlementNameHeb), NOT individual deals.
All responses failed Pydantic validation (missing dealAmount, dealDate),
resulting in empty lists and 0 deals returned from ALL queries.
## Fixes Applied
### 1. client.py - get_deals_by_radius()
- Return type: `List[Deal]` → `List[Dict[str, Any]]`
- Remove Pydantic validation - return raw metadata dicts
- Update docstring to clarify this returns polygon metadata
- Add note to use find_recent_deals_for_address() for actual deals
### 2. client.py - find_recent_deals_for_address()
- Update to handle polygon metadata dicts (not Deal objects)
- Use dict.get('polygon_id') instead of model attribute access
- Rename variable: `nearby_deals` → `nearby_polygons` for clarity
### 3. fastmcp_server.py - get_deals_by_radius() tool
- Update to handle dict responses (not Deal objects)
- Remove strip_bloat_fields() call (not needed for metadata)
- Update docstring with WARNING about polygon metadata
- Change response keys: "deals" → "polygons", "total_deals" → "total_polygons"
### 4. Tests
- test_govmap_client.py: Update to expect dicts, not Deal objects
- test_fastmcp_tools.py: Update 3 tests to mock dict responses
## Impact
- ✅ find_recent_deals_for_address() NOW WORKS (was returning 0 deals)
- ✅ All 174 tests passing
- ✅ E2E API test confirmed working with real data
## API Behavior Documented
get_deals_by_radius endpoint design:
1. Returns polygon/area metadata (not individual deals)
2. Extract polygon_ids from metadata
3. Call get_street_deals(polygon_id) to get actual deals
4. This workflow is automated in find_recent_deals_for_address()

Fixed all remaining test failures after Pydantic v2 migration:
Core fixes:
- Date handling: Convert date objects to ISO strings across 4 files
- Model serialization: Use model_dump(mode='json') for JSON compatibility
- Optional fields: Made time_period_months Optional[int] in models
- Dict access: Replace .get() with getattr() for dynamic attributes
Test updates:
- Updated 50+ test fixtures from dicts to Deal models
- Fixed date-based tests to use recent dates for time filtering
- Added missing imports (CoordinatePoint, MarketActivityScore, DealStatistics)
- Updated assertions from dict keys to model attributes (snake_case)

Bug Fix:
- Fixed autocomplete_address tool to use correct API response fields
- Changed from non-existent fields (addressLabel, settlementNameHeb, coordinates)
to actual API fields (text, id, type, score, shape)
- Added coordinate parsing from WKT POINT format
- Impact: HIGH - tool was returning empty data for all fields
Test Coverage Report:
- Added comprehensive test coverage analysis
- Documented 34 passing tests
- Identified e2e test results for MCP tools
- Listed missing test cases and recommendations
- Overall assessment: Good coverage, one bug found and fixed
E2E Test Results:
- ✅ find_recent_deals_for_address - WORKING
- ✅ analyze_market_trends - WORKING
- ✅ get_valuation_comparables - WORKING
- ✅ autocomplete_address - FIXED (needs MCP server restart to take effect)

Problem:
- get_valuation_comparables failed with 61,565 tokens (exceeded 25K MCP limit)
- Large MULTIPOLYGON shape data consumed ~40-50% of response tokens
- Not useful for LLM analysis, only bloating responses
Solution:
1. Added strip_bloat_fields() helper to remove:
- shape: Large coordinate data
- sourceorder: Internal ordering field
- source_polygon_id: Internal reference field
2. Applied to 5 MCP tools returning deal data:
- get_deals_by_radius
- get_street_deals
- find_recent_deals_for_address
- get_neighborhood_deals
- get_valuation_comparables
3. Reduced get_valuation_comparables default max_comparables: 200 → 50
Results:
- Token usage reduced by ~87% (61K → ~7-8K tokens)
- All tools now work within MCP token limits
- Cleaner, more efficient responses
- No loss of useful data for LLM analysis

Refactor repetitive try-except blocks using _safe_calculate_metric helper
function to reduce code duplication and improve maintainability.
Changes:
- Add _safe_calculate_metric helper to centralize error handling
- Remove misleading default values (0/"unknown") in summary fields
- Use None defaults instead to clearly indicate unavailable data
- Add final newline to file per convention
This prevents LLMs from misinterpreting 0 as "zero investment potential"
when it actually means "data unavailable".
